                          ABSTRACT
A compilation of abstracts summarizing articles from a variety
of technical publications constituting the problem of urban
drainage was developed by the Franklin Institute Research
Laboratories.  The' present work includes 599 abstracts of
documents published for the most part from July 1968 through
June 1970.  The abstracts are classed in ten sub-topic
categories and arranged alphabetically by author and numerically
by abstract number within each category.  Each item includes
a bibliographic citation, an abstract, and a set of indexing
descriptors and identifiers.  A cumulative subject index at
the end of the volume provides the necessary access to individual
concepts.  An author index and journal list are also included.

This work was submitted in fulfillment of Contract 14-12-904
between the Federal Water Quality Administration and the
Franklin Institute Research Laboratories.

Key Words: Storm runoff, urbanization, drainage systems, overflow,
rainfall-runoff relationships, sewers, sewage treatment, water
pollution control.

                        FOREWORD
SELECTED URBAN STORM WATER RUNOFF ABSTRACTS is a compilation
of abstracts summarizing articles from a variety of technical
publications, covering the subjects of urban runoff, storm
water drainage, storm sewers, and legislation — together
constituting "the problem of urban drainage".  Articles on
more general'subjects, such as "sewerage" or "sanitary
engineering", and topics not closely related to storm water
have been excluded.

The present work includes 599 abstracts of documents published
from July 1968 through June 1970.  A few abstracts summarize
material published before this period that were not included
in  the previous volume of SELECTED URBAN STORM WATER RUNOFF
ABSTRACTS, published in June 1969.  For convenience, the abstracts
are classed in ten sub-topic categories and arranged alphabetically
by author and numerically by abstract number within each category.
Since most of  the papers fit into more than one category, a
cumulative subject index at the end of the volume provides the
necessary access to individual concepts and should be utilized
for locating all abstracts in which this concept is significant.
The numbers following an index term are the numbers for the
abstracts in which this term is found.  Each item includes a
bibliographic citation, an abstract, and a set of indexing
descriptors (subject terms listed in the WATER RESOURCES
THESAURUS, November 1966 edition) and identifiers (newly
suggested index terms).  The most important index terms are
marked by an asterik.  An author index and journal list are
included for the reader's benefit.

Copies of the articles abstracted in most cases can be obtained
from research libraries covering water pollution or public
health engineering literature.

Suggestions concerning the improvement of content and format,
or expansion of subject coverage in future supplements to this
compilation, which will be issued quarterly, will be gratefully
received.

APPLIES EXISTING TECHNOLOGY FOR A CLEANER LAKE ERIE ,


Am City, Vol 85, No 4, p 18, Apr 1970,

Descriptors:  *Waste treatment,  ^Storage, Instrumentation, Storm runoff.
Identifiers:  *Lake Erie, Monitoring system,  Stormwater storage.

The Detroit Metropolitan Water Service  is putting existing technology
into effect to help decelerate the aging of Lake Erie.   Proposed pro-
grams include:  solids reduction by addition  of mechanisms to the
regional wastewater plant, coliform removal through chlorination, phos-
pkr"e reduction using pickle liquor from steel mills, waste oil and
grease removal using oil skimmers, construction of phenol-removing
systems, and installation of smokestack air cleaners  to prevent air
pollution.  A monitoring system  to reduce stormwater  overflows  is also
being built to warn of approaching rainfall,  thus allowing sewers to
be pumped before the storm.   This will  permit sewers  to store contami-
nated stormwater, the dirtiest water being sent to the  treatment plant.
Further long range plans are being made to meet future  demands  of the
region.

STEEL PIPE SELECTED FOR STORM SEWER SYSTEM,
Am City, Vol 85, No 3, p 22, Mar 1970.

Descriptors:  *Pipes, Construction costs.
Identifiers:  Steel pipes, Storm sewers,  Sewer system.

Steel piping instead of the more-commonly used reinforced concrete was
employed to construct a storm sewer system in Lakewood,  New York.   Ad-
vantages of this material include its  strength, lighter  weight,  and
lower cost.  Savings in material cost  alone were about  15%, and lower
labor costs were incurred because steel is simpler to handle than other
materials.  Dimensions of the storm sewer system are given.

UNDERWATER SEWAGE STORAGE AN AID TO POLLUTION ABATEMENT,


Am City, Vol 84, No 9, pp 30 and 34, Sep  1969.

Descriptors:  ^Construction materials,  Storm runoff, Pollution abatement,
Waste storage,  Overflow.
Identifiers:  *Rubber storage containers,  Storm tank, Anacostia River.

-------
Goodyear Tire & Rubber Co. and Underwater Storage, Inc. of Washington
B.C. have announced a joint project to attack water pollution by collect-
ing wastes in huge, collapsible, underwater, rubberized tanks.  Two
prototype systems are being tested in the Anacostia River in Washington;
one to trap stormwater overflow, and the other near a marina to collect
wastes from boats.  These storage tanks could resolve a variety of prob-
lems such as threats of river fires caused by accidentally-ignited oily
wastes, and pollution from stormwater which was previously eliminated
only through costly sewer reconstruction.

UNDERWATER LINE SPANS 32 FEET BETWEEN 'SUPPORTS,
Am City, Vol  84, No  8, p 58, Aug 1969.

Descriptors:   *Concrete pipes, *Installation, *Construction equipment.
Identifiers:   *Underwater pipeline.

An underwater pipeline of prestressed concrete units was installed in
St. John's  River as  an outfall sewer from a waste treatment plant to
serve  a new industrial area of Jacksonville, Florida.  Double sections
of cylinder pipe were laid on concrete piles topped with precast con-
crete  caps  to cradle the pipe.  Scuba divers guided and joined pipe
sections.   Extensions  and  other installation techniques are given.

 IT'S IN THE BAG,
 Am City, Vol 84, No 4, p 88, Apr 1969.

 Descriptors:  *Storage tanks, Overflow,  Storm runoff,  Ohio.
 Identifiers:  *Rubber storage containers,  Combined sewers,  Storm tank.

 The problem of stormwater overflows from combined sewers  is  being corn-
 batted in Sandusky, Ohio through the implementation of a  plan which  is
 much less costly than the common solution  of sewer separation.   The  new
 system consists of rubberized storage reservoirs  that  trap  the heavily-
 polluted "first flush" of stormwater. When the storm  ends,  pumps trans-
 fer the stored stormwater to the treatment plant  for processing  along
 with the normal wastewater.   Costs, details,  and  a diagram  of the system
 are included in the article.

 SCREEN  TREATMENT FOR SEWER OVERFLOWS,
 Am  City,  Vol  84, No  3, p 24, Mar 1969.

 Descriptors:   *Screens, Storm runoff, Overflow, Oregon.
 Identifiers:   *Runoff treatment, Combined sewers.

 An  alternative to  separation of combined sewers in Portland, Oregon  is
 being tested  under a FWPCA grant.  The experimental pilot plant includes
 high-rate,  fine-mesh screens which treat overflow that is pumped to  the
 plant during  periods of heavy rainfall.  Previously, only one-third  of
 the rainy season flow was treated while the remainder was discharged un-
 treated into  a receiving stream.  A description of the structure and
 workings  of the screen operation is given.  Laboratory tests will deter-
 mine the  effectiveness and feasibility of the system.

 TRENCHER AND  BOX SHIELD MAKE SEWER JOB ALMOST ONE-RIG OPERATION,


 Construct Methods  Equip, Vol 51, No 4, pp 134-135, 138-140  and 143,
 Apr 1969.  8  fig.

 Descriptors:   ^Excavation, ^Construction equipment, *Cost analysis.
 Identifiers:   ^Hydraulic trencher, *Storm sewers, "Guidance system,
 Oakland,  Michigan, Laser beam.

 A tractor-powered  hydraulic trencher used a three-line bucket arrange-
 ment to perform digging for a 43,000-foot storm sewer in Oakland,
 Michigan.  A  box shield moved ahead 28 inches at a time and carried  a
 hopper to distribute gravel for the pipe bed.  Job difficulties held
 cost savings  to about 10% below conventional backhoeing, but the trench-
 er  did protect against cave-ins in addition to providing safety in open-
 ing a trench  parallel to gas and water lines.  The trencher had three
 basic components:  (1) a standard Cat D9 up front; (2) a ladder type
 bucket line and transverse unloading conveyer; and (3) a hydraulically
 powered telescoping  box that slid along two sled type runners.  Dimen-
 sions of  each part are given along with details of the workings and
 operation of  the trencher and its parts.  Loading of spoils to trucks
 is  described.   Two guidance systems are mentioned; one which used a
 survey string line,  and the other which employed an Acme laser gun.

Identifiers:  *Mole, Laser beam.

This article  explores advances made since 1963 in equipment used by con-
tractors in non-highway  construction.  Means  for handling, lifting, and
moving materials  grew steadily in size and power.  Conventional-type
equipment—cranes,  derricks,  conveyors, and pumps, became taller, strong-
er, and more  versatile.   Earth and rock boring for tunnel construction
became easier with  the development of machines able to tackle any type
of geological formation.  Special rigs are described which place large-
diameter piping inside long tunnels.  Advances in mole tunneling are
cited.  Hydraulic pumps,  driven by electric motors, provide rotation,
twist, and  up-and-down actions of the boom and bucket, and they also
propel the  machine.  Construction crews use laser beams as constant
reference lines.  They are visible day and night for long distances and
are weak enough to  be harmless.  Future tunneling may be accomplished by
rapid melting of  rock with lasers or electron beams.  New innovations
discussed include:  hydraulic-boom cranes, hydraulic fork lifts to
handle heavy  wall and slab forms, lightweight plastic-foam materials,
concrete pumps, electronic computers, and television.

 Descriptors:   *Flood  damage,  *Culverts, *Cranes, *Repairing, *Construc-
 tion,  *Installation.

 When a 500-foot length  of culvert comprised of 600 plate sections was
 washed out  by  a flash flood,  the contractor unbolted the conduit in 36-
 foot barrels instead  of dismantling the pipe plate by plate and lifted
 the sections out  by crane.  The sections were stored on the bank to be
 reset  after the bed dried and was restored.  A simple wooden screed
 shaped the  concrete sand  bed  for the 21-foot diameter culvert.  Details
 of the construction and installation procedures are included.

Identifiers:   *Canada, *Interceptor sewer, Toronto.

In metropolitan Toronto an interceptor to relieve existing high-  and  low-
level  interceptor sewers, which are inadequate for the area they  cover,
is under  construction.  S. McNally and Sons Ltd. was among a number of
bidders,  and  it was awarded all portions of the project.  The project
entails the construction of a 61,640 foot-long shaft varying in diameter
from 60 to 120 inches spanning the city from east to west.  The estimated
time of construction is three years.  Information on the operation and
techniques used is included.

Identifiers:  *Germany, *Fusion welding.

In Germany, plastic pipes with up to 40-inch diameters and pieced in 500
to 1,000 foot sections are common engineering equipment.  These poly-
ethylene pipes cost slightly more than other types of pipes; however,
installation costs are drastically lower, especially when used in long
runs.   The butt-fusion welding practice is quite routine in Europe.
This process of  installation is described.

 The FWPCA is  financing projects to  install  rubber stormwater storage
 bags at three locations:   Washington's Anacostia  River,  Sandusky,  Ohio
 at Lake Erie, and Cambridge, Md.'s  Choptank River estuary.   The bags
 will store stormwater overflow that normally flows untreated into  rivers
 and lakes along with sanitary sewage, when  flows  exceed  treatment  plants'
 capacities during heavy rainfall.   The Washington bags  rest  on the
 bottom of the Anacostia River offshore of  the pumping plant.   The  plant
 will chop overflow solids before the water  reaches the bags,  and an
 aerator will suspend the solids.  The solids come out with the stored
 water when it is pumped back into the sewers for  treatment.   These plans
 are considerably less costly than sewer  separation which would cost  an
 estimated $48 billion to accomplish throughout the United States.

Two large 100,000 gallon  tanks of nylon-impregnated rubber have been
anchored in metal cradles on the bottom of  the  Anacostia River.  During
rainfall the tanks are used to hold overflow and later, when the water
has receded, the  tanks are emptied and  their contents pumped easily to
the sewage  treatment plant.  These tanks have also been used for holding
fuel, water, oil, beer, and wine.

A description is given of the installation  of inflatable bags of rubber-
ized fabric at the outlet points of the storm-sewage overflows serving
Minneapolis and St. Paul, Minn.   The bags,  which were installed to re-
duce pollution of the Mississippi River during storms, can be inflated
by remote control to provide dams varying in height, thereby at any time
diverting as much storm sewage into the interceptor sewers as the treat-
ment works can accept.

By using Armco Steel Corporation's double-walled Truss pipe, a ground-
water infiltration problem was eliminated from Galveston's sewer system.
The Truss pipe can also be easily tapped for house connections, and its
low infiltration specifications make possible an economical design for
factory-built treatment plants.  Construction costs for such plants are
included, as well as dimensions of the extra-strength piping.

CONSTRUCTION  COST  REQUIREMENTS FOR WATER AND WASTEWATER FACILITIES,
Public Works, Vol  98, No  12, pp 112-113, Dec 1967.

Descriptors:  *Cost  analysis, Waste water treatment.
Identifiers:  *Wastewater facilities.

The Business Defense Services Administration surveyed 1200 major water
utilities  in order to predict the construction cost requirements for
water and  wastewater facilities.  The forecasted average annual expen-
diture over the  14-year period  (1967-1980) showed a 139% increase over
annual amounts for the past 12 years.  These expenses result from the
need to  remedy present defects, to account for depreciation and obso-
lescence,  and to counter  the demands of an increasing population.  Data
included indicating  costs required for various types of water supply and
wastewater utilities in addition to amounts to be spent to combat indi-
vidual problems  can  serve to guide manufacturers in planning future con-
struction.

A new square-line instead of round rainwater gutter system of plastic
was displayed, in addition to a squareflow rainwater gage.   Both have
greater flow capacity than their traditional counterparts.   A new drain-
age system exhibited has the following features:   simplicity of  layout
and specification, push jointing of pipes, fittings, and  plumbing con-
nections, and fast laying speed.  A domestic underground  stormwater
drain using plastic Polydrain PVC pipe was demonstrated;  this material
is now being employed extensively for underground drainage systems.

 Doncaster  sewers were  improved once in 1956, but in 1966 a major recon-
 struction  of the pipes was necessitated due to corrosion by sulfuric
 acid produced  by bacterial action.  Adjacent to the old sewer, the new
 sewer was  constructed  in  the material most resistant and readily avail-
 able, namely,  bitumen-coated asbestos-cement.  Procedures followed for
 construction and installation of the pipes is described.

 Exhibition were Metrex sewage and  drainage and rigid  PVC  rainwater  sys-
 tems, a large range of PVC  pressure pipe,  examples  of asbestos-cement
 pressure pipes, Polydrain PVC underground  drainage  systems,  and plastic
 pipes.  The PVC pressure pipes had a push  type Z joint with  a lip rubber
 seal.  This joint, which is easy and quick to assemble, had  been made
 practicable for pressure mains of  large diameters up  to 18 inches.   The
 asbestos-cement pipe display showed not only new pipes but also old,
 well-preserved pipe that had lain  in the soil for many years.  One  ex-
 hibit demonstrated the economy gained in cost, labor, weight, and main-
 tenance when using plastic  pipes and systems.

The use of flexible rubber containers for off-shore underwater temporary
storage of storm overflow from a combined sewer has been proposed for the
Sandusky Bay area as the answer to its storm overflow problems.   The con-
tainers are predicted to temporarily hold overflows equivalent to a one-
year storm.  When the plant can handle the excess, the contents  of the
containers are pumped back to the plant where the sewage is treated and
piped into the bay.

essentials will be provided:  (1) strength, (2)  positive couplings,
(3) long service life, (4) unchanging hydraulic properties, (5) versatile
fittings, and (6) proved materials.   Each of these factors is demon-
strated in corrugated steel pipe storm sewers.  Product details are dis-
cussed, including sizes and details  of the pipe and pipe-arch; couplers
and fittings; and bituminous protective coatings.  Technical data ex-
plained include:  hydraulics and the determination of size, Manning
charts, structural design, the height of cover tables, and service life
design.  Also described are techniques for installation and specifica-

 A pilot  plant was  designed, constructed and operated to assess the
 feasibility of providing a  facility for the collection, treatment,
 storage  and final  disposition of a portion of the storm overflow from
 a combined  sewer system  serving a thirty-acre drainage area in Washing-
 ton, D.C.   A  Parshall  flume was installed in the overflow line for
 measurement of flow  rates and determination of total overflow volume.
 A portion of  the overflow was diverted to the pilot plant through grit
 chambers and  a comminutor.  Flow was stored in two 100,000-gallon under-
 water bags  fabricated  of nylon reinforced synthetic rubber and fastened
 to the river  bed by  a  system  of patented anchors.  During the period of
 storage, compressed  air  was delivered to the tanks for agitation of the
                                  15

-------
solids.  Following cessation of the storm, contents of the bags were
pumped to the interceptor sewer for delivery to the District of Columbia
Sewage Treatment Plant at Blue Plains.   Flow into and out of each under-
water storage tank was metered and recorded.   Samples of the combined
sewage overflow discharged to the bags  and pumped discharge from the
bags were collected and subjected to laboratory analyses.  During the
operation period from January through September,  1969, a total of
1,600,000-gallons of diverted overflow  from 38-storms was stored in the
tanks.  In addition, 600,000-gallons of river water was pumped into the
underwater storage tanks for testing during dry weather periods.   The
total amount stored was pumped to the interceptor sewer in 26-separate
pump out periods.  The cost of the pilot plant was $341,480.00, or
$1.70 per gallon of storage.   This included facilities for testing,
samples and flow measurement.   Estimates for  larger installations,
without these special requirements range from 28.2 cents to 14.6  cents
per gallon for plants with storage from two to twenty million gallons.
The project demonstrated that temporary storage of overflow from com-
bined sewers in underwater rubber storage  tanks is feasible and may,
under suitable conditions, be effective in eliminating direct,  untreated
discharge of combined sewage into surface  waters  during storm periods.

The objective of this program was to develop new, more effective sealants
for sewer line leaks.  This purpose was achieved, and all equipments  and
materials investigated, tested, or compared are presented, along with
test results, supporting data, conclusions, and recommendations.  Candi-
date materials were surveyed and weaknesses of rejected materials were
noted.  Specific properties of acceptable materials were ascertained, and
materials having these properties were  identified and subjected to  tests
designed to demonstrate their effectiveness as sealants.  It was con-
cluded that infiltration adversely influences sewer system operating
costs and effectiveness, and that leakage repair  systems are limited  in
their effectiveness.  No significant cost increase beyond that experienced
with present sealers was indicated.  Some present sealant application

The author describes several sewer jobs he undertook as a Resident
Engineer in the Glasgow Office of Public Works.  One job entailed the
construction of a two-mile main duplicate sewer in Rutherglen.  Problems
arising due to encounters with varying types of ground are related and
measures taken explained.  As a result of high pressure, escapes of air
(blow-outs) occurred on a nearby railway line.  Tunneling was halted
until a tunnel shield was installed which helped complete the job.
Other construction problems relating to sewer jobs are discussed.  In-
terference with Glasgow parking areas due to sewer construction was
solved through the institution of a program of conversion of open
spaces to off-street car parks.  In conclusion, the author recommends
the establishment of regional sewerage authorities similar in organiza-
tion to Scotland's Water Board, plus the formation of drainage bound-
aries on a topographical.rather than a parochial basis.

District of Columbia area engineers and the USCA Soil Conservation
Service jointly worked to improve sediment basin design.  These basins
prevent damages originating from soils disturbed by intensive construc-
tion.  Their purpose, is to trap eroding soil and keep it on or near its
original site while earth-movers do grading for new developments.   These
structures are temporary, but they protect stream-channels, impound-
ments, roads, etc. from damaging sediment.  A typical sediment basin
holds ponded runoff from which soil particles settle as water passes
slowly into a vertical drain shortly after a heavy rain.  Details  regar-
ding construction and performance are discussed.  The fundamental  de-
sign problem of striking a balance between detention time and economical
basin size is also explored.  Effectiveness of these basins is proven by
the increasing number of counties employing the structures in the
metropolitan Washington and Baltimore areas.

Drainage lines, which  can be sanitary, storm or combined sewers, should
be well designed and constructed,  properly supervised during construc-

to facilitate compliance with  these objectives.  Sewer installation is
described in terms of  considerations to  be made regarding the filled

to the selection of the least  expensive  materials  because cheaper ma-
terial may prove to be the most expensive  to the taxpayer in the long
run.   Infiltration and joint failure are treated briefly with recommen-

and more than $2 billion for city-wide  installation.   In  Washington,
large rubber tanks will be anchored beneath  the surface of the Anacostia.
Stormwater and sewage overflow  will be  diverted to these  tanks and stored
there until  the water has receded,  and  the tanks'  contents can be pumped
to the nearby sewage treatment  plant.

The  installation of a computer-augmented treatment  and disposal  (CATAD)
system to  utilize optimum storage within an  existing municipal  combined
sewer  system was described.   The other objectives of CATAD were:   (1) to
make available  the maximum capacity  of the interceptor for combined
storm  and sanitary flows  in unseparated  areas by utilizing the  storage
capability of  trunk and interceptor  sewers in separated  areas;  and  (2) to
control necessary overflows  at  selected  locations so as  to minimize harm-
ful  effects  on  marine life and  public beaches.  Control  commands were
generated internally by a computer  under program control.  A mathematical
model  was  developed in order to implement a  fully automatic control.  The
model  incorporated elements  of  meteorology  and hydrology  including sea-
sonal  precipitation patterns and area runoff characteristics.  An  analysis
of the regulation of stormwater inflows by the use  of trunk sewer  storage
established the operating rules required for effective utilization of the
available  storage.

J Water Works  Assoc, Vol 84, No 2,  pp 127-151, Jun  1970.

Descriptors:  *Flowmeters, *Discharge measurement,  *Hydraulics,  Instru-
mentation, Testing.

A variety  of discharge measurement  devices have been invented of which
a flow measuring system using the LE Flowmeter is the most recent  system
to substantially advance  the art.  The concept employed  is an application
of numerical integration  by  Gaussian Quadrature.  Test results  under
                                  23

-------
varying conditions of fully developed and distorted flow show that  this
measurement system has an rms accuracy better than 1.0 percent.  Use of
the LE Acoustic Flowmeter gives this flow measuring system features not
possessed by other devices, such as linearity, bidirectionality, no head
loss, and no need for calibration.

Descriptors:  Instrumentation, ^Monitoring, *Water quality.
Identifiers:  *Water quality monitor.

Beckman Instruments, Inc.  offers a multi-parameter Water Quality Monitor
for  continuous measurement of:  disolved oxygen, temperature, pH,  chlo-
ride ion, turbidity, oxidation-reduction potential, sunlight radiation
intensity and conductivity.  The new instrument features sensors which
improve reliability of continuous monitoring while reducing maintenance
requirements.  This instrument is compatible with conventional forms of
transmission and data handling.  Pollutants in water such as silt,  slimes,
soluble and suspended solids, and algae coat and contaminate sensing
elements.  This paper explains Beckman's approach to this problem  of
continuous water quality monitoring.

Descriptors:  *Testing, *Sewers, *Infiltration, Leakage.
Identifiers:  *Sewer lines, *Air-testing.

New wastewater lines  can be tested for leakage or exfiltration either
by the common  method of water pressure or by  low-pressure air, a method
becoming more  popular.  Such  testing is  imperative since  if  there is no
exfiltration,  neither will there be infiltration.   A tight sewer line
lowers the volume flowing into lines and treatment plants., thus, pumping
and treatment  costs are lowered, and less  flooding occurs.  The author
presents eight frequently-asked questions  concerning air  testing, and he
answers the questions briefly.

the waste return piping system.  Dimensions and descriptions of the
three pipe types are given, and installation methods are also discussed.
Alternate materials investigated and rejected were:  cement-lined steel,
cement-lined cast iron, asbestos cement, plastic protected metal (IPM),
reinforced concrete, glass or glass-lined pipe, uncoated steel or cast

Identifiers:  *Sanitary sewers.

G. L. Marsden-Jones:  With reference to the article, "Sewers Under
Attack"  (9 January), he questions whether or not  the use of bitumen-
coated asbestos pipe implied that concrete could  not be used for sani-
tary sewers.  He  also wonders  if gravel used to surround pipes produces
a drainage effect that harms farm land where groundwater is short in
supply and, at sewage works, raises groundwater level causing floods.
J. A.  Foster:  In reply to this first question, he notes that only the
specific  circumstances at  Doncaster warranted use of bitumen asbestos-
cement pipes and  that  for  most sanitary sewers, concrete is a suitable
material.  He further  explains reasons  for Doncaster's use of the unu-
sual material.  In  answer  to the second point, he states that normal
practice  in waterlogged ground is to supply impervious clay cut-off
 walls at proper intervals to prevent groundwater movement along pipe-
 lines .

Identifiers:  *Pipe materials.

Although  the use of calcareous  aggregate in the manufacture of concrete
pipe  for  sewers  has been advocated for those situations where there is
a hazard  of mild sulfide conditions,  there is  a lack of data comparing
this material with  others.   Tests on  five  8-inch diameter pipes handling
septic wastewater were  run for  a period of seven years.  Results show
that  the  rate of corrosion was  inversely proportional  to the alkalinity
of the pipe materials.  The  pipe with composition of type II cement plus
limestone aggregate had a  rate  of corrosion approximately one-third as
great as  the average of the  others made without limestone aggregate.

an hydraulic mast, and an adjustable crumbing shoe.  Minor modifications
include:  converting the mechanical drive train from a 21- to a 42-tooth
sprocket to increase torque on the cutting wheel, reinforcing the idler
axle, and replacing an 8"foot Jetco arc-type conveyor with the Parsons
original.  The trencher not only cut through flinty rock, but it kept
well ahead of rigs forming the cast-in-place drain.

 Existing methods of measuring discharge of sewers  are discussed with
 respect to the requirements and physical limitations imposed  by their
 use in an urban study  area, and rating curves  for  a suggested critical
 flow device are presented with recommendations for future  research.   The
 gage must have an output in the form of an electrical signal  for record-
 ing, be automatically  turned  on and off, and need  no attendant.   Labora-
 tory velocity  probes are unsuitable because of clogging problems.  De-
 sired accuracy is  5% in  discharge measurement  over a large flow range.
 The device must be capable of installation in  any  existing sewer at
 reasonable cost.   Weirs, depth gages, and  velocity meters, the  methods
 presently available, all have serious disadvantages and are not recom-
 mended.   Tracer dilution methods as well as Venturi flumes and  other
 critical flow  devices  are suggested for development,  A pipe  section
 with a narrow  throat acts as  a Venturi flume for open flow and  as a
 Venturi meter  for  full flow.  Plans and theoretical rating curves for
 such a device  are  shown.

 Descriptors:   *Instrumentation,  *Waste treatment,  ^Control systems,

 As waste treatment and recovery  processes become more complex and  costly,
 there is increasing reliance upon instrumentation  to  assume  control res-
 ponsibility for the most economic and efficient  operation.   This paper
 describes the control systems normally used on four applications,  and
 discusses what can be done to optimize performance.   The  use of dissolved
 oxygen  and sludge density measurement in the  activated  sludge process is
 explored.  The second application is pH neutralization.   Feedforward
 control and the nonlinear controller have  dramatically  improved neutrali-
 zation  performance.  Improvements are also  suggested  in the  control
 schemes of chromate waste and cyanide waste treatment processes.

This subsection discusses existing processes,  recent advances, and
current problems relating to municipal wastewater treatment.  Urban
stormwater problems from combined sewer overflows are explained, and
possible solutions presented, such as storing  overflow and then passing
it to plants for skimming and sedimentation and/or polymeric floccula-
tion treatment.  Other means of handling overflows include storage in
fully or partially flexible underwater tanks or in underground tunnels
with subsequent treatment, chlorination, and filtration aided by ultra-
sonic energy.  One current project is evaluating the use of 1-2-acre
ponds to collect stormwater runoff and then treat it for reuse.  The
following recommendations in the area of municipal wastewater treatment
were made:  (1) more research by biochemists and biologists on sewage
treatment, primarily to seek radical innovations based on fundamentals
of microbiological processes; (2) research expansion on new methods of
handling wastewater treatment sludges and on parameters involved in
using synthetic polymers and polyelectrolytes  to improve flocculation,
sedimentation, and conditioning of such sludges;  and (3)  more systematic
studies on urban stormwater quality to provide a sounder base for
evaluating various means of treatment.

 Stuides were performed in three  areas  served by combined sewerage
 systems on the  amount, composition,  and  pollution  load of stormwater
 overflows.  There was  regularity in the  volume  of  storm sewage at the
 three sites in  relation to  impermeable area, total rainfall, and dry-
 weather flow; however, no regularity was detected  in  composition.
 Generalizations were made regarding runoff, sewage dilution, single
 storm discharges, etc., and specifics  for each  locale were also described.
 Recommendations were made for  the placement of  storage tanks alongside
 of  storm overflows  and for  experimentation in designing different types
 of  overflows  in order  to reduce  pollution load  discharges.

 A generic Fluidic Regulator  configuration was developed which  diverts 0
 to 75% of the combined sewer  flow away from  the interceptor  sewer,  or
 combined  sewer,  in  either an  analog or digital operational mode.   Appli-
 cation design criteria were  evolved for a range of small  to  medium sized
 municipal sewers, in terms  of  a few basic parameters.  Preliminary
 analysis  has  shown  that the  installation  of  a combined sewer fluidic
 regulator is  similar in nature and overall complexity to  a conventional
 leaping weir, or  side flow  diversion  structure.  It  is estimated that
 the use of  a  fluidic regulator would  not  increase the cost of  a large
 diversion structure,  and  would add about  20% to the  cost  of  a  small
 diversion structure.   A simulated fouling test showed a very low sus-
 ceptibility  to  fouling by solid or soft sheet-like debris in the water
 flow.

This study was conducted to evaluate the feasibility of a self-adjusting
and self-cleaning  filter proposed for use on combined sewer systems to
remove a  large portion of suspended solids from sewage influent during
storm flow  conditions.  The experimental filters were cylindrical
structures  about one  foot in  diameter by one foot in length and whose
materials of  construction were fibers laid down in predetermined patterns
by a winding  process  and bonded in place by resins.  The permeability of
the structure is imparted by  a mechanical crazing of the resin.  Filtra-
tion runs showed a 62% reduction of suspended solids in the filtrate;
however,  sustained runs  could not be realized.  The self-cleaning
capability  was not demonstrated.

In a pilot installation at the terminus of an existing urban overflow
location, a rapid-flow filter using lump coal as the filter medium per-
formed with a minimum of maintenance or difficulty.  The preferred
filter used lump coal with a size of approximately 3/4 inch by lh inch,
free of fines, and about 8 inches in depth.   The overflow is directed
onto the filter bed in such a manner that the filter bed is not
displaced.  Filter bed depth did not appear to be critical; the degree
of solids removal does not materially increase at depths exceeding 8
inches.  Because the concept is based on the use of a disposable filter
medium, no backwashing or other processing is required.  It appears that
replacement approximately 6 times per year might be expected as an
average.  At no time during this investigation was an odor of sewage
solids or garbage detected as long as unoiled coal was used and the
filter was shaded from the sun.

A dissolved-air flotation system was evaluated for primary  treatment  of
combined sewer overflows.  The major pieces  of component equipment were
a gyratory screen, hydrocyclones,  an air  dissolving  tank, and a flota-
tion cell.  The principal aspects  investigated were:   (1) performance
of the system during rain events and dry  periods;  (2)  evaluation of
individual components; (3)  capital costs  and operating  costs  for utiliz-
ing a flotation system for various size combined  sewage overflows;  (4)
the adaptability of the system for automation and use  in remote location;
and (5) the ability of the system  to treat intermittent and highly
variable flows from combined sewage systems.   Some chemical aids to
flocculation were also tested.   It appears that  dissolved-air flotation
systems would be economical for handling  combined sewer overflows  up  to
8 MGD.  Automation of dissolved-air flotation systems  appears  possible
with conventional control equipment.   Chemical aids  to  flocculation
seem to have promise that warrants  further study.   The  system was  unique
in that all liquid flow passed  directly through  the  air dissolving tank
with no recycle.  Domestic  sewage  was  studied in  lieu  of  combined  sewage
during periods of no rain.   Conclusions,  recommendations, and benefit-
cost relationships are presented in the report.   A description of  the
demonstration plant and the drainage area served  by  the flotation  system
are appended.

the combined overflow from many small storms at a cost of slightly over
$2 million.  The system includes telemetering rain gages, sewer level
sensors, overflow detectors, a centrally located computer and data-
logger, and a centrally located operating console for controlling
pumping stations and selected regulating gates.  Installation has been
virtually completed and now enables applying such pollution control
techniques as storm flow anticipation, first flush interception, selec-
tive retention, and selective overflowing.

