                            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 discharge, storm sewers, and combined
sewers-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, such as "agricultural runoff",  have
been excluded.

The  present work represents an  effort to index,  expand  and  update the
annotated bibliography,  Storm Water  Runoff from  Urban  Areas, issued  in
April 1966 by the Cincinnati Water  Research Laboratory of the Federal Water
Pollution Control Administration. Among the 573 abstracts presented are 386
not previously included,  which summarize articles dated both earlier and  later
than 1966, so  that the present compilation represents as complete a biblio-
graphic record as possible of storm water articles, up to—and to some extent
including-1968. The 187 abstracts from the 1966 edition were indexed, but
not  otherwise edited or  re-evaluated. For  convenience, the abstracts are
classed in eleven sub-topic categories, and arranged  by  abstract  number
within each  category. Since most of the papers fit into more than one  cate-
gory, the cumulative  subject  index at the end of the volume provides the
necessary access to individual concepts by referring to each pertinent abstract
number. 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  subject  terms). The
most important index terms are marked by an asterisk. The format of  abstract
presentation  follows the  one used by  the Department  of  Interior's Water
Resources Scientific  Information Center for its  periodical,  Selected Water
Resources Abstracts.

Copies of the articles abstracted in most cases can be obtained from research
libraries covering water  pollution  or public health  engineering literature.
Some  are not generally  available and may  be inspected  at the offices of the
Storm and Combined Sewer  Pollution  Control Branch,  Division  of Applied
Science and  Technology, Federal Water  Pollution Control  Administration
(FWPCA),  Department of the Interior, Washington, D. C., 20242. None of the
articles are  available  for distribution  by FWPCA.

Suggestions concerning  the improvement of content and format, or expansion
of subject coverage in future supplements  to this compilation, will be grate-
fully received.

FLUID FLOW MEASUREMENT.
Brit Patent 862,891.

Descriptors:    *Flow   measurement,    'Pipes,
'Tracers, Velocity.

A method is claimed for determining rates of fluid
flow and comparing relative rates of flow under dif-
ferent conditions in pipes, canals, or rivers, by in-
troducing a known quantity of radioactive material
and monitoring the stream to obtain a time-integral
value  of the  effect of the radioactivity during its
passage or transit past a given point (by integrating
the response of a radioactivity detector such as a
Geiger counter). The  method is based  on the
discovery that the  integral  or total number of
gamma or other suitable radioactive rays detected
is inversely proportional to the velocity of flow, but
is independent of the way in which the radioactivity
is spread out along a segment of the fluid stream as
the result of flow conditions.

Descriptors: 'Instrument,  'Storm runoff.  Rain
gages, 'Flow measurement, 'Weirs.
Identifiers: 'Storm sewers. Surface permeability.

The results  of the project's effort to develop relia-
ble rainfall  and  stormwater runoff measuring in-
struments are presented. A depth type pressure
sensing device for measuring the flow at a single
point in a storm sewer, and a sharp-crested sensing
weir for measuring the runoff entering a storm-
water  inlet, have  been developed. It is felt that
these instruments can be employed by other agen-
cies with very few changes. The observation of
widely differing amounts of runoff from storms of
the same frequency, with changes in soil permea-
bility as a factor, is one of the other problem areas
mentioned.

AUTOMATIC CONTROL VALVES,

Water Wastes Eng, Vol 5, No l,pp 43-5, Jan 1968.

Descriptors:  'Automatic control,  'Flow control,
'Instrumentation, Sewage treatment. Hydraulics.
Identifiers: 'Calculations.

Many specialized valves are now incorporated in
the automatic control of sanitary systems and suc-
cessful application of a control valve to  a process
requires complete understanding of the hydraulics
of the system under design.  Design techniques for
control problems involve flow of reagents (pH con-
trol), pipeline losses, inlet losses, outlet losses, and
fitting^ losses. In every case a valve  can be con-
sidered a control of simple flow between two reser-
voirs. A valve may also be considered a variable
orifice.  Derivations  of sizing  equations for (1)
liquids, (2) gases and (3) steam and other vapors
are given. A  table presents typical valve coeffi-
cients for valve types such as butterfly, needle, and
wide  range  V port. Some typical valve  sizing
problems are presented and solved by application
of the equations derived.

TV SEWER INSPECTION,
Robert H. Brindley.
Amer City, Vol 79, pp 87-89, Jan 1964.

Descriptors: 'Equipment, Sewers.
Identifiers: 'Sewer inspection.

The television sewer inspection equipment of the
Hartford, Conn., Metropolitan District is described
in the article. Inspections have proven effective in
locating house laterals, finding sewer obstructions,
and determining condition of sewers.  A crew con-
sists of television operator, forward winch man, and
cable guide man. The camera can best be pulled
through the sewer by a hand winch that has reduc-
tion gears with a pulley and brace mounted in the
manhole. A direct-wire intercom with a talk-back
speaker provides communication and permits the
winch man to keep both hands free. Sewers need-
ing cleaning or flowing over one-third full are not
conducive to TV inspection. Difficulties in the use
of the equipment have been resolved: camera skids
have been modified to prevent fouling of lines; a
more powerful camera light has been installed for
use in  small sewers;  work  has been  rescheduled
when radio frequency interference occurred; and
fog has been moved through the sewers by a porta-
ble blower forcing air into the manhole.

ried out at Anchorage, Alaska, to assess damages
caused by earthquake, covered 600,000 ft of 8- to

MAGNITUDE AND FREQUENCY OF FLOODS
IN SUBURBAN AREAS,
R. W. Carter.

Descriptors:  'Drainage  systems, 'Hydrographs,

Identifiers: 'Suburban drainage, Washington, D.
C., 'Surface permeability.

Suburban development changes two  of the basic
elements that determine the magnitude and timing
of the volume and peak of the flood  hydrograph,
namely  the average  infiltration rate (which  is
decreased  because roofs and streets are impervi-
ous), and the lag time between rainfall excess and
the flood hydrograph (which is decreased because
of storm sewers and improvements to the principal
stream channels). The net effect of these changes
has been evaluated in the vicinity of Washington,
D. C. After analysing the data statistically, it is con-
cluded that for drainage basins larger than 4 square
miles in  the Washington area the maximum effect
of complete suburban development on flood peaks
of any recurrence interval is expressed by the ratio
flood discharge (suburban): flood discharge (un-
developed )=1.8.

Identifiers: 'Interceptor sewers, Cincinnati (Ohio).

A description is given of the system installed at Cin-
cinnati, Ohio, to detect when overflows occur from
the sewers as a result of clogging of the interceptors
with solid materials during normal  dry-weather

tor and the signal is transmitted to the telephone
exchange. It is hoped by this means to reduce pollu-
tion of the various creeks within the metropolitan
area.

An illustrated description is given of a new instru-
ment, developed by the Road Research Laboratory
during investigations on surface water drainage, for
recording flow in sewers. The device records varia-
tions with time in the rate of sewage flow and the
periods of time during which the flow is in excess of
certain values selected for particular study. The in-
strument is composed of a movement recorder and
a time totalizer, the latter consisting of a time base
and multiple-contact switch-unit within the move-
ment-recorder and a separate  box containing  a
rectifier and a battery of counters.

Correlations exist between strength of radio echo
signals and rate of precipitation; confirmation is
given that differential calibration of radar installa-
tion makes it possible to measure intensity of rain-
fall irrespective of its nature during season or in dif-

TEMPORARY  FLOW   MEASUREMENT   IN
SEWERS AND DRAINS,
M. H. Diskin.
ASCE Proc, J of Hydr Div, Vol 89, No HY4, Part 1,
July 1963.

Descriptors:    'Flow  measurement,   'Sewers,
'Discharge measurement, Instrumentation.

Temporary flow measurement in circular channels,
such as sewers and drains, as well as in sewers of
other cross sections, can be carried out by  in-
troducing into the flow a pier-shaped element with
a bottom rounded to fit the circular invert of the
channel. The reduction in the area of flow causes a
critical section to develop in the throat so formed.
which gives a functional relationship between the
discharge and the critical depth at the throat and
also between the discharge and the depth at an up-
stream section adopted as a measuring section. The
device is, in effect, a critical depth flume, or a \Yn-
luri flume, with an irregularly shaped throat com-
posed of 2 openings  on either side of the element
introduced. Applying the theory of critical depth
flumes, equations arc derived relating the discharge
                                                                    1

to depth at the measuring section; the equations are
solved numerically, making use of standard tables
of properties of parts of a circle. The results of ex-
periments  performed on the proposed measuring
device indicate fairly close  agreement between the
measured and the calculated rates  of flow, most
values of the coefficient of discharge falling in the
range of 0.90 to 1.00. The experiments included
tests on 4 measuring devices, 2 in each of 2 circular
channels 10 in. and 16 in. diameter.

Warren Ellis, and C. Thorne Johnston.
Pub Works, Vol 94, June 1963.

Descriptors:  'Sewers, *Flow measurement, Man-
holes, 'Velocity, Roughness (Hydraulic), 'Instru-
mentation.

A  method  of measuring and  recording flow in
sewers is given as follows. Determine the size,
length, and slope of a sewer between 2 manholes.
For known depths  of flow in this sewer determine
velocities between the upper and lower manholes
by using dye test and stop watch. From the velocity
data determine roughness coefficient V through
the Manning formula. Prepare a depth-discharge
curve for the particular stretch of sewer. Using a
stage recorder, continuously record the depth of
flow in the  sewer for desired period, and convert
the depth data to flow  rate.  A portable, spring-
wound stage recorder is used. A special ring to hold
a bubbler tube with the tube opening at the sewer
invert is mounted  inside the sewer. Nitrogen gas
from a bottle is bubbled through the tube, and the
gas pressure required to discharge the gas beneath
the liquid is recorded as depth of flow on the
recorder chart.  The special  equipment used is
described and illustrated. Costs of equipment are
listed.

simple  weighted automatic sampler of the  type
used by  the London County Council at outfall
works is described in detail. This sampler has no
moving parts except  a pump and collects 43  sam-
ples per day totaling 4 gallons at high flows and 12

Evaluation of feasibility of using surface rain gage
data to modify radar-rainfall equation for specific
storm conditions; data used were for 19 storms, and
study was  restricted  to warm-season, unstable
precipitation and to use of 10-cm radar; normal cli-
matic network was found inadequate for modifica-
tion, for area and conditions studied, if relatively
accurate estimate is needed; however, correspon-
dence of radar and rain gage patterns was much
better with 10-cm radar than it had been with 3-cm

Article describes the use of a snap-ring tube jacked
into a sewer pipe in  which a  bubbler-tube  using
nitrogen gas transfers flow depth to a recorder.
This method requires  that a depth-discharge curve
be computed for a reach of sewer. Advantage is in
cost and elimination of problems of location and
operation of devices such as flumes.

A sewer line consisting of two 42 in. clay pipelines
running parallel in a common trench reinforced
with concrete  bedding cradles was  designed to
solve a corrosion problem in the Los Angeles area.
It replaced 7,838 feet of a reinforced concrete pipe
sewer lined with clay plates that was subject to acid
attack. The section replaced was part of a gravity
line following a steep grade. A combination of the
high-velocity  flow  and  H2SO4  concentration
caused corrosion of the concrete at a rapid rate.
Design and construction of the new clay pipeline
are briefly discussed.