The principal of  a "self-cleaning strainer, self-cleaning  filter" concept
for the  treatment of  combined  sewer  overflows was evaluated  in this
feasibility  study.  The strainer and filter systems were examined using
a synthetic  substrate (prepared on the basis  of  overflow sample analysis
data obtained from analysis  of a combined sewer  overflow in  Providence,
Rhode Island),  primary  influent to two separate  municipal  treatment
plants,  fresh sewage  solids, and  combined sewer  flow.  It  was demon-
strated  that the  strainer model produced consistent suspended solids
removal  rates near 35%  under highly  varying load conditions, at a flux
of 25 galions/minute/sq.  ft.  The authors believe that  a strainer-filter
system of the type originally  envisioned is not  feasible from a cost and
operational  point of  view if additional  treatment is  necessary beyond
that attainable with  a  self-cleaning strainer.

the provision of regional storm sewage balancing stations was initiated.
Excess flow would be diverted to tanks at the stations until available
capacity  could be made in the sewer downstream and pumps then would
automatically return the contents of the tanks.  In the reply to the
discussion following the article the limits for discharges from the

 Conclusions  of the Final Report of the Technical Committee on Storm

 The major outcome of the report proposes a formula for the setting of
 storm overflows which replaces the former method of fixing the setting
 at 6 d.w.f.  Features and advantages of the formula are given.  Sewer
 separation was considered but eventually rejected by the committee
 because  of the huge cost involved and the inevitable pollution from sur-
 face water drains of separate sewers.  Other areas studied were the
 effects  of storm sewage on rivers and the composition and strength of
 storm sewage.

 the  area with one large dry well absorbing overflow from the smaller
 ones.   This system  was adopted  because storm sewers were not available
 in the region. Only minor flooding occurred once when there was a heavy
 rainfall,  so  the  effectiveness  of this system was evidenced.

In order to find methods for controlling or treating storm-sewage over-
flows from combined systems in urban areas, overflows from the combined
sewerage system of San Francisco were measured and sampled for analysis
at two outfalls in the city.  The dry-weather flows were also monitored.
From the data obtained and other observations, the annual runoff for the
whole of the city was compared with its total annual discharge of treated
sewage effluent, and the effects of the dry-weather flow on the overflow
and of the overflow on receiving waters were investigated.  The latter
effect produced a considerable increase in the numbers of coliform
bacteria which remained higher than normal for about two weeks.  The
studies showed that treatment of overflows from combined systems could
result in a substantial reduction of pollution at less expense than
would be involved in separating the systems, and that dissolved - air
flotation with chlorination appeared to be a promising method.

For determining the capacity of the sewer system including stormwater
drainage in Hamburg, the flow speed, the water level, and the  sludge
deposition during dry weather were measured.  The speed is found to be
approximately 0.5m/sec, and sludge deposition is hardly avoidable at the
low inclination of the canal system.  The conditions during rainy
weather were determined with automatic level recording units.   From
these level? measurements the frequency of overflow in days/year, the
overflow duration in hours/year, and the overflow quantity/year were
calculated.  From the recordings of rainfall and the level measurements
at the overflow spills of the sewer system a diagram is drawn  according
to Kuipers' equation providing information on the storage capacity and
discharge capacity of the overflow spills.  These two parameters deter-
mine the critical rainfall for the overflow spill.   Its magnitude
decreases with increasing duration of rain and asymptotically  approaches
the discharge capacity.  To avoid frequent overflow, calculations should
be based on the critical rainfall as a function of the overflow time.
Since this is not practical, it is recommended to use the normal rainfall
for the calculation and multiply the quantities obtained by a  constant
factor.

 Where sewage works treat flow from catchments which are served by  com-
 bined or partially-separate sewers, a moderately intense railfall-runoff
 rate will necessitate passage or storm-tank storage of excess flow.   The
 Royal Commission on Sewage Disposal makes recommendations regarding  the
 handling of such overflows.  The author of this paper disputes their
 statement that storm tanks able to hold one-quarter of the daily dry-
 weather flow will suffice for storing spill-over from small storms.   He
 notes that a capacity of two days dry-weather flow is often needed to
 prevent spill-over occurring.  Functions of storm tanks and the mathema-
 tics of stormwater treatment are described.  A suggested design for tanks
 consists of circular tanks  with  ratating sludge mechanisms.   A formula
 for calculating the required capacity of a tank to  prevent spill-over
 is included.

Metro has devised various solutions to underground construction problems

include the removal of digested sludge from Puget Sound and the elimina-
tion of combined sewer overflows.  Sewer separation is not presently
feasible because of the expense, so the Metro interceptor system is
being ordered to run the entire system.  In the meantime, money originally
reserved for storm water holding tanks is being contributed to the city's
proposed sewer separation system.  Metro is continuing its innovative
engineering programs and is  coordinating its activities with community

A description of the structure and an assessment of  the 5-year  operating
success of the Crossness Sewage treatment plant are  discussed.  All flow
which once passed to the river must now be pumped through the plant,  even
wastewater gravitating in storm tanks oribinally used as  reservoirs.
Moderate storms occurring after two or three weeks of dry weather  create
flows which exceed the capacity of the screening gear when old  combined
sewerage systems are in use.  In the "Discussion," H. H.  Stanbridge
asked how the plant operates under maximum flow in comparison to average
flow.  The authors replied that maximum flow was 216 mil  gal and  that
flows exceeding this level passed to storm tanks. Most of this excess
(3.2% of the total flow in 1968-9)  was later returned for treatment,  but
19% of this load was discharged to the river.  Tables and graphs  describ-
ing the 5-year operation of the plant include:   the  effect of rainfall
on suspended solid load, syspended solid load per day,  main pumping
station statistics, and the performance of primary sedimentation  tanks,

"Overland flow' over natural surfaces is unsteady and spatially varied,
due to both rainfall and infiltration.  Most experimental work to date
has been done using impermeable surfaces, the effects of time-dependent
infiltration being ignored.  Research into flows over natural surfaces
is time consuming and the results are difficult to interpret at this
stage in our knowledge of such flows.  A method of simulating infiltra-
tion is described which enables experimental work to be undertaken in a
tilting flume.  The system produces a time-dependent decay in simulated
infiltration, and can be described by an equation of the form used by
Kostiakov.  Since the two parameters involved can be readily altered, the
system provides a means of simulating a range of field surfaces.   Some
initial results using the method are described.

Three alternative plans, proposed locally  as  solutions to flood control
and pollution problems in the Chicago metropolitan area, are described
and compared.  The combined sewer systems, which carry the municipal and
industrial wastes as well as storm water runoff, spill raw sewage into
the Des Plaines, Chicago and Calumet  Rivers, and the Sanitary and Ship
Canal from 400 outlets, during  overflows occuring when interceptor
sewers and treatment plants are loaded beyond capacity.  The flow from
these rivers empty via the Des  Plaines River  into the Illinois River.
Intense rainstorms frequently result  in basement and  underpass flooding.
The $650 million plan suggested by the City proposes  the construction of
95 miles of huge conveyance tunnels,  26 ft wide and 50 ft deep, excavated
through solid rock beneath the  Chicago, Calumet, and  Des Plaines Rivers,
and the Sanitary and Ship Canal.   Flows from  the combined sewers would
be dropped through shafts into  these  tunnels  to provide temporary
storage for flood prevention and to collect sewer overflows  for subse-

This paper deals with  the  relation between the critical rainfall and
runoff  and the  resulting dilution.  Investigating the  effect of the
fundamental  lay-out of storm sewage overflows, the author  concludes that
if two  storm sewage overflows are  constructed  at a given position in
place of one,  the  polluting  load discharged to the receiving water can
be greatly reduced.

 Descriptors:  Concrete construction, Drainage  programs, Storm runoff.
 Identifiers:  Street drainage.

 A far-reaching street-paving program  was  implemented in Albion, Nebraska
 after heavy rains caused driveway culverts  to overflow, ditchwater to
 stagnate,  and runoff to spill  into streets  and parkways because ditches
 were clogged.   Concrete curbs, gutters, and pavements were installed to
 ameliorate this situation and  also to provide dust  control.  The entire
 project cost  $473,619.48 (about $5700 per block).

Identifiers:  *Stormwater control.

State College, Pa.  constructed a  reservoir to contain runoff until after
a storm, instead of installing a  more costly water-carrying conduit.  An
electrically controlled gate closes when rain causes the water level in
the reservoir to rise,  and it opens when the storm subsides, thus,
allowing the rainwater  to drain.   As a part of State College's sewage
project, a new storm trunk line was built contrary to common practice;
that is, from the center of the job downstream,  to reduce the threat of
the pipe coming afloat  in the event of a flash flood.  This plan was also
successful; flood water was forced inside the pipe rather than flowing
around the outside and  causing flotation.  State College also formed a
Storm Water Authority to undertake the financing of such storm water
control projects.

Storage tanks and reservoirs should provide for flow  equalizing, fire

necessary to determine the most economical  combination of  storage faci-
lity, trunk mains, and pumping facility- Criteria for locations of
storage facilities and construction cost considerations are noted in
this article.  Stormwater systems  exhaust sizable  segments of expenditures
utilized for water storage in general.   Drains must provide for normal
stormwater runoff and higher flows resulting from  reservoir emptying and
inadvertent overflows.

water overflow to pass to the river, was completely filled with silt as
were other parts of the sewage disposal system.  In addition to repairs
on the sewer disposal and sewerage systems, town workers cleared the
outfall pipe, thus, establishing a bypass to the river.  They then con-
nected the washout valve on the filter feedline near the dosing chamber
to the humus tanks.  By re-opening the inlet valve to the primary sedi-
mentation tank and opening the dosing chamber's washout, primary tank
effluent was routed to the humus tanks; and thus, a two-stage settlement
treatment system was instituted in place of discharging raw sewage over
the side weir storm overflow.

cusses the use of oil  separators for areas where  large volumes  of oil
are handled and where  spillage is  washed off into the receiving water by

likely to be affected  before storm sewage  enters  the receiving  waters.
Standards for the design of such separators  are discussed.

A feasibility study was conducted for the FWPCA of a proposed offshore
stabilization-retention basin, for the treatment of various polluting
flows now  being discharged to Lake Erie.  The basin would receive
treated  effluent  flow from the City's Easterly Wastewater Treatment
Plant, as well as flow from six large combined sewer overflow outfalls
and  flow from five polluted streams which drain the service area.  The
proposed basin would be approximately 900 acres in area, with a mean
water depth of 33.5 ft.  A shoreline collection system is included to
convey flows to two central points for discharge into the basin.  The
collection system will consist of a combination of gravity and pressure
conduits, with two pumping  stations.  Two  basic types of purification
processes will take place in the basin.  Biological and chemical oxida-

tion will result in reduction of BOD and COD; this process  will require
an aerobic environment.  Sedimentation of fine suspended solids,  particu-
larly the activated sludge cell matter in the treatment plant effluent,
will require quiescent settling.  To meet these two conditions, a two
stage basin is contemplated.  The first stage will be maintained in
aerobic condition by air-lift or mechanical pumping.  In the quiescent
sedimentation stage, it is expected that an upper layer of  five to ten
feet of water will be aerobic, with the remainder of the depth anaerobic.
The basin will create a sheltered bay at the shoreline, which will be
used for boating, fishing and swimming.  A small boat marina is contem-
plated as part of the overall project.  The basin will be provided with
facilities for chlorination.  Effluent will be discharged at about 8,000
ft. from shore in a water depth of approximately 42 ft.  The basin has
been found feasible from the standpoint of pollution abatement and
reduction of bacterial contamination of the City's beaches  resulting
from polluted discharges.

Descriptors: ^Pollution  abatement, *Application methods, ^Separation

Identifiers: Combined sewers.

The drawbacks of separation include high costs, public inconvenience
during  construction, and the  continuing problem of polluted stormwater
runoff.  Alternative solutions  to this pollution problem either reduce
pollutants  in the overflow or decrease amounts of combined sewage that
is overflowed.   Pollutants can  be eliminated from overflows through
storage and treatment methods such as disinfection, screening, sedimen-
tation,  filtration, and  other overflow devices.  Possible procedures
for diminishing  combined sewage overflows outlined include real-time
control of  discharge points, storage by use of larger pipes, or increased
interceptor and  treatment plant capacity.  Each locality's  circumstances
will determine which method or  combination of methods will provide the
best means  for solving its pollution problem.

The equipment examined for dealing with storm-sewage overflows  in
sewerage and other  drainage  systems comprises  a  bay fitted with a trough
or channel which has walls of  unequal  height and a mouth covered with a
filter screen,  which can be  cleaned by a rake  or rakes  rotating in the
direction of  flow of water through the bay.  Under normal conditions  of
flow,  water passes  through the bay directly to the sewer,  but under
storm  conditions, the increased  flow causes a build-up  of pressure in the
bay so that water and floating trash flows over  the lower wall  of the
trough and through  the screen  to  the storm-sewage  outlet.   Trash is
swept  from the  screen by the rake(s) over the higher wall into  a trash
pit and thence  to the sewer.

thought of tilting a horizontal sewer line to a 90 degree position,
thus changing the flow characteristics.  The design of the pipe has
been worked out so that all dimensions are a function of the inside
diameter, and the design can be adopted to any size of pipe.  The
installation procedure and the estimated cost of the new line are

upon aquatic flora and fauna, flow characteristics of wastewater, and
the operation of a wastewater treatment plant.  It was found that the
polymers and gels, in the magnitudes tested, were not toxic to bacteria,
algae, or fish, and did not act as a nutrient for algae growth.  Based
upon calculations obtained from flow test data, a maximum flow increase
of 2.4 times the flow prior to injection could be obtained if a constant
head was maintained.  Laboratory flow test data indicated that if flow
rates were held almost constant prior to and during polymer injection,
a reduction in the static head occurred as a result of friction reduc-
tion within the fluid.  The most effective polymers in providing energy
reduction were Polyox Coagulant-701, WSR-301, and AP-30; however, AP-30
required higher polymer concentration to obtain equivalent flow charac-
teristics.  In field tests on a 24-inch diameter line, it was found that
polymer concentrations of between 35 and 100 mg/1, decreased frictional
flow resistance sufficiently to eliminate surcharges of more than six
feet.  Based upon an economic analysis, the average annual cost of new
construction was approximately five times the cost of using polymers
during peak storm-flow periods.

Identifiers:  *Surface runoff, Groundwater, Belgium.

The stages followed in designing a subsurface drainage system for the
inner-ring road being  built in Antwerp,  Belgium are described.  The
system will collect and carry away surface runoff, will permanently
lower the groundwater  table*, and will collect and carry away seepage
water resulting from this lowering.   Conventional methods were adopted
for stormwater drainage design.   The seepage water and stormwater col-
lected in a catch basin will run by gravity in pipes to one of four
low points in the road's vertical profile.  From two of these points
the water will flow to pumping stations  and from the other two, into
rivers.  The most complicating factor in the subsurface drainage
design was the possible effect of the precipitation of ferric oxide
from groundwater.  This factor necessitated complete submergence of
the intake system.  Factors influencing  the final selection of the
subsurface drainage system are explored  in detail.

Discharges can be converted to wastewater volumes per capita in a
sanitary sewer, or can be related to rainfall in a storm sewer.  The
velocity, depth, and slopes measured can be used to compute Manning's
coeeficient of the roughness-friction factor.  The salt-concentration
method of measuring velocity was best suited for developing a discharge-
depth relationship for a number of sewers, as well as giving an indica-
tion of the condition of the sewer.  The equation applicable for the
salt-concentration method is Q = AV, where: Q is the discharge; A is
the area, computed from the measurement of the flow depth; and, V is
the velocity measurement.  The equipment needed, procedure, analyses of
data, and continuous gaging methods are discussed in detail.  It is con-
cluded that there is no ratio, which when applied to surface velocity
measurements, will give accurate average velocities in a pipe.  Results
of the studies indicate, however, that a ratio of .75 will give a good
approximation for flow depths between .2 and .4 of the pipe diameter.

A rapid  computation of routed  flood hydrographs  in  circular sewers  was

but  this method requires use of a large  computer and a comparatively
large  amount of computer time.  The progressive  average-lag method,
fully  describ'ed in  the article, is used  to carry out the  evaluation
in real  time (i.e., when rainfall is occurring and  before the  flood
wave travels far  down the  channel).  The routing constants of  this
method are  determined by comparing the  results of this method with
those  from  the method of characteristics until good agreement  is
obtained.   It has not been possible to  determine the routing constants
in the progressive  average-lag method analytically.

The hydraulic design of large surge tanks is  described, placing emphasis
on designs used for the Tehachapi surge tank.  Graphical and analytical
methods for determining the size of large surge tanks for pumping plants
are given.  Energy loss coefficients for different orifice configurations
tested are included.  Surge tanks are used to control transient pressures
and to prevent water column separation.  Flow in discharge lines communica-
tions with the surge tank through orifices connecting discharge lines with
the tank is related.  Normal operation produces changes in flow rates in
discharge lines, resulting in positive or negative transient pressure
waves reflected at the surge tank as minor fluctuations in water surface
elevation protecting discharge lines and downstream tunnels from these
surges.  During emergency conditions all pumps could be shut down at
once by a power failure.  This condition causes the pumps to halt, changing
rotational direction as soon as water begins  to flow back.  The reverse
flow continues until the downstream valves are closed.  To prevent low
pressures in discharge  lines or water column  separation under this condi-
tion, water is supplied from the surge tank.

 In Houghton, Michigan, a cold-climate  town,  water pollution  and sewage
 problems  are serious due to the sand and grit  from  street  traction
 abrasives, which enter sewer  interceptors during rain  and  spring  thaw
 conditions.  Not only do the  interceptors become clogged and sewers
 inoperable, but public health is threatened  by unclean water developing
 from overflow  bypassing  treatment.  The  town hired  a company this year
 to utilize traditional cleaning techniques to  unclog the sewer system.
 The  line  was only  two years old and designed to self-clean,  but pre-

solutions of different chemicals.  The most promising treatments were
examined in a single test in July, 1969 in the sewer lines of Sacramento

but some were more effective than others in killing roots  in and outside
of joints.  Studies are being continued to evaluate factors influencing

Pilot-scale  experiments are reported on the effect  of adding polymers
to sewers in order  to increase  the  rate of flow of  the sewage and thus
reduce  surcharging  and/or overflow  from sewers.  The tests showed that
sewage  flow  could be increased  by a factor of two or more by adding
45-200  ml of polymer per litre.  The concentration  required depended
on the  additive used, the concentration of sewage,  the flow increase
desired, and the temperature.   Experiments showed that the additives
used did not have an adverse effect on sewage bacteria or fish and did
not encourage algal growths in  receiving  streams.   They tended to
improve the  rates of sedimentation  and sludge dewatering in the  sewage
works.  Economic analyses showed that, for a given  example, the  cost
of eliminating overflow from a  constriction by use  of additives  was less
than half the cost  of installing an additional sewer.  However,  there
are certain  limits  to the use of additives as a long-term solution to
such problems.

Identifiers:  *Sewer hydraulics, *Chemical  additives.

It is possible today to increase the flow of sewage in an existing sewer
without increasing the fluid head.   This increase can be made by the
addition of selective chemicals.  The flow in an overflowing sewer may
be increased to the extent that sewage does not back up in the sewer
manhole and overflow into streams and house basements.  By using these
chemicals, it is possible for a community to relieve sewer lines of
their periodic peak loads without resorting to expensive relief sewers.
Data measured during an extensive test program show  that flow can be
increased approximately 2.5 times original flow.  Measurements were
made on a test facility utilizing six-inch sewer pipe (plus auxiliary
equipment required to operate the test facility).  Biochemical tests
were conducted on sewage, sewage bacteria, fish, and algae to determine
adverse effects of chemical additives to sewerage or receiving streams.
No significant adverse effects were found.  A cost/effectiveness analysis
showed that, for a sample case, it  cost less than one half as much to
use chemicals to relieve an overflowing sewer than to put in a relief line.
Development of improved flow characteristics was based upon work per-
formed by The Western Company, in improving its oil field servicing
activities.

Identifiers:  *Sewer hydraulics, ^Capacity, *Sewage tunnels.

The author contends that: 1) the main concern in the design of sewage
tunnels is the transportation of incoming grit and sewage material;
2) the transporting capacity of water is important because of its
bearing upon the possible clogging of sewers; 3) the minimum traction
assumed in the design of sewer tunnels must be adequate to keep it
thoroughly flushed; and, 4) the application of existing bed load formu-
las to fixed bed channels is not desirable.

Following a general review of the analytical and experimental information
on the friction loss encountered by fluids flowing in annular pipes, with
particular regard to the influence of eccentricity of the inner member,
experiments are described on an evaluation of the friction of water in a
steel annular pipe of diameter ratios 5.8 and 3.2 in the Reynolds number
range of ten to the fifth power to ten to the sixth power.  It is found
that on a discharge basis, for the same head loss in a given length, with
the diameter ratio of 5.8 the flow capacity of the pipe line is decreased
12.7% in the concentric situation but only 4.5% with full eccentricity.
The latter decrease is not greatly different from the 3% reduction in
area due to the inserted smaller pipe.  An analysis is included showing
that for the simple insert at full eccentricity the near-full-flow capac-
ity of a sewer is little affected.  The effects of hangers such as might
be employed to support inserts in sewers is found to have an appreciable
effect on the flow capacity of a full-flowing sewer.

Results of an experimental study on storm runoff in an urban area showed

flooding were hydraulically identical phenomena.  These experiments were
made for sewer slopes of 1/200 and 1/1000.  The control structures had

in the lower area was concerned or when the drainage pump capacity was
designed to be depressed.   Flooding does not always occur by increasing
the return period, because the maximum rate of runoff becomes a steady

Sewage flows and water demands measured  at two household observation
stations, as well as water and wastewater flows from individual fixtures
and appliances are used to estimate upper limits  of pump and storage
capacities for a storage-grinder-pump unit for individual homes and to
examine the relationship between peak rates of sewage flow and corres-
ponding water demand rates.  For individual fixtures, combination of
rate, duration?and frequency  of discharge that will produce maximum
hydraulic loading conditions  are selected.  Single-fixture hydrographs
are combined to produce synthetic hydrographs of  peak period sewage
discharge, from which combinations of storage and pump capacities are
derived.  Peak sewage flows and simultaneous  water demands for a fourteen
day period at one house are presented and analysed.

This round  table discussion describes the general picture  of  the  storm
and sanitary sewerage systems, including the ranges and sizes  of  each
of the  types of sewers, of the cities the participants represent.   Each
participant also relates his city's problems in regard to  the  effect of
combined sewers on treatment plants and under conditions of storm flow.
Three of the cities have implemented separate sewers, while three others
have not undergone separation because of its high cost.  Our  city has
proposed a  less costly plan of eliminating ground water seepage into
sewers, and the last city  (the only one located in Canada) has not yet
estimated  the cost of separation.

sewers  for  separation in representative combined sewer areas from lay-
outs by the Project staff.   The Boston study researched  the  53-acre
gently  sloping, heterogeneous commercial Summer Street Separation Study
Area.   The  report describes  the separation  of building plumbing in de-
tail in a typical three-quarter century old five story and basement
commercial  building 65-ft. by 145-ft. in plan, and estimates the cost
of plumbing separation.  Four alternative pressure sewer collection
systems are indicated with plans and hydraulic profiles.  Some systems
included in-line main pumping stations.  The least expensive complete
pressure system, which did not include a main pumping station, is
estimated to  cost $4,700,000.  Both costs include costs  of building
plumbing separation,  $4,000,000 for the pressure system  including com-
munitors, wet walls and non-clog pumps, and 2,000,000 for the  gravity
systems.

The feasibility, selection of systems  components,  and the development
of a new method for separating community wastewaters and runoff from
rainfall and snowmelt in areas served  by combined  and intercepting
sewers are reported on the basis of information drawn from 25 projects'
reports and technical memoranda  whose  abstracts are  appended in this
final compilation.   The general concept  involves pumping ground waste-
water from buildings through pressure  tubing connected to street pressure
conduits discharging in turn into interceptors. The tubing and conduits
would be contained  within existing combined  sewers,  thus allowing runoff
from rainfall and snowmelt to be removed from the  community unencumbered
by wastewaters.   Pressure conduits suspended inside  combined sewers can
be entered by workmen, but generally this  system will cost more than
new gravity systems,

Assistance was provided in connection with special field trial instal-
lations of flexible tubing inserted in building sewers.  Materials were
proposed for pushing or pulling through a building sewer and a method-
ology and necessary attachments and tools were recommended.  Polyethylene
and polybuthylene tubing are recommended for use inside building sewers,
and copper tubing for use in open trenches.  A saddle type of connection
is recommended for connecting pressure tubing to street pressure conduits.
Cast iron, PVC, asbestos cement, or ductile iron are recommended for
pressure conduits.  Experience with the plowing of a pressure pipe is
reviewed.  Reference is made to the standard practice for trench instal-
lations, street crossings, and thrust blocking.  Two methods of clean-
ing hose pressure tubing are proposed.  Six possible layouts of pres-
sure conduits are discussed in terms of operation and maintenance.  All
six arrangements provide for routine rerouting of flow by exploiting a
dual conduit configuration.

In a paper presented at a seminar on canalization held at Raach, Austria,
in 1967, the author gave details of investigations into the efficiency
of sewerage systems, and outlined the advantages and disadvantages of
separate systems as compared with combined systems.   Describing the de-
sign and construction of each system he emphasized that neither could
be regarded as the more efficient,  and stressed the need for graphical
and hydrographical surveys when sewerage systems are planned and that
the final decision must depend on the purposes which the sewerage system
is to serve.  For small communities,  housing estates, and small hotels
the combined system can be of advantage, provided the discharge of rain-
fall and runoff is controlled and the quality of the receiving waters
is not affected.  Where future plans  require extensions of sewerage
systems, the separate system is more  suitable, as long as operational
control and plant maintenance are carried out regularly.

Rainwater, discharged from combined or separate systems, can have severe
polluting effects on receiving waters especially in iddustrial areas.
Discussing the methods used for reducing such pollution, the author refers
to German specifications for three standard types of stormwater retarding,
tanks, designed to prevent the direct discharge of the first flush of
rainfall and to restrict the flow from being carried forward to receiving
waters or sewage works.  Various methods of calculations for stormwater
retarding tanks in sewerage systems are reviewed and compared as to
their accuracy.  Illustrated details are given of a revised method in
which different rates of flow at varying durations of rainfall can be
calculated using different parameters.

mostly sewered on a partially combined system to a totally inadequate

overloaded.  The basis of the new sewerage system is a trunk sewer laid
from a new sewage disposal works.  Into this main trunk system flow from
area villages will be brought by either pumping or gravity.  Solutions

The Metropolitan Corporation recognized its duties in restoring the
rivers to the requirements of the urban area so that the citizens could
use these rivers for recreational purposes.  This necessitated the ex-
pansion of the existing facilities and the addition of new facilities.
Sewer rentals and industrial wastes were two major areas investigated.
A separate sewer system was looked into by both city and consulting
engineers.  It was decided that the $200 million plus cost of intercept-
ing the old combined system was not feasible; however, future develop-
ment of areas along the Red and Assiniboine Rivers will be based on
separate sewer systems.

with 94% of the population and 84% of the area served by combined sewers,
were interviewed directly.  The results of the survey indicated that
36,236,000 people, living on 3,029,000 acres were served by combined
sewers.  This total indicates that approximately 29% of the nations total
sewered population is served by combined sewers.  The types of problems

Three methods of installing  pressure  tubing from houses or small build-
ings, and of connecting the  tubing  with  street  pressure conduits, are
described and discussed.   One would be the  installation and connection
of pressure tubing and conduit in trenches  by traditional water distri-
bution methods.  Field trials were  conducted to indicate the feasibili-
ty of inserting tubing in building  sewers.   Tubing was  pushed through
an 86-foot long 4- 5-inch diameter  building lateral, which included
three 45 degree bends, from  a specially  dug pit at the  upstream end in-
to a 4-foot diameter combined sewer.   The forward end of the tubing was
guided by a special leader device.  Three fourths-, 1-, and 1 1/2-inch
polyethylene tubing could be pushed.   Polybutylene and  copper tubes
could not be pushed because  they buckled or crimped.  A Kellums grip
and swivel on the end of a rope were  used to pull tubing from the com-
bined sewer to the upstream  pit. Three fourths-, 1-,  and 1 %-inch
polyethylene and  3/4- and 1-inch polybutylene  could be pulled.  Three
fourths-inch copper tubing could not  be pulled  because  of its stiff-
ness.  The third method, tested in  the field, combined  the insertion of
tubing with a street main in the trench. Cost  estimates were made for
the latter two methods.

runoff, the greatest bulk of BOD and suspended solids will be captured.
Parameters to be measured and evaluated to determine the efficiency of
the system are listed.

COMBINED SEWERS IN CANADA,

D. H. Waller
Eng J, Vol 52, No 6, pp 22-30, Jun 1969.
Paper presented at the Annual General Meeting of the Engineering Insti-
tute of Canada, May 29-31, 1968.

Descriptors:  *Sewers, ^Surveys, Overflow, Separation techniques.
Identifiers:  *Combined sewers, *Canada.

The author presents a survey of combined sewers in Canada similar to the
one he undertook in 1967 on the same subject in the United States.   Even
when combined sewers are large enough to carry peak storm flows in addi-
tion to domestic sewage, they do not provide the higher velocities in
dry weather that are needed to prevent solid deposition.   Thus, up to
1/3 the annual production of solids and BOD may be overflowed during
storms and held back from treatment.  Problems such as these necessi-
tated this study which provides information in four main areas:  1)  the
extent and distribution of Canada's combined sewers; 2) the prevailing
attitudes and policies in regard to combined sewers; 3) factors influ-
encing these attitudes and policies; and 4) descriptions of methods  pro-
posed and adopted to diminish overflows from combined sewers.  A majori-
ty of the population surveyed considered combined sewer overflows to be
a nuisance.  Separation is too expensive to warrant institution in most
communities.  Some combined systems have not yet developed to the point
where they include overflow, and in some areas the pollution from this
source is not considered to be a problem.  More information is needed
regarding less-costly alternatives to separation.  Separation should be
implemented without delay for flood relief, when combined sewers are re-
placed and in new construction, or in plumbing for new buildings.  These
programs are not overly expensive, and they leave open the option of in-
stituting alternatives which future technology may uncover.

A sewerage reconstruction program  in  the Burslem area of Stoke-on-Trent
involves a four-stage renewal of the  sewer system and reconstruction of
the water pollution control works.  Old sewers  were in poor structural
and hydraulic condition, and several  sections of the main outfall sewer
upstream of the treatment works collapsed causing crude sewage to over-
flow and form a large lake of sewage.   Two contracts provided a sanitary
sewer from the works plus a surface water culvert connecting with a feed-
er to the River Trent.  A third contract provided a separate storm and
sanitary system connecting the old  sewer network with the sewer and
culvert constructed previously. Other structures built under the con-
tract are described.

 Descriptors:  ^Pressure  conduits,  Separation techniques.
 Identifiers:  ^Combined  sewers, ^Sanitary sewage, Comminuted sewage.

 Descriptions  of  the project separation scheme,  project  goal and  project
 background  are given.  The general concept of the ASCE  Project scheme  is
 to pump  comminuted sanitary sewage from individual buildings and building
 complexes through relatively small pressure  tubing laid in existing build-
 ing  connections  and thence into new pressure conduits suspended  in exist-
 ing  street  sewers.  Potential  advantages of  the  scheme  are discussed.
 The  project wishes  to develop  feasible designs  and operations  and to
                                  80

test them in actual systems.  The immediate objective is to examine and
evaluate both the feasibility and probable cost.  The background of
the project is reviewed.  An appendix summarizes the need for separation
of combined sewerage systems and the national scope of the problem.

Descriptors:  ^Maintenance,  ^Repairing, Infiltration.

The North Tahoe Public Utility  District instituted a massive sewer
repair program after it  discovered  that sewage  flows were highly
excessive.  Snow Creek and  Lake Tahoe were becoming polluted, 200
manholes were leaking and permitting entrance of surface and ground
water, and many lateral  sewers  were causing infiltration.  Smoke
bombs employed to pinpoint  offenders disclosed  storm inlets connected
to sanitary sewers.  Methods used to correct violations and sewer
defects  are described.

 Residential sewage flow  criteria are developed for use in design of
 pressurized sanitary  sewers  for hypothetical applications of the ASCE
 Project scheme.  In a typical combined sewer area, data on domestic water
 demands is the most that can be expected to be available.  On the basis
 of a study of winter  water demand data it is concluded that projection
 of such observed demands for a service area to the end of the design
 period is the preferred  basis of design.  Data for California and the
 northeastern United States are presented separately.  For each region,
 design curves represent  the  variation, as a function of the number of
 dwelling units served, of  flow for the minimum 24 hours, for the peak
 hour of the minimum day, and for the maximum peak hour of any day,
 expressed as ratios to the annual average rate.

Raw sewage, with and without particle-size reduction by comminution,
was pumped through 2-in. to 8-in.  clear plastic pipe.   Extensive
observation indicated rather conclusively that the material last to be
scoured and first to be deposited was predominantly sand.   For all
tests, the sewage was salted with ground egg shells but these were al-
ways moved at lower mean flow velocities than the sand, which was in
low concentrations, viz., 8 to 78 ppm.   No discernable difference was
noted in the minimum transport velocities for comminuted and un-
comminuted sewage, and the difference between minimum scouring veloc-
ities and maximum depositing velocities  was small.   Test results were
blended with those from sand transport  experiments  elsewhere for general
representation.   Exploratory open channel tests were made  with the
8-in. pipe for a firmer correlation with sand tests.   Results are pre-
sented in terms  of dimensionless  parameters.   Limited tests were made
on 8-in. spiral  corrugated pipe.

 Tue article describes how a municipal storm sewer section, solidly
 plugged with a mixture of mud and water, ruptured and was repaired.
 Three  steps were  taken to correct the damage:  1) temporary  lines were
 laid along the surface and the mains were pumped through these surface
 lines; 2) drop manholes were constructed at two sides of the threatened
 area;  and, 3)  three pumps were used to by-pass the plugged section of
 the line.  The emergency measures  for the public are related, and the
 theoretical causes for the break  are included.  The cost of  repair for
 this unexplained  occurrence is given.