J. C. Rodda.
J Inst Water Eng, Vol 21, No 2, pp 173-177, March
1967.

Descriptors: 'Rain gages, 'Standards, Rain.

Various methods for overcoming the effect of wind
on the amount of rain collected by a rain gauge are
discussed. It has been found that a rain guage  at
ground level gives the measurement approaching
closest to the real rainfall, but this is still not the
real solution to the problem. No absolute standard
for rainfall measurement is yet available, as there is
for stream flow,  and it appears to the author that
only a small amount  of progress is possible without
one. In the past a simple rule has been adopted -
that the guage giving the largest catch is the best.
The  author feels that this  cannot be sufficient
justification for a guage in the future; neither can
the use of a particular guage for 100 years be used
as an adequate reason for continuing to use it.

RADAR ESTIMATION OF RAINFALL,

J Hydrology, New Zealand, Vol 5, No 2, pp 100-
110,1966.

Descriptors: 'Instrumentation, 'Rainfall intensity.
Identifiers: 'Radar measurement. Calculations.

By calibration of equipment, power back-scattered
to radar by precipitation can be measured; power
back-scattered depends on reflectivity of precipita-
tion, which in turn depends on form of drop-size
distribution;  rainfall rate is also function of drop
size distribution, and empirical relationship exists
between reflectivity and rainfall  rate; using this
relation, measurements  of received power permit
estimate of rainfall rate; trials conducted overseas
suggest  that accuracy  of factor  of  two can be
achieved with suitable equipment on all occasions.

Descriptors: 'Rain gages, Instrumentation.
Identifiers: 'Calculations.

In gage, water flows through channel type capaci-
tor which is coupled to oscillator, thus frequency of
output voltage changes with rain  rate; calibration
curve can be expressed mathematically as sum of
two exponentials; 100 gages were fabricated and
calibrated, and statistics of these calibrations are
presented; based  upon measured data, capacitance
rain gages are found suitable for situations where
continuous rainfall rate data are desired; output of
gage is in form readily adapted for computer reduc-
tion.

 Tilting bucket rain gage was developed and manu-
 factured by Rimco, Melbourne; bucket, housed in
 standard 8 in. gage, tilts every time 0.01 in. of rain
 falls on it and tilting sends out electrical impulse
 which may operate counter located at gage or may
 be recorded on charts or tape either at gage or at
 distance; this gage bucket is gold-plated to reduce
 surface tension and to help water run more easily.

Models of four types of typical overflows: (1) a low
side weir, (2) a stilling pond, (3) a vortex with cen-
tral spill, and (4) a storage overflow with high side
weir,  were tested at two pipe  slopes, 1:500 and
1:100. The model overflows were installed in turn
at the downstream end of the pipe. The salinities of
the base flow, the spilled water and water passed to
treatment were measured by electrical conductivity
meters. Suspended and floating materials were in-
troduced  into  the pipe  by  screw-feed injector,
heavier material being put in by hand upstream.
Solids were collected by sieves. The tests were di-
vided into two categories: (a) those investigating
the discharge of dissolved pollution and (b) those
studying the behavior of bed load and suspended
and floating solids. Each structure was first tested
with saline-base flow and fresh-water storm waves
of I, 2, 3, and 4 mins.  duration. Recorder charts
were analyzed  for each structure and the duration
of each test in turn, to  obtain the discharge time
curves shown. The proportions of pollutants spilled
to the wave duration are shown by graphs as well as
the average concentrations of pollutants in the spill
as proportions  of a base flow concentration each
for  salt,  polystyrene,  bakelite,  polythene, and

In discussing the application of automatic control
devices in sewage pumping  stations, the authors
describe and give a schematic diagram of a single-
range control system in which two electrode probes
in the inflow-reception sump arc used in conjunc-
tion with a simple programme controller to control
the operation of a number of single-speed pumps of
different ratings which can be brought into service
in different  combinations. The same system can
also be used to adjust the rate of pumping in rela-
tion to the amount of storm-water overflow and to
control the rate of pumping in the recirculation of
effluent at sewage works. The  basic principles of
the system are also  applicable when other level-
sensing devices are used instead of the electrode
probes in the reception sump.

Based on  existing information on rainfall and run-
off in sewerage systems, preliminary measures are
suggested for the calculation and design of storm-
sewage overflows by determining the critical inten-
sity of rainfall at which an overflow first  occurs,
which is illustrated by nomograms. This method of
calculation is not as straightforward as the existing
dilution process but it has the advantage that pre-
dictions can be  made on  both the frequency of
operation and the duration of the overflow.  It  is
these criteria which determine the state of pollu-
tion in the receiving water and permit a uniform
and even treatment of the storm-sewage overflow
in a cross section of the channel. This confirms the
usefulness of this method, since heavy rainfall in
sewerage systems can be retained, thus reducing
the polluting load on the receiving water.

which is then pumped to a tip at the edge of the
works. A weir overflows storm water in excess of
85 million  gal/d direct  to  the River Soar; the

to permit gravitation through the works. Two of
these pumps, each of which has a capacity of 7,500

The  equipment claimed for dealing with storm-

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
direct to the foul 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 foul sewer.

design of overflows to reduce pollution (by provid-
ing storage for the first flush of storm sewage and
minimizing the amount of  floating and heavy-solid
polluting material in the overflowing sewage), and
the treatment of storm sewage at the sewage works.
It is  recommended that each sewerage authority

Small self-priming siphons have  advantages over
weirs for storm  water overflows  and other water
level regulating uses in sewers and canals. They arc
as a rule cheaper than weirs  provided that at least
one foot of head is available. The siphon is more
flexible  in operation than a  weir. Siphons cnn be
made very sensitive, and by admitting air in limited
quantities, their discharge  can  be  varied con-
siderably. Also installations of a battery of several
siphons  permits  flexibility of discharge. Nine illus-
trations  of siphon designs are given. Self-priming of
a siphon is achieved by allowing a sheet of water to
flow over the whole width of the crest so that as the
sheet falls it strikes the opposite wall of the siphon.
The falling sheet of water entrains air with it and
carries it down to the outlet so that the siphon very
quickly  primes.  A  formula for estimating the
discharge of circular siphons flowing full is given.

conducted  on a hydraulic  model, which  is illus-

 The total capacity of a stilling pond may be suffi-
 cient to prevent discharge in storms of short dura-
 tion and moreover, the solids dislodged from the
 sewer in the early part of the storm flow may be
 retained and passed into the sewer when flow sub-
 sides. The behavior of gross solids was investigated
 to determine how the pond may be proportioned to
 minimize the quantity  of solids in  the discharge.
 The essential features of the type of stilling pond
 under consideration are illustrated, as well as the
 form and action of the air-regulated siphon and the
 water circuit. The experiments were arranged first
 to establish a valid technique on a pond of specified
 geometry, and then to use this technique  to ex-
 amine and develop geometrical shapes which ap-
 peared to offer the possibility of high efficiency.
 Tests were made to compare the performance of a
 rectangular stilling pond with that of a side weir
 and that of a fan-shaped chamber with an end weir.
 The rectangular design is shown to be superior in
 its handling of gross solids. From the tests and with
 VC (1/2)D/U as a parameter, recommendations
 are given for design dimensions of:  (a) pond size,
 (b) siphon type and position, (c) scum board size,
 and (d) invert shape. The efficiency of a pond thus
 designed may be obtained from given curves.

Results are given of investigations at Northampton,
Brighouse, and Bradford on the frequency and du-
ration of operation of storm-sewage overflows on
combined sewerage systems and on the volume of
storm sewage discharged, since this knowledge is
required when determining the optimal setting  for
an overflow. From the results, equations have been
developed which were found to fit not only the data
from these three systems but also those from a par-
tially-separate system at Luton; some examples are
given of the use of the equations to determine the
setting so that the overflow would operate only on a
certain number of occasions per year or that the
average yearly discharge should be a certain per-
centage of the rainfall.

Considerable pollution of surface  waters is caused
by sewage discharged from storm  water overflows.
Author considers that in many cases improvement
could be effected by reducing the  number or alter-
ing the position of overflows and in some instances
larger volumes could be treated at  the  sewage

At the Earlswood sewage works of Reigate, Surrey,
storm water was formerly separated by means of a

The reasons for this decision are listed, and details
of the installation are described.

The stilling pond overflow pipe, which provides the
most efficient means for the separation of 6 times
the dry weather flow from storm water flows, and
for removing suspended solids from storm water, is
described, and  the one in use at  Mixenden  is
presented diagrammatically. Tests carried out at
Halifax on this type of overflow and its calibration
are given in detail, and show the variation between
discharges allowed for in design and those met with
in practice. Equations are  derived for the deter-
mination of several factors including the hydraulic
gradient, velocity head, and friction loss. From the
studies so far carried out, it was concluded that the
stilling pond is the best type of storm overflow at
present in general use.

The use of stilling ponds is considered to be the
most effective way  of reducing  pollution from
storm-water overflows, since an efficient stilling
pond should  retain  much of the  solid matter
discharged during the first flush of storm water and
subsequently pass it down the sewer as the level
falls. The authors have carried out preliminary tests
on a model stilling pond equipped with a siphon in
place of the usual overflow weir; the results, which
are discussed briefly, warrant more detailed in-
vestigations, using suspended particles of various
sizes over a  continuously graded  spectrum of
specific  gravity, to establish optimal proportions
for stilling ponds with siphon overflows.

After  presenting the weak points of the notion
'dilution' in hydraulic measurement of stationary
rain overflows, the author recommends the specific
content (related to the unit of water amount) of
one or more components (specific load) as the
criteria for the admissible load of the receiving
stream. The developed formulas permit: the calcu-
lation of the expected upper limit value of the
specific load and the calculation of the overflows;
the numerical expression of the conditions in case
of more overflows  from the same collector; and
exact information about the effects of sludge  whirl-
up in the collector or about the imperfect mixing of
the individual incoming and outcoming amounts.
The influence on the load can be expressed by the
(temporary or continuous) magnitude change in
one of the load determining factors.

Rainwater overflows with high weirs and throttled
outlet systems have recently been used to limit the
load of receiving streams. The infeed system lying
above the weir limits the duration and frequency of
the overflow. The  efficiency of the throttle line is
determined by the diameter, the length, and the
slope of the bottom of the line. Because of high
costs it is not advisable to undertake any recon-
struction of the throttling line or to construct it be-
hind already existing non-throttled rainwater over-
flows. The same holds true for repairs of errors
caused by incorrect calculations. In such cases, use
is  made of the throttle stop. Located above the
canal network outlet, the stop closes the flow in the
upper infeed section of the network. A  method is
described to calculate one-sided rainwater over-
flows with throttle stops. This method can be ap-
plied in almost all cases in which, in the infeed por-
tion, a normal streaming run-off (t sub N> t sub gr)
is observed or in which, in the case of a shooting
normal run-off (t  sub N< t sub gr), a  streaming
run-off above the weir can be forced (S sub N< S
sub o). The parameters required for the calcula-
tions were obtained on models with circular pipes.
However, they can be applied for other  cross sec-
tions as well, provided the same conditions arc ob-
served.