In Medary, Wisconsin, a storm sewer, washed out by heavy rainfall, was
repaired in twelve days.  The Wisconsin Culvert Co. recommended that
the now exposed area, which had previously held a 750 foot-long piece
of a 72 inch diameter storm sewer pipe, be contained by fabricating a
96 inch diameter drop inlet constructed of 8-gage corrugated galvinized
steel, closely riveted and caulked.  The drop inlet would connect to
the existing 72 inch line by means of a watertight 84 inch diameter,
8-gage galvinized steel pipe, close riveted and caulked, outlet connected
at the base of the drop inlet would run 400 feet along the gouged ditch
line.  The method was approved and immediate fabrication of sections of
the drop inlet began followed by trucking of these sections to the site
and their installation.

A description of the  storm sewer system situation in Medary, Wisconsin
prior to the overflow in June 1968 is given.  The article states that
the failure of the sewer line in Medary was not due to the design of
the storm sewer system, the installation of the pipe, or the type of
pipe used.  Two reasons are given as to the cause of the overflow:
modifications to the  storm sewer without informing the consultant
engineer; and, lack of knowledge or consideration of hydraulic

The Department of Public Works of the City  of St.  Paul,  Minnesota,

is developing a drop-shaft design which  will reduce  the  possibility
of impact damage to the structure and also  insure  stable flow con-
ditions in the underground interceptors.  It was found that past de-
signs required frequent inspection and maintenance at the base of the
shaft to prevent failure of the structure.   An experimental study led
to the development of an impact-cup  type of drop structure which could
be effectively used to convey storm  runoff  waters  from the surface to
subterranean collecting systems with  a minimum of  air entrainment and
a reduction in possible damage at the base  of the  drop.   Pictures and
measured sketches of the designs are  included.

Wisconsin cities with populations of 7,500 to over 60,000 are developing
comprehensive plans with all storm sewer designs done by registered pro-
fessional engineers.  Storms with 5 to 10 yr frequency are used in design.
Two-foot inlest depressed one in., 12-in. minimum pipe size, and pipe
velocities  of 2 to 15 fps are common.  Urban drainage designers who
provided current practice, policy, procedure and cost information for
a  typical 15-acre, 6-block area indicated wide diversity in results when
using the Rational Method to compute flows.  Only 6 of 23 cities which
contributed sample designs used variable intensities correctly in the
Rational Method.  Errors in the use of the runoff coefficient C were
common.  Total project  costs varied from $8,000 to $65,000 for this
sample  area.  The need  for narrower guide lines for design is suggested.

The  method  of a  storm drainage system design is presented which utilizes

The  system  is designed for critical periods when flow in a system or
parts of a  system  is maximum as determined from a hydrograph of the run-
off.  This  method  is particularly suited for the design of submerged
systems, and therefore, it was computerized.  The results of a sample
problem show larger pipe sizes than would be found when using the con-
ventional method which adds times of flow in lines to concentration
time at some arbitrary starting point.

MULTI-MEANS EFFORT FOR URBAN FLOOD CONTROL,

Paper presented at International Conference on Floods:  Their Protection
and Defense of the Soil, held by the academia Nazionale Dei Lincei,
Rome, Italy, Nov 1969.

Descriptors:  *Flood  control, *Planning, *Drainage systems, *Drainage
engineering, Storm drains, Storm runoff, Drainage programs, Hydraulic
structures, Water policy.

Urban drainage is usually very localized, although it is believed that
damages due to urban  drainage problems are equal to report flood losses.

An effective way  to  deal with  this problem is by a multiple means effort
based  on  a basic  urban drainage policy.  Such a policy  should be formu-
lated  in  lieu  of  various inputs, principles of urban  drainage, hydrology
and hydraulics  of small urban  basins,  and accurate knowledge of urban
drainage  law.   Urban drainage  policy must also recognize  that urban
drainage  is  directly related to the total urban system.   The planning
process is based  on  the concept of two urban drainage systems.  The
initial drainage  system, typically storm sewers, is designed to handle
storm  runoff  expected to occur once every 2-10 years.   The major drainage
system is the  area which must  accomodate the 100-year runoff and includes
both natural  and  artificial elements.  Other specific aspects of urban
drainage  planning discussed are functions of storm sewers and streets,
hydraulic structures, inlets and  culverts, storage and  floodproofing.

(basins). Runoff, Pesticides.
Identifiers:  *Environmental pollution, *Storm sewers, *Combined sewers,

 The  environmental pollution factors  and  their potential pollutional ef-
 fects  resulting  from the  water-wastes  interfacial  contracts during pre-
 cipitation  and runoff have been analyzed based  upon  collected field data
 and  theoretical  calculations.   The surface  urban environment factors
 studied  included,  street  refuse and  litter,  catch  basins, environmentally
 used chemicals,  contributions  from air pollution and its  control, and
 sewer  solids  deposition.   It was found that street refuse could present
 a  significant pollution load.   It is estimated  that  a pollution load -
 measured in terms of BOD  - of  a) 1%  of the  total raw sewage or 5% of the
 total  secondary  treatment effluent in  terms of  average daily load, and
                                95

findings and recommendations, raw data collected, survey questionnaires,
and a comprehensive set of ordinances govering a wide sampling of possi-
ble sources of urban storm water pollution are compiled in this report.

Tables are included showing the 1967 revision of the scheme used for
classification of water according to the intended uses and the corre-
sponding physico-chemical and bacteriological standards.  Each state has
been classifying the interstate streams, and subsequent to approval of
the classification by the Commission, each state will undertake estab-
lishing a program for treatment of sewage and waste waters to meet the
appropriate standards.  Progress in the planning and construction of
treatment plants is summarized for the individual states, and some indi-
vidual states, and some individual plants are described and illustrated.
Research has included studies on the legal aspects of water right and

Identifiers:  *Water quality criteria,  Hydrological surveys.

Progress in cooperative work on the management of water quality in the
Ohio River valley  is reviewed.  The 18th yearbook contains the criteria
which have been recommended for water quality.  Since the Water Quality
Act of 1965 required the establishment  of water quality standards for
the individual states, a major problem  is the reconciliation of standards,
especially where different  standards are applied to the same stretch of
river bordering two states.  Other projects include: expansion of the
system for monitoring water quality, appraising river conditions, and
forecasting impending changes some days in advance; development of auto-
mated forecasting  procedures for management of water quality using a
mathematical model; geological and hydrological surveys to determine the
potentialities and limitations of deep  wells for the disposal of diffi-
cult or toxic waste waters; assessment  of changes in aquatic life; and,
investigations on  the enrichment of oxygen in rivers by various methods
of operation at hydroelectric power facilities.  Each yearbook includes
data on the individual water quality characteristics in the Ohio River
and its tributaries, and on the present status of municipal and indus-
trial pollution control facilities.  The 20th yearbook also contains an
article by R. H. Leach, reviewing the accomplishments of the Commision
during the 20 years since its establishment.

Sewer maintenance problems in Ottawa include threatened explosions due to
improper sewer ventilation during snow and sleet storms, the entrance of
granular street materials into catch basins and then the sewer systems,
and the handling of excess runoff during spring thaws.  The problem
caused by the entrance of sand and peastone traction materials into the
sewer system is greatest in the city's combined sewer district where
pipes are older and laid on flatter grades than those of the newer sepa-
rate system.  Means of combating Ottawa*a sewer maintenance problems are
discussed.  Two programs adopted are the crash maintenance program during
spring  to remove grit in flat sewers, thus allowing sewers maximum capac-
ity  for spring  runoff; and the development of detained  sewer maintenance
records which are made available to crews handling sewer problems.

runoff pollution.  Town Lake, in Austin, is small and narrow and receives
some urban runoff pollution.  Oxygen concentration/water depth data for
the 3 reservoirs are tabulated.  In Lake Travis, even in the winter, the
temperature varied with depth.  During the summer, the oxygen first be-
came depleted at the thermocline region.  Throughout the fall, various
depths of Lake Travis became reaerated, but oxygen-depleted waters were
still passing through the penstocks in November.  In winter, oxygen was
present at all depths.  In Lake Austin, the summer oxygen concentration
in the epilimnion varied around saturation.  Dissolved oxygen decreased
steadily in the hypolimnion during the summer and was consistently lower
above the sediments.  After autumn turnover, oxygen remained uniform from
top to bottom.  High numbers of total and coliform bacteria were found in
Lake Austin during  the spring  following periods of intensive rainfall.
The urban stream, Barton Creek, had significantly higher concentrations
of solutes, nutrients, and bacteria than Town Lake above the stream's
entrance, particularly during  the  spring rainfall period.  All of Austin's
urban streams enter Town Lake  and  Lake Austin, with the streams from the
more highly developed areas entering Town  Lake.

-------
pollution abatement philosophies are considered.  The needs for  problem
definitions are delineated along with pertinent constraints of existing
methodology and measuring instrumentation.  Costs and economic analysis
of some abatement schemes are evaluated.  Complete separation of storm-
water and sanitary wastes, storage in conduit or detention basins,  a
total systems concept and microstraining, chlorination, and ozonation  of
discharges are some of the principles reported for the control and  treat-
ment of combined sewer overflows.   The authors basically recommend  partial
separation in certain areas of the City and alternate methods or the
continuance of combined sewerage for the remaining areas.  However,
further knowledge is needed regarding all types of sewerage systems and
treatment.

Many other wells are sampled at infrequent intervals by these and other
agencies.  The efficiency and completeness of the entire network are
evaluated, and changes in standards for the network are suggested.  Com-
plete chemical analysis of a water sample is not always necessary.  Selec-
tive analyses suggested for obtaining specific types of data include:
(1) Chloride determination and electrical conductivity measurements on
samples from aquifers susceptible to intrusion of sea water; (2) sulfate,
bicarbonate, and nitrate determinations on samples from aquifers under-
lying the forebay area; and (3) sodium, sulfate, chloride, and boron
determinations and electrical conductivity measurements on samples  from
aquifers  used as a source of irrigation water.

Magnetic microspherical particles which occur in the bottom muds of Lake
Mendota have been analysed  chemically and mineralogically.  The data sug-

domestic activities and are being supplied to the lake either through the
action of washing the  atmosphere or  as the detrital load of the influent
streams and urban runoff..  These particles are.apparently unaffected by
diagenetic changes and since the chronological pattern of the lake sedi-
mentation is well documented, the distribution of these microspherical
particles has been used to  evaluate  the role of man in the trophic evolu-
tion of the lake.

 The ASCE Committee on Sewerage and Sewage Treatment distributed a ques-
 tionnaire to members of the Sanitary Engineering Division in  order to
 determine the attitudes and opinions of members in regard to  existing
 and future research and development, the social and economic  value of
 alternate beneficial uses  of the Nation's water, and to  demonstrate an
 algorithmic technique for  quantifying probabilistic or nondeterministic
 data.   Results of the questionnaire are listed and interpreted.   Respond-
 ing engineers generally indicated that sewer and storm drain  design would
 benefit least from existing or future research and development  work.  The
 authors conclude that it is possible and desirable to quantify  qualitative
 factors relating to engineering decisions.   Also,  as algorithmic methods
 are used increasingly, future technical refinements may  be expected.

 Continuous  water quality monitors have  been  used by the Technical Ser-

 in a variety of  field water pollution studies  and  for various  purposes.
 Two  commercially available  types  of monitors have been  used.   Monitors
 were used in the James River Project along with recording  flow gages to
 determine the relationship between  stream  quality  and storm runoff.   In
 a  before-and-after type study  to  determine differences  in  quality due to
 navigation  impoundments, monitors were  used  to establish the existing
 quality  of  the waterway.  In a research study  of a  refinery waste treat-
 ment plant,  a monitor was used to study the  various unit processes for
 purposes of treatment control  and overall  refinery  waste monitoring.
 The  sample  taking capability of the monitors was indispensable in an
 enforcement case involving  a mine waste.

*Water pollution sources, *Testing.
Identifiers:  *Fecal coliforms, *Tennessee Valley.


Recent limited stormwater bacteriological water-quality sampling in the
Tennessee Valley indicates  that high  fecal coliform loads are common in
stormwater  runoff.  In clean residential areas  sustained high fecal co-
liform loads were  observed  uring stormwater  runoff.  The source of these
loads was associated with overland  flow, and it appears that staggered
contributing times account  for the  sustained high loads.  High fecal co-
liform counts were also measured in stormwaters originating from agricul-
tural areas and  forested watersheds.   The consistency with which fecal
coliform counts  in excess of accepted standards are commonly found fur-
ther substantiates the need for a reappraisal of this test as an indica-
tor of pathogenic  organisms.  These data also point to the importance of
recognizing the  streamflow  regime in  the analysis of water-quality sampl-
ing data since observations taken during storm  periods usually in high
bacteriological  loads.

 An investigation  of  the  pollution concentrations and loads from storm
 water runoff in an urban area was conducted in Tulsa, Oklahoma during
 the period from October  1968  to September  1969.  The scope of the project
 included  a field  assessment of the storm water pollution by  obtaining
 samples of the water resulting from rainfall and surface runoff from test
 sites in  the metropolitan  area; development of an analytical procedure
 for correlation of storm water pollution with defined variables of land
 uses, environmental  conditions, drainage characteristics, and rainfall;
 and development of an  abatement plan  for pollution  in urban  areas.  Run-
 off samples were  analyzed  in  terms of  quality standards for  BOD, COD,

Identifiers:   Seasonal survival study.

A three-year study was made on the survival of  selected strains of
Escherichia coli and Streptococcus faecdlis in  shaded and exposed out-
door soil plots.  The soils were dosed periodically,  and subsequent re-
ductions in survival are shown graphically as seasons variate.   Periods
for 90-per cent reduction of Esch.  coli.  ranged  from 3.3 days In summer
to 13.4 days  in autumn and for S.  faecalis from 2.7 days in summer to
20.1 in winter.  During  the fall,  the survival  periods for the organisms
were the same,  but in spring and winter  Streptococcus survived longer.
Both organisms could be  isolated from runoff during period of heavy
rainfall in spring;  however,  isolation during summer and autumn months
was sporadic.  On account of these results and  other factors, it was
considered that Esch.  coli was the better indicator of pollution.

Descriptors:   Storm runoff.
Identifiers:   Fecal coliforms, Fecal streptococci, Stream pollution.

Results of an  intensive study on the occurrence and  strain  distribution
for  12, 536  fecal streptococcus strains found in warm-blooded animal  feces
and  numerous water sources from a wide geographical  area  reveal  several
new  factors  that must be understood for a proper interpretation  of  the
sanitary significance of this bacterial group in water  pollution studies.
These  studies  were conducted  in streams,  agricultural waters, recrea-
tional and public water sources, and on domestic wastewater and  storm-
water  and food processing wastes.  The ubiquity of Streptococcus faecalis
var. liquifaciens in  the water environment  and the occasional occurrence
of an  atypical S. faecalis associated with  vegetation shows the  need  for
including the  fecal coliform  examination  in recreational  water quality
measurements.   Applications of the fecal  streptococcus  indicator system
in stream pollution are the development of  fecal coliform to fecal
                                  104

-------
streptococcus ratios that will further define possible sources of the
fecal discharge into the stream; and the detection of the S bovis and
S. equinus subgroup which was not found in human feces and may be con-

Identifiers:  *Fecal coliforms.

The bacteriological composition of stormwater from a variety of areas
was compared and seasonal differences noted.   Higher numbers of organisms
appear to persist during winter than during summer.   The fecal coliform
segment of the total coliform population for all stormwater samples
averaged 8.6 percent; however, 21.1 percent fecal coliforms were observed
in stormwater taken in autumn from a suburban business district.  Evi-
dence indicates that fecal contamination in separate stormwater systems
originates from cat and dog deposits on soil and from rodent deposits in
urban areas.  Thus, regulations to prohibit pets on public beaches and
improved garbage control plans to discourage rodent proliferation are
recommended.  Also, diversion of storm drains and land drainage away
from beaches and reservoirs would aid in reducing bacterial contamination.

Sediment derived  from  construction  in areas  of urban  growth has profound
impact on downstream channels and water resources.  Such sediment pollu-
tion is usually much more  dynamic and intense than sediment derived from
rural areas.  Research needs concerning urban drived  sediment are similar
to those already  underway  in rural  areas; however, new emphasis must be
given to exposed  subsoils,  to problems in existing stream  channels, to
pollution of existing  and  future water resources, and to more effective
                                  105

-------
planning and phasing of construction.  Storm drainage, that flows through
existing and new channels that are later complicated by urban changes,  is
a foremost topic of urban hydrology; and it is discussed in this article.
Some of the needed soils and stream channel research can be accomplished
in laboratories, but much needs to be done on small areas at the constru-
tion sites.  Although many urban research methods can be adapted from
related rural programs, consideration must be given to the fact that the
extent and location of the exposed subsoils in the drainage basin will
change rapidly and that extremely high and variable sediment loads will be
imposed upon the stream channels.  Better planning and legal backing will
make research findings more useful.

Decriptors:  *Pseudomonas, *Drainage, Indicators.
Identifiers:  *Pseudomonas aeruginosa.

Although sewage discharges represent major potential sources of P.
aeruginosa in the environment, storm drainage from municipal areas con-
tributes continuous inoculum to surface waters.  Farm drainage also can
contain small numbers of bacteria under certain conditions.  Relatively
heavy populations of P. aerug'lnosa in streams below sewage outfalls, de-
crease rapidly as they progress downstream.  The usefulness of this
organism as an indicator of the possible presence of enteric pathogens
is therefore limited.

Studies on the ecology of Pseudomonas aeruginosa in surface  and  tap waters

contribute small numbers of Pseudomonas, sewage discharges probably repre-
sent the major source of these organisms entering streams, particularly
discharges of crude sewage which may contain up to 7 x 105 organisms per
100 ml.  Although secondary sewage treatment reduces the number of
Pseudonomas in domestic sewage by about 99 per cent, growth of the
organism has been observed during treatment of slaughterhouse wastewaters.
Populations of less than 100 per 100 ml occurred in surface waters near
areas of human activity but not directly receiving sewage discharges;
however, populations of about 100 per 100 ml were detected in public
bathing waters in the Madison lakes, Wis., and very much greater popula-
tions were observed in waters recently contaminated with sewage.  Although
some sterile natural waters supported growth of Pseudonomas in the labora-
tory, populations of viable Pseudonomas were reduced rapidly in natural
surface waters, with reductions of more than 90 percent in three hours.
It is concluded that Pseudonomas aevug-inosa is a sensitive indicator of
pollution of surface waters by sewage and by runoff from urban areas and
farmyards.

The quality  and  quantity  of  runoff  from street washing  operations in
Minsk were measured  to  study the  contribution of  street washing  to water
pollution.   Data from earlier studies  in Moscow and  Leningrad  are included
                                107

-------
for comparison.  The BOD of street cleaning runoff is 6-223 mg/liter,
petroleum products are up to 110 mg/litter, and coliforms are nearly as
abundant as in wastewater.   These waters, unless they are treated, can
be a major source of pollution.

Water Res, Vol 2, No 1, pp 24-26, Jan 1968.

Descriptors:  ^Surface runoff, *Water quality, Data collections,
Evaluation.
Identifiers:  ^Surface runoff pollution, *USSR.

The  extent of surface runoff pollution was calculated in  the Minsk  and
Soligorsk districts using the five-day BOD as the main index.   Other
data were accumulated to determine the variations in the  quality  of the
water when compared with the type of storm, the length of  the previous
dry  weather period, the season, the surface of the region,  and  the  amount
of transport and pedestrian traffic.  With these results,  evaluations
can  be made of the influences of the pollutants and of the  effects  of
measures such as catch basins, settling basins, storm sewers, and in-
creased sewer capacity, on the maintenance of sanitary pond conditions.

 Recommendations are made for further study in the area of identifying
 sources and constituents of urban runoff through the development and
 testing of urban water quality models and through the national  collection
 of urban water quality data.  Possible sources of pollutants and consti-
 tuents of stormwater runoff are described with emphasis on a primary pol-
 lutant, sediment.  Approaches to the development of water quality models
 are discussed.

Identifiers:  Storm sewers, Sewer separation.

This short review summarizes environmental problems in the United
States such as water pollution, refuse collection and disposal, min-
eral depletion, and air pollution.   Under water pollution, it is noted
that $48 billion is required to separate sewers in the U.S. in order
to correct effects of stormwater overflow.  Grim predictions concern-
ing the environment are made, and immediate action to improve condi-
tions is advocated.

Identifiers:  ^Viewpoint, *Mole.

Dr. Walter Hibbard,  Jr., Bureau of  the Mines  Director, recently empha-
sized the need for more research  and development on mechanized tunnel-
ing.  There is a growing demand for tunnels for the following purposes:
subways, utilities,  transmission  lines, mining, and urban freeways.
Needs in each of these areas are  discussed as are advances already
made with the mole borer.  Savings  in the billion-dollar range are
possible with advanced tunneling  procedures.   In addition to perfecting
moles, guidance control, placement  of lining, and methods for the
transportation of muck out of the tunnel must be developed.

river.  The greatest effect of the discharge from the Greater London
Council sewage works on the tidal Thames originated from the outfall
works at Beckton.  A scheme for reduction in storm sewage discharges
from the sewerage system leading to the Beckton works was being
examined.  New trunk sewers, a pumping plant, and storm sewage tanks
would be most likely involved in the scheme.  The cost of the Beckton
improvements was estimated at 21 million pounds, and of the improve-
ments of the sewerage and storm sewage disposal systems at 22 million
pounds.

The Agency for International Development (AID) is conducting a 15-month,
$800,000 study to discover  the most efficient and economic sewer system
for the disposal of Saigon's sewage and stormwater runoff.  The present
system is almost entirely non-functioning and as a result, the water-
ways of the city, including the Saigon River, are highly polluted with
human waste and refuse.  One plan to be explored is a drainage canal
system for stormwater that  would double as a transportation system.
The results of the study will be used to support requests for financial
assistance for reconstructing Saigon's sewers.

 Chicago is building a $14.4-million deep tunnel system to carry  spil-
 lages from combined storm and sanitary sewers  during rainfall.   The
 FWPCA has indicated four main areas related to stormwater runoff
 problems which require further study and demonstration:   drainage area
 control; collection system control; external discharge control,  includ-
 ing treatment of both combined sew'er overflow  and stormwater run-off;
                                111

-------
and a miscellaneous area, consisting of the economic feasibility of
substituting separate sewers for combined sewers and local for central
treatment facilities,  better hydrologic analyses, new management pro-
cedures, construction materials and methods, and the development of
performance criteria for standards of water quality.

S. 3472, the program for water pollution cleanup, calls for $10 billion
for construction of municipal waste treatment plants.   Among spokesmen
at the 4th Annual Legislative Seminar concerned with the continuing
cleanup is James R. Ellis who states that  cities are in a catch-up
situation.  According to Ellis, 35% of the sewered population in the
United States received 5% of the federal dollar during the period
1965 - 1969.  Some of Ellis' suggestions are cited.  John L. Salisbury,
a Maine spokesman, contends  that the need  for secondary treatment is

An APWA survey indicated that:  1) urban runoff constitutes approximately
1% of the raw sewage load which amounts to 5% of the BOD discharged
from the area's secondary waste treatment facilities; 2) water pollution
from this urban source occurs creating a shock pollution load on receiv-
ing waters; 3) the most determinable measure of pollution potential of
street litter is the BOD load of the soluble dust and dirt fraction;
4) an estimated expenditure of $48 billion would be needed to separate
sanitary and storm waters; and, 5) $15 billion would be needed for
alternate control methods for abatement of combined sewer overflows.

This article describes the twenty-year struggle  that  evolved in Middle-
port,  Ohio  over  the construction of a  sewerage system and treatment
plant.  Without  such  a system, Middleport's  sewage  was dumped raw into
the river.  A  combination of  a lack of funds, the granting of numerous
six-month sewage dumping permits,  and  village councils' opposition
tactics prevented installation of  the  system until  September 1968.
Factory-made compression joint pipe was used to  minimize infiltration
when the river level  is  above the pipe's level.  This vitrified-clay
pipe contains  patented 0-ring joints.

 The Thailand government's decision to plan for drainage and sewerage
 in Bangkok has led to increased research at the Asian Institute of
 Technology in Bangkok.  Studies relating to stormwater collection,
 river pollution,  and sewage treatment have been made in cooperation
 with interested authorities; and the results are applicable not only
 to Bangkok's project but also to other tropical regions.  Topics of
 pertinent research projects include:  (1) the anaerobic treatment of
 tapioca starch waste; (2) characteristics of treatment of Bangkok
 septic-tank sludge; (3)  a Bangkok runoff hydrograph; (4) the ecology
                                 115

of polluted canals in Bangkok; (5) a study of photosynthetic oxygen
production in the Chao Phya River; (6) pollution of the Chao Phya River,
Bangkok; and (7)  oxygen balance in the Chao Phya River estuary.  Re-
search is also proceeding on industrial waste treatment in Southeast
Asia including studies on design criteria for waste stabilization ponds
and sludge drying beds, and the progress of biological assimilation of
wastes in a tropical climate.  Water treatment is another area currently
being investigated.

Identifiers:  ^Separate system, Storm sewage, Great Britain

The Institute of Water Pollution Control gives evidence on and makes
suggestions relating to sewage disposal for a Memorandum to the "Jeger"
Working Party.  Topics discussed are divided into five categories:
(1) public health, (2) amenity, (3) economic effects, (4) sewage treat-
ment and disposal processes, and  (5) administration and standards.
Under the section on amenity, the Institute notes that with regard to
the amenities of  rivers, the major cause of deterioration is the gener-
ally  inadequate provision for sewage disposal integral with residen-
tial and industrial expansion.  Even where adequate sewage treatment
facilities exist, storm-sewage discharges often impair river amenities.
Separate sewer construction is recommended.  Methods of sewage treat-
ment are discussed such as:  sewage sludge utilization after heated
digestion, plus quaternary processes for de-nitrification, de-salination,
and phosphate removal.  Other topics covered are:  trade effluent con-
trol, planning authorities, coastal pollution, settling tank design,
and suggestions for investigational research.

-------
The main purpose of this handbook is to aid engineers in overcoming
problems involved in highway- railway, municipal, agricultural, and
industrial drainage and construction.  The text aims to present engi-
neering practices based on sixty years of practical experience compat-
ible with existing technology.  Design data and designer aids are cited
extensively, while theory is kept at a minimum.  The design and appli-
cation of flexible steel underground conduits, plus good installation
practices, are described in the first two parts of the book.  The third
part concerns other steel products for related construction.  The first
part on general design considerations includes chapters on:  product
details, strength design, service life, hydraulics, cost factors,
couplings and fittings, and installation instructions.  Part II on
applications covers the following subjects:  culverts, sewers, subdrain-
age, airport drainage, erosion prevention, dam and levee drainage, tun-
nels, shafts, caissons, underpasses, and service tunnels.  The book
also contains a glossary of terms, a list of symbols, conversion tables,
general tables, and gage/height-of-cover tables.

This chapter studies product details involved in design of flexible
steel underground conduits.  Design factors are listed, and the book
elects to begin with an analysis of the required strength factor of the
conduit wall.  The background of corrugated steel conduits is given as
well as specifications in common use; a description of corrugations,
sectional properties, pipe seams, and shapes of conduits; data on struc-
tural plates that are field assembled, and on bolts and nuts, and arch
channels.  The following three principal types of underground conduits
are introduced:   (1) conduits for surface drainage, such as culverts,
storm sewers, and stream enclosures; (2) conduits for subdrainage for
controlling underground water; and  (3) conduits for traffic underpasses,
and service passes.

Design methods discussed in this chapter are based on more than sixty
years satisfactory field experience with buried flexible structures.
The new design approach explained considers overall needs of the drain-
age structure—environment, service demands, and strength requirements
under dead and live loads.  Computer analysis is practical and is an
anticipated future development when sufficient research evaluates the
influence of different soils and compactions on the structure.  The
following topics are treated in the chapter in the same sequence in which
decisions are made in designing buried structures:  (1) computation of
loads;  (2) culvert structural design; (3)- earth backfill design; (4)
foundation preparation; (5) minimum cover;   (6) end treatment; and (7)
maintenance.

difficult service conditions.  The first section deals with inspection
methods and results, including parts on:  destructive forces; methods of
determining durability; laboratory tests; highway culvert inspections;
sewer inspections, air force base drainage inspection; air port drainage;
and levee culverts and sewers.  Section II concerns the influence of
various types of soil and water conditions, and Section III discusses
design for service life, including topics such as:  the amount of durabil-
                                  118

the estimation of runoff from small areas and discusses the rational
method, watershed characteristics, time of  concentration, drainage
area, and the Talbot and Burkli-Ziegler formulas.  The hydraulics of
open drainage channels such as ditches, gutters, and median swales is
treated in the next section.  Section IV discusses the hydraulics of
sewers, including:  design flow of sanitary sewers and of stormwater;
hydraulic considerations for sewers; transitions, bends, and junctions;
pipe friction formulas; values of n_ —  the  roughness coefficient in

Cost  per  year  of  service  depends on durability, maintenance,  ease of
replacement, and  factors  influenced by  local conditions.   Recent  trends
                               119

-------
show an increase in pre-engineered and prefabricated structures with
consequent reduction of on-the-job labor.  This has the following three-
way effect:  (1) promotes factory-controlled quality under more ideal
working conditions; (2) by reducing design and inspection time, it
permits the engineer to concentrate on the whole job rather than its
details; and (3) although product cost may be higher, installed cost is
usually less.  Subsections of this chapter discuss:  (1) price vs. cost;
(2) cost items included; (3) material cost; (4) hauling and handling;
(5) excavation and backfill; (6) installation; (7) replacing the traf-
fic surface; (8) detours, slow orders; (9) supervision, overhead, con-
tingencies insurance;  (10) engineering costs; (11) unstable foundation
conditions; and (12) the cost end of treatment.

 Descriptors:   *Surface runoff,  ^Drainage  systems, ^Controlled drainage,
 *Design  standards, ^Standards,  *Drainage  practices, *Rainfall-runoff
 relationships.
 Identifiers:   *Airport drainage.

 The purpose  of airport drainage is  to remove water which may hinder any
 activity necessary for the  safe and efficient  operation of  the airport.
 Artificial facilities are needed to collect surface runoff, dispose of
 excess groundwater, lower the water table, and protect slopes.  Charac-
 teristics of airport drainage are summarized,  and a list is presented
 of information needed prior to  designing  the drainage system.  Require-
 ments of airport  drainage differ from those of culverts, storm drains,
                                  121

-------
and subdrainage of highways, railways, industrial areas, agricultural,
urban, and suburban areas; and these differences are reviewed, espe-^
cially in regard to rainfall-runoff computations.  Four types of drainage
appearing on airports are mentioned, and Federal Aviation Agency recom-
mended standards are listed.  Remaining sections of the chapter concern
the size of conduits, the selection structures, and storm drains.

The purpose of this drainage manual is to establish standard criteria,
principles, procedures, and practices for the design of storm drainage
facilities within the City of Fort Worth, Texas.  The manual constitutes
the first phase of the development of a master plan for storm drainage
to guide the design and construction of storm sewers and channels in
the City and its anticipated growth area.  The following eight sections
give a logical development to the solution of storm drainage problems.

248
SECTION I, INTRODUCTION; SECTION II, DETERMINATION OF DESIGN DISCHARGE;
SECTION IX, APPENDIX.
In:  Drainage Master Plan for the City of Fort Worth Public Works De-
partment, Storm Drainage Criteria and Design Manual, Knowlton-Ratliff-
English Consulting Engineers, 1967.  19 p.

Descriptors:  *Watersheds, *Time of  concentration,  *Runoff coefficient,
Bibliographies.
Identifiers:  *Glossary, Drainage, Computation forms.

Section I is an introduction explaining the purpose and arrangement of
the manual.  Division of the urban area into defined watersheds, drain-
age areas, and drainage sub-areas and a system of coding these elements
of the drainage system are also presented.  Section II sets forth six
conditions which should govern the design of a storm drainage system.
This section also  treats methods for determining the amounts and rates
of runoff using the Rational Method  and the Unit Hydrograph Method.
The Rational Method is specified for watershed areas up to 1,000 acres.
Above this area, computations using  both methods are specified and the
greater discharge  is to be used for  design of the elements of the sys-
tem.  The use of planimetrictopographic maps of the area is recommended
for determining the size and shape of watersheds.   Runoff coefficients
and graphs of rainfall intensity vs. duration and frequency are included
as being representative of the Fort  Worth area.  A  nomograph for comput-
ing 'time of concentration' is presented.  Section  IX constitutes an
appendix which includes a glossary of terms, bibliography, and forms for
use in making engineering computations.

Descriptors:  *Hydraulic structures.
Identifiers:  *Inlets, Drainage design computations, Computation aids.
                                123

-------
Section III presents information, a nomograph, and curves to facilitate
making computations required in designing the various hydraulic proper-
ties of street gutters and roadway ditches.  The nomograph and curves
greatly simplify the solutions for depth of flow of drainage runoff in
gutters and the lateral spread of the water into traffic lanes.  The
nomograph and figures, which are graphical solutions of Manning's
Equation for uniform flow, are developed for streets of different
widths and roughness coefficients, and for streets with straight cross
slopes and others with various size parabolic crowns.  Section IV
presents sketches, criteria and examples to illustrate design procedures,
standards and techniques for determining hydraulic capacities and
required dimensions of storm drain inlets.  Three major classifications
of inlets are treated; namely, (1) inlets in sumps, (2) inlets on
grade without gutter depression, and (3) inlets on grade with gutter
depression.