water runoff equal in volume to the dry weather
flow of domestic sewage was produced when rain-
fall was 0.01 in/hr. When twice the average dry
weather flow was intercepted about 2.7% of the
total amount of domestic sewage overflowed. Over-
flow occurred  about  5-6  times/month  in the
summer. The effects of increasing the capacity of
the interceptors  on the amount of sewage in the

A unique plug valve designed to permit automatic
bypass of an 84 in. trunk sewer has been installed
by the Bergen County Sewer Authority in New Jer-
sey. An overflow chamber was constructed over
the 84 in. line just before the sewer crosses the
Hackensack River. The valve  consists of a large cir-
cular  plate with a continuous circular ncoprene
gasket riveted to the underside to prevent infiltra-
tion of water due to tidal conditions and also to seal
against odors when not operating. The cylinder,
mounted on the underside of the plate, acts as a
buoyant force and the lift is counteracted by the
addition of lead ballast into the cylinder. The valve
is designed to lift when the gradient of the sewer is
2 in. above the  top of the overflow chamber. Side
guides set around the cylinder keep the valve cen-
tered. Valve stops are mounted above the overflow
chamber to prevent the valve from being lifted out
of the opening. The complete  valve, weighing
about  4,000  Ib, can  be  lifted for inspection by
means of jacks.

 The policy adopted by  the city of Rochdale to ac-
 cept all liquid trade wastes made it necessary to re-
 calculate the loads on the entire system. This recal-
 culation led to the decision to reconstruct some of
 the original storm sewage overflows to accept the
 additional  loads. Since a large number were in-
 volved it was decided to reconstruct one overflow
 on an  experimental basis first. Part of the experi-
 ment was to determine the conditions when a storm
 occurred which only just put the overflow into
 operation. The effect of surcharging the sewer be-
 fore allowing the overflow to begin was that nearly
 all floating matter was held back some distance up-
 stream.  Matters of public  relations undertaken
 when an overflow in a shopping area  was recon-
 structed are given in detail. Although the work on
 overflows has formed part of a comprehensive pro-
 gram, the reconstruction of each had its particular
 problems.  Ultimate design was dependent on  a
 number of existing factors, some fixed and some
 varying with limits.  As  work progressed, it was ob-
 served that: (a) a far greater volume of sewage was
 being  passed to the sewage  works; and (b) the
 discharge of floating matter to the water courses
 during storms was decreasing.

 The extent that the ideals of theory can be realized
 in the practical design of storm sewage overflows is
discussed with special emphasis on efficiency and
reliability. Two tests of efficiency for storm water
overflows are: (a) hydraulic performance, and (b)
separation of suspended solids. Hydraulic efficien-
cy implies that overflow does not commence pre-
maturely and that the base flow does not vary with
the rate of overflow. The two possible approaches
to efficiency in separation of solids are to use physi-
cal  methods of  restraint  or to  rely on  gravity
separation. The relative merits of screening, stilling
ponds or vortex action in separation are discussed.
Reliability is taken  to include  safety and con-
venience in  operation as well as the more direct
meaning. The structure should be designed for a
life in excess of 30 years. Power driven devices are
best avoided unless  adequate and regular main-
tenance is assured. Emergency by-pass arrange-
ments should be made. A design of 1937  is illus-
trated and discussed as well as  a high weir type
overflow.  More opportunity is afforded in desig-
ning large overflows on new sections of sewer; one
such design  is shown. No overflow  should  be
located on sewers less than 18 in. dia. or of max-
imum flow less than 6 cusecs. For small overflows
the storage type are suitable; with larger flows only
limited storage is likely to be practicable.

 A model was used to study the possibility of using
 the helical flow in short bends as a basis for the
 design of storm sewage overflows. Fora short bend
 a convenient measure of the intensity of the helix is
 the angle  between the circumferential  direction
 and the direction of flow very near to the bed of the
 channel. Several expressions were developed  to
 predict the value of this angle. There is evidence
 that in a bend longer than 0=90 the intensity of the
 helix  decreases, and that eventually at 0=180 the
 direction of water near the bed reverses toward the
 outer wall. If a relatively short bend is followed by a
 second of opposite direction, the helix generated in
 the former suppresses development of the helix in
 the latter. However, an  S  channel may be more
 convenient to use and was therefore  investigated.
 The symmetrical S shape of the channel was chosen
 so that a number of possible configurations of the
 relative positions of slots and overflows could be in-
 vestigated by reversing the channel. Figures are in-
 cluded to show the bed load distribution both with
 slots closed and opened; the relationship between
 suspended load and flow through the  slot; and the
 relationship between bed angle in the first bend and
 Reynolds' number in a semicircular channel. It is
 concluded that the results of the investigation may
 be used to design an  effective and  cheap storm
 sewage overflow.

In designing storm-water  overflows, the  use of

permits comparatively  accurate regulation of the
flow but also results in less polluting matter being
discharged. Model experiments were carried out on

to determining the conditions  limiting chamber
design and to deriving suitable design standards.

tion time, with crude macerated sewage having a
mean strength of 230 p.p.m. suspended solids, are
shown. It was found that a very significant degree
of separation took place.  To achieve  satisfactory
conditions of flow many alterations in shape had to
be made, in particular a deflecting wall alongside
the in-coming sewer. Floating solids were easy  to
retain by dip-plate. The number of occasions on
which the overflow operates per year and the dura-
tion of such occasions would give a better criterion
for design than any estimate of what should be left
in the sewer. A method of design based on statisti-
cal analysis of rainfall is given, which enables the
designer to choose the size of overflow best suited
for any particular site.

A prime objective of the virtual resewerage of an
area of about 27,900 acres at Coventry is the
elimination of pollution in the river system, which
forms the headwaters of the River Avon. The solu-
tion lies in the building of Storm Balancing Sta-
tions. In time of rain all flows in excess of 3 d.w.f.
are spilled off into mechanically scraped circular
tanks. Sludge is evacuated to the sewer. The provi-
sion of additional tanks or other processes is feasi-
ble. The tanks are probably unique in that overflow
to the tanks, operation of the scraping mechanism,
continuous pumping of sludge, sampling, tank emp-
tying to the sewer and rising main emptying are all
automatic. Results are beginning to become availa-
ble from one station. Conclusions are that if in the
future a proportion of the flow in a foul sewer may
be discharged directly to the river the device for
separating the elements must be designed on a
more scientific basis, and the solution may lie in the
provision of storm balancing tanks.

Further details are given of theoretical and experi-

and storm drains, which have been carried out by
the Hydraulics Research Station (see Wat. Pollut.
Abstr., 1963, 36, Abstr. No. 1823) including ex-
periments on salt-glazed, spun concrete and pitch-
fibre pipes, both full and partly-full. The results,
given in tables and graphs, show that flow condi-
tions in new sewers are turbulent-transitional and
that the eccentricity and spacing of the joints affect
the overall roughness. Neither the Crimp and
Bruges nor the Manning formulae fit  the experi-
mental  data   and  the  equation  proposed  by
Colebrook, C.F., and White, C.M., is preferred. On
the basis of data obtained, roughness values for
new sewers are suggested. Under partly-full condi-
tions, proportional velocities follow the theoretical
trend,  but  are lower, indicating an increase  in
roughness for free-surface flow, the possible cause
of which is discussed.

When the sewage flow is so divided that half con-
tinues in the same direction, half through a pipe at
an  angle, then  about  97% of the sludge  goes
through the  latter  pipe when the  angle with the
original direction is 30 degrees, about 87% when it
is  120 degrees. These data are  significant in the
construction of plant  by-passes to provide for
heavy flow resulting from rains so that the richer
sewage  goes through the  plant,  the dil. being by-
passed to the river.

 The  object  of design of outfall  sewers was to
 destroy  the  physical character of the  sewage
 without  objectionable odors,  floating solids at
 shore line, scum accumulations or bottom deposits.
 Present day standards require, in addition, a reduc-
 tion of bacterial concentration. In discussing design
 the author states that shore overflows  from plant
 should be avoided and provisions should be  made
 for emergency chlorination. In New York City ex-
 perience has shown that  0.02  in/hr  rainfall has
 resulted  in discharge of approximately 30% raw
 sewage from combined sewer overflows. Also that
 from  70 years of records, one to two rainstorms of
 over  0.02 inch/hour occur each week  during the
 summer. The receiving waters remain polluted for
 a period of one to three days after each rainfall.
 Author discusses  location of outfalls, hydraulic
 considerations,  and design of outlet structures. In
 design the author uses the charts and formulas of
 Rown and Palmer and shows the theoretical com-
 putations of mixing of sewage with sea water. Each
area must have tests taken to assess the effective-
ness of mixing. The author discusses construction
and maintenance of outfall sewers and also costs of
same.

Methods were developed for obtaining  data  on
velocity and discharge in sewers for use in calculat-
ing the coefficients in hydraulic equation, and these
techniques were used on 95 small sewers. The data
obtained,  together with published studies on ex-
perimental pipes,  confirm the conditions of previ-
ous investigators  that  velocities  in  partly-filled
pipes do not conform to the traditional equations.
From the data obtained, equations were developed
for velocities in partly-filled pipes of circular sec-
tion. The  experimental results also confirmed the
accepted view that a velocity of 0.5-0.6 m per sec,
or 1.6-2 ft per sec, is required to avoid excessive ac-
cumulations of debris. There was evidence of a  re-
tarding effect of critical-depth turbulence, but it is
impracticable to avoid these effects in the smallest
sewers. It was found  that poor construction, includ-
ing irregularities of slope, is often the cause of poor
coefficients;  the  asbestos-cement sewers  tested
showed better coefficients than the  vitrified-clay
sewers, and the concrete sewers were poorest.

Field 03—SEWER HYDRAULICS
It is important, for a variety of purposes in the sani-
tary  engineering field,  to  be  able  to  calculate
velocity and flow conditions in sewers running less
than full. The equation which has  come  to  be
known as Manning's is  most commonly used for
this purpose. This equation rests upon the classical
assumption  that  velocity can be calculated as a
function of R, S, and a friction coefficient. This
basic assumption is an approximation when streams
of different shape of cross section are considered.
This following equation has been deduced for cal-
culating velocity of flow in a partly filled pipe of
circular cross section. V= k (Q exp. 0.29) (S exp.
0.38) (D exp. -0.13). This equation conforms to
available data better than the Manning  equation.
The value of  k is related to the Hazen-Williams
coefficient by the equation k= 0.702 m C (0.71) in
which m is approximately 1.10.