 Section V presents criteria, procedures, formulas, and roughness coeffi-
 cients for use in designing the hydraulic elements of storm drains and
 appurtenances to storm drainage systems.  A minimum mean flow velocity
 of 2.5 ft. per sec. is specified, as are minimum grades for various sizes
 of concrete pipe and corrugated metal pipe.  Charts for facilitating
 hydraulic computations based upon the Continuity Equation and Manning
 Formula are included.  Tables of design coefficients are included for
 calculating head losses at inlets, manholes, junctions, bends, obstruc-
 tions and size changes.  The hydraulic grade line is required to be 2 ft.
 or more below ground or streets.  Section VI presents the overall drain-
 age system design procedure, step-by-step, applying the criteria, tech-
 niques, formulas, coefficients, and charts presented in the preceding
 sections of the manual.  Section VII presented procedures for designing
 the hydraulic elements of lined and unlined open channels, rectangular
 and trapezoidal in cross-section, and natural ditches.  The Manning
 Formula is the basis of design.

Section VIII defines the functions of drainage culverts, presents design
criteria, establishes the method of flow determination, and sets forth
design formulas,  coefficients, and procedures for  sizing various types of
culverts.  It is  specified that the quantity of flow shall be determined
by the Rational Method or the Unit Hydrograph Method.  All designs are to
be based on a 50-year storm  frequency.  Formulas are specified for
hydraulic  computations under various culvert flow  depths and various
degrees of submergence at the entrance and  inlet.  Nomographs are
included for use  in simplifying computations associated with the
hydraulic  design  of culverts.

 REPORT  OF COMMISSION TO INQUIRE INTO ALLEGED NUISANCES  IN AUCKLAND
 METROPOLITAN DRAINAGE DISTRICT,
 New Zealand  House of  Representatives,  1965.   32  p.

 Descriptors:  *Sewage treatment,  Evaluation,  Remedies.
 Identifiers:  *New Zealand.

 This report, on the investigation of nuisances caused by midges and
 offensive odors at the Mangere sewage works of the Manukau Sewerage
 Scheme, Auckland, deals with the causes of these nuisances, possible
 methods of elimination, and the necessity for legislation.  Since much
 of  the nuisance is attributable to the sewage reaching the works in a
 stale condition,  it is recommended that the Orakei combined sewerage
 system be cleaned at  least once a year, regular sampling be carried out
 during periods of low flow, provision be made for the injection of
 compressed air at each pumping plant to minimize septic conditions in
 the pressure mains, and the inverted siphons be flushed at least once
 a week during the dry season.  Certain modifications are also recommended
 at  the sewage works,  including the covering of preliminary aeration
 and primary  sedimentation tanks, the use of percolating filters to
                                125

-------
regulate the load on the oxidation ponds, and the reduction of recircu
lation of effluent to increase the period of sedimentation and the
amount of sludge digested.  In view of the increasing population, the
design load of the works for a population of 800,000 will possibly be
reached by 1986; and since the existing oxidation ponds cannot be
extended economically, investigations are necessary to determine the
best process for the extensions.   It is proposed to consider the acti-
vated-sludge process.

MASTER PLANNING FOR STORM RUNOFF FOR NEW NORTH/SOUTH RUNWAY AND ENVIRONS
--STAPLETON INTERNATIONAL AIRPORT,
Wright-McLaughlin Engineers, Denver, Colorado

Report given to the City and County of Denver, Depart of Public Works,
Nov 1969.  39 p.  13 fig, 5 tab.

Descriptors:   *Storm runoff, *Ponding, *Airports, *Detention reservoirs,
*Drainage, *Drainage engineering, *Drainage programs, *Runoff, Pondage,

Identifiers:  *Denver, *Stapleton International Airport, Storm sewers.


This engineering report is unique because it incorporates new and uncon-
ventional concepts in planning drainage facilities for removal of storm-
water runoff.  The master plan for providing storm-water drainage at
Stapleton Airport emphasizes detention and slow discharge of runoff at
outlet points.  Conventional designs usually embody high discharge rates
at outlets which promotes downstream flooding.  The drainage of Stapleton
Airport has been complicated by the construction of a new highway and a
new runway, both of which combined to block overland drainage and dis-
charge to Sand Creek.  In addition, new land development nearby and the
probability of constructing another runway further complicates the
drainage problem.  The engineers propose the development of unconcen-
trated overland flow planes as well as swales and grass-lined open channels
on fiat grades to convey runoff slowly to existing and proposed deten-
tion ponds and outlets.  Rooftop ponding is recommended for new buildings
proposed on and near the airport.  Undersized storm sewers are recommen-
ded to force overland flow during intense storms—thereby reducing dis-
charge rates and downstream flooding.

The manual was written to suggest techniques, methodology, and guidelines
to facilitate the implementation of a new and more thorough approach to
storm drainage problems in Metropolitan Denver.  The authors recomment
adoption of the manual by government agencies in Metropolitan Denver,
and that the Denver Regional Council of Governments provide coordinate
drainage activities.  The following eight chapters are a review of the
most comprehensive treatment of urban storm drainage design criteria
available.

Identifiers:  *Denver, *Storm drainage policy.
This chapter recommends the adoption of this manual by government agen-
cies.  Storm drainage is presented as a 'space-allocation' problem
demanding planning and integration on a regional basis.  A set of policy
statements, based upon underlying principles, technical criteria, and
data is recommended to provide direction for planning, providing, and
operating drainage facilities.  These statements call for the initiation
of flood plain management programs and a program for collecting and
analyzing stormwater runoff and flood data.  Stormwater drainage master
plans, based upon the criteria in this manual and consistent with the
comprehensive plan, are encouraged for adoption by each urbanized drain-
age basin.  Coordination by the Denver Regional Council of Governments
is suggested.  The report includes recommendations for participation by
governmental units in the National Flood Insurance Act of 1968.  Design
criteria discussed relate to storm frequency, initial and major drainage
system considerations, natural drainage-ways, water quality control, and
runoff computation.  Emphasis is placed upon coordinating drainage plan-
ning with transportation and open space planning.

Chapter 2 presents the responsibilities and legal liabilities of munici-
palities relating to planning,  constructing, operating, maintaining, and
repairing drainage improvements.  The importance of obtaining all
pertinent facts and developing  a plan before initiating a proposed
improvement is stressed.  Municipalities proceeding in this manner
can be relatively assured of no legal complications and should be
able to use any of several different means to finance proposed improve-
ments.  Specific legal actions  are cited and briefed.  Chapter 3 cites
drainage systems as being subsystems of the total urban system, affecting
orderly growth and development.  Planning should include consideration
of multiple-uses and additional benefits which can result from well plan-
ned drainage systems.  Emphasis is placed upon adopting plans which incorpo-
rate undisturbed natural swales and waterways.  Other aspects discussed
include drainage management measures, master planning, flood plain planning,
initial and major systems, transportation facilities relationships, open
space, and planning and sizing  storm sewer systems.

The chapter on 'Rainfall' suggests a rainfall analysis technique similar
to that employed by the U.S. Weather Bureau.  The chapter includes
several key rainfall-frequency maps making it possible to determine
any combination of return-period from one to 100 years and durations
from 5 minutes to 24 hours.  Chapter 5 describes in detail the following
three methods of calculating runoff applicable to Metropolitan Denver:
(1) Rational Method, for sewers draining areas less than 200 acres;
(2) Colorado Unit Hydrograph Procedure, for sewers draining basins
in excess of 200 acres; and (3) Statistical Analysis, for streams upon
which future urbanization will have little effect on runoff inflow.
Two statistical methods are illustrated:  (1) Log-Pearson Type III,
and (2) Index Flood.  Flood Plain Information Reports, prepared by the
Corps of Engineers for delimiting flood hazard areas and stream sur-
face profiles, are cited.  Users are urged to allow for anticipated
urbanization.

*Hydraulic design, *Intakes, Design standards, Surface drainage.
Identifiers:  ^Street drainage, ^Street design criteria, *Stprmwater

The chapter on 'Storm Sewers' presents criteria intended for use by engi-
neers in designing systems of storm sewers for collecting and conveying
stormwater runoff to points of discharge in the major drainage system,
including conduits, channels, inlets, bends, junctions, manholes, outlets,
pressure systems, and the related hydrologic aspects of rainfall and
runoff.  Chapter 7 presents criteria and suggested procedures and stand-
ards for street design.  Drainage design of streets  is approached from
the standpoint of providing systems to drain streets and, secondarily,
using streets as integral parts of local drainage systems.  Chapter 8
discusses the various types of inlet devices used for providing openings
to drain stormwater from streets into sewers.   Design criteria and inlet
capacity graphs are treated in detail.  Several examples of typical de-
signs of storm sewers, streets, and stormwater inlets are presented.

This pilot planning study includes:  (1) the development of a methodol-
ogy for the preparation of an area wide storm drainage plan, (2) a study
of alternate solutions to the North Boulder, Colorado major drainage
problems, (3) preparation of storm drainage master plans for five North
Boulder waterways, and (4) development of a financing strategy and a
practical test of the recently completed Urban Storm Drainage Criteria
Manual.  North Boulder was chosen as a pilot study because it represen-
ted most of the urban drainage problems found in the Denver region and
because it had no flood plain management program, policy, or regulation
ordinances.  Field and office studies to develop all practical alter-
nates and to study these alternates using a qualified environmental
design team approach defined the problem.  Economics, comprehensive
plans and programs of the city and county, open space needs, greenbelt
requirements, and legal aspects of urban storm drainage were all taken
into consideration when evaluating alternates.  A detailed discussion
of the Colorado Urban Hydrograph Procedure, which was used in determin-
ing flood magnitudes was given.  The report is contained in two volumes:
Volume one contains the text of the report and Volume two contains thirty
detailed drawings of the proposed Wonderland Creek Drainage.

 The Lancashire River  Authority has  taken over the functions  of the
 former  Lancashire  River Board  in regard to land drainage,  fisheries,
 and pollution prevention;  and  it also exercises new functions relating
 to the  conservation and management  of water resources.   The  annual
 reports  contain sections on all these aspects of the work, and tabulated
 analytical data are appended for various rivers.   In the first report,
 a summary is  given of the features  influencing the quality of water in
 rivers  and streams in the area.  A  map has been prepared indicating the
 general  level of water quality in the various streams.   The  sources of
                                  131

pollution and remedial action are outlined.  Standards for sewage ef-
fluents are based on those of the Royal Commission except in a few
cases where more stringent or extended standards are necessary owing to
local conditions.  Wherever possible, permission is given for discharge
of storm-sewage flows in excess of 3 times the normal flow receiving
complete treatment, with no limitation on BOD and a relaxed standard of
100 mg per litre for suspended solids.  Under certain circumstances
storm flows exceeding about 300 gal per head per day may also be dis-
charged after removal of coarse solids.  The Authority encourages dis-
charge of trade effluents to the sewers, but where this is impossible
the standards applied are similar to those for sewage effluents.  Dis-
charge of effluents to underground strata is discouraged owing to the
possibility of contamination of ground water; however, this is not con-
sidered to include the disposal of small volumes of sewage effluent via
subsurface soakaway systems and this method of disposal is advocated
wherever practicable.  Preliminary work has been undertaken on the water
demands and resources of the area, and a hydrometric scheme has been
prepared.  As an alternative to the Morecambe bay barrage, it has been
suggested that small barrages be constructed at Arnside on the Kent
estuary and Greenodd on the Leven estuary.  Consideration is being given
to the establishment of minimal acceptable flows for the inland waters
and suitable data are being collected.  A technical note is appended to
the second report, describing the operation of dissolved-oxygen recorder
on the River Calder at Whalley.  Information was obtained showing the
effects of climatic and storm conditions on the dissolved-oxygen concen-
tration in the river.  Although the dissolved-oxygen concentration is
usually above 75 per cent saturation, it decreases while the initial
wave of storm runoff is passing downstream.  In the absence of an in-
creased runoff from the Ribble catchment to compensate, conditions harm-
ful to migratory fish might occur in the Ribble below the Calder conflu-
ence .

Effluents from sewage works of the North Shore Sanitary District, Lake
County, Illinois, will be discharged into the Des Plaines river instead
of into Lake Michigan, thus reducing pollution of the lake.  Those
works giving primary treatment only will be abandoned, and their services
absorbed in expansion programs of other works.  The capacity for storm
sewage flows is to be increased, so that storm sewage will not enter the
lake but will be pumped to works for treatment after the storm.

areas greater than 300 acres  is presented.  The complete physical character-
istics of the drainage structures and the intervening reaches of their
streams are given.  A method  is developed for determining flood flows.
Flow quantities to be considered for design purposes are established,
as well as indications for improvement of inadequate flows.  The study
provides accurate information about present and future flood hazards,
their location and extent; the erosion and siltation problems; and open
space needs.  Provided are suggestions for subdivision regulations for
the enabling and enforcing of protective measures.  Guidelines for leg-
islation necessary for carrying out any plans selected by decision
makers are supplied.  Suggestions for the financing and administering
of public improvement programs are also made.

The present-day Johannesburg waste water scheme is described along with
long-term planning needs for expansion of water resources systems.  Pop-
ulation forecasts are used in considering water usage and its effect on
sewer flows.  Present problems of outfall sewer designs are discussed
including the imperfect separation of storm and sewage flows and the
obsolence of outfall sewers due to overload from combined sewage and
storm overflows.  The capacity of existing treatment works is also
considered as well as developments in treatment technology and recommen-
dations for the enlargement of sewers to meet future demands.  Financial
implications of the development plans are included.

A detailed report on capital and  operational costs  with data for 79
works situated in areas of  England, Scotland, and Wales, all of which
were commissioned after 1952, is  presented.   Graphs of costs in relation
to specific problems are shown as well  as cost analysis charts.  Some
works had a record of the total flow entering the works in various time
periods, but few were able  to differentiate  between the flows receiving
full treatment and those diverted to storm treatment.   Because of the
lack of reliable flow data, operating cost data  is  presented on a
population basis.

Rohnert Park, Sonoma County, and  the  Sonoma  County Flood  Control District
have developed  a new method of  financing major  drainage channels.
One channel, which  served  as a  major  drainage facility to accomodate
storm flows  from the anticipated  high density development area, could
not be improved because  of costs.  A  policy  requiring land developers
to improve  all  major drainage ways was adopted  and the problem was
solved.  A  large drainage  area  plan is discussed  along with problems
of financing its improvements.

 separation.
 Identifiers: *Construction  grants, ^Combined sewers, ^Viewpoint.
 The author criticizes the FWPCA's new policy of refusing construction
 grants for projects that provide less than 85% removal of five-day  BOD,
 because this requirement does not cover the oxygen demand of  ammonia
 (derived from human urine) or of combined sewer overflows.  This  policy
 would eliminate aid to most communities since many areas have combined
 sewer overflows.   Big cities are cited as having the worst  water  pollution
 problems because they utilize storm drains as combined sewers,  and  street
 congestion hinders sewer separation.  Chicago's alternate solution  of
 underground deep rock storage tunnels for sewage is described and praised.
 The following recommendations are made towards achieving pollution
 abatement:  (1) authorization for grants-in-aid to solve combined sewer
 problems; (2) mandatory heavy chlorination of sanitary sewage;  (3)  water
 pollution control authorities to manage watersheds; and (4) FWPCA's
 promotion of further legislation required to carry out the  above  aims.

County, Pennsylvania.

The Plan is a proposal for the wise use of the water and land resources
of the Upper East Branch of Brandywine Creek, Chester Co., Pa.  The Plan
was developed for the Chester Co.  Water Resources Authority by the Insti-
tute for Environmental Studies, University of Penna; Regional Science
Research Inst.;  United States Geological Survey; and their consultants.
The aim of the Plan is to prevent  deterioration of the water resources
and thus to retain the amenities of related land when urbanization occurs
in the Brandywine watershed.  The  Plan recommends 3 types of action; pub-
lic purchase of  conservation easements or other less than fee interests
on flood plains, stream and swale buffers, steep slopes, and forests; devel-
opment and adoption of detailed water supply and sewage disposal plans in
advance of urbanization; and enactment of strong local regulations for
erosion and storm runoff control.

Identifiers:  *Volume-time distribution.

This paper's purpose is to explain the complex processes involved in
finding the volume and time distribution of runoff; two factors basic
to the study of the rainfall-runoff relationship.  Illustrations of the
role of various basic hydrologic processes are made using digital synthe-
sis models (Standford Watershed Model IV).  A schematic description of a
watershed, presented in the first section, provides background for con-
cepts and terms which follow.  The second section discusses volume of
runoff, and the third illustrates timing and runoff distribution.  The
conclusion comments on education in the response of watersheds to rain-
fall and on the application of synthesis methods of investigation to
water resources studies in general.  (See abstract number 292).

The two types of sedimentation data are associated with:  1) gross drain-
age basin sediment yield; and, 2) time variability of sediment yield.  For
a given basin, the greater the forested area the smaller the sediment
yield, and the effects of urbanization may influence the base condition
of a given area.  Geomorphic changes may be induced by the increased
variability of flow caused by urbanization and highway construction.

Descriptors:  ^Separation  techniques,  *Grants,  *Pollution abatement,
Overflow.
Identifiers:  *Abatement facilities, *Combined  sewers, *Policy change.

The  article  cites the  federal  government's neglect of big city's water
pollution  abatement  needs.  Recommended  are  federal grants for construc-
tion of combined sewer overflow  abatement facilities, since this pollu-
tion problem is not  solved  by  installation of wastewater treatment
plants.  Either sewer  separation or stormflow storage is needed before
treatment, and such  projects are not now eligible for federal grants.
Other suggestions include:   (1)  authorization of incentive grants for
new  big-city projects  until recipients receive  the level of federal
support they deserved  since 1956;  (2)  making federal grant committments
reliable and adequate  as to dollars;  (3) strengthening the market for
local bonds  by renouncing  abortive efforts to tax municipal bonds;
 (4)  implementation of  regulatory standards encouraging towns to correct
their worst  problems and to achieve the  most pollution abatement for
each federal and local tax dollar; and (5) encouraging local use of sewer
service by offering  a  federal  grant incentive,  but prohibit an industry
from destroying any  stream for a fee.

Stormwater overflows from combined sewerage systems and from industrial
wastes is  the principal cause of river pollution in the Boston area.
About  100  outlets into the Harbor and its tributaries are affected by
Boston storm overflows and combined sewer discharges from neighboring
communities.  Four principal alternative methods of pollution abatement
for the area are:  1) complete separation-of all sanitary sewerage and
storm drainage systems, 2) construction of chlorination detention tanks,
3) construction  of surface holding tanks, and 4) implementation of the
deep tunnel plan.  Engineers recommend the construction of sanitary
sewers and storm conduits wherever existing principal design flows or
runoff from 15-year frequency design rainstorms.  The governmental
agencies responsible for pollution control, as well as various studi'es
and approaches to alleviation and abatement methods are listed.  Results
indicated  that the most positive method of collecting and disposing
overflows  of mixed sewage and Stormwater is the deep tunnel plan.

 Identifiers:  *Urban drainage.

 This section describes the nature of pollution, some dimensions on
 quality,  the current status of water renovation, and research needs.
 Considerable background information is provided.  Types of pollution
 discussed are:  disease-causing pollution, and conservative and non-
                                 138

conservative pollution.  Factors which influence water quality are
examined, namely:  usage, natural pollution, agricultural and urban
drainage, waste-solids disposal practices, recreation, and certain
political implementations.  The following are areas related to water
quality which need the most research:  improvement of treatment processes,
translation of theory to design, optimization of water quality management,
development of stream use criteria, groundwater quality management, and
improvement of marine disposal systems.   (See abstract number 292).

Sanitation problems  of  communities  in Northern Canada are discussed, and
some environmental conditions  are evaluated.  Improvements in sanitation
in small  Canadian communities  by providing piped water and sewage ser-
vices have been  proposed.  Two original, relatively inexpensive, all-
weather systems  suitable where pipes may not be buried on account of
soil conditions  are  described.  Ideas and suggestions for planning water

 Descriptors:   *Rainfall intensity,  *Storm  drains, Hydraulic design, Roads.
 Identifiers:   *Stormwater  inlets.

 Factors to be considered in  designing stormwater inlets  for roads are
 discussed utilizing  hydraulic  requirements rather than a purely empirical
 viewpoint.   Rainfall intensity is  one determining factor since, theoreti-
 cally, rainfall intensity  is a function of the  area  to be drained.  The
 intensity of  rainfall and  the  period for which  it lasts  varies across
 the country,  and therefore,  this factor must  be carefully evaluated before
 designing stormwater inlets.

International Textbook Company, Scranton, Pa., 1960.  513 p.

Descriptors:  *Water supply, *Waste disposal, *Sanitary engineering,
*Design, *0perations, *Industrial wastes, *Water treatment.

This volume presents the theory and practices relating to the interre-
lationship between the basic problems of water supply and waste disposal.
The authors provide an integrated treatment of the fundamentals common to
both of these areas of sanitary engineering.  Detailed are the design and
operation of systems for water supply and waste disposal.  Problems in
water supply caused by over-population and expansion plus unusual disposal
dilemmas created by increased amounts of industrial waste products are
described, and some solutions are proposed.  The first nine chapters
concern basic principles of water supply and waste disposal including:
water use and sewerage volume, piping for water and sewage systems, and
the collection and storage of water.  The last fourteen chapters relate
to either problems or solutions such as:  water treatment by screening and
sedimentation; control of corrosiveness, taste, and odor; sludge treatment
and disposal; filtration and disinfection of water; removal of dissolved
minerals from water; the activated sludge process;  and primary and
secondary sewage treatment.

method for measuring streamflow.  Other sections discuss the estimation
of watershed yield, empirical  formulas for runoff of water supply,
an investigation of the source for yield, and the quality of surface
water.  Rainfall-runoff proportions, along with rainfall rate and
duration, are cited as important criteria for designing storm drainage
facilities.  Techniques for computing these three elements are given
including the Rational Method  and the Burkli Zeiger empirical formula
for determining runoff.  Other topics treated in the chapter include:
percolation and absorption, evaporation, and groundwater.  (See abstract

Identifiers:  ^Agricultural  land runoff,  Combined sewers.

The author discusses sources and effects  of pollution in the lower
Missouri and Mississippi Rivers, and explains his reasons for opposing
secondary treatment and storm sewer separation for this area.  He states
that sufficient pollution abatement has already taken place in these
rivers and that communities  need not waste tax dollars supporting federal
grants for further  pollution prevention facilities.  According to Mr.
Hopkins, the Missouri River  can assimilate wastes properly with the
treatment that is presently  offered.  He  also asserts that sewered wastes,
municipal and industrial, and combined sewer overflows cause far less
pollution to the  rivers than does surface runoff from agricultural lands
upstream.  Cost of  sewer separation for this area is estimated to exceed
$250 million.

This research project was conducted to determine the effect of salt
applications to de-ice highways on the sodium and chloride levels in
1) streams and rivers, 2) private water supplies contiguous to highways,
and 3) soils bordering highways.  Analysis of seven rivers in Maine
from six samplings over a two-year period indicate that sodium and
chloride concentrations are not affected by highway salting, since the
level of both ions remained consistent throughout the period.  Although
the concentrations of both ions tended to increase from the headwaters
to the mouth of the rivers the average concentrations for 27 sites were
3.4 and 1.5 ppm for sodium and chloride respectively.  Semi-annual
analyses of 100 randomly selected wells along Maine highways indicate
that levels of sodium and chloride are much higher than normal, averaging
69 and 162 ppm respectively.  25% of the wells were unfit for potable
supplies because they contained in excess of 250 ppm of chloride.  Sodium
and chloride levels in soils contiguous to highways bear a direct relation-
ship to the length of time over which highways have been salted.  In areas
where salt has been applied for 20 years the sodium levels have risen
over a distance of 60 feet from the edge of the highway, and to a depth
                                 144

-------
of 18 inches.  Sodium saturation of the soil approaches 15% at some sites,
and chloride levels in the soil-water system ranged from 10 to 2525 ppm,
thereby producing the equivalent of an "alkali" condition.

Linear models were developed and used to study the  significant  factors
controlling costs of conventional urban drainage systems.  The  objective
of the study was to  find decision making tools which  engineers  and
planners could employ for estimating the cost of alternative  sizes  of
drainage facilities  and the degree of protection to be afforded;  and for
judging the potential for development.  Techniques  of factor, component,
and non-linear analysis were performed with data collected from 100
municipal agencies around the country.  The study revealed that design
practices as well as geographic areas were important.  Physical features,
although most important, were usually the fixed, uncontrollable variables.
Design factors,  on the other hand, were important in both degree and kind.
The analysis explained the differences in the design methods  and led to
the development  of equations to predict the cost for various  levels of
design.

program capable  of  "representing urban  stormwater runoff phenomena,
both quantity  and quality, from  the onset of precipitation on the basin,
through collection, conveyance  (both  combined and separate systems),
storage, and treatment systems to  points downstream from outfalls which
are significantly affected by storm discharges".  The  program is intended
for use by municipalities, government agencies,  and consultants as  a
tool for evaluating the pollution potential of existing systems, present
and future, and  for comparing alternate courses  of remedial action.

Public Works, Vol 100, No 6, pp 79-82, Jun 1969.

Descriptors:  *Pollution abatement, Storm runoff, Sewage treatment,
Separation techniques.
Identifiers:  *Lake Erie, *Water quality programs, Combined sewers.

Sources and effects of pollutants in Lake Erie are described along with
plans and recommendations for the elimination of pollution from the
lake.  Urban runoff and combined sewer overflows are major sources of
pollution contributing BOD, bacteria,  and nutrients — especially phospho-
rus.  Detroit, Cleveland, and Toledo are the largest offenders in the
area of storm water runoff.  Suggested state water quality programs are
outlined in addition to areas requiring research and development such
as:  tertiary treatment, nutrient removal, sediment evaluation, pesticide
pollution, radioactive and thermal pollution, industrial sludge disposal,
oxygen deficient zones, and eutrophication.  Expensive separate sewerage
systems are recommended only where feasible, such as in redevelopment
projects.  However, where combined sewers exist, overflows should be
disinfected before being discharged to a body of water, and future
plans for storage and treatment should be made,

Descriptors:  ^Foreign research, Estuaries, Waste water treatment.
Identifiers:  *Chao Phraya River, Thailand.

Programmed sampling and tests of the Chao Phraya River Estuary show
that its pollution-receiving capacity is limited.  No sewage collection
system presently exists in Bankgok, but separate wastewater and storm-
water systems are being planned because a combined system would undoubtedly
cause further pollution of the estuary during severe rainfall.  More
studies must be made before the degree of oxidation of organic carbon,
nitrogen, and amoniacal nitrogen can be accurately determined.  Further
studies are also being conducted to decide upon the necessary type of
initial wastewater treatment.  Such treatment must include sufficient
oxidation of organic carbonaceous substances and oxidizable nitrogenous
substances.  This study also demonstrates the need for modifications in
standard BOD measurements in addition to modifications of the parameters
and equations defining DO concentrations for tropical estuaries.

*Hydrology, *Water pollution control, ^Digital computers, *Water manage-
ment  (applied), *Engineering education, Water utilization.
Identifiers:  *Textbook.

This book is basically aimed towards introducing water resources
engineering to the undergraduate civil engineering student.  The first
five  chapters present hydrology, the subject basic to water management.
Chapter six involves legal  aspects of water use which often constrain
planning efforts.  Chapters seven through twelve discuss physical works—
dams, canals, pipelines, etc.—which are utilized in almost all types of
water resources projects.   Chapters fourteen through twenty cover prin-
cipal water use£, and the last chapter summarizes the planning procedure
for single and multi-purpose projects.  Pollution control is stressed in
regard to waste treatment,  and the role of the digital computer in
hydraulic engineering is thoroughly discussed.

The open channel and the pressure conduit are the two types of conduits
that convey water.  The open channel may take the form of a canal,
flume, tunnel, or partly filled pipe, all of which are referred to in
this chapter.  Open channels are characterized by a free water surface,
in contrast to pressure conduits which flow full.  This chapter details
salient features of the hydraulics of open-channel flow including:
uniform and nonuniform flow, normal and critical depth, location of the
hydraulic jump, free outfall, hydraulic efficiency of channels, channel
transitions, and flow around bends and steep slopes.  Measurement of flow
in open channels is also explained for weirs and venturi flumes. Canals,
canal  appurtenances, and tunnels are described in the section on types
of open channels.

Descriptors:   ^Pressure conduits, ^Hydraulic properties, *Flow measure-
ment,  Construction materials, Construction equipment.
Identifiers:   ^Pollution potential.

A pressure  conduit flows full and is often less  costly than an open
channel because it generally follows a shorter route.  If water is
scarce, pressure  conduits may be used to avoid water loss by seepage and
evaporation that  might occur in open channels.   Pressure conduits are
preferable  for  public water  supplies because of  the reduced opportunity
for  pollution.  This chapter is limited to turbulent flow in pipes, since
this  is what  the  hydraulics  engineer deals with  exclusively.  Topics
covered under  the section on the hydraulics of pressure conduits include:
head  loss due  to  pipe friction, minor losses in  pipelines, flow with
negative pressure, flow in branching and parallel pipes, and pipe
networks.   Other  sections discuss:  measurement  of flow in pressure
conduits; forces  acting on pipes; materials such as steel, cast-iron,
and  concrete  for  pressure conduits; appurtenances for pressure conduits
such  as gates, valves, and surge tanks; and inverted siphons.

Identifiers:  *Stormwater disposal, ^Highway drainage.

The problems of drainage may be subdivided into municipal drainage, the
disposal of excess stormwater from cities; land drainage, the disposal
of stormwater from rural areas, and the removal of excess water from
the soil; and highway drainage, the disposal of stormwater from highway
rights of way.  Principles governing most drainage projects are basically
the same, but the differing physical problems encountered require different
solutions.  In describing procedures for designing storm drainage works,
topics covered include:  estimates of flow, gutters, inlets, grated and
curb-opening inlets, manholes, and outlet works.  The section on land
drainage discusses:  drainage ditches, underdrains, groundwater flow to
drains, layout of a tile-drain system, drainage by vertical wells, and
legal aspects of drainage.  Topics included under highway drainage are:
longitudinal and cross  drainage,  culverts, culvert inlets and outlets,
debris barriers, culvert hydraulics, bridge waterways, and dips.

This paper describes the damage to the sewer and storm drain systems  in
the City of Los Angeles during and subsequent to the winter rains of
January and February, 1969.  Emergency repair work, performed by forces
of the Bureau of Sanitation of the Department of Public Works under
adverse conditions, resulted in the protection of public and private
property from costly damages.  Steps taken to insure the health and
sanitary condition of the citizenry included restoration of sewer lines,
repair to channels and debris basins, and alleviation of slide potential.
Damage was also experienced on a county-wide basis and a summary of
events shows the interrelationships involved in emergency repair work
performed.

 Solutions  to land  erosion  and  drainage  problems  caused by  suburban  sprawl
 in a Nebraska  conservation district are outlined.   Increased paving,
 roofing,  and  compacted soils  result in  erosion and flooding; therefore,
 the construction of major  and  minor storm drainage and water runoff
 systems  is recommended.  An Omaha program to reduce sedimentation from
 developing areas is detailed  in addition to guidelines for good land

 This paper contains results taken from a detailed engineering investigation
 and comprehensive technical study to evaluate the pollutional effects from
 combined sewer overflows on the Sandusky River at Bucyrus, Ohio which
                                 153

-------
evaluated the benefits, economics, and feasibility of alternate plans
for pollution abatement from the combined sewer overflows.  A year long
detailed sampling and laboratory analysis program was conducted on the
combined sewer overflows in which the overflows were measured and sampled
at 3 locations comprising 64% of the city's sewered area and the river
flow was measured and sampled above and below Bucyrus.   The results of
the study showed that the combined sewers will overflow about 73 times
each year discharging an estimated annual volume of 350 million gallons
containing 350,000 pounds of BOD and 1,400,000 pounds of suspended solids.
A method of controlling the pollution from combined sewer overflows is
presented along with the degree of protection, advantages, disadvantages,
and estimate of cost.

Chicago is planning an underflow sewer system consisting of a large
tunnel under rivers and canals into which all combined sewers will dis-
charge.  This system, costing $400 million dollars,  will eliminate the
need for a $4 billion dollar conventional separate sewer because spillages
from combined sewers will be directed to the underground tunnel rather
than polluting surface streams.   The performance of  the Lawrence Ave.
underflow sewers was analyzed through a computer simulation of the
system.  Untreated overflow into local streams was reduced from 3%/year
of the sewage from combined sewers to .8% from Lawrence Ave.'s underflow
sewers.

This paper examines the complex technical, legal, and administrative
problems involved in northeastern Illinois' water situation and the high
degree of use and reuse taking place in this area.  Even stormwater
runoff along with its pollutants is retained in reservoirs to be used
later beneficially.  Existing problems related to stormwater runoff in
this area include the restriction of water infiltration and, thus, the
production of increased runoff caused by the construction of impermeable
surfaces (roof tops, streets, and parking lots), and the maintenance of
unsightly stormwater basins in areas where water recreational facilities
are needed.

Identifiers:  Combined sewers, Storm sewers.

This digest of  information on sewerage systems includes definitions,
explanations, and tabular data on a wide range of  topics such  as:
sewer type classifications, considerations in sewer design,  sanitary
sewers,  sewer hydraulics, storm  and combined sewers, sewer  appurte-
nances,  and inplant piping systems.  Conditions  are enumerated under which
sanitary sewers, combined sewers, or separate sewers should  be installed.
Storm sewers are recommended to  relieve loads on existing combined
sewers.  Stormwater treatment is suggested unless  an alternative  can
be  employed such as sanitary wastes transport under pressure through
small lines laid in existing combined sewers.  The planning  and design
of  storm and combined sewers is  described including correct  location
and design capacity of such systems.  Appurtenances relating to storm-
water runoff, such as overflows  and storm tanks, are defined and  de-
scribed.  Storm tanks are more commonly used in  combined systems  in or-
der that stormwater eventually be passed to sewage treatment works to
avoid overflow  of storm water into nearby bodies of water.   Such  tanks
operate  under gravity or pumping conditions.  Tables,  diagrams, and
graphs in the digest include:  sewer classification, sewer  system
layouts, population trends in the U.S., quantities of  water  and sewage
flow in  U.S. cities, amounts of  hourly and daily sewage flow in a sample
city, extreme flow rates as a function of population,  filtration  speci-
fications, rates of flow using Bernoulli's, Manning's, and  Hanzen-Wil-
liams' formulas, a sewer design  slide rule, sewer  hydraulic  information,
recommended minimum sewer grades, and design  criteria  for sewer appur-

Recommendations are made regarding the sewerage and drainage problem.
The desirable solution of the sewerage and drainage problem should
include the following action:   (1) convey spent water quickly by
underground conduits to the place of treatment and disposal; (2) avoid
combined sewers, if possible;  (3) design so as to conserve and utilize
energy of flow to achieve economy of construction cost;  (4) detain storm-
water near the origin, where possible; (5) interpret river gagings with
a critical eye;  (6) find out what flow-ways we need, establish and main-
tain them; and (7) have a master plan.  Included in the paper are:  a
formal comment, a discussion, and a workshop regarding the subject matter.

RIVER CONSERVATION AND WATER CONSERVATION WORKS:  CHAPTER 9 - THE USE
OF BALANCING RESERVOIRS AND FLOW REGULATING RESERVOIRS IN DEALING WITH
RUN-OFFS FROM URBAN AREAS,

Descriptors:  *Surface drainage, *Flow control, ^Regulated flow, *River
systems, *Design criteria, Sewers.
Identifiers:  *Urban runoff, *Flow balancing.

This chapter attacks the problem of increased runoff from a river caused
by urban development and the installation of surface water drainage.
Such a problem ensues wherever more paved areas are directly connected
by sewers to a river.  As a solution, the author recommends flow balancing,
which entails passing the flow through a natural or artificial lake
with a restricted outflow, or flow regulation, in which part of the river
flow is passed into specially-prepared areas.  These plans can be economi-
cal, and they reduce peak flows and also channel sizes farther downstream.
General design factors for implementing flow balancing and regulation
are discussed; and then a scheme combining the two principles, which was
                              157

-------
applied to the River Cray, is described.  Flow balancing is possible in
new or undeveloped towns; whereas, it cannot usually be implemented in a
built-up area unless, lakes or disused mine workings are available.  In
such urban areas, flow regulation is readily applicable.  (See abstract
number 316).

 Identifiers:  *Interviews, Radcliff, Kentucky, Storage-grinder pump.

 Installation  of a  storage-grinder  pump  unit in every  home raises questions
 regarding:  allocation of costs  of  the  units; responsibility for mal-
 function  of the units; arrangements  for service of  the units; and wil-
 lingness  of owners  to accept  the presence of units  in their buildings.
 Twenty-five householders in Radcliff, Kentucky, whose houses are served
 by sewage ejector  units  were  interviewed  to obtain  opinions about fea-
 tures  of  the  units  that  appeared to  represent potential sources of
 nuisance, inconvenience,  or other  liabilities.  Also  interviewed were
 the  superintendent  of the utility  operating the Radcliff sewerage
 system, owners of  five houses  in Louisville, Kentucky, at which sewage
 sampling  stations were located,  and  three consulting  engineering firms
 who  have  considered schemes involving the installation of sewage pump-
 ing  equipment on private properties.  Opinions and  practices reported
 reflect the view that sewage  pumping equipment placed on private pro-
 perty  as  part of a  public project  should  be purchased, installed, and
 serviced  at public  expense.

Identifiers:  *Viewpoint, *Great Britain.

The author states that Britain's shortcomings with regard to water
pollution control stem from a failure of financial investments in
control plants to keep pace with the changing technology of industrial
processes and their effects on both domestic ,and mixed-municipal sewage.
A comparative cost analysis between Britain and the United States
concerning water pollution control is discussed including:  cost per-
cents appropriated for equipment, industrial waste treatment, municipal
sewage treatment, and river pollution abatement,  Basic purification
standards are included as well as effluent standards.  The author expands
on the idea that the exportation of pollution control equipment such as
instrumentation and control systems to the United States is one area
in which the British may contribute their technological advances in
aiding both the United States and Britain.

The Department of Housing and Urban Development recently granted funds
to the Los Angeles County Flood Control District for the construction
of a storm drainage system.  Such a system will eliminate problems
caused by accumulated stormwater sumps along the undulating terrain of
the area.  Such stormwater accumulations have caused drownings and
mosquito proliferation, and they sometimes overflow and flood surrounding
areas or infiltrate the sewer system creating a health hazard.  The
project consists of a tunnel connecting storm drains to the Pacific Ocean.
The new drainage system will encourage redevelopment in the area by
resolving the problems presently making the region an unattractive and
often-dangerous place to live.

Engineering elements essential to the financing, construction, operation
and maintenance of sewerage facilities for use by two or more parties
are outlined.  Contract terms, conditions and clauses in successful use
which include the engineering basis for jointly sharing the capacities
of sewage collection and treatment facilities, and for joint sharing
of capital and annual operating and maintenance costs are covered.
Definitions of engineering terms; regulations pertaining to conditions
of wastewaters, both domestic and industrial, acceptable from the party
being served; specific stipulations considered typical for excluding
discharge of detrimental wastewaters and sewage which contains stormwater;
drainage from stormwater inlets, floor drains, and from other direct
sources; and how and when payments are made according to actual contracts
in effect are given.  The importance of scheduling payments to meet
commitments is presented.  Examples are cited to indicate how engineer-
ing factors and needs of a specific location affect the patterns of
a contract.  The fact that no lawyer should endeavor to write a contract
without engineering consultation and that no engineer should write a
contract without legal advice is emphasized.

The setting up of a central body, with much wider responsibilities than
those of the present Water Resources Board, to plan, initiate, or coor-
dinate action over the whole field of water resources and sewage purifi-
cation and disposal, is proposed by the Institution of Municipal Engi-
neers.  The following points were discussed:  the inadequacy of the
present form of organization for the future; water supply and effluent
disposal planning; standards research; and the delegation and deter-
mination in regards to responsibilities of river boards and local gov-
ernment bodies (i.e. surface water sewerage, positioning of surface
water overflows and outfalls).

The Mersey and Weaver River Authority defined effluent standards in
accordance with relevant local conditions.   Standards were developed for
the following areas:  (1) purified sewage effluents discharged to inland
rivers (normally applied to rates of flow up to 3 d.w.f.); (2) partially
treated sewage effluents discharged to rivers (normally applied to rates
of flow in excess of 3 d.w.f.); (3) untreated sewage effluents from
storm sewage overflows; (4) sewage effluents discharged to tidal waters;
and (5) trade effluents.

Plaintiff owned a mill adjacent to a non-navigable creek.   The creek
flowed through a culvert under defendant's tracks approximately two
thousand feet from the mill.  The culvert was adequate in area to take
care of the normal flow of the creek.   The defendant raised its tracks
two and one-half feet, and reinforced the culvert by adding several
inches of new masonry, thereby reducing the flow of water through the
culvert by about fifteen percent.   The raising of the tracks prevented
the overflow of the water in time of heavy rains.  During such rains,
plaintiff's mill and cotton gin were damaged because of flooding.  The
question presented was whether damage resulted from an act of God or
through the fault of the railroad.  The court held that this was a
question for the jury.  If the flood that did occur was so extraordinary
and unprecedented that it could not have  been foreseen and the damage
could not have been prevented by prudential means ,  the railroad could
not be held liable.

Plaintiff brought action to recover for damages resulting from defendant
city's maintenance of a nuisance.   The alleged  nuisance consisted of a
sewer beneath plaintiff's land which lacked the capacity to handle in-
creased surface runoff.  Judgment was entered  for  the  plaintiff and city

appealed.  The reviewing court affirmed the lower court, holding that
the evidence presented by the plaintiff was sufficient to establish:
(1) that plaintiff's premises became flooded even during normal rain due
to the inadequate capacity of the sewer, (2) that the paving of a nearby
highway greatly increased the runoff into the sewer in question; and
that (3) the city was guilty of maintaining a nuisance by failure to
enlarge the sewer system after notification by plaintiff of the increased
flowage into the sewer.

The authority of sanitary districts includes jurisdiction over drainage,
sewage, and treatment works within their respective territories.  Dis-
tricts are charged with prevention and abatement of pollution by estab-
lishing standards, requiring permits for construction of municipal
sewage systems and for changed systems, and initiating court action against
violators.  Financing of projects may be through sale of bonds.  Authority
of districts includes building docks, highways, bridges, approaches, and
other works related to drainage canals and channels, and existing water-
ways may be improved to facilitate drainage.  Districts have the power of
eminent domain in most instances and are held liable for all damage caused
by improvements.  Specifications are made  for size and capacity of sewage
and drainage watercourses, for restrictions on the type of sewage discharge
allowed, and for connecting facilities between districts.  Districts which
violate the act are subject to court action initiated by the Attorney Gen-
eral.  Municipalities are required to share water sources that have been
saved from pollution with other cities.  There is provision for inspection
of new channels.  The city of Chicago is organized as a drainage district,
and the statutory powers are conferred on  the corporate authorities.

The board of trustees of any sanitary district is responsible for the
collection and disposal of sewage within their area and must protect the
water supplied to their inhabitants from contamination.   They may use
such conduits, pipes and pumps as are necessary to construct an adequate
sewage system for this purpose.   They must also treat and purify all
sewage before allowing same to flow into any lake, river or other water
course.  While real and personal property may be taken for the district's
corporate purposes, whether by purchase or condemnation, adequate com-
pensation must be paid therefore either by gross sum or annual rental.
The district's sewers may pass along or under public roads or public
ground and may have conduits and pipes laid under public waters, but in
either case not in such a manner as to impede normal use thereof.  A
district has the power to keep its water courses free from pollution and
may construct dams and remove debris from same in the interests of public
health.  The board may finance costs of such a system either through
general taxation or special assessment.

The Department of Public Works and Buildings is responsible for making
a survey and preparation of a master plan for drainage and flood control
of all watershed areas of this state so that hazards to persons and prop-
erty may be reduced.  Such a plan includes the full hydrography of each
watershed area including rainfall, runoff, frequency and severity of
floods.  A drainage district may construct a sewage disposal system to
eliminate sewage which is a menace to public health.  Such a system may
be financed through assessments on the lands benefitted.  Revenue bonds
may be used to pay the initial costs of such construction, to be repaid
solely from the revenue from the operation of such system.  The Depart-
ment is responsible for general coordination and supervision of the
efforts of the individual districts.  It may also enter agreements with
the federal and local governments for the formulation of plans, including
funding, and for the construction, operation and maintenance of improve-
ments for flood control, drainage and utilization of water and water
resources.

 Plaintiff,  a non-profit  corporation, sued  to enjoin  defendant from further
 using a sanitary sewer bypass which allegedly caused sewage to flow into
 a private lake.  The  lake was used by area residents for all household
 purposes.   The by-pass  is part of the city's combined storm sewer and
 sanitary  sewer system.  When the level  in  the sanitary sewer reaches a
 certain height at  the point  of a bypass because  of a stoppage or an over-
 loading caused by  heavy  rain, the sanitary sewer overflows into the storm
 sewer.  At  one particular by-pass, the  storm sewer empties into a natural
 watercourse or ditch  which,  in turn, empties into plaintiff's lake.  The
 injunction  was denied, because plaintiff had not demonstrated actual and
 substantial injury.   The  court held that speculative or anticipated damage,
 as shown  in the  instant case by  plaintiff,  is not properly the subject of
 a permanent injunction proceeding brought  by individuals.  While plaintiff
 had shown that the defendant had created a condition whereby diluted sewage
 could, on infrequent  occasions,  flow into  plaintiff's lake, there was no
 actual evidence  of pollution.  The court concluded that pollution control
 and abatement  are  best left  to the appropriate specialized state agency,
 except in cases  of flagrant  and  obvious polltuion.

Brown, a subdivision developer, sued to require the city of Joliet,
Illinois to record her subdivision plat.  Her plat had been down by the
city planning commission and subsequently the city council because they
felt she had failed to include adequate plans for surface runoff.  The
planning commission felt that development without adequate provision for
storm drains would increase drainage problems in adjacent areas and
would not drain her own development properly.  Brown claimed that the
requirement of more adequate provision for surface runoff was an illegal
confiscation of her property.  Judgment was entered for the city.  The
city had authority to make regulations for adequate water drainage before
recording of a plat.   There is a presumption of validity of these ordi-
nances.  There was sufficient evidence to show that Brown had not made
adequate provision for surface drainage and that the city had acted
properly under the ordinances.  Brown was not deprived of property un-
constitutionally as the problem required by the city to be remedied was
a product of her own specific and unique activity.   The problem was not
one of the general community which the city is trying to force her to
remedy at her own expense.

surface and percolating water from the catch basins to the rear of the
property.  The city furnished the pipes for the drain.  Subsequent
owners, including plaintiffs, allowed the drain to remain.  Plaintiff
sought a mandatory injunction requiring removal of the drains and a
damage award for flood damage due to faulty drainage.  The court held
that defendant had a right to build the catch basins in order to keep
the street in repair and safe for travel and that it would not be liable
for any water therefrom which floods nearby land.  Adjoining landowners
may erect drains to prevent flooding of their land, but the city is not
responsible for negligent construction thereof because the drain is in

A statute authorized the county drain commissioner to construct drains,
and listed in its definition of 'drain1 the term, "any sewer.'  The com-
missioner proceeded with the planning and financing for a sanitary sewer
for an area within the county.  The commissioner stopped the proceedings
until the legal question of whether he had authority to construct this
sewer could be determined.  The problem concerned the definition of
'drain' under the statute, and specifically, whether it included the
system designed solely as a sanitary sewer,  completely closed to surface
or storm water drainage.  Interested property owners filed application
for a writ of mandamus to direct the commission to install the sewer.
The court issued the writ, ruling that there was nothing in the language
of the statute to preclude the commissioner from installing this particu-

Plaintiff brought this action for damages alleged to have been caused by
the overflow of surface and sewage  waters onto and across his premises.
The evidence indicated that plaintiff's property was directly in the path
of the natural flow of surface water in the area but that the city had
installed a storm drain channeling  the surface runoff into a ditch running
toward plaintiff's property and directly above the city's sanitary sewer
line.  The result of maintenance of these tandem ditches was  to increase
the pressure in the sewer pipes by  the infiltration of surface water from
the ditch.  Consequently, in periods of even light rain, the  sewage con-
tained in the pipes would boil up,  flow through manhole covers, and mix
with the surface water which was running across plaintiff's premises.
The court recognized the common enemy doctrine which allows an upland
owner to divert water from his premises by casting it upon the land of
another.  The city was found to have artificially impounded the surface
water and to have cast it upon the  plaintiff's servient estate in a de-
structive manner, thus violating a  recognized qualification of the doc-
trine.  Accordingly, damages were awarded in favor of the plaintiff.

Plaintiff brought this action against defendant city to enjoin the fur-
ther discharge of storm and surface waters onto plaintiff's property from
a storm sewer system constructed and maintained by defendant.  Before
undertaking the construction of the sewer system, the city consulted plain-
tiff and outlined its plans.   After considering the project, plaintiff
gave its consent.  Over nineteen years  passed before plaintiff expressed
its dissatisfaction with the project.   The city asserted that plaintiff
should be estopped from claiming equitable relief because it had given
its consent before the construction was undertaken.  The court pointed
out that a municipality's  collection and discharge of surface waters
upon private property in greater quantity than would occur from the
natural flow is an active  wrongdoing for which a court of equity can
grant injunctive relief.   However,  while the court will not protect an
active wrongdoer under the doctrine of  equitable estoppel, in the present
case, the city was not guilty of active wrongdoing since it was acting
in reliance upon plaintiff's  express consent.   Therefore, the court held
that plaintiff, having had knowledge of and having assented to the construc-
tion and having enjoyed the benefit of  it for many years, was not entitled
to the relief sought.

Plaintiff's land was located downstream from defendant's storm drain out-
let.  Prior to 1928, drainage water from the outlet traveled over un-
developed farm land and emptied into 2 natural brooks.  By the time the
water reached plaintiff's land, it was in a navigable state.  In 1928,
defendant constructed a surface drainage system causing the drainage
water to flow in greater quantity and force, inundating portions of
plaintiff's land.   The court held that where a city deliberately enters
upon a scheme of drainage and, by artifical means, casts drainage water
on private property which would not otherwise receive such water, it
commits a wrong which equity will restrain.

The state of New York has passed extensive legislation dealing with
the problem of water pollution and the protection of public health,
fish, and wildlife.  Their purpose is to safeguard the waters of the
state from pollution.  All waters of the state are included in the
act.  A water resources commission is set up to classify the waters
and determine the standard of purity that should be maintained in
each body of water.  Water is classified according to its usage, i.e.,
drinking, bathing, fishing, and then assigned a standard of purity
that must be maintained.  Hearings by the commission to determine
said standards are to be public.  Pollution of water beyond the purity
standard is made illegal as to both fresh and salt water.  Permits
must be obtained for the operation of a disposal system.  Civil and
criminal penalties are established for violation of these provisions
and the use of injunctions are expressly authorized.  No person other
than the state acquires any actionable rights by virtue of the provi-
sion and it is in no way designed to create new or enlarge existing
rights of riparian owners.

 Plaintiff sold the westerly portion of her parcel of land to the de-
 fendant.  A storm sewer ran along the rear of both parcels and  water
 in it  naturally flowed in a westerly direction.   The deed did not
 reserve  an easement  for the storm sewer in plaintiff's favor.   To
 stop the flooding of his land due to a blockage  of the sewer to the
 west of  him,  the defendant filled in a manhole located on his property.
                               179

-------
This caused a flooding of plaintiff's cellar.  The court held that
plaintiff was not entitled to a temporary injunction to compel the
defendant to remove the obstruction and that an easement for sewer
drainage over defendant's land would not be implied by law.

 Following  a  severe rain storm, water flowed  from  a nearby  highway
 intersection onto plaintiff's property, damaging  said property
 rather  extensively.  Plaintiff brought suit, alleging that the
 damage  resulted from defendant's negligence  in building  and maintain-
 ing  a highway  sewerage system.  The court granted  defendant's motion
 for  dismissal.  It found that the state was  under  no duty  to provide
 drainage for plaintiff's property.  However, when  a municipal corpora-
 tion puts  a  sewerage plan into operation, it becomes liable for
 damages  resulting from negligence in the construction and/or the
 maintenance  thereof.  In the case at bar, the evidence failed to
 establish  any  such negligence.  The court also held  that a munici-
 pality  is  not  liable for an increase in flow of surface waters  resulting
 solely  from  the paving of streets and the placement  of other improvements.
 Liability  may  exist if the state diverts the surface runoff of  a  water-
 shed from  the  course of its natural flow or  collects such  runoff  in an
 artificial channel and discharges it in great volume upon  the lands of
 another.   But, in this case, the evidence disclosed no accumulation
 of water beyond that which would normally result  from the  construction
 of streets and roadbeds.

The plaintiff brought suit to recover for the flooding of his manufac-
turing plant, allegedly caused by the defendant's negligent sewer con-
struction.  The court found that the sewer outlets were not large enough
to handle the accelerated water flow from a heavy rainfall.  As a
result of this condition, water was cast upon plaintiff's land in sub-
stantial quantities.  The court found that the inadequacy of the drain
to handle the accelerated waterflow was the proximate cause of the
flooding and entered judgment for the plaintiff.

 The  defendant  City of Greensburg installed a 14  inch storm sewer  that
 extended along the westerly edge of  a city street in a southerly  direc-

 48 inch storm sewer which passed in a general southerly direction to
 realestate  owened  by plaintiffs.  Plaintiffs filed a suit  to  recover
 for  damages resulting to their property when defendant diverted
 surface water through the system onto plaintiffs' land. The  jury
 returned a  verdict for  the plaintiffs and the defendants moved for
 a new trial.   On appeal, the court held that the determination of
 defendant's liability was properly left to the jury.

Plaintiffs brought this action seeking damage for injuries to  their
land and building caused by surface water which was diverted onto
their land when defendant filled a low area on his property.   The
depression, xAich filled with water after heavy rains, had been
located mainly on defendant's property, but had also extended  to
plaintiffs' property and to parts of other lots.  Defendant took
no special steps to provide a new drainage receptacle or avenue
for collection or conveyance of surface water.  During subsequent
heavy rains, surface water, drained from defendant's lot, among
others, and from plaintiffs' own lot into plaintiffs' building,
causing considerable damage.  The court found that under the common
law as adopted by Virginia, each landowner may protect his property
from surface water damage as he sees fit, so long as he does not
act wantonly or carelessly at the expense of other landowners.
Plaintiffs failed to show negligence in defendant's filling and
grading.  The court held that defendant need not maintain a catch
basin on his property for plaintiffs' benefit.

Plaintiffs owned buildings fronting on city streets.  The area was within
a natural saucer-like depression.  A storm sewer in the area was laid in
1906.  Improvements after that time mostly by the city, caused the level
of the streets to be raised and soil by which rainfall would normally be
absorbed to be covered.  A relief sewer was later added.  At least one
plaintiff had suffered damages as a result of flooding due to a series
of heavy rains.  In 1949, another heavy rain fell, whereupon, several
buildings in the area became flooded.  Plaintiffs brought actions against
the city, both on negligence and nuisance theories.  The trial court
found that there was no inadequacy or insufficiency in the original sewer
plan, that the rainfall in 1949 was extraordinary, and that the city did
not maintain the sewer system negligently.  The appellate court affirmed,
ruling that the city was under no obligation to collect the rainwater in
the street; but if it actually took possession of such water and thereby
assumed responsibility for it, it may have been liable for subsequently
permitting it to escape on adjoining property.  The plaintiffs failed to
prove what part if any of their damage resulted from the backing up of
the water in the sewer, contrasted with that from the flooding by surface
water.  The court held that attempting to label the condition a nuisance
could not change the respective rights.

The Porter-Cologne Water Quality Control Act, a complete revision of the
State's water quality laws, became effective January 1, 1970.  The Act
accomplishes the following objectives:  (1) grants the State Board ex-
panded powers to provide more leadership and greater influence over ac-
tivities of regional boards;  (2) requires regional boards to adopt more
restrictive water quality control plans and discharge requirements so
that better pollution control will be achieved; and, (3) makes major
changes in enforcement procedures, including court assessment of $6,000
per day fines, which will give boards much more effective means for tak-
ing enforcement actions.  Indications are that over 1,000 environmental
quality control bills will be considered during the current legislative
session.  Consideration will be given to having a State sewage construc-
tion grant program.  Major proposed water pollution control legislation
will be summarized.

 The State Water Resources Control Board and the nine California Regional
 Water Quality Control Boards are the state agencies responsible for con-

 Quality Control Act greatly strengthens and expands powers and duties of
                                185

these agencies.  Although there are many factors contributing to the deg-
radation of water quality, discharges from municipal and industrial waste.
treatment plants are still the principal cause of water quality problems.
Under the new law, requirements will be made further restrictive, result-
ing in highly sophisticated and more complicated treatment plants.  Exact-
ing performance by operators in charge of plants will be needed to prevent
violation of requirements and to collect fines up to $6,000 per day.  To
help assure that qualified operators will be in charge, the State Board
will classify all treatment plants and specify the level of competence
necessary to operate them.  The Board will also specify the training
necessary to qualify an operator for each level of competence.  All oper-
ators should take advantage of training opportunities in order to qualify
themselves for new levels of operating competence.

An urban  river system was employed to establish water quality standards
in the Takamatsu area.  Normally the standard  is established by an in-
vestigation of the individual source of pollutants.  In large cities
where numerous sources exist, an exhaustive investigation is impracti-
cal; consequently, an average water quality standard, based on a sampl-
ing  investigation of primary sources of pollutants, together with con-
siderations of the special properties of the water area are taken as a
basis in  establishing the individual standard.  This new system was
effective in expediting the formulation of the standard.  The general
situation of the water area in question, status of water utilization,,
water pollution, results  of investigations on  water quality, pollutants'
source, planning of the public sewage system,  and future prospects of
water pollution are presented.  Basic factors  considered in establish-
ing  and finalizing the water quality standard  are given.  Discussions
made at committee meetings for establishing the standard are also in-

 Water pollution abatement is  being realized in Great  Britain due to the
 construction  of varying  types of  purification plants  which produce
 effluents  fit  for  discharge to public sewers or rivers.   Past and pre-
                                 187

-------
sent legislation and national policy in the area is described along with
techniques used in water pollution abatement.  Major improvements have
been made possible by granting complete power to municipal authorities
to control industrial discharges, thus, insuring that mixtures of sewage
and industrial effluents are treated in accordance with required stand-
ards.  Pollution control procedures covered include:  industrial water
reuse, metal finishing waste treatment, sewage treatment plants, plastic
filter media, and slude disposal.  In Britain, maximum amounts of storm
water are purified.  Trunk sewers convey 6 d.w.f., but sewage treatment
plants complete purification to only 3 d.w.f.  The remainder spills into
tanks of 6 hour d.w.f. capacity, and it is later pumped back for treat-
ment.

The Porter-Cologne Water Quality Control Act,  effective January 1 this
year, provides  the State Water Resources Control Board and the nine
California Regional  Water Quality Control Boards with the "tools" to
implement and  carry  out an effective water quality control program.  The
new law  is geared  to enhance the water environment as well as to prevent
water pollution.  This  is evidenced by the inclusion of esthetic enjoy-
ment and the preservation of fish,  wildlife and other aquatic preserves
among the water uses to be protected.  Other major provisions of the new
law include:   civil  fines up to $6,000 per day for violation of cease
and desist orders relative to a waste discharge; payment of a filing fee
not exceeding  $1,000 to accompany a report of a proposed or material
change in a waste discharge;  mandatory cleanup of pollution by a viola-
tor with full  liability for cleanup costs; and integration of water
quality  into consideration of water rights, including appropriation of
water by storage to  be  released in order to protect or enhance water
quality.

As the Court  stated in a North Carolina case,  municipalities can be held
liable for damages caused by their failure to maintain proper sewer con-
ditions  including  good drainage and freedom from obstruction.  Thus,
when a locality utilizes a natural waterway for sewerage and drainage,
it is  obligated to keep this water in proper condition, and it is liable
under  the law for  damages resulting from neglect to perform this duty.

-------
The presence of phosphates in surface waters may be caused by municipal,
industrial, and/or agricultural sources.  Millions of pounds of phosphate
enter lakes and streams each year.  An estimated 120,000 to 200,000 Ib
(54,500 to 90,800 kg) of phosphorus (as P) were measured daily in the
Maumee River Basin in Ohio.   Agircultural sources, animal wastes, and
lake bottom muds are important sources of the phosphate nutrients in ad-
dition to wastes encountered at wastewater treatment plants from domes-
tic disposal systems, urban  runoff and drainage, and stormwater overflow.
The removal of P from treatment plants may be accomplished by chemical,
chemical biological,  and other methods.  Phosphates are important ingre-
dients of detergents because they soften water,  sequester,  emulsify,
provide alkalinity and many  other advantages.

In a joint discussion at the annual conference of the AWWA in
May 1966 several speakers discussed various aspects of the problem
of disposing of wastes from vater treatment plants without causing
pollution.  Local factors were taken into account when deciding
whether or not such wastes were likely to have an adverse effect
on the receiving water-  The effects of Pennsylvania state water
quality standards and of federal pollution-control legislation
on the disposal of wastes from water works were considered, and
the methods of disposal at Detroit, Michigan, were described by
G.J. Remus.  One of the Detroit works is situated on the banks of
the Detroit river and the filter wash-water from this plant is
discharged directly to the river; since the flow is rapid, the wash-
water is dispersed rapidl/ and there is no evidence of sludge
deposits.  The wash-water is chlorinated before discharge and is
bacteriologically of better quality than the river water-  The
other three water works are situated away from the river; at the
largest of these the filter back-wash water is recirculated for
reuse, while at the other two it is discharged to a sanitary
sewer, and settled before discharge to a storm sewer, respectively.
The sludges from the sedimentation tanks at all the plants are
discharged to the sanitary sewers.

An account is given of plans for a large biological treatment plant
to be built in Essen, Germany, to deal with the increasing quantities
of sewage to relieve the existing Emscher plant.  The new plant will
be able to treat a load of 20 m^ per second, and during rainfall
this amount can be increased to 30 m  per second.  Provisions have
also been made to construct the influent and effluent channels of the
mechanical stage  in such a way that a loading of up to 1+5 m  per
second would be possible.  The section where the preliminary treatment
is carried out is to be built below ground to that incoming sewage
can enter without pumping; the biological stage will then be built
above ground and the sewage will be pumped into individual tanks
accomodated in 3 buildings.  The plan for separate units applies
to the whole plant for convenience of necessary repairs.  Special
provision is made for the separation of oil.  Oxygen is supplied
mechanically to the aeration tanks, which will have a total volume
of 180,000 m; the final sedimentation tanks will also have a volume
of 180,000 m3.  Primary sludge, amounting to about 60% of the total
sludge, is to be transported to the sludge-drying plant in Essen-
Karnap via a pressure pipeline.  Experiments are at present being
carried out on methods for disposal of excess activated sludge.

 A new sewage  disposal scheme is under construction to eliminate sea-
 shore pollution caused by  direct  discharges to the ocean through
 two  conventional outfalls.  The plan involves pretreatment of sewage
 after which it is pumped through  a long outfall pipe to a point two
 miles offshore.  The  pumping station will handle  sewage flows up to
 6 dwf or 7.5  mgd, and a  combination storm weir and automatic pen-
 stock will pass excesses to the stormwater sump.  A culvert will
 connect the stormwater sump to the foreshore, and for sea-levels
 below mid-tide the  stormwater  will discharge to the sea by gravity.
 At other times when the  culvert is tide-locked, a stormwater pump
 will operate.  Descriptions of physical characteristics, workings,
 and  methods of construction of the long sea outfall and the pumping
 station are included  along with a diagram of the  new sewerage
 scheme.

Prior to installing General Motors'  automatic transmission treatment
plant, plans were made for the separation of industrial wastes from
other liquid wastes.   Separation of sewage and sanitary wastes was
accomplished by laying interceptor sewers from washrooms to connect
to municipal sewers.   Stormwater was separated through the construc-
tion of an overhead collection system connected to rainwater leaders
from the roof.  Clean cooling water from production operations was
also pumped into this overhead collector and the contents fed to
municipal storm systems.   Industrial waste purification was accom-
plished through the installation of the complex waste treatment
plant, which is described in detail and which, since September 1968,
has passed only treated industrial wastes to municipal sewers.

The sewage outfall project at Lowestoft is  controversial in concept
as well as in mode of construction.   Problems of such outfalls include
their frequent damage by heavy seas and their questionable ability
to adequately disperse effluents.  Sea currents at discharge points
were investigated and found to be conducive to properly carrying
effluent out to sea.  The slightest beach pollution, however, will
promote intense public distrust of the plan.  Discharge shafts of the
tunnel beneath the sea-bed will be raised through the use of massive
hydraulic jacks, an unusual technique.  Both the tunnel work and
the shaft raising will be done employing compressed air.  Dimensions
of the tunnel and other construction techniques and problems are
related.  The scheme adopted is inexpensive with regard to capital
and service costs.  A complete sewage treatment works for the town
would cost at least twice as much.

Extensive main drainage and sewage disposal schemes were completed
at Tiverton, Devon.  Plans involved relaying of the town's sewers,
the provision and renovation of pumping stations, and the reconstruction
of sewage disposal works.  All three aspects of the work are fully
described.  Previous town sewers consisted of old brick culverts
which were badly silted, and infiltration water entered in places.
A complicating factor at Tiverton is that the works are susceptible
to flooding from the nearby River Exe.  This complication was
considered in the design of the works, particularly with regard to
sludge treatment.  To overcome problems of drying sludge, a method
of mechanical drying, called sludge pressing, was installed.  A
mixture of primary, humus, and stormwater sludges is passed to a
chemical conditioning tank where lime and ferrous sulphate solutions
are added and mixed with the sludge.  The pressing, which takes about
seven hours, is performed automatically.  The entire procedure is
outlined.

Andover's  new sewage treatment  works  embodies  four unusual  design
features,  namely,  dual  purpose  primary sedimentation  and  stormwater
tanks,  double filtration,  elutriation, and filter pressing.  As a
temporary  extension, three sedimentation tanks were constructed to
deal with  an excess dry weather flow.   The original pumping station
was converted to a stormwater pumping station, and preliminary treat-
ment units were replaced by an  inlet  works composed of coarse  screens,
a bypass channel,  flow  controlling  weirs,  and  a  storm overflow chamber.
Flows up to 3 d.w.f. pass  to the new  main pumping station.   Flows
between 3  and 6 d.w.f.  surcharge and  pass  to the old  station converted
for stormwater pumping.  Flows  exceeding 6 d.w.f. discharge into
existing stormwater tanks.   The rectangular sedimentation and
stormwater tanks were combined  into one unit of  eight tanks, four
back-to-back with a gallery between.   Advantages of  this  system are
cited.  Descriptions are given  of the previous facilities,  effluent

Major items are presented from a longer paper that described in detail
the design, operation, and problems involved in construction of the

by the old Bybrook works, flows exceeding 6 d.w.f. discharged directly
to the old River Stour.  Old stormwater storage tanks, previously
serving Bybrook only, were improved and a short weir constructed so
that all flows pass through both tanks before discharge to the
river.  Two auto sludge scraping mechanisms aid removal of sludge
which is returned along with the tank contents by a stormwater pump
to the works for full treatment.  The following topics relating to
the new disposal works are discussed:  trade wastes, the standard of
effluent, inlet works, settlement tanks and filters, humus tanks,
the irrigation area, stormwater, sludge treatment, commissioning
techniques, percolating filters, the digestion plant, mechanical
plant problems, the pumps' insides and filter arms grounding.   The

The Hastings western area main drainage scheme includes a sewerage
outfall, two new pumping stations, a partial treatment works, and
a pumping main.  The scheme was designed to replace two conventional
outfalls which caused pollution of the foreshore and shallow water
because of insufficient length.  The new outfall was built up into
seven strings in a special assembly area, and these sections were
joined successively before the entire pipe was launched into its
final position on the sea bed.  Further  construction procedures
are explained along with the means used to determine the proper
length of the outfall.  The new pumping station pumps sea sewage
flows up to 6 d.w.f., and a discharge to a stormwater sump.  The
sump connects to the foreshore by a culvert and for sea levels below
mid-tide, stormwater discharges to sea by gravity.  At times when
the culvert is tide-locked, a stormwater pump operates.  Costs,
dimensions, and other details of the entire scheme are included in
the article.

is proving successful.  The policy of recommending separate sewerage
systems wherever circumstances permit has been vindicated by results
of investigations on the characteristics of discharges from the
stormwater sewers, which are  relatively free from organic matter
although they contain inert suspended solids.  Laboratory studies have

Effluent Water Treat, Vol 8, No 10,  pp 513-516, Oct 1968

Descriptors:  *Water treatment, Waste water (pollution), Sewage.
Identifiers:  Developing countries.