The  author discusses the possibility  of inserting
storm water tanks in sewerage systems. Where the
depth of the tank is somewhat less than the internal
diameter of the inlet channel, no gradient is neces-
sary. The use of such inserted tanks to reduce the
load  on  pumping plant  and sewage  works  is
discussed with examples of their effect in  various

In connection with a master plan for trunk sewers
and  sewage-treatment  facilities  in Kansas City,
Mo., a series of velocity measurements was made in
a large trunk sewer carrying both sewage and storm
water. The method used to measure mean velocity
is described; it is considered to be as simple, accu-
rate,  and  inexpensive  as  more conventional
procedures. Variations in n in Manning's formula
occur with changes in depth of flow in sewers and
for certain sewer designs such variations can be im-
portant. The value of n can be changed from that
used in the design of the sewer by a number of con-
ditions brought about during construction or which
can  occur afterwards.  Bottom deposits  or other
conditions which greatly alter the invert surfaces of
the sewer probably caused a greater variation in n
than that caused by changes in depth of flow. Some
aspects  on  which  further  investigations  are
required, are indicated.

After a  brief review  of the general properties of

sewers of adequate carrying capacity. The concept
of optimal sewer diameter is developed, and the
relevance of criteria  of self-scouring and  carrying
capacity is considered.  A design chart is given for
the solution of problems of a general nature, with
some practical examples of its use.

separate storm and sanitary sewer discharges in the
United States. A pilot project to construct  two
giant rubberized tanks in the Anacostia River in
Washington, D.  C. to store overflow during heavy
rainfall is also mentioned. Each tank has a capacity
of 100,000 gallons and will be anchored in the river
bed. During the  period of overflow, sewage will be
diverted into an  on-shore  pump house where it will
be crushed before  being pumped into the tanks.
The contents of the tanks will be pumped back into
the sewer lines after the storm water recedes.

was for studies of improved methods for dealing
with overflows from combined sewers. Nine cities
were awarded a total of slightly more than $8 mil-
lion to help finance such projects as construction of
large  detention basins  to hold combined sewer
overflow prior to treatment, and for installation of
automated  sewer  regulator  stations designed  to
provide better control  of combined flows. Con-

to a new main interceptor tunnel. The inner sewer
slopes in the  opposite direction from  the outer
sewer, which is accomplished by starting the high
end of the inner sewer at the top of the large sewer
and spiraling it down the outer sewer wall.  In one
 location because of corrosive  wastes the inner
sewer consists of 1440 ft. of 15 in. dia. PVC plastic
pipe. In the other location the inner sewer is 1303
ft. of 12 in. CI pipe. The 15 in. sewer cost $20.41 to
 $24.41  per ft in place. The sewer within a sewer
 technique  permitted main interceptor  modifica-

in peak to average DWF found because of size of
community. Agreement with other investigators
that from 0.03 to 0.04  in./hr is needed to wet down
area before run-off. Each 0.01 in./hr will produce
run-off equal to DWF. In Kansas City it was found
that measurable rainfall occurred about 5 per cent
of the time. Of this 3.7 per cent of the time run-off
could occur. With a peak dwf of 1.5 x ave. dwf and
a interceptor  capacity of 1.5 x ave DWF it was
found overflow would  occur 3.72  percent time— to
peak dwf.  If interceptor was increased to 3.5 ave
dwf, overflow would still occur 3.22 per cent of
time and 6.5  x ave  dwf 2.3  per cent of time.
Authors conclude that the practical maximum ef-
fective capacity of interceptor can  not be much
larger than the peak dwf. Also recommend more
work be done  in characteristics of storm water ru-
noff.

 cited above. Accordingly, the author proposes that
 it is necessary to come to some agreement as to the
 coefficient of probability to be used for economical
 sewer design, and that it should not be necessary to
 depend wholly upon the judgment of the designer.
 Of course, the establishment of suitable norms
 must be based upon thorough and complete calcu-
 lations and review of existing data. No one, accord-
 ing to the author, has dependable results, as practi-
 cally none of the designers have had the opportuni-

 because in many cases the system has not  been
 completed  as designed, the drainage area has not
 been fully settled, or the rains designed for have not

 Subject matter discussed in this paper on intercep-
 tor sewers applies specifically to the design of the
 interceptor sewers of the  Metropolitan St. Louis
 Sewer District Pollution Abatement Project. The
 paper includes as background information, a brief
 description of  the  District,  as well as  a brief
 description of the overall plan of the proposed in-
 terception, pumping and treatment facilities. The
 methods used in gaging present  flows are  also
 discussed and a number of measured sewer hydro-
 graphs are reproduced. Detailed investigation of
 the spill of mixed sewage and rainfall with intercep-
 tors of several different capacities is discussed in
 considerable  detail  leading  to the finding  that
 adequate abatement of pollution can be achieved
 with interceptors having a capacity equal to the
 peak rate of sewage flow.  In this investigation
 sewage flow was considered to consist of domestic
 and industrial waste flow only; it did not  include
 ground water infiltration.  However, to completely
 avoid spill during dry weather, it was further con-
 cluded that  interceptors, in  final  design, should
 have a capacity equal to the peak flow of sanitary
 sewage plus the peak rate of ground water  infiltra-
 tion. Detailed computations of sewage spill were
 made under conditions of present and assumed ulti-
 mate watershed development for interceptors on
 two of the largest sewers of the District as finally
 designed. Two typical  interceptor structures are
 discussed and  illustrated. Storm water flows for
 several assumed runoff rates and the effects of such
 flows on the  hydraulics of the trunk interceptor
 sewer are discussed. Finally,  in order to illustrate
 the disproportionate effect on cost when compared
 to the small improvement in pollution abatement
 accomplished by increasing interceptor capacities.
 The trunk sewer was resized to accommodate 1.25
 times peak dry weather flow. A cost estimate of the
trunk to  carry the  larger flow was prepared  and
compared with the estimated cost of the trunk as
designed. The reduction  in  degree  of pollution
abatement which would have been achieved by the
slightly larger interceptor was also computed and
shown to be inconsequential. The economic inad-
 visability of increasing interceptor capacity  beyond
one times peak dry weather flow for the St. Louis
sewer system was demonstrated.