There will be an increase in the volume of vastewater and in the
concentration of pollutants due to the increase in the total use of
water for municipal, agricultural, and industrial purposes.   The
problems created by this increase include:  development of water
resources investigating river morphology and irrigation: sewage
waste stressing the reduction of the oxygen consumable in sewage;
trade wastewater caused by a rapid program of industrialization;
equipment and processes wherein design standards used in industrial
countries were also applied to developing countries, citing the
installation of a treatment plant and an inadequate stormwater system;
water and wastewater management; and water-borne disease.  Research
information is needed for combatting the water treatment problems.

and treating trade wastewaters; raising of weirs on storm sewage
overflows to overcome pollution of the River Learn; and experiments
on the treatment of effluent to permit reuse for industrial purposes.
The works now serve a population of 58,000 and treat an average flow
of 4.5 m.g.d., with an efficiency of 93-7 per cent (based on BOD).
In view of continually increasing loads, a scheme is being developed
for a new works, together with a new Avon valley sewer.  Trials
were carried out using spray-irrigation of screnned sewage on grass
plots with underdrains which removed 89 per cent of the BOD and 95
per cent of the suspended solids.

The city of Chippewa Falls, Wisconsin needed to complete a program of
separating stormwater from its sanitary sewage and waste collection
and treatment facilities, or to provide a method of treating the
combined sewage and wastes.  The project selected consisted of certain
combined trunk sewers, certain minor separate storm sewers, a combined
sewage pumping station, and a combined sewage storage pond.  A detailed
description of the project operations and  results  is given.

Waste disposal is explored as a possible factor in groundvater conta-
mination.  State-reviewed disposal operations in Illinois that are speci-
fically discussed include:  landfills and dumps,  radioactive waste
burial grounds, sewage treatment and waste storage ponds, disposal wells,
and sewage-stormwater tunnels.  The Chicago Sanitary District's tunnel
plan for the prevention of stormwater and raw sewage bypassing treat-
ment plants and polluting streams is described.  Initial reports con-
cluded that stormwater and sewage would not pollute the groundwater
reservoir because the rock in which the tunnel was bored is tight, and
head relations provide that water only moves into and not out of the
tunnel.  Possible problems created by this project are mentioned.
The following suggestions are proposed to aid groundwater practitioners
in waste management;  (l) the selection of sites  for waste disposal
based on hydrogeologic conditions which indicate  natural safeguards
and the protection of health and resources; (2) procurement of data
needed to develop criteria for determining geologic conditions and
beneficial engineering practices; and (3) the study of investigations
relating to waste management topics such as saturation and water move-
ment in typical geologic terrains that might be used for waste disposal.

major existing severs were to be connected to newer sewers, and at
least 6 d.w.f. will be passed to the new sewer-  Primary tanks of
the existing sewage-treatment works will be converted to storm water tanks
and pumps installed to convey stored sewage back to the new sewer.  Ho
flows below 18 d.w.f. should reach rivers without treatment.  Surface
water storm sewers will be built according to the size necessary to
drain the "once a year storm,I! even though rain of this intensity
and duration is not likely to occur more than once in three or five
years.  Descriptions are given of the size, capacity, and mode of
treatment and operation for the numerous parts of the sewage treatment
plants proposed.  No storm water settling tank is envisaged for the
first development, and future expansion and increase in population
will determine whether a storm settling tank is required.  Partial
treatment of 6 x d.w.f. or more will be possible.  Capital and operating
costs for both treatment plants are tabled as are data concerning
capacities  and dimensions of each treatment mechanism.

The author outlines a system  of water pollution control in which all
wastewaters from the area are treated for reuse as municipal or
industrial water supplies.   Wo wastewaters are discharged to public
watercourses, and water is  drawn from natural sources only to replenish
losses by evaporation and other processes.  The choice between combined
and separate sewerage systems in such an area and the selection of
a treatment system for the  wastewaters are considered, and a practical
system of treatment is described comprising removal of grit and sand.
Simultaneous removal of carbonaceous and nitrogenous compounds and
reduction of phosphate by activated sludge with incineration of
excess sludge to ensure removal of phosphate from the system is examined;
as well as chemical precipitation  to reduce carbonate hardness. COD,
phosphates, silica, boron,  fluorides, and viruses, followed by filtration
through diatomaceous earth.  The removal of dissolved solids in a
series of five units consisting of hydrogen cation-exchange column,
three activated-carbon columns, and an anion-exchange column is ex-
plored.  The system recovers about 95 per cent of the initial water.
Water can be removed from the system at several stages for
selected purposes.

An intensive redistribution within and to the Greater-Stockholm area
is expected by the year 2000, and consequently large and difficult
sewerage problems are created.  The problems caused by sewerage and
sewage discharge in the surrounding area of Stockholm are discussed
in relation to treatment facilities now in use.  Two courses of
problem solving are described as:  l) tunnel systems for sewage
collecting from catchment areas which would carry the sewage for
the whole region to a common sewage treatment plant with ocean
discharge; and, 2) a tunnel system constructed as an outlet conduit
to better receiving waters for the biologically treated sewage from
various existing sewage treatment plants.  No decision has been made
as to which method will be employed

An investigation,  which deals vith the assessment of alternate
methods for control/treatment of combined sewer overflows for the
District of Columbia, is presented herein and has the following
three components:   l) problem definition, 2) the study of the feasi-
bility of high-rate filtration for treatment of combined sewer flows,
and 3) the study of alternative methods of solution.  Problem defi-
nition dealt with attempting to define hydraulic properties and water
quality characteristics of combined and separated storm sewer flows.
The second major area of study, high-rate filtration, was investigated
by bench-scale laboratory experiments.  The third part of the investi-
gation was accomplished by analyzing various approaches used in other
parts of the country relative to their applicability to the Washington,
D.C. system.  This paper presents a discussion of the three major
portions of the investigation.  The approaches are described and
appropriate conclusions presented.

Emphasis has recently been placed on up-grading effluent standards to
maintain, or improve, river qualify in lieu of increasing contamination
from municipal and industrial discharges.  Each state mazt formulate
standards for waste water treatment as a resUlt of legislation intro-
duced by the Federal Government.  Increased attention has been paid
to the compounds of phosphorus and nitrogen in effluents since these
chemicals provide nutrients for plant life in the receiving stream.
The basic operating principles of a typical microstraining installa-
tion are reviewed.  The article outlines the results from three in-
vestigations in which microstraining has been assessed as an economic
aid in preventing pollution in: l) Lebanon, Ohio -where methods of
removing suspended matter that tend to overload advanced waste treat-
ment processes were explored: 2) Chicago - where the necessary tertiary
treatment stage at three plants is being determined in order to meet

The Atherston Rural District Council constructed a new sewage treat-
ment works and installed several miles of trunk sewers to supercede
three existing, overloaded works and to provide for mains drainage
in two towns not previously sewered.  An activated sludge plant was
also proposed for construction.  The partially separate sewers in
most of the villages were adequate for even anticipated future flows,
but in a few instances where surcharging occurred, new sewers were
laid.  In one area, storm overflows on the sewers were considered to
reduce flow to the new works, but separation at the site of the works
was found to be preferable.  A complete description of the design of
the new works is given.  Storm tanks can hold the equivalent of
12 hours d.w.f.  At times of very heavy rainfall, tanks overflow
to Penmire Brook.  After a storm, contents of the tanks are returned
to the pumping station to be lifted to the works for treatment.  The
treatment process and sludge handling are described.

Spilsby RDC's sewerage scheme involves two sewage treatment works and
construction of a 1.5 mile outfall sewer to dispose of effluent from
both works.  In one works, storm flows exceeding 3 d.w.f. are separated
and passed to storm tanks and additional flows screened only before
passing to the final effluent sump.  The previous raw sewage, storm-
water, and effluent pumping plant was augmented and the filter
distributer arms replaced with others of greater capacity.  The outlet
sewer system was revised to take the effluent to the submarine outfall.
Modifications of the second works provided a degree of treatment
similar to that at the first works.  The bitumen enamel-coated steel
submarine pipeline is described in addition to methods used for trench
excavation and launching.

Tabulated and graphical results are given of laboratory studies on

sedimentation for less than one hour was not effective in reducing
COD, BOD, concentrations of nitrogen, phosphate and solids, or the
total counts of three bacterial indicators, but improved removals
were obtained with sedimentation for four hours.   A dose of 2-6 mg
of chlorine per litre applied for 20 min was neccessary to effect a
99-99 per cent kill of total coliform organisms,  faecal coliform
organisms, and faecal streptococci.  Even with such high doses of

chlorine and the presence of free residual chlorine after treatment,
aftergrowth of total coliform organisms occurred in 2k-12 hours;
however, there was no significant aftergrowth of faecal organisms.
From these results it is suggested that the count of faecal coliform
organisms rather than total coliform organisms is more realistic
indicator of the downstream effects of chlorinated discharges.

Identifiers:  *Storm tank, ^Treatment processes, Storm sewage.

New techniques and developments in three different areas are discussed,
the areas being:  sewage treatment and its effect on operators and
others, the effectiveness of sewage treatment, and the efficiency of
the process.  Developments in sludge dewatering and aerial nuisance
decrease the unattractiveness of sewage treatment to operators and
other employees.  The advances and deficiencies of tertiary treatment,
biological treatment, and preliminary treatment and sedimentation are
presented in relation to the influences they have on the effectiveness
of sewage treatment.  Also-in-this area, the failings of storm sewage
treatment are enumerated, and the author strongly recommends that
provisions for storm tanks or irrigation areas be made in order to
reduce pollution from overflows.   He asserts that it is better to inter-
cept a HO d.w.f. flow in a storm tank than to given full treatment to
a mere 6 d.w.f., allowing the remainder to overflow.  F.W. Allen in
the "Discussion," suggests that storm tank treatment could be improved
if full use were made of the storage capacity of sewers and if one storm
has no outlet to the river so that the first storm flush could be
stored there and later sent back for treatment.  He also recommends that
overflows sited on a sewer near a trade effluent discharge be upstream
of the discharge to allow the trade effluent to pass to the sewage
works.  New techniques in the efficiency area of sewage treatment are
also described in addition to civil engineering developments that speed
construction.

Microstraining, using a nominal 23 micron aperture  Microstrainer screen,
has removed up to 98% of the suspended  solids from  the combined sewer
overflow which serves a residential area of 11 acres in the. city of
Philadelphia.  BOD removals and coliform bacteria concentrations in the
microstrained effluents have varied widely.  Results to date indicate-
that there is  a slightly better colon  group bacterial kill with chlorine
in the microstrainer effluents then when ozone is used.  Preliminary est-
imates have been made for the costs of  treatment  for a combined sewer via
the microstraining process.  It is estimated that the costs per acre of
of drainage for a full scale plant in our test area would range from
approximately $9,500 to $11,800 for microstraining  alone, $10,500 to
$12,800 for microstraining plus chlorination, and $18,000 to $21,300 for
microstraining plus ozonation.

 Due  to the high  flows experienced in combined sewer  systems,  treatment
 can  seldom be provided  for the  entire  volume of  combined sewage.   This
 leads to the  problem  of determining the  optimum-partial  treatment  needed
 to meet water quality objectives.   Non-linear programming is  used  to
                                 215

-------
determine the optimum combination of primary and secondary treatment  to
be provided for combined sewer effluent.  Water quality requirements
limiting floating solids, grit, settleable solids, suspended solids,  and
BOD are considered as constraints against an objective function composed
of the cost of preliminary, primary and secondary treatment.  The
nature of the problem allows a graphical solution.  The sensitivity of the
solution to a number of input variables is performed.  The response
of cost to the levels of water quality specified by water quality
regulations is also investigated.  The graphical solution of the non-
linear program gives insight into the nature of objective and constraint
functions encountered in water pollution control work.  In spite of
the very non-linear nature of the constraint functions in a mathemati-
cal sense, the plots of such functions proved to be largely linear.

conditions of the area, a central pumping station had to be provided
to pump the sewage via a long pressure pipe 65 m above water level
to the lake.  The author outlines the factors which affect the use of
combined sewerage systems as compared with separate systems and dis-

Laboratory tests were performed on Type 1 poliovirus and Type 2
bacteriophage with varying chlorine dosages to determine the chlorine
residuals necessary to insure high-level virus inactivation in settled
raw wastewater and stormwater overflow.  Conclusions drawn from the
study showed that high-level inactivation of viruses is possible in
treated and untreated domestic wastewaters, but that present chlorin-
ation practices do not accomplish this feat.  In the experimental runs
with synthesized stormwater overflow, a 100-percent inactivation of
Type 1 poliovirus was achieved by providing a free chlorine residual.
In all runs, the T2 bacteriophage was much less sensitive to combined
chlorine residuals than was the coliform organism and was more sen-
sitive than the poliovirus to combined chlorine residuals.

The feasibility, effectiveness, and economics of employing high-mesh
screening for primary treatment of stormwater overflow from  combined
sewer systems is detailed herein.  Based on final performance  tests
run on dry-weather sewage, the unit (63 inches high and an outside
diameter of 80 inches) is capable of 99% removal of floatable  and settle-
able solids, 34% removal of total suspended solids, and 27%  removal of
COD.  The screened effluent is typically 92% of the influent flow.  The
estimated cost of treatment is 22 cents/1000 gallons for a scale-up
design of a 25 mgd screening facility.  It was observed that the proposed
screening facility required 1/10 to 1/20 the land required by  a con-
ventional primary treatment plant.

Identifiers:  *Combined sewers, *Screening/flotation system.

This report documents a study on the treatment of combined sewer over-
flow by screening and dissolved-air flotation.  The objectives of the
project determined the effectiveness and cost of a screening/flotation
system.  A combined sewer in Milwaukee, Wisconsin was monitored and
testing was performed.  The results of the laboratory tests indicated
a combination of screening/flotation provided a feasible system and
a prototype demonstration unit with a 5 mgd capacity was designed and
installed.  The system has been operated on 30 overflows.  Removal of
BOD, COD, SS, and VSS have ranged between 50 and 75 per cent.  Cost
estimates indicate a total installed cost of $12,000 per mgd capacity.
Operating costs are estimated at l.Oc/1000 gallons without chemical
flocculant addition.

When grants for wastewater treatment plants are made under the U.S.
Federal Water Pollution Control Act, efficient operation and mainte-
nance of these plants must be provided.  To ensure compliance with this
requirement, an appropriate audit is made at each plant after it has
operated for about one year.  In this report, the data from 1500 audits
in the period July 1962 to December 1964 are summarized and analysed
statistically showing mathematical relations between several of the
variables examined.  These relations include:  population, quantity
and strength of wastewaters, operating costs, and type of treatment.
Problems encountered are also summarized, with particular reference
to the bypassing of untreated wastewater as a result of storm sewage
flow or infiltration into the sewers.

Identifiers:  *Treatment methods.

Water pollution abatement activities were given authority and direction
by the Federal Water Quality Act of 1965.  An estimated cost of $48
billion  is necessary for the separation of combined sanitary and storm
sewers.  The traditional primary-secondary treatment plants' objectives
and achievements usually have been not to restore but to slow down or
prevent  further degradation.  Lack of knowledge of the extent and means
of treating pollution sources such as pesticides, acid, erosion, ferti-
lizers,  and mine drainage, is a factor in delaying the abatement program.
A list of consulting engineering firms, which have been awarded research
and development grants and contracts for advanced wastewater treatment
techniques, is given.  The trend in the reuse rather than discharge of
wastewater is well under way, and the most widespread reuse today is
that of  secondary treatment effluent as a water source for industry
and agriculture.  A need for professional water pollution control
is emphasized.

tensions are now being planned.   These will include aeration with
Simplex cones for secondary treatment by the activated-sludge process,
together with new screens, stormwater tanks, and sedimentation tanks.
Automatic control systems will also be installed.  To improve the
performance of the sludge digestion unit, which consists of two con-
centric tanks, it is planned to  install a gas recirculation system to
give better mixing.  Disposal of liquid digested sludge on farmland,
which was begun in 1963 will be  expanded.

action in straight, circular, and mixed oxidation channels are outlined
including the difference in the biological conditions of each plant.
The importance of dilution for the biocenose in circular channels is
considered as well as the factors which affect nitrification and de-
nitrification in straight and in circular channels.

Descriptors:   *Flood routing, *Rainfall, *Frequency analysis,
*Discharge (water), *Hydrograph analysis, *Unit hydrograph, Storm runoff
Rainfall-runoff relationships.
The author deals with two problems in flood hydrology:   (1) predic-
ting peak discharges from rainfall data and such other factors as
are found necessary; and (2) the determination of the frequency of
exceedence of a discharge when records of discharge over several years
exist or in the absence of such records.  The chapter attempts to
designate the tools available for solving such problems and the use-
fullness and limitations of these tools.  Topics discussed under
hydrograph analysis are:  storm runoff from individual storms, rainfall
and effective rainfall, the unit hydrograph hypothesis, changing the
duration of a unit hydrograph, use of the S curve, calculation of
unit hydrographs from rainfall and stream flow records, and uses of
a unit hydrograph.  The relation between the unit hydrograph and the
catchment is explained, as is the volumetric relation between rainfall
and runoff.  The last two sections explore flood frequency and the
relation of flood frequency to catchment characteristics.  (See ab-
stract number 316).

 The formation of water and  sewer districts  in  a  highly urbanized  area
 composed of fourteen cities is described.   The economical  and  functional
 advantages of such districts are enumerated.   Separate rather  than  com-
 bined sewers are recommended, but the problem  of surcharging sanitary
 sewers during heavy rainfall still  remains.  This problem  is now  being
 combatted through the installation  of additional sewers and holding
 stations which function as  primary  treatment plants when sanitary sewers
                                221

-------
are surcharged.  Skimmings and settled material are continually re-
moved and discharged back to normal sewers, and all incoming waste-
water is chlorinated.  Effluent is conveyed to the receiving stream
after treatment.  This system appears to be successful in that incoming
sewage is highly diluted with stormwater and receiving streams carry
normal flows during discharge periods.  The physical growth of water
resources properties is tabled and long range plants for the area are
discussed.

The sewerage system of the Los Angeles County Sanitation Districts
serves about 4 million people in 71 incorporated cities and large
tracts of unincorporated areas.  Because of the serious problems
caused by water shortage in these heavily populated  areas, the sani-
tation districts have instituted the latest techniques and facilities
in water reclamation.  The Whittier Narrows Plant, the Pomona research
and demonstration program and the Lancaster project  provide sound data
for future planning of similar facilities.  The initial stages of the
40-yr master plan that will provide approximately 440 mgd of potentially
reusable water in the districts' system are underway.  The sanitation
districts in Los Angeles County are pursuing research and pilot scale
operations of various tertiary treatment processes to provide reclaimed
water of any desired quality.  Descriptions are given of the processes
being used.

The adoption of metropolitan programs for water supply, pollution
control, and sewage treatment in the Detroit area received its impetus
in 1959.  A brief review of the growing acceptance of the programs is
given.  The sewage system for Detroit operates on a combined stormwater-
sanitary sewage basis with the use of remote controls, automatic alarms,
and computer recordings (including records on how a storm crosses a
metropolitan area).  The stormflow dirt deposit to the Detroit River
has been reduced by at least 15%: and because of the sewer control
instruments flooding of the activated sludge process at the plant.
Approximately $371 million will be spent from 1966 to 1975 on this
water pollution control program.  Recommendations for further studies
and programs are made by the author, and an estimated cost list on
the sewage disposal construction (1968-1970) is given.

The author contends that there is no single method of either control
or treatment applicable as a complete answer to combined sewer problems,
He further holds that engineering studies must consider all potential
alternatives when seeking to determine a treatment method, and that
physical control by storage must be considered in conjunction with
potentially applicable treatment methods in order to achieve an op-
timal system.

Three basic approaches used to minimize combined sewage or stormwater
pollution are defined as:  (1) control, (2) treatment, and (3) com-
binations of the two.  Examples are given under each category.  Con-
sidering progress thus far, it is unlikely that any single control or
treatment method developed will successfully solve combined sewer or
stormwater pollution problems.  Instead, methods providing whole or
partial solutions based on particular circumstances of the area will
be integrated into the combined sewer or stormwater project.  Methods
of control and/or treatment described include:  screening, disinfec-
tion, sedimentation, in-system storage, off-system storage, chemical
treatment, automated regulators, and sewer separation.  Sewer sepa-
ration continues to maintain the widest amount of present and planned
use and predicted applicability.

gallons^of purified waste water into a new reservoir for water sports
and irrigation; and, the Windhoek (South West Africa) sewage puri-
fication plant, using a different system, will have supplied nearly
one-third of the drinking water for a city of 30,000 people for more
than a year.  The paper presents illustrations, flowsheets, and cost

In June 1969, the Dow Chemical Company started to take into its cooling
water and fire protection system the treated sewage from the city of
Midland, Michigan.  The supplemental water supply will provide up to
seven million gallons per day of relatively high quality water and the
reservoir will provide a three million gallon fire water supply.  The
Midland waste water treatment system consists of primary, and two stage
trickling filter secondary treatment, followed by chlorination.  There
is also a. three million gallon reservoir, two six thousand gallon per
minute pumps, and associated controls and piping.  The total cost of
the project is estimated at $500,000.

ment concept set forth in the research creates new information needs.
The concept is one of utilizing pollutants as resources out of place and,
thus, converting them into economic goods.  This goal is accomplished
by taking the waste from the water, processing it, and putting it on the
land, where it becomes useful and valuable.  The environmental im-
plications and the data needs for such a program can be viewed readily
in the context of this new type of urban water resource management.  It
is obvious that adjustments in mapping techniques will be necessary
to accommodate future management efforts.

 Modifications  are examined in relation  to preliminary aeration equip-

 passing through a grit  chamber and storm-sewage overflow,  is  conveyed
 directly to a holding tank,  inside of which  is a container whose upper
 rim is at the same height as  that  of  the plant itself.   A compressed-
 air lift,  mounted in the holding  tank above  the bottom of the tank,
 comprises  a vertical shaft with aeration jets.   This  compressed-air
 lift has a two-fold effect:   it lifts the"sewage into the treatment
 tank,  and it  provides primary aeration.

This article discusses extensions to the Oxford sewage purification
works.  The design approach to two widely differing water retaining
structures, the primary settlement and storm/balancing tanks and the
elevated wash water tank to the sand filtration unit, are considered
in some detail.  The common thread was the elimination, where possible,
of complex stresses either by introducing hinges or movement joints.
Shrinkage cracking is more difficult to avoid.  Possible methods of
reducing such cracking are discussed.  The importance of efficient and
continuous curing from the moment the shuttering is struck, or in the
case of slabs, from the time of initial set is emphasized.

 of 90,000 with a dry-weather  flow of 320 litres per sec, and a  storm-
 to 1200 mg per litre.  To reduce the heavy load, the plan includes:
 additional pumping stations at Galwick; the extension of the pressure
 pipeline to a length of 1450  m; and a treatment plant equipped  for
 the activated-sludge process, with sludge digestion followed by
 thickening and drying on beds,  and disposal at sea by ships.

Hydrologic principles of the calculation of runoff from rural areas
are also applicable to urban and combined rural and urban catchments.
However, traditionally urban runoff has been calculated by a varia-
tion of the basic method called the Rational Formula or the Lloyd-
Davies formula.  This formula has been shown to be reliable only for
very small urban catchments, and it is being replaced by the R.R.L.
Hydrograph method.  This chapter discusses the R.R.L. Hyd.rograph
method based on climatic conditions in. Great Britain.  In order for
this method to be applied elsewhere, suitable rainfall data must be
employed and adequate allowance made for increased impermeability of
natural surfaces, particularly under conditions of tropical rainfall.

Expansion of a Royal Thai Air Force Base necessitated development of a
flood control system to alleviate drainage problems.  An area-wide
drainage study considered four possible solutions:  (1) a concrete-lined
trapezoidal channel to carry runoff around the new runway overrun; (2)
a collection basin and pump near the runway; (3) a multicell box culvert
under the runway extension; and (4) a flood control storage reservoir
with controlled discharge.  The economics and feasibility of the four
plans were discussed based on a two-year design storm condition, and the
storage reservoir method was decided upon.  Interior base drainage con-
sisted of a system of ditches, collection channels, and storage basins,
plus three pump stations.  The new flood control system will also some-
what relieve flooding of the neighboring city by decreasing the runoff
rate to it.

In the field of surface water hydrology, the fundamental equations of
motion and continuity adequately portray the overland and channel flow
phenomena.  The differential equations, however, are not easily amenable
to solution, and their integration in closed form can be obtained only
for extremely simplified cases.  Techniques of integration by numerical
methods have been developed, which can be handled by use of electronic
computers.  Combined with basic mathematical operations, the electronic
analog computer can be successfully employed in the solution of surface
runoff models described in terms of the 2 fundamental equations.  The
watershed is divided into subzones based on topography or physiography.
The subzone is simulated by an equivalent rectangular basin transected
by the main stream channel.  Using the 2 fundamental equations of flow,
the water is routed over the basin slopes with the rainfall as input and
through the channel system which receives lateral flow from the basin
slopes.  Models based on the derived equations and on simplified forms

of these equations are being developed in an attempt to assess the va-
lidity of these equations for some simplifying assumptions made in the
usual routing procedures.  Tests of the mathematical models are being
made by simulating subbasins of the Walnut Gulch Experimental Watershed

Several topics were investigated under the general heading 'Generalized
Analysis of Small Watershed Responses.'  Each topic resulted in a self-
contained report:  (1) The functional series representation for nonlinear
physical system was used to develop a method permitting the determination
of a nonlinear prediction equation and the nonlinear response functions
for hydrologic systems.  The method was tested successfully using rain-
fall and stream flow data of a small California watershed.  (2) A method
of curve fitting was applied to precipitation data of an array of rain
gages in a small California watershed to obtain a functional representa-
tion of the time and space distribution of storm rainfall.  This method
may be used for the establishment of criteria for precipitation network
design and for the analysis of watersheds and nonlinear systems with
distributed input fields.  (3) A simply cascade model of the rainfall-
runoff process was developed to test whether the design of more complex
mathematical models is justified from the standpoint of runoff prediction.
(4) A detailed mathematical model of the physical processes producing
snowmelt was developed.  It is suitable for the prediction of net water-
shed inputs due to the fusion of snowfields, and may be incorporated
into a comprehensive watershed model.  (5) A study of the accuracy of
the prediction of floods of high return period was conducted.   It pro-
vided expressions for the standard errors of sample estimates of flood
magnitudes corresponding to given return periods for normal and double
exponential universes.  Jointly these topics contribute to a better
understanding of various statistical and physical aspects of small water-
shed behavior.

The general  theory  of nonlinear  synthesis and  analysis  in hydrology is
discussed, with  particular  reference  to  the problems of predictive un-
certainty.   These problems  are associated with incomplete descriptions
of the hydrologic systems,  limited model-prototype equivalences, system
variability  in time, and  system  nonlinearity.   Solutions to the nonlinear
analysis  problem of hydrologic systems under the assumption of approxi-
mate  time invariance, based on complex cascade network  approximations,
power series and polynomial expansions,  and variable response function
approximations are  presented.  The relations between present theoretical
knowledge and its practical application  are summarized.

 R. K. Linsley and N. H.  Crawford:  The authors uphold and dispute some
 of the  conclusions of AmorochoTs paper.  They dispute the application of
 Heisenberg's uncertainty principle to hydrology.  Also, they question
 Amorocho's suggestion for an evaluation of the probability distribution
 of the  difference between outputs computed by a model and outputs mea-
 sured in the prototype system.  The  authors support the opinion regarding
 the futility of pursuing strict determinism in hydrologic research.  J.
 Amorocho:  In response to the above  objections to the application of the
 Heisenberg principle to  hydrology, he supports his statements with ex-
 amples.  He also defends his other conclusions, and he agrees with the
 discussers' opinion regarding the advantages of some knowledge of the
 structure of hydrologic  processes.

The paper presents a critical review of current methods employed for the
establishment of quantitative relationships between precipitation and
runoff in hydrology.  These procedures, which are classified under the
general categories of "parametric" and "stochastic" hydrologies, include
the methods of correlation analysis, partial and general synthesis,
general nonlinear analysis, and statistical simulation.  They are studied
as mathematical models of the hydrologic systems, having specific theo-
retical properties and limitations.   The structures of these models are
examined with the aid of flow charts, and the areas of their optimum
application are suggested.

Identifiers:  Urban hydrology, Urban floods, Flood peaks.

Graphical and mathematical relations are presented to estimate the flood
peak  magnitudes having recurrence intervals ranging up to 100 yr for
drainage basins with various degrees of urban or suburban development.
Five  independent variables are required for use of the relations.  They
are basin size, length, and slope which may be measured from maps, and
percentage of impervious surface and type of drainage system which may
be evaluated by a basin inspection, but which in actual practice will
usually be estimated for future developed conditions.  The estimating
relations are based upon analysis of flood information for 81 sites, 59
of which are in the Washington, D. C. metropolitan area.   The relations
are judged to be of adequate accuracy for design of drainage systems and
for definition of flood limits.  Urban and suburban development are shown
to significantly affect flood flows.  Improvements to the drainage system
may reduce the lag time to one-eighth that of the natural channels.  This
lag time reduction, combined with an increased storm runoff resulting
from  impervious surfaces, increases the flood peaks by a factor that
ranges from  2 to nearly 8.  The flood peak increase depends upon the
drainage basin characteristics and  the flood-recurrence interval.

Streamflow from two 30-acre watersheds near Honolulu was studied by
using principal components regression analysis.  Models using data on
monthly, storm, and peak discharges were tested against several variables
expressing amount and intensity of rainfall, and against variables ex-
pressing antecedent rainfall.  Explained variation ranged from 78 to 94
percent.  The analysis provided some clues as to the dominant hydrologic
processes under three different watershed conditions.  The lack of
change in the coefficients relating precipitation to runoff in the pre-
and post-fire periods may be interpreted as indicating that the burning
of the watershed had little effect on the infiltration of percolating
capacity—at least not in the range such as to affect rainfall excess or
storm interflow or both.  On the other hand, the increase in the regres-
sion constant indicates that the burning of the watershed had its ex-
pected effect in reducing any storage that was readily available for
evaporation, such as the interception storage.

also samples and records the rate of runoff in such a way that sediment
production can be measured accurately.  The major components are:   (1) a
1500 gallon tank truck for transporting water and apparatus, (2)  a  de-
mountable aluminum framework and moving spray assembly for applying water,
and  (3) a device for sampling and measuring the rate of runoff.   Two  men
can  assemble it and put it in operation in one and a half hours.  The

 lag.

Lag  time for a catchment is shown to be a variable which is strongly
 correlated with flood magnitude, and the use of direct rather than  sur-
face runoff increased the degree of this correlation and offered  other
 potential advantages.  Values for various parameters  of  rainfall  and
 runoff were derived  from the  analysis  of  records for  five small  catch-
 ment areas.  Lag  time is defined as  the time between  the centers  of mass
 of excess rainfall and direct runoff.  Weighted mean  discharge  is used
 as the measure of average streamflow magnitude.  No significant  correla-
 tion is found between the lag and various characteristics of the  areal
 and  temporal distribution of  rainfall.  Therefore, the lag-weighted mean
 discharge equations best represent the variable lag time for the  catch-
 ments  studied.

An investigation was made of the values of lag time for natural catchment
areas, as measured from center of mass of excess-rainfall to center of
mass of resulting runoff.  Any variation in this value for an individual
catchment is an indication of a nonlinear response.  Values of lag were
measured for a range of floods on 5 catchment areas.  The difference in
value between catchments was found to be a function of the catchments'
characteristics, while variation in the values for an individual catch-
ment was strongly related to the magnitude of the floods.  As the degree
of this variation was fairly constant for the areas studied, the degree
of nonlinearity was also considered to differ little between the catch-
ments.  The development of 3 general formulae required a detailed anal-
ysis to be made of a large volume of hydrologic data by an objective
systematic procedure.  For this purpose lag was measured to the center
of mass of direct runoff and a weighted mean discharge measure of flood
magnitude was devised.  Numerous hyetograph characteristics were measured
and studied, but none appeared to have any significant influence on the
value of lag time.  Computer program listings for computing lag-discharge
relationships and for regression analysis of lag-discharge relationships
are included.

Distinct differences exist between estimating specific floods from data
on specific rainfall events and estimating design or representative
floods from rainfall statistics.   The latter should be regarded as a
more generalized procedure in which high accuracy cannot be expected.
Many physical details of specific events are irrelevant for estimating
representative events.   A single  parameter is sufficient to express the
time-distributing characteristics of a watershed for design purposes.
The suggested parameter is the representative lag, closely related to
the volume/peak ratio.   For small watersheds in the western U.  S., the
same return period may  be assigned to the design flood and the corre-
sponding extreme rainfall.  This  finding is not expected to apply to all
climatic situations, but may be a reasonable assumption in the absence
of any other information.  The rational-loss rate method is suggested for
estimating extreme floods from extreme rainfall because of its simplicity,
flexibility, and consistency with the requirements and limitations of
the problem.  This method does not give satisfactory reproductions of
the 10-yr floods on the test watersheds and cannot be strongly supported
by this performance.

By using analytical methods, successive restrictions were imposed on a
mathematical version of the U. S. Weather Bureau's graphical surface-
runoff model to develop an analytical model that expresses the API
(Antecedent precipitation index)-runoff relations with 2 equations and
                                  242

5 coefficients.   The analytical model is similar in concept to the
graphical model  in that both relate rainfall, week number, and the API
measure to surface runoff.   The concise relations of the analytical
model,  however,  can be rapidly derived from a historical storm list by
computer.  When  tested, runoff relations, derived with the analytical
model over selected watersheds, predicted surface runoff from those
watersheds somewhat better  than the regional, graphical relations devel-
oped for the Tennessee Valley.

A technique has been programmed to solve analytically for measures of
precipitation excess and unit graph shape parameters.  The optimization
procedures achieved a very high degree of adjustment of the model to
data, but the results were inconsistent.  The development of an'objective
fitting  technique is described.  A two-step  fitting procedure was devised
which substantially increased  the objectivity of  the fitting technique.
The  two  shape parameters were  first individually  corrected by a  univariate
technique to near-optimum values.  This  reduced the effect of the higher-
order partial derivatives with respect  to the shape parameters.  The  si-
multaneous  differential correction technique was  then used to obtain
corrections for both the shape parameters and the runoff  parameters.
While this  two-step solution  technique  does  not yield exact results,  they
are  close enough  to the desired values  and can be obtained consistently
from different starting points.

tude must be considered in computing the infiltration capacity.  Hydro-
logically significant impermeable area is probably smaller than the ac-
tual impermeable area, and there is evidence that it is related to popu-
lation density.   For basins near Detroit the significant value varies
from 1% to 10%,  for population densities varying from about 500 to 7,000
per square mile.  Many routing techniques may provide the basis for a
mathematical model of the hydraulics of storm runoff.  One method of
evaluating the influence of urbanization on the runoff hydrograph is to
study relationships between unit hydrograph shape parameters and some
measures of drainage basin characteristics.  Much work has been and is
being done to help find better ways of predicting peak flows from rain-
fall, and more emphasis is being placed on the determination of the ef-
fect of urbanization.

A method for estimating storm runoff from rainfall records is presented
for southeastern Louisiana and southwestern Mississippi.  A rainfall-
runoff relationship generally useful in the study area relates storm run-
off to storm rainfall and the week of its occurrence.  Values of weekly
coefficients and exponents are tabulated.  The standard error of estimate
of this relationship for all storm is about 40%; for storm rainfalls
greater than 4 inches, the standard error decreases to about 25%.  With
these limitations, the rainfall-runoff relations can also be used to
distribute incremental rainfall excess with time.  Records for 20 stream-
gaging stations and 34 rainfall stations in the area studied were used to
compute antecedent rainfall parameters, rainfall duration, total storm
rainfall, and total runoff for 959 storm hydrographs.  Graphical analysis
indicates that regressions of rainfall versus runoff for each week of the
year are as good as or better than regressions involving parameters of
antecedent conditions and rainfall duration for estimating storm runoff.
Apparently, the week-of-year factor accounts for seasonal variations in
duration and antecedent conditions, and use of the seasonal factor alone
will provide useful estimates of storm runoff in the area studied.

 The  extension of  techniques  developed for  the  identification of  response
 characteristics from past  rainfall-runoff  records  to  the  most  general
 case within  the framework  of a  single input-single  output linear system
 theory—time variant system with nonzero initial conditions is discussed.
 The  identification process  is formulated as  the  optimization problem for
 minimization of the  mean square error between  predicted and observed out-
 puts.   It is shown that  the  representation of  a  kernel in linear parametric
 form reduces the  optimization problem to a solution of a  set of  optimiza-

 This  investigation employed  a network of rain-gages to ascertain the
 average areal precipitation  on major zones of the Tyne catchment in
 Northern England.  The  actual rainfall for each storm was compared to
 the predicted rainfall which was obtained by using past rainfall figures
 and surface-wind speed  and direction for each storm.  Errors between ac-
 tual  and predicted rainfall  are tabulated, the mean percentage of error
 being 4.6%.   In  spite of the sparsity of rain-gage  equipment and the
 small number  of  storms studied, this  investigation  demonstrated the
 direct relationship between  spatial rainfall distribution and surface
 wind and topography.   Using  such  parameters, estimations  can be made of
 the  average areal storm rainfall  over subcatchments.  This process could
 be extended to predict flood hydrographs at particular parts of a drain-
 age  system.

The rational formula, Q = c i A, may be considered a rough expression of
the influence of urbanization on stormwater sewer flows.  The unique run-
off coefficient, c, is the product of three factors, each one having some
correlation with the degree of urbanization given to the watershed.  The
presented general rational formula is related to the other rainfall - run-
off relationships derived by Snyder and Horner - Flynt.  Results from the
formula are compared with those obtainable by the Chicago method.   Modi-
fications by urbanization are graphed.   Variability of rainfall frequency
is attributed to topographic and urban conditions.

Stream runoff, as a result of torrential rainfalls, was analyzed on the
basis of the data recorded by Polish hydrological gaging stations.  The
maximum runoff, as a result of a torrential rain is very different from
a runoff formed by spreading rains.  These 2 types of rain runoff cannot
be expressed by a single formula common to these 2 phenomena.  The peak
rate of storm runoff increases with the growth of water basin and can be
well represented by a definite monotonic function, whereas the peak run-
off from a spreading rain increases with an increase in the water basin
area, according to a definite parabolic function.  The study also shows
that under the same physiographic conditions the peak rate of a storm
runoff in small basins is greater than that from spreading rains.   In
evaluating the runoffs from their corresponding rainfalls the Pagliari
formula was adapted as the most suitable for the hydrogeological condi-
tions prevailing in the Polish areas.

Summaries are presented of work concerning peak floods for urban areas
and of a recent study concerning watersheds  in Houston, Texas.  Increased
urbanization results  in increased peak flows and accentuated high and low
flows.  Equations presented show that peak flows may be expected to in-
crease from two to four times that of the flow from the undeveloped water-
sheds, depending upon the type of channel improvement, amount of vegeta-
tion in the channel,  and the type of secondary drainage system.  The
capacity of the secondary drainage facilities may have a limiting effect
on the peak discharge.

This study is concerned with statistical parameters of precipitation  and
runoff and the interrelations between corresponding parameters.  Three
processes are considered:  the input process (mean annual effective pre-
cipitation) , the transformation process (basin storage), and the output
process (mean annual runoff).  The input is assumed to be a pure-random
series with known statistical parameters.   The transformation is char-
acterized by an exponential recession curve with one parameter.  With
these assumptions, equations are developed expressing statistical para-
meters of the output for any simulated series,  which are analyzed for
their moments.  The type of distribution of the output is also established,

fields, and to inform him of the sources of further knowledge.  The first
subsection deals with rainfall measurement, the basis for all hydrologic
and hydrometeorological work.  The second treats the physics and hydro-
dynamics of rain, including the artificial inducement of precipitation.
The third subsection, on the synoptic meteorology of rain, includes trop-

tation forecasting.  The next subsection details space-time relationships
of rainfall.  The last subsection, on design applications of rainfall
data, includes frequency analysis, which is utilized in designing urban
storm sewers; storm transposition; predicted maximum precipitation; and

lent joint distribution of storm rainfall depth and duration to generate
sequences of lumped storms which retain the stochastic features of the
historical storm data.  The prescribed total storm depths are then dis-
tributed over their respective durations by using a special type of urn
model in such a way that the short-time-increment rainfall sequences
within synthetic storms possess, on the average, the same serial corre-
lation and percentage mass characteristics as their historical counter-
parts.  Probability distributions and storm characteristics are obtained
from 10-min summer rainfall data for a period of 5 years at St. Johnsbury,
Vermont.  These sequences are extended synthetically, and the character-
istics of the synthetic storm are shown to agree adequately with the
historical attributes.  Not only does the model give valid results, but
it does so quickly, since it is possible to compile the necessary compu-
ter programs and then generate 15 summers of lumped storms or 5 summers
of 10-min data in 3 minutes.

A two-soil-moisture-reservoir model is  developed  to improve  the estimate
accuracy of a  runoff-volume-prediction  model.  Soil moisture  accounting
in the  two  reservoirs is an  intermediate step  to  runoff prediction.  A
decay-type  function  describes the moisture  depletion between  days  of
rainfall.   The moisture depletion constant  in  the  function varies  by
season  with soil moisture, pan evaporation,  and mean daily temperature.
The  runoff-prediction equation relates  runoff  to  rainfall and soil mois-
ture  at the beginning of the storm.  Computed  runoff volumes  are compared
with  values  observed on a 3-acre native grass-meadow watershed for an 11-
year  period.  Accumulated computed amounts  for the period agree within
1% of the accumulated observed amounts.

Sources of error in defining areal rainfall on a storm basis include the
instrumental error, sampling fluctuations over the area, and network
density.  Analysis of dense rain gage data show the magnitude of the
errors resulting from the natural variability of rainfall.  Except for
one watershed in Arizona, the coefficient of variation, based on a
sample of storm totals from the individual gages in various size areas,
remains relatively constant with increasing area for a particular storm.
The error due to rainfall variability over the area is probably the
most important and must be considered in experiments which attempt to
resolve small-area hydrologic problems.

 A study of the problem in surface drainage of highways deals with peak

 it possible to translate the rainfall input into a runoff hydrograph.
 It was possible to describe a time pattern of rainfall intensity by means
 of an incomplete beta-function.  A two-parameter, log-normal, distribu-
 tion function was a suitable descriptor for all necessary probability
 distributions.

-------
A set of differential equations has been obtained for the overland runoff
from an arbitrary catchment when the rainfall excess over the catchment
is known as a function of space and time.  An analytical solution is
given for a steady rain of finite duration.  The differential equations
obtained are also solved analytically for a moving top-hat storm over a
plane catchment, and the maximum depth is obtained explicitly as a func-
tion of the storm duration and catchment length.  The results for all
plane catchments with a given resistance formula are reduced to a single
curve.  It is found that the depth is increased if the storm moves down-
stream and decreased if the storm moves upstream the slower the storm
the greater being the change.  Finally, it is shown that all the results
apply qualitatively to open channel flow where the kinematic wave
approach is suitable.  If the lateral inflow replaces the rainfall ex-
cess, it is found that the form of the curve describing the variation
of depth with time is a function of the cross-section geometry but is
qualitatively similar to the overland flow curve described above.

AVERAGE ANTECEDENT TEMPERATURES AS A FACTOR IN PREDICTING RUNOFF FROM

Identifiers:  *Elevation-temperature relationships.

Rainfall-runoff relations in New England and New York have been shown to
vary widely from basin to basin in a manner related to average basin
latitudes and elevations.  Station elevations and latitudes have been
shown to be related to average temperatures.  Average monthly and annual
temperatures were computed for each basin sampled and average weekly
basin temperatures estimated.  These weekly temperatures were used to
derive an index of average antecedent basin temperature based on a
logarithmic recession.  Two rainfall-runoff relationships were derived
in which the index of antecedent basin precipitation, the index of
average antecedent basin temperatures corresponding to the season of the
storm, the average annual basin temperature, storm rainfall, and storm
runoff were used.  One of these relations applied to the spring and
summer, the other to the fall and winter.  Testing showed that a large
part of the variation in the rainfall-runoff relationship had been re-
moved.  It was concluded that average basin temperatures can be used
with profit in computing runoff in New England and New York.

Data from a 50-storm sample on two dense networks in Illinois were used
to investigate the time distribution of 1-minute rainfall rates in warm-
season storms.  Absolute and relative variability were analyzed for point
and mean rates on areas from 25 to 100 square miles.  Several variability
measures were employed including sequential variability that uses both
the magnitude and the sequence of rates in characterizing the time dis-
tribution.  Since the variability parameters were found to fit closely
a log normal distribution, probability distributions were constructed
to define interstorm variability relations.  Both absolute and relative
variability showed a wide range within and-between  storms, and between
areas of different size.  Little difference in variability properties
was noted between rain and synoptic weather types associated most fre-
quently with warm-season storms.  No evidence of regular oscillations
in the time distribution of rainfall rates in convective storms was
shown by lag correlation analyses.

 A 29-storm sample of 1-minute rainfall rates was obtained with an Illinois

 of 1952 and 1953.  These  gages were equipped with enlarged orifices and
 6-hour charts to provide  nearly instantaneous spatial patterns of rain-
 fall intensity on the network.  The data were used  to determine quantita-
 tive estimates of rainfall rate gradients, sampling errors in the mea-
 surement of mean areal rates, and spatial correlation patterns.  The de-
 rived relations are considered  first  approximations for midwestern warm-
 season storms.  It was concluded that  the spatial variability of rainfall

rates is frequently so great within and between convective storms that
the rain gaging equipment and operational requirements for accurate rate
measurements may be prohibitive for most users when sampling areas are

use of radar in combination with recording gages be investigated as a
possible solution to the measurement problem.

type, and other factors on spatial correlations were studied.  Correla-
tion decay with distance used to indicate sampling requirements was
greatest in thunderstorms, rain showers and air mass storms.  Conversely,
minimum decay occurred with steady rain and the passage of low pressure
centers.  Seasonally, the decay rate is much greater in May-September
storms than in cold season precipitation.  Sampling requirements are
extreme in measuring rainfall rates; thus., assuming a minimum acceptance
of 75% explained variance between sampling points, a gage spacing of 0.3
minutes is needed for 1-minute rain rates compared with 7.5 minutes for
total storm rainfall in summer storms.

Correlations between yearly cycles of rainfall and also runoff, for
stations in the Pacific coast region of U.S.A. were obtained from cross-
analysis of the monthly records.  It was found that for stations within
1000 km of each other the precipitation cycle was virtually the same,
and  that there was a similar although less coherent relation for the
runoff cycle.  It was also found that the yearly temperature cycle was
highly correlated with the yearly rainfall cycle but that the yearly
cycle in atmospheric pressure appeared related to the rainfall cycle
only through the temperature cycle.

 This section outlines current uses of hydrologic data and methods of
 solution of urban water problems and needs.  Stormwater drainage is
 emphasized, and the utilization of urban hydrology  in the areas of
 flooding, water supply, pollution, airports, and expressways is mentioned.
 The first subsection, involving qualitative descriptions of urban storm-
 water runoff, explains the hydrologic cycle in terms of runoff-producing
                                 257

-------
storms in order to aid engineers in designing collection and disposal
facilities for stormwater.  The next subsection on the quantitative  de-
termination of urban stormwater runoff includes empirical formulas for
determining design storm drain discharges, the rational method, correla-
tion studies of rainfall and runoff, the hydrograph method, the inlet
method, and the hydraulics of inlets and gutter flow.  The next three
shorter subsections deal with urban flooding, water supply, and pollution
from inadequately treated wastes.   Subsection VII explores the objectives,
hydrologic data, subsurface and surface drainage of airports, and Sub-
section VIII concerns the hydrology of urban expressways.  (See abstract

Storm rainfalls on 9 catchments in Victoria, Australia wer.e analyzed
for rainfall-runoff relationships and 137 loss rates were derived.
Loss rate is defined as the average rate of potential infiltration loss
to surface runoff during the supply period of a storm.  Relationships
between loss rates and some hydraulic factors of the drainage basins
were calculated.  Frequency distributions and seasonal variations of
loss rate were calculated and compared with U.S. and other Australian
rates.

The process of conversion of rainfall excess into surface runoff is
studied by treating drainage basins as lumped systems.  The rainfall
excess is considered as inflow and the surface runoff as outflow.
Making use of the equation of continuity, a differential equation used
with, field data indicates that the system behavior is nonlinear but
can, however be treated as linear by approximation in the case of major
floods.  The proposed equation is verified by applying it to observed
storms, and the results are found to be very encouraging.  This method
of approach provides considerable scope for an analytical treatment of
rainfall excess-surface runoff relationship.

 Prediction equations have been derived for forecasting runoff volume
 for regions within the Province of New Brunswick.   Five basins were
 selected so as to provide a regionally representative distribution
                                259

-------
over the province.  The prediction equations are based on the storm
rainfall, antecedent precipitation index, base flow, and week number in
which the storm occurred.  Statistical methods were used to obtain the
least-squares multiple linear regression equation, correlation coeffi-
cient, and the standard error for each of the techniques used for the
watersheds.  The number of storms varied from 8 to 23 for the basins
studied.  The standard error of the optimum prediction equations for
runoff ranged from 0.065 inches to 0.212 inches and the multiple cor-
relation coefficient (R) varied from 0.556 to 0.963.  Results of the
regression equations developed for one basin were extended to a neighbor-
ing basin of similar hydrological characteristics, but with only recent
streamflow records.

analysis, Storage,  Sediment yield, Water temperature, Water pollution.
Identifiers:  Urban hydrology.

The effects of urbanization on hydrologic factors are discussed and
rainfall-runoff relations of urbanized and unurbanized watersheds are
compared.  Urbanization increases the amount of impervious area in a
watershed so that the intensity and amount of runoff increase and peak
discharges occur sooner.  Sediment yields are 10-100 times larger in
urbanized watersheds, water quality decreases, water values usually de-
crease.  Hydrographs, frequency curves,  and sediment yield-discharge
curves, are used to show typical effects of urbanization on streams.

-------
A simplified, mathematical model of the surface runoff component of
streamflow response to storm rainfall was developed and programmed for
digital computer solution.  The model uses an infiltration component
based on an equation by Philip to determine rainfall excess, which is
transformed by a linear basin-response function to simulate the flood
hydrograph.  An objective-fitting procedure that emphasizes the simula-
tion of peak-discharge rate was used to identify optimum model parameters
in a pilot study of a 5-sq mi drainage basin in North Carolina.  Split-
sample fitting and testing showed that predictive capability varied for
3 samples of flood events.  Results of simulation for 2 test samples of
pre-1948 flood events showed reasonable correspondence between simulated
and observed flood peaks.  The post-1948 test sample showed wide scattering
between simulated and observed flood peaks.  Sensitivity analysis of
objective-function response to parameter incrementation showed that
antecedent moisture accounting grossly controlled the results of optimiza-
tion.

The author  compares various methods of deriving hydrographs for urban
drainage studies, and explains why the lag and route method is superior
to the unit hydrograph.   Computer use is suggested to aid in estimating
runoff from pervious areas and to help integrate characteristics of
rainfall into calculated  flows and simplify  the problem of determining
frequency of computed peak flows.  This method would aid testing of the
RRL procedure described in the original paper.

-------
The Committee on Status and Needs in Hydrology investigated research
needs in hydrology and their report is summarized in this article.  They
conclude that within hydrology, water quality requires increasing atten-
tion.  Also, the position of biological rather than physical processes
of the hydrologic cycle needs to be studied, and efforts should be made
to research chemical, physical, and biological phenomena associated with
flow in permeable media in and near the ground surface.  A list of sixty-
three research topics, compiled by the Committee, encompass these points.
The order of the list conveys the relative importance of needed research
in the overall field of hydrology, rather than a judgement of intrinsic
scientific merit.  Rainfall-runoff relations, areal distribution of
storm precipitation, hydrologic systems analysis, unit-hydrograph simu-
lation, and processing of hydrologic data are examples of topics listed.

Identifiers:  *USSR, Carpathian Rivers.

On the basis of discharge and precipitation data recorded at several
gaging stations of  the Carpathian Rivers, the rainfall-runoff losses
were  analyzed by using the standard technique of subdividing a river
discharge into the  total and basic parts.  Flood frequencies, runoff
coefficients, precipitation, and water loss volumes were calculated and
expressed by charts and tables.   The analysis of runoff coefficients
indicates an initial loss of water equal to a layer of 40-50 mm in thick-
ness  for summer floods and 10-15 mm for spring and fall floods.  The
hydrologic  data record at the Transcarpathian gaging station shows the
greatest losses (as much as 90%)  after isolated rainfalls in river ba-
sins  of small areal extent.  The smallest losses occur after long in-
tensive rainfall or after a long rainfall period.   The majority of rain-
falls characterized by maximum discharges have high rainfall-coefficient
values  (0.60 - 0.90) and occur during the spring and fall months.

orological data, Surveys, Data processing, Water quality.
Identifiers:  *Urban hydrology, Storm sewers.

The article focuses on data needs, data devices and data networks.
Primarily aimed at improvement in design of storm drainage, an intensive
study was made of the data requirements for analyzing rainfall-runoff-
quality relationships and of suitable data collection instrumentation,
with consideration of the types of networks required for the collection
of adequate data.  Suitable data collected with properly coordinated
instrumentation in networks representing a variety of climatic, topo-
graphic, and land-use conditions, are virtually non-existent.  There
are very meager amounts of performance data with which existing or pro-
posed storm drainage facilities can be checked or designed.  Transfer
of data findings between metropolitan regions is a central and primary
objective.  Recommendations centered on hydrologic information needs
are related to storm sewers.  The replacement value of existing storm
sewerage systems in the United States is at least $22 billion, and it
is estimated that an average of about $3.5 billion per year will be
spent on construction of new storm sewerage systems over the next sever-
al years.  The plan recommended for a minimum national program of urban
storm drainage research would cost on the order of 1/3% of this average
annual construction cost.

Because the 'rational method'  of designing urban storm- drainage facili-
ties has substantial liabilities, new design procedures are discussed and
the urgent need for more  field stream gaging data is stressed.  The
limitations of the rational method consist mainly of the weaknesses of
                                 263

-------
projecting standard values of the rainfall-runoff relationship over wide
geographical areas, the use of too many standardized assumptions, and
using the same runoff routing methods in too many dissimilar situations.
Suggested improved design methods would use on-site gaged rainfall-runoff
relations to determine flow probabilities in mathematical models so that
the optimum drainage system for each particular case may be designed.
Presently there are no gaging programs of sufficient scope in operation.
Other suggestions include the use of surface detention to flatten runoff
peaks, storage of urban runoff for water supply use, or use of urban run-
off as a source of recreational water.

Urban changes, largely social and economic, that affect urban hydrology
are discussed in a survey and bibliography of urban sociology and recent
urban history largely consisting of quotations and reviews of non-engi-
neering and non-hydrological literature.  Urban expansion is considered
largely a function of development of new forms and trends of use of high-
speed urban transport.  The urban areas of the country are growing rapidly
with trends of increasing urbanization added to increasing growth of
suburbs.  Urban problems of crowding, water supply, waste disposal, and
general environmental quality are growing even faster than the cities.
The need for comprehensive planning rather than solving single problems
such as waste disposal or water supply is stressed.  The environment of
cities is a function of all social and physical factors.  Hydrological
problems can be solved only as part of the total environmental problem.

Activities in urban water resources research by ASCE in 1967-1968 are
reported.  The objective of the research is to provide guidelines for
initiating and expanding a program of long-range studies in urban water
problems.  Considerable attention was given to storm drainage to arrive
at mathematical descriptions of the rainfall-runoff relationship, to
predict pollution loads, and to develop methods of planning water quan-
tity, quality, and drainage development.  Data collection system design
and data requirements are discussed.  Systems analysis, statistical
studies, and model studies are being initiated.  Considerable attention
was given to research needs in political, economic, social, legal, and
related aspects of urban hydrology.  Appendices contain technical and
feasibility studies of modeling, flood damages, non-hydrological aspects,
research needs, systems engineering, and economics.

-------
characteristics of watersheds, both rural and urban, and it is urgent to
know the character and extent of the changes and how they affect plans
for development.  Numerous field studies designed to evaluate the effect
of specific watershed changes by comparisons between watersheds have
been in operation for sufficient time to build up a significant length
of record.  New methods of computer simulation of watersheds have reached
a stage of development to offer an attractive tool for attacking the
problem in new ways.   The effects of the changes can best be evaluated
when the entire performance of the watershed is understood in detail.
Then all of the physical processes can be followed and the performance
of the watershed can be simulated by numerical or analog techniques
which correspond to the physical processes.   Watershed changes produce
effects on both the amount and the quality of streamflow.   The topics
discussed include model studies, land treatment in rural watersheds,
flood control structures, rural pollution, the effects of urbanization
on peak flow, the effects of urbanization on water yield,  and urban water
quality changes.

 Water balance methodology  (including the Thornthwaite potential evapo-
 transpiration) and water balance models are applied to the Raritan River
 basin in New Jersey.  In order to gain some understanding of hydrocli-
 matological processes and  interrelationships associated with urbaniza-
 tion of drainage basin.  The precise objectives are:  to compare and
 contrast selected Thornthwaite water balance components as calculated by
 several more or less  'standard' techniques; to demonstrate that poten-
 tial evapotranspiration and water balance models can be utilized as
 hydroclimatological controls to obtain first approximations of the con-
 sequences of land cover type change, or urbanization within a river basin;
 and, to explore generated water balance data based on the assumption of
 the transformation of a watershed from rural to urban.  Calculated run-
 off takes into account the monthly and seasonal variation of precipita-
 tion and soil moisture storage as well as energy availability for evapo-
 transpiration loss.  Measured runoff not only includes the climatic
                                 266

variation but in addition the effects of land use change.  He,nce, the
differences between calculated and measured runoff overtime should be
a measure of the effects of land use change oil runoff.

in the rainfall-runoff relationship is explored generally, based on data
from small agricultural watersheds.  Infiltration in computations of run-

jects such as urban drainage, airports, etc. and also in relation to
larger watersheds.  Infiltration indexes, which express infiltration- as
an average rate throughout a storm, are explained in another subsection,
and lastly, some forecasts are made regarding future research in infil-  .

The two largest runoff-producing storms for 10 yr of records, the first
in 1964 and the second in 1967,  recorded on the Walnut Gulch Experimental
Watershed in southeastern Arizona are analyzed and compared.  Both storms
were non-frontal thunderstorms which produced peak discharges on the order
of 1500 cfs per sq mi; in 1964  from a 2000-acre subwatershed, and in 1967
from an 84-acre subwatershed.  During the 1967 storm rainfall of 3.35
inches in 45 min was recorded  at one point on the watershed.  Approximately
18 acre-ft of runoff was produced on the 84-acre subwatershed in the 1967
storm.  Runoff-producing rainfall lasted for less than 60 minutes for both
storms.  For both storms, runoff per unit area decreased with increasing
subwatershed size because of the large transmission losses in the ephem-
eral channels and because of the limited areal extent of the runoff-pro-
ducing rainfall.

Current practices in urban hydrology, storm drainage, and flood plain

only limit solutions to present problems but contribute to future prob-

ties to flood plain zoning.  One alternative to the present unsatisfac-
tory state of management is to establish a program responsive to all seg-
ments of the population.  Major limitations of present practices in en-
gineering and design are deficiencies in knowledge of urban hydrology,
lack of analyses of accumulated data, and ineffective use of data for
producing optimum designs of integrated drainage systems.  Problems of
urban drainage are primarily institutional.  Enabling legislation is
needed for management of water in entire metropolitan areas by a single
authority.  Programs on federal, state, and local levels for correction
of deficiencies within present flood plains and drainage systems need
development to serve existing communities as well as those that may
emerge in the surrounding area.

The effects of the physical factors responsible for the transformation
of rainfall excess into direct runoff were simulated by the action of a
conceptual nonlinear reservoir.  A nonlinear differential equation of
the basin response was derived.  Because no analytical solution for the
system response equation existed, solutions were found by means of an
electronic analog computer and a numerical method.  Model parameters
were found to be correlated with basin, main channel, and rainfall
characteristics for seven east central Illinois basins.  The consistency
of the results obtained from an analysis of storms over those basins in-
dicated that the proposed model could be adopted for nonlinear simulation
of the hydrologic system response.

The paper describes a detailed experimental-numerical investigation of
the concept of partial area contributions to storm hydrographs.  A com-
puter solution of a numerical flood routing technique was used to iso-
late the time-spatial distribution of local runoff entering the main
channel of a small watershed.  Extensive experimental information col-
lected in the vicinity of the 619 ft length of second order stream pro-
vided a means of interpreting these land-phase hydrographs.  Analysis of
a series of storms showed that only a small portion of the watershed
ever contributed flow to the storm hydrograph.  The contributing area
was found to be a function of the storm duration and intensity and,
rather than being uniformly distributed along the length of the channel,
it existed in the form of localized zones of intense contribution.  In
a given storm, the contributing area was found to fluctuate with changes
in the rainfall intensity.  During periods of low intensity, most of the
flow came from channel precipitation and rain falling on the wet areas
surrounding a series of seeps.  If a period of high intensity occurred,
flow developed through the forest litter on the hillsides and thereby
created a larger contributing area.  No interflow in the soil mass above
the water table was encountered.   A rapid response of the groundwater
at some points along the channel, however might have been interpreted as
interflow if extensive measurements had not been taken.   The behavior of
the watershed was quite logical when the fundamentals of the individual
processes were considered.  The results of the study illustrate that
there is a need for a reevaluation of some of the traditional methods
used for runoff computations.  Further, any parametric model developed
for the synthesis of hydrologic events should be able to reflect partial
area contributions.

Analysis of the point rainfall data in Calcutta, India for 23 yr yields
a procedure for arriving at the relationship between the average inten-
sity of excessive rainfall, the corresponding duration the rain continued
to fall at the average rate, and the frequency with which these combina-
tions of intensity and duration of such storms occur.  Probability
methods based on annual maximum events and partial duration series, and
mathematical and graphical curve fitting, based on frequency analysis,
are employed for developing the relationships.  Intensity duration fre-
quency relations are expressed in tabular and graphical forms and as
mathematical equations.  The various methods do not give exactly identi-
cal results, and discretion must be used to choose between them for
application in the design of a storm sewer system.  No particular method
can be considered as the best for rainfall frequency determination.

The floods of January 1969 in south-coastal California provide a timely
example of the effect of urban sprawl on flood damage.  Despite record
breaking, or near record breaking, stream discharges, damage was minimal
in the older developed areas that are protected against inundation and
debris damage by carefully planned flood-control facilities, including
debris basins and flood-conveyance channels.  By contrast, heavy damage
occurred in areas of more recent urban sprawl where the hazards of inun-
dation and debris or landslide damage have not been taken into considera-
tion, and where the improvement and development of drainage or flood con-
trol facilities have not kept pace with expanding urbanization.

A statistical analysis of rainfall records is used to develop a computer
model for generation of a sequence of short period rainfalls.  Time inter-
vals between rainfalls are generated by sampling from a frequency distri-
bution fitted to historical data.  The model also uses a first order
Markov process in addition to random sampling from a frequency distribu-
tion in order to obtain the rainfall durations.  Rainfall depths are
obtained by sampling from the joint distribution of rainfall depths and
durations.  Model parameters are based on meterologic conditions of the
Auckland area, and all statistical tests were performed at a 5% level of
significance.  The model produces comparable time intervals between storms
and a linear correlation between rainfall depths and durations, but ex-
treme values of rainfall depths and durations are absent from the gener-
ated data.

A commercial clearcutting was made on a 74-acre gaged watershed on the
Fernow Experimental Forest; skidroads were loggers'  choice—without
limitations as to grade or provisions for drainage.   After-logging in-
filtration rates in the watershed remained well above maximum rainfall
intensities except on portions of the skidroads.  Overland flow occurred
only from the skidroads; it resulted from the combination of rain directly
on the skidroads and interception of subsurface flow by the road cuts.
Increased storm runoff in the growing seasons—up to a maximum of about
1/2 area-inch in any one storm—was largely the result of decreases in
field-moisture deficiency rather than changes in the proportions of sur-
face and subsurface flow.   This study indicates that, in judging hydro-
logic condition of logged areas, perhaps  as much emphasis should be
placed upon road conditions and forest-floor disturbance as upon the
amount of timber cut and condition of the stand.

MODELING THE RUNOFF CHARACTERISTICS OF AN URBAN WATERSHED BY MEANS OF AN

In the synthesis of hydrograph characteristics of small urban watersheds,
the distribution of the water among the various phases of the runoff pro-
cess is attempted by the concept of 'equivalent rural watershed.'  For a
given input into both the models, the outputs must be identical.  The
hydrograph of outflow from an urban watershed is obtained by chronologi-
cally deducting the losses due to interception, infiltration, and de-
pression storage from precipitation on the equivalent rural watershed
and then routing it through the surface and channel storages.  This is
being approached by computer simulation.  Testing and verification of
the basic mathematical model is being done by using observed rainfall
and runoff data from well-instrumented runoff areas.  Coefficients re-
presenting interception, depression storage, and infiltration are deter-
mined by the trial and error process on the analog computer in such a way
that the outflow hydrograph predicted by the model is nearly identical to
the measured prototype hydrograph.  Relationships between these coeffi-
cients and various urbanization characteristics or parameters are estab-
lished.  Sensitivity studies which investigate the significance of each
of the watershed coefficients on the outflow characteristics are also
undertaken.

 L. H.  Watkins:  The  author  contends  that there  are  two misconceptions
 about  the  RRL  hydrograph method:  1)  the method does  not currently  assume
 uniform  proportional depth  in  the whole  sewer system; and,  2)  the routine
 technique  as applied to  an  areal/time  calculated  hydrograph is  not  illogi-
 cal.   The  use  of  computer service is  advocated.
 E.  J.  Sarginson and D.  E. Bourne:   In reply to Watkins'  comments,  the
 authors  insist that their analysis  can be  modified to allow for variations
                                  273

-------
in proportional depth from pipe to pipe.  They  further  contend that the
method they have proposed separates the effects of  ground  and pipe stor-
age, and the resulting hydrograph simultaneously  gives  the attenuation
in the peak discharge and the delay in the time of  its  occurrence  re-
sulting from the combined effects of overland flow  and  flow in the sewer.

This paper considers phenomena which modify a rainfall hydrograph for an

are satisfied by existing design methods.  The theory presented accounts
for phenomena concerned.   A method for analysis of existing urban rain-
fall and discharge records is given.   This design method was developed
with the hydrograph based on a standard storm which is successively
routed over the ground and through a sewer, assuming a linear storage-
flow relation for each.

M. V. King:  The author disputes certain parts of the paper by D. E.
Bourne and E. J. Sarginson.  He corrects the misconception that the
equation i=e~3/4/4 is the Meteorological Office equation, and he argues
that storm runoff should be considered with regard to time of flow through
the sewer.  He holds that the authors' rainfall hydrographs are valid
only if the drainage area had zero time of  concentration.  He exposes the
weakness of the authors' hydrograph method, and he explains and defends
his proposed method.
E. J. Sarginson and D. E. Bourne:  Replying to King's criticisms, they
dispute his assertion that their rainfall hydrographs hold only if the
drainage area had zero time of concentration.  They also do not consider
                                 274

The  data  for this study  were taken from four watersheds with varying de-

approach  adopted was  the linear (time  variant,  lumped)  system analysis.
The  conceptual linear systems considered in the analysis of the data were
the  single linear reservoir model, the double routing  method, the  Nash
model,  and the single linear-reservoir with linear-channel model.   The
single  linear reservoir  model was selected to simulate the rainfall-run-
off  process on small  urban watersheds  (less than 5 square  miles) based on
the  larger watersheds (between  5 and 20 square miles).  The relationship
of the  degree of urbanization and the  time lag,  the magnitude of  the. peak
discharge,  and the  frequency of peak discharge were studied. Studies will
be continued with linear models and,  in addition, nonlinear models will be
considered in the hydrologic simulation of the larger  watersheds  in order
to develop design methods and criteria for predicting  runoff from  areas
with varying degrees  of  urbanization.

 volution relationship for approximating the rainfall-runoff phenomenon
                                 275

-------
for an urban drainage basin.  A solution for the transfer function  of  the
convolution relationship is obtained by employing discrete mathematics
similar to the Wiener-Hopf equation.  The solution is obtained, based  on
the restraints of the physical system by linear programming.  In  this  in-
vestigation, the hydrologic system is analyzed as a truly linear  system.
Recorded rainfall intensity is the input of the system, and recorded run-
off the output.  A major concern of the study involves the effects  of
antecedent moisture conditions on the transfer function.  Results are
presented which substantiate the use of the proposed linear model as an
approximation to the hydrologic system.  Generalized transfer functions
are developed for each basin and tested with independent events.  Ante-
cedent moisture conditions are shown to have a definite predictable ef-
fect on the transfer function, and rainfall events are classified with
an antecedent moisture condition criteria in order to select the proper
transfer function for the event.   Comparisons are made with more conven-
tional hydrologic analysis.

The Water Resources Division of the U.S. Geological Survey is  currently
expanding its role in urban hydrology as rapidly as possible to meet new
demands.  Almost since the first stream gaging stations were established,
more than 80 years ago, water resources data have been collected  in urban
areas.  Today, some data are available for every one of the 222 standard
metropolitan areas in the United States.  In addition to the collection
of basic data, the Water Resources Division has conducted  studies either
within or including urban areas.  These have resulted in numerous reports
published in the Survey publication series and in outside  technical jour-
nals.  In recent years, the emphasis of these studies has  been on the
assessment of changes in the water resources caused by urbanization.  Storm
drainage today is still largely designed on the basis of the empirical ra-
tional formula using rainfall intensity modified by a coefficient of runoff,
The inefficiency of this method is well recognized.  Greater knowledge of
the part of the hydrologic cycle involving rainfall-runoff relations in
urban environments is needed.  A study, currently under way, will consider
the data needs for urban runoff studies, appraise available and needed in-
strumentation for collection of these data, and advise on  types of networks
for collection of these data.  The study is for design of  pilot areas.

The  effects  of intensive urban  development on  direct runoff to East
Meadow  Brook,  a southwardflowing  stream in central Nassau County,  N.Y.,
during  the period  1937-66, are  described.   The special  objectives  of  the
study were to relate  indices of urban  development  to increases in  the
volume  of annual direct runoff  to the  stream;  to compare  hydrograph fea-
tures at different periods during the  transition of the drainage basin
from rural to urban conditions; and to compare the rainfall-runoff rela-
tions for periods  before and after urban development.   Periods of  housing
and  street construction in the  drainage basin  correspond  to 3  distinct
periods of increased  direct runoff. During each period,  the average  an-
nual direct  runoff increased because of an increase in  the area served by
 storm sewers that  discharged into East Meadow  Brook. The amount of land
served  by sewers increased from about  570 acres in 1943 to about 3,600
acres in 1962,  or  about 530 percent.   During this  same  period, the aver-
 age  annual direct  runoff increased from about  920  acre-feet per year  to
about 3,400  acre-feet per year, or about 270 percent.

A mathematical model for channel networks (represented by directed graphs

makes possible the  simulation of effects of changes in geometric factors
specified by shape  and connectivity,  while keeping a fixed prescribed
temporal and spatial precipitation pattern.  Alternatively, this model
may be used with fixed networks of interest to study the effects of
different types and motions of storms.  The model provides for a discrete
approximation of the distributed network, and transformation relating a
runoff hydrograph to input precipitation.

A simple mathematical model of an urban basin presented in 1962 by the
British Road Research Laboratory is tested on three urban watersheds in
the United States.  The basins are located in Baltimore, Md. and Chicago,
and Campaign, 111.  They contain 0.395,  12.5, and 2290 acres respectively.
The model produces a runoff hydrograph by applying rainfall to only the
directly connected impervious area of the basin.  The basin is described
by a time-area diagram and a discharge-storage relationship.  The peak
discharges of actual and predicted hydrographs are shown for 8 of these.
To apply the model to a basin, the pattern of impervious areas must be
known in detail, as well as the slopes and sizes of all surface and
subsurface drains.

 The size distribution and number of sewered drainage catchments in  San
Francisco, Washington, D.C., Milwaukee, Houston, and Philadelphia are
summarized to provide data for urban rainfall-runoff-water quality
studies.  The 4 cities are in 4 distinctly different regions of the US,
and are different topographically.  The sizes of all sewered drainage
catchments are tabulated, maps show catchment boundaries, and supporting
discussions are presented.  Only the drainage catchments served entirely
by  storm or combined sewers are discussed, and partially sewered urban
drainage catchments are omitted.  The distribution of sewered drainage
catchment size is unique  for each city.  The number of catchments varies
from 42 in San Francisco  to 1,283 in Houston.  The largest catchment
varies from 1,820 acres in Milwaukee to 6,180 acres in Washington, D.C.
The average catchment size varies from 65 acres in Houston to 560 acres
in  San Francisco.  The median catchment size varies from 6 acres in
Houston, to 190 acres in  San Francisco.  In Washington, B.C., drainage
catchments varying in size from 1 to 50 acres account for 46% of the
total number of catchments varying  in size from 1 to 50 acres account
for 46% of the total number of catchments, but their cumulative area
served by sewers.  On the other hand, over 50% of the total District
area served by sewers is  accounted  for by the 5 largest drainage
catchments, which are only 5% of the total of 93 catchments.

Detailed data of the hydrology of  Northwood, a small urban drainage area
in Baltimore, Maryland, are presented.  Northwood is one of the few
sewered catchments in the U.S. that is gaged with flumes.  The 47.4 acre
drainage area is about 4 mi north  of downtown Baltimore in a residential
suburban area.  It contains a 17.4 acre shopping center and 30 acres of
residential development.  Buildings in the residential area are very
uniformly grouped houses with 3-4  houses per group.  The average imper-
viousness of the drainage area is  68%.  Ground slopes average 3%.  A-
weighing bucket rain gage and a Parshall  flume were installed in 1959,
and  the rain gage was replaced with a  tipping bucket gage in 1963.  Both
in the rain gage and stream gage have  recorders.  Runoff is estimated to
be within 5% of actual flow 95% of the time for  flume depths over 4 in.
Reduced rainfall and runoff data for 14 storms,  hourly precipitation, and
daily pan evaporation data  are tabulated.  Hyetographs and hydrographs
illustrate the rapid response of the drainage area.

An example is given of the adaptation of preliminary research data to
the development of new drainage design criteria for a major metropolitan
area.  The new criteria should be closer to the actual needs than the
old rational method criteria.  The Houston metropolitan area, one of the
most rapidly urbanizing areas in the United States, was used to establish
and test new urban runoff criteria.  In order to apply urbanization factor
data to design, the following procedures are followed:  (1) develop the
mean basin length and mean basin slope values from topographic maps;
(2) estimate the degree of development anticipated in the watershed for
                                  284

-------
the period of design;  (3) estimate drainage density for each of the
areas of use; (4) multiply the drainage density by the area for each type
of land use to get total channel length;  (5) determine the basin factor;
(6) from the curves, determine the time to  peak and the unit hydrograph
peak for the degree of development involved; and (7) develop the unit
hydrograph.  A simpler way to use the criteria is to  develop them as
empirical curves of drainage area versus  discharge, of specific use
only in the urban area and for the storm  frequencies for which they are
designed.  Synthetic unit hydrographs were prepared and tested for about
50 drainage areas in the Houston areas.

The feasibility of determining  the  groundwater  contribution  to  stream
flow during periods of  storm  runoff by  continuous monitoring of a
stream's electrical conductance was investigated.   The  groundwater  con-
tribution can be estimated  if stream  flow  and the conductance of surface
water and of groundwater  are  known.   The conductance method  was tested on
                                 285

-------
a 95-square-mile basin in north-central Illinois.  Continuous records
of stream flow, stream-flow conductance, and groundwater stage within
the basin were collected.  A rating curve of base flow versus mean
groundwater stage was constructed, and groundwater discharges determined
from the rating curve were compared with those computed from conductance
data.  The conductance method normally gave a lower estimate of the
groundwater contribution than did the rating-curve method.  However,
analyses of storms which were preceded by extended dry periods resulted
in much lower estimates of groundwater discharge by the rating-curve
method than by the conductance method.  The conductance method offers a
simple alternative for use in areas where observation wells are unavail-
able or where rating curves are difficult to construct.

Urban  development has a  significant impact on hydrologic relations.  The
results of  various studies  demonstrate the type  and magnitude  of many  of
the effects on yield.    These may be summarized  as including:   (1) increase
in total  yield from  stormflow and in annual  discharge;  (2)  decrease  in
base flow of  those streams  that  remain under generally  natural conditions;
(3) modification of  low  flow of  streams influenced by the  importation
of water,  the  use of which  results in discharge  of wastewater.  This
includes  the  increase of low flow in streams that receive  septic-tank
drainage,  or  effluents from sewage-treatment plants, or  from industrial
plants;  (4) decrease  in  recharge to the underlying ground-water basins;
and (5) increase in  precipitation in urban areas and corresponding
increase  in yield.   The  principal effect of  urban development  on yield
is an  increase in direct runoff.  The cumulative effect  of  increase  in
stormflow from urban areas, particularly in  regions of  strip cities  and
the megalopolitan complexes developing in several areas, may be substan-
tial on downstream receiving channels.

The Los Angeles flood control system, comprised of 19 dams, 72 debris
basins, 390 miles of channels, and 1200 miles of storm drains, faired
well during the floods of January and February 1969.  Although the
rainfall intensities did not equal that from the storm of 1938, the
high runoff is attributed to the urbanization of the affected area and
to the quicker delivery of valley flows by the network of storm drains
and collector channels.  The storm experience reaffirmed the adequacy
of the general design of the system.  The effective handling methods
of dams, debris basins, and channels in relation to runoff are discussed.

 The movement of a rainstorm  determines  the  spatial  and  temporal distri-
 butions of the rainfall  over a watershed  and hence  affects  the character-
 istics of the flow on  the watershed.  In  this  study the importance of the
 movement of rainstorms on  the time distribution of  the  surface runoff from
 watersheds is demonstrated-through the  use  of  a laboratory  watershed ex-
 perimentational system.  Experiments  were performed on  the  impervious
 square watershed for  2 rainfall  intensities, 4 surface  slopes, and 14
 rainstorm velocities.   Analysis  of the  mechanics of water flowing on
 watersheds is attempted to  explain the  influence of movement of rainstorms
 on the characteristics of  surface runoff  hydrographs.

Identifiers:  *Urban hydrology.

As the population of the United States is changing from a predominantly
rural to urban society, so the traditional role of the hydrogeologist
is changing.  Needs for this services are reflecting the requirements
of comprehensive water resources management programs.  This trend toward
urbanization is also creating complex water problems and related land
problems.  Comprehensive water resources planning offers a means of
solving these problems and improving the living environment.  Its emphasis
is on alternative management measures that can best be planned and
evaluated by interdisciplinary study teams, teams that should include
the hydrogeologist.   Urban drainage management programs need additional
supporting research in urban hydrology,  and the hydrogeologist can
contribute broadly in planning these research and management activities,
particularly for projects in stormwater  storage, infiltration, and reuse.
Hydrogeologists can also assist in solving engineering problems encountered
during construction of dams, tunnels, reservoirs, lakes, and canals.  The
inadequate communication that now exists between the hydrogeologist and
the planner can be improved by a closer  working relationship.

Identifiers:  ^Chicago,  Illinois.

As part of Metropolitan Chicago's ten-year program to combat water
pollution, a  deep tunnel sewage plant is  being proposed for completion
by 1972 to store excess floodwaters from  severe rainstorms  in under-
ground chambers.  Stormwater runoff will  be prevented from entering
sanitary sewers, and the water will later be released under controlled
conditions.  The estimated cost of  the deep tunnel project  is $750
million, which is much  less than the $3-billion it would cost to con-
struct separate storm and sanitary  sewage systems.  Other proposed pro-
grams include chlorination of all facilities by 1968, elimination of
visible solids by 1969, and construction  of a tertiary waste-treatment
plant in Hanover, 111.  by 1971.

Drilling and shooting operations drove a tunnel borer through sandstone
while an hydraulic-excavator worked in the earth section of sand, clay,
and gravel to complete a sewer tunnel in Akron, Ohio.  The excavator
had a boom-mounted blade dig and then sweep muck to a conveyor that
dumped into a skip on rails.  Hydraulic jacks thrust the excavator for-
ward and steered it laterally and vertically.  Laser beam sightings kept
the machine on course.  Techniques used to bore the tunnel are described

To tunnel and line three oversized utility conduits under a Houston

tunneling when crews were unable to hold the boring rig on the center-
line.  The subcontractor planned to use a rig that was custom-built for
a Dallas storm-drain project.  With the addition of a shield over the
auger, the job was attempted in Houston's soft earth.  After the centering
trouble stopped work, the remaining tunnels were completed by mining with
pneumatic shovels and jacking the liners into place with the subcontrac-

Present and future demands for tunneling are enormous, especially for
construction of rail lines, highways, sewers, and water-lines.  These
demands require that costs be cut and processes speeded up.  Mechanical
tunneling seems to answer these needs, but problems with it remain to be
solved.  Mechanical moles do not run at the high speed desired, and hard
rock often resists machines' efforts.  Other problems cited include:
inadequate muck-handling systems, a need for development of geological
techniques to provide tunnelers with better information as to what is
lying ahead, a need for better rock-mechanics techniques for measuring
subsurface stresses around boreholes and tunnels, and improvement in
methods for supporting tunnels and shafts against cave-ins.  The
following new techniques for tunneling are discussed:  use of surface-
active chemical agents or lasers to weaken the rock face, electron beams
for cutting rock, pulsed supersonic water jets from an air-powered
cannon, and electrohydarulics—a method of converting electrical energy
into mechanical energy.

A mechanical mole is breaking the way for the placement and jacking of a
two-mile sewer project in the Metropolitan Sanitary District of Greater
Chicago (MSD).  Long jacking distances are achieved by overmining a few
inches and using bentonite slurry as a pipe lubricant.  Part of the good
production rate can be attributed to installation of track for mucking
equipment inside the pipe before it is lowered through access shafts to
crews below.  Workings of the mole and jack are explained.  An electric-
gas laser provides accurate control for rapid mining and jacking opera-
tion, as its beam is sloped to follow the required grade.  The laser also
aligns the pipe vertically and horizontally.  District engineers com-

BACM Industries Ltd.  in Winnipeg built the largest and longest sewer
tunnel ever contracted in Manitoba.   This  storm relief project is  de-
scribed in a brochure they  mailed to all residents in the area.   The
basic construction plan involved the sinking of 10 shafts to a depth of
34 feet at regular intervals,  the sewer being  tunnelled outward from
each shaft and connected to form one long  tunnel.  The soft-mining
method was employed,  and no problems were  encountered except for the
high water table created during  spring because of flooding conditions
above ground.  This was overcome by  boxing off the area and using sump
pumps to divert the water until  workers were finished in that area.
Tunneling procedures  used are discussed, including the open cut method
employed for a portion of the storm  relief sewer.

by Lawrence Manufacturing Company, is rapidly boring a six-mile tunnel
out under Lake Huron for water conveyance to Detroit.  Dimensions and
operating techniques for the mole are described.  Called an Alkirk Hard
Rock Tunneler, the rig is unusual because of the 24-in.-dia. pilot bit
and anchor jutting out of its main cuttethead which mounts carbide
cutters. Laser guiding of the mole is used; in effect, the laser beam
controls the machine.  Should something interrupt the beam, or the laser
itself fail to function, four potentiometers act as a holding mechanism
that maintains the mole on the last recorded position for fifteen
minutes.  Completion of the tunnel is expected to be by 1971, but ground
conditions and legal entanglements have placed the project behind
schedule.  It is hoped that the mole will improve this situation.

 The Metropolitan Sanitary District of Greater Chicago  (MSD) has a plan
 devised for  the control  of pollution from storm and combined sewer water
 runoff  — the Chicagoland Deep Tunnel Project.  This plan  would:  cap-

 billion ($.02 billion more than the present sewage treatment facilities'
 cost);  and,  almost completely  remove BOD from the stormwater runoff at
 h the cost of available  alternatives.  The Harza Engineering Co. and
 Bauer Engineering Inc. are the two consulting firms working on the pro-
 ject which may  develop into a $2.2 billion water quality program.  Com-

Fifteen years ago, a Radcliff sewer connection by tunnel was more expen-
sive than a riverside route on the surface.  However, developments in
tunneling made it possible for a tunnel route to provide savings over
the sewer's probable life.  So, a %-mile long sewage tunnel was con-
structed.  Blasting was used for the greater part of the length, and
excavated materials were removed by means of an electrically-driven small
gauge railway.  Instead of employing compressed air for shaft sinking,  a
recently developed boring technique was used.  The method is fully
described along with other construction and installation procedures.

The possible effects of the proposed Chicago deep tunnel urban runoff
retention scheme on the water resources of northeastern Illinois were
estimated by surveying the hydrogeology, surface water hydrology, and
groundwater development of the area.  Chicago has a combined sewer
system, and storm runoff overloads cause discharge of raw sewage to
waterways including recreational areas  of Lake Michigan.  A system of
deep tunnels and protective recharge wells is proposed for temporary
storage of peak combined loads.  The system is expected to release
treated storm runoff at a steady rate,  greatly regulating the streamflow
of receiving streams.  High groundwater heads must be maintained to pre-
vent loss of contaminated water from the tunnels, requiring good ground-
water management practices for the entire area.

described for solving these flooding and pollution problems in the
Chicago area, namely:  Underflow Storage Plan, the Deep Tunnel Plan, and
the Chicago Drainage Plan.  A complete description of the Underflow-
Storage Plan has been presented which will reduce the spillage of pollu-
tants to the surface waterways by over 98.5% and provide the necessary
flood control to handle the 100-year frequency storm.  Recommendation
for the starting of the First Phase of this plan is emphasized, and the

The basic concept of the  Chicago Underflow-Storage Plan for Pollution
and Flood Control is the  use of a pattern of underground tunnels.  These
tunnels would  be sized to provide a linear distribution of storage volume,
and a  conveyance capacity in a single pattern of cleansable tunnels with-
out the necessity for supplemental storage or power development.  All
water  remaining in the underground tunnels after each storm period will
be pumped directly to the existing treatment works.  The underflow-con-
veyance capacity takes advantage of the lowered water levels to be
established in the Illinois Waterway at Lockport for flood control and
improved  navigation.  The basic features of the Underflow-Storage Plan
include:   (1)  18,000 acre-feet of underground storage; (2) a combined
outflow capacity by underflow and overflow of about 43,000 cfs; (3)
sufficient underground storage for any storm having a frequency of re-
currence  up to 100 years.  The  total capital cost of the proposed Com-
bined  Underflow-Storage Plan is estimated to be $650,000,000.

The proposed Chicago deep tunnel plan would  provide temporary storage of
storm runoff from combined sewers to  allow steady  low-volume treatment
and prevent discharge of raw sewage to  surface waters.  The total cost  is
estimated to be 242-446 million dollars.  Operating costs are expected
to be very low because the facility will be  large  enough to use profit-
ably as a peak-demand pumped storage  hydroelectric plants.  Storm runoff
will be only a small part of the total  movement  of water.  The design
and cost analysis of the project are  described briefly.

routes to Rocky Mountain cities of north central New Mexico.  A series
of three tunnels are required for this project.  Geology reports indi-
cated that the rock to be encountered—shale and sandstone—could be
economically excavated by a mole.  Drilling was performed from the
surface along the tunnel alignments at roughly one mile intervals.  A
main concern was whether igneous dikes or sills existed at tunnel eleva-
tion which might preclude using a boring machine.  Results of the explo-
ration program were encouraging and did not indicate presence of igneous
intrusions.  Advantages cited of boring machines over conventional
tunneling methods include:  higher excavation rate, reduction in concrete
needs, fewer personnel requirements, safer operations, reduction in
required supports and in clean-up time.  Disadvantages of mole boring
include:  high initial investment; long delivery period; restriction to
softer rocks; and the requirement for a well maintained ventilation
system, an accurate guidance system, and expert surveying technicians.

Boston Harbor and adjacent waters constitutes a serious hazard to public
health.  The deep tunnel plan is compared in regards to cost analysis
with other pollution control methods.  As a solution to the combined
sewer problem, the deep tunnel plan will be employed so as to eliminate
pollution from waters of the Boston area and to provide a more health-

economical.  Methods of tunnel stabilization, such as grouting and use
of rock bolts, have been improved so that many kinds of rock and diffi-
cult driving conditions can be handled more flexibly.  Savings of un-
lined rock tunnels in time and cost of construction have been demonstrated
by the ready acceptance of this type of tunnel in Sweden, Norway, Australia,
and the United States.   Unlined rock tunnel resistance coefficients can
be predicted by using a rock overbreak parameter.  The important consider-
ations entering into design of unlined rock tunnels are summarized.  The
present method of predicting hydraulic resistance is inadequate.  A study
of tunnel rock overbreak experience leads to a relation between rock over-
break and tunnel size.   This measure of rock overbreak provides a simple
correlation of flow resistance test results based on the fully rough flow

The Greater Chicago area is plagued with recurring water pollution and
flood problems stemming from 3 sources—industry,  wastewater treatment
plant effluent, and combined storm and sanitary sewer overflows.   A
solution to all three sources is the Deep Tunnel Project.   It will cap-
ture stormwater overflows from combined sewers, dropping them through
vertical shafts to a tunnel network.  The polluted water will be  con-
veyed for temporary storage in a large  mined  underground reservoir 800 ft.
(242 m) below the surface.   Preliminary design studies including  project
features, feasibility, costs, performance, and benefits, as well  as oper-
ation, are discussed.  Tunneling methods are  included.

-------
Instead of advancing by having the cutterhead jacked against the face,
as most tunneling machines do, a Detroit hydraulic rig used a reverse
technique.  This mole drilled a pilot hole in the center of the face,
locked in place an anchor concentric with the pilot-drill stem, and
then pulled itself forward hydraulically against resistance of the
anchor.  The main cutterhead and pilot drill advanced simultaneously.
Water and fault zones complicated early stages of work on the water
tunnel, but the contractor hoped to make up time with the new method.
Complete descriptions are given of the structure of the machine, mucking
operations, laser guidance, and the mole's power source.

 The Habegger hard-rock  tunneling machine was used in boring the high-
 pressure water tunnel for  the Juliawerk Tiefencastel Project, Switzerland.
 Experiences in tunneling,  machine operation, and rock cutting are discussed.
 Improvements in designing  cutters and developing cooled cutters are
 described.  The machine steering system and a helium laser directional
 guide held horizontal and  vertical  deviations within 4 cm over 800 m.
 A scraper conveyor system  was modified to successfully leave a clean
 floor while working  in  groundwater.  Comparing mechanical with conven-
 tional tunneling indicated that rock excavation costs are approximately
 equal.  Problems of  what is hard rock in regard to  tunneling machines,
 rock properties for  evaluation of rock cutting, and  wear of cutters are
 covered.

When planning sewerage facilities for large areas, there is now a
tendency to use tunnels in place of trunk sewers, making it feasible
to transport sewage over longer distances.  The author describes a
method for the hydraulic design of such tunnels, designed to be self-
cleaning; and he gives design graphs for convenience.  It is pointed
out, however, that the self-cleaning feature does not necessarily
determine the optimal tunnel area.  Economic considerations may be
the determining factor in regard to the self-cleaning feature, par-
ticularly for larger tunnels.

A tunnel in Edmonton is being produced at  an average  of 120 ft/day.   A
tunnel mole and the use of a laser beam have hastened the procedure.
The  practical limit on the distance the beam can travel depends on
two things:   changes in direction of the line, and the  amount of dust
and fog in the air in the tunnel.  The mole consists  of a set of ro-
tating arms  with cutting teeth and a bucket wheel for catching the
loosened material.  The workings of the tunnel operation are given.

of the area are:  the conveyance tunnels;  and the mined storage reser-
voir, which will convey and store polluted stormwater overflows.  The
Silurian and the Cambrian-Ordovician aquifers, in units of which these.
elements will be located, will be protected from any deleterious ef-
fects of the System by ensuring that a positive hydraulic head, causing
an inward flow, is continuously maintained around the tunnels and the
mined reservoir.  In the Cambrian-Ordovician aquifer, this necessitates
that groundwater levels are maintained by artificial recharge.   Ex-
tensive groundwater studies were conducted to (1) demonstrate the feasi-
bility of aquifer protection by recharge,  (2) determine the needed amounts
of recharge water, and (3) estimate the seepage of groundwater into the
tunnels and mined reservoir.  The studies included field investigations,
analog computer analyses and office evaluation of the collected data and
analog results.  The results indicated (1) the proposed aquifer protection
is feasible, (2) the recharge requirements will vary from 1.4 mgd in 1976
to 6.0 mgd in 2010, and (3) seepage into the tunnels will be small, in
amounts that can be easily controlled.

This plan envisions temporary storage of combined sewer overflows in
a systems of tunnels excavated in solid rock, deep under the City.
After the end of a storm, stored water would be pumped to the surface
where it would be treated to remove pollution before being discharged
into waterways.  Preliminary investigations indicated t-hat aquifer
protection can be provided by a system of recharge wells.  Further
detailed studies, now in progress, include detailed exploratory dril-
ling, controlled aquifer tests in selected zones, pumping tests for
specific capacity in a zone to be tunneled, recharge injection tests,
and analog model analysis.

In Mexico City, an area that once engulfed a lake and inherited the
problems of building on unstable ground, contractors worked to install
a new system of sewers and storm drains.  To prepare for three big
moles that performed the tunneling, deep access shafts were sunk into
the ground that varies from jelly-like volcanic ash to solid rock.  Most
of the contractors adopted variations of the slurry-trench system to
construct concrete walls for the access shafts.  One company used a
method called "controlled flotation," by which the shaft is formed and
concreted in a series of steps—all performed at ground level, and
then it is sunk toward its final position as wall sections are added
on top.  This method is described in detail as are variations used in
the slurry-displacement method.  Several solutions to groundwater prob-
lems are outlined.

A deep tunnel storage plan has been proposed to prevent pollution due
to discharge of wastewater overflows and mixed wastewater and storm-
water from the combined sewers of Boston and adjacent municipalities.
Other methods such as complete sewer separation, chlorination tanks,
and holding tanks were considered, but the deep tunnel system appeared
most economical.  Construction costs were estimated at $66 million.
The proposed system consists of 17.2 miles (27 km) of 33-ft (10-m)
diam deep tunnels in a radial pattern, a pumping capacity of 2,400 cfs
(4,100 cu m/min), and a 45,000-ft (13,700-m) ocean outfall with dif-
fusers.  The system is designed to handle runoff from the 15-year-fre-
quency storm of 24-hour duration within 2 days, without surcharging,
and the maximum recorded storm for Boston if surcharging is permitted.

Factors influencing hydraulic characteristics of small unlined tunnel
cross sections are presented.  Investigations were performed in rock
tunnels constructed by the Helsinki City Waterworks for conveying raw
water.  The length of the Silvola Reservoir entrance tunnel is 1.8 km;
the theoretical cross section is 4:5 sq m.  The length of the Silvola-
Vanhakaupunki raw water tunnel is 7.6 km; the theoretical cross section
is 6 sq. m.  Vertical shafts divided both tunnels into 3 parts, in all
of which cross-sectional measurements and pressure loss measurements
for different discharges were accomplished using measuring weirs and
Siemens Venturi meters.  All 3 tunnels were excavated by the so-called
Swedish method in the most usual type of rock in Finland, composed mostly
of granite and gneiss.

 the variation of areas; (2) the variation of overbreak with tunnel size;
 (3) the relation between the resistance coefficient and the variation of
 area; and  (4) the effect of lining slabs on resistance.

S.V. Chitale and K.S. Rajagopalan comment on Figures 2 and 3 of the
original article.  Fig. 2 shows a plot of resistance coefficients for
unlined rock tunnels, and considerable scatter of data is apparent.
The authors list reasons for this scatter.  Fig. 3 gives tunnel over-
break for various tunnel sizes.  The authors note the difficulty involved
in using this figure to estimate overbreak depth because of the presence
of considerable scatter, and they suggest a way to improve this situation.
David Ellis Wright notes that progress will be made in designing unlined
rock tunnels only if a critical comparison is made of results on proto-
type tunnels.  He lists requirements to be satisfied in order that these
results be of wider design use.  He also.defines terms such as tunnel
size, overbreak, relative roughness, and equivalent sand grain diameter,
rfhich he uses in his commentary on the original paper.  His comments
include opinions on the resistance equation, the relation between re-
sistance and roughness, partly-lined conduits, and data in Table 2 of
the original paper.

The  salient feature of  the New Austrian Tunneling Method  is  a  semi-
rigid lining applied to the rock before it is damaged by  loosening.
The  lining, designed to reach permanent equilibrium after adjusting
to rearrangement forces, may be any  material or combinations of
materials suited to the purpose.  Tunnels should be driven full  face
where possible in a minimum of time.  Practical experience and
                                    314

theoretical investigations have proved that by using the method, rock
surrounding a cavity can be transformed into an effective carrying
member.  Failure by she-ar is the only mode of collapse of a tunnel
lining when the lining extends around the entire periphery of the
tunnel section.  Principles for designing linings based on failure by
shear are explained and proved by model tests.  Some theoretical
analyses of the strength of linings and anchors are presented and a
design method based on data collected on shear failure is discussed.
The effect of contact between lining and rock on tunnel behavior is
examined.  A type of strengthening consists of system anchoring com-
bined with shotcrete, taking advantage of the property of rock to
stabilize by yielding, is described.  A tunnel and an underground
powerhouse constructed in accordance with the New Austrian Tunneling
Method are described.

Preliminary studies showed that a flooded tunnel interceptor system
would be the most advantageous type for an area of St. Louis, Missouri.

 Interceptors were designed  to  carry ultimate peak dry-weather flows
 only,  since the  city has many  combined  sewers.  The  interceptors
 will exclude backwater  from the Mississippi River at low to moderately
 high river stages.  A boring machine  was used for parts of the tun-
 neling during  construction.  Operation  of the system will depend  on
 river  stage, rainfall,  and  the operation of an  interconnected flood
 protection system.  Drawdown of  the wet well at the  terminal pumping
 station will be  necessary periodically  to promote cleansing of the
 tunnels.  The  system is  furnished with  telemetering  devices and
 central controls.

 A growing need for underground  construction exists  in  transportation,
 pumped storage,  pollution control,  and  defense works.   The  rate  of
 growth of tunnel construction is  limited  only by the higher cost when
 compared to above-ground construction.  A substantial  portion  of the
 cost of underground work is  in  the  support and lining  of  the excavation,
 and making this  area more economical  is important.  Any acceleration
 of the rate that support or  lining  can  be placed permits  the use of
 faster tunneling machines and reduces costs.   Gunite,  a pneumatically
 applied cement mortar used in canal linings,  has been  used  with  wire-
 mesh reinforcement in tunnels to  prevent  slaking and spalling  of the
 ground, with good durability and  resistance to abuse.   The  spraying of
 large-aggregate  concrete was only mildly  successful until European
 research with chemical accelerators provided a means of controlling
 the rate of strength buildup of the sprayed material.   Use  of  acceler-
 ators started the changes in application  practices  and furthered the
 acceptance of shotcrete in underground  work.   First used  in combination
 with steel ribs  and wire mesh shotcrete is used more frequently
 unreinforced.