 several days after discharge has ceased, with dura-
 tion of effects increasing with increase in the inten-
 sity of the storm. Bacterial densities may increase a
 thousandfold after  moderate  rains at  sampling
 points, within several miles downstream from com-

 creases in bacterial densities are less, but occur
 over greater portions of the stream width.  Fecal

Sewers originally were constructed to drain cellars
and land, and later were permitted to carry sanitary
wastes. Many older cities in the United States have
the combined type of sewer system and now face
the need for separate systems for sanitary waste-
water and stormwater. The costs are estimated to
be  $10,000-$20,000/acre ($25,000-$50,000/ha),
not including the cost of possible repairs to storm
sewers. Although only three percent of the annual
wastewater production is discharged  by combined
sewer overflows, greater amounts of bacteria and
suspended solids are dislodged by high flows after
storms. Other methods proposed to alleviate over-
flow effects are not so effective as separation.

 The author discusses the possibility of reducina
 pollution caused by discharge of storm water from
 combined sewers. It would  not be economical  to
 build sewers large enough to carry the max. flow to
 be expected, for example once each year, but storm
 overflows which discharge to a  stream  when the
 flow exceeds 6 x dry-weather flow cause considera-
 ble pollution. Storm tanks are a  more satisfactory
 method of dealing with storm water, as sedimenta-
 tion can take  place and the effluent when the tank
 overflows is of a less polluting  nature. It is  sue.
 gested that an existing combined sewerage system
 could  be  expanded by  constructing large storm
 water balancing tanks at various points on the main
 intercepting sewer. Storm water could be stored in
 these tanks and discharged to the sewers as capaci-
 ty  is available.  A  method for calculating the
 required  capacity of the storm  water balancing
 tanks is shown in a table. In discussion, Bevan,  t
 V., Ackers, G. L., and Towscnd, G.  B., all stated
 that the chief difficulty with the system proposed
 would  be the removal of the sludge  which would
 accumulate in the balancing tanks and  might give
 rise to septic conditions.

The author states that storm overflow weirs are an

eliminated wherever possible. Overflow from storm
tanks is much to be preferred to storm sewer over
flows as the overflow from the tanks has been rid of
virtually all  scttlcable suspended matter. Author
derives a procedure utilizing storm balancing tanks
which take excess storm water from upper laterals
and later return  the flow by pumping.  Thus the
peaks are removed and all storm water ultimately

The author presents both the valid and 'fallacious'
arguments for the preference of separate over com-
bined sewerage systems. He repudiates the most
commonly given reasons for not using combined
system; that is, that the large size pipes necessary
for the storm flow will be silted during dry weather
flow and if the gradient is increased to bring the dry
weather flow to self-cleansing standards, excessive
depth will result. He points out 'that, while increase
of diameter above that required  for the flow does
usually reduce velocity, this reduction is very small
indeed, so that in the majority of instances a com-
bined  sewer  has   a  satisfactory self-cleansing
gradient if it is laid to the same gradient as would be
adopted for the soil sewer if the system were to be
made separate.' An  example is given.

 Most of the larger and older cities in the U. S. A.
 are served by combined sewerage systems resulting
 in pollution of waterways through overflows during
 storms. Such  pollution  could  be  removed  by
 complete separation of storm water and sanitary
 sewage by the construction of a new system of sani-
 tary sewers, but this would be expensive and incon-
 venient and is therefore of limited application. The
 interception and treatment of the dry weather flow
 and the first flushings of storm water will reduce
 the  volume of sewage discharged through  over-
 flows to about 3 per cent of the total sewage flow,
 and with  complete treatment of the intercepted
 flow about 90 per cent of the BOD can be removed.
 Treatment of intermittent discharges from  over-
 flows  by  retention and  Chlorination to  remove
 floating solids and bacterial contamination can also
 improve conditions in receiving streams at reasona-
 ble cost.

The combined system of sewerage while having
many advantages is at times criticized because of
excessive cost on account of the  large pipe sizes
required to accomodate the maximum run-off from
severe storms which are of short duration. Lack of
attention to this condition results in flooded cellars.
These objections may be overcome to a large ex-
tent by designing the inlets for a limited capacity
which the sewer can accomodate and utilizing the
storage capacity of the  streets to hold the surplus
runoff. The streets are thus temporarily flooded to
a  depth  of an  inch  or two.  When the rate of
precipitation slackens  the stored water quickly
drains off through the inlets. This limitation of rain
water inlets unites both the simplicity and efficien-
cy  of the combined  system and  two of the  ad-
vantages of the separate system, namely freedom
from risk of cellar flooding and reduced construc-
tion cost. Data are presented for the town of Fal-
kenburg for which such a system was designed, tak-
ing into account the various  street grades and
resultant gutter capacities. The methods  of com-
puting rates of run-off, inlet sizes, etc. are given in

method was also in use in India and Panama.

system. Taking into account the requirements for
sewage treatment and  prevention of pollution of
streams, detailed information is given on how risks
of pollution by storm-sewage  overflows and rain-
water pumps can  be avoided. Taking into con-
sideration  the availability  of existing  sewerage
systems, receiving waters, and local conditions, the
author suggests that it must be decided individually
whether the  separate or the combined  system is
preferable. Where a new sewerage system is to be
installed and good ground-water conditions prevail,
the  combined system  was found to  be  more
economical and adaptable; however, where  the
velocity of flow is low and a higher water level is
required,  the  separate  system is preferable espe-
cially when mineral substances can be washed away
by the storm-sewage system.

Any properly designed and constructed combined
sewer,  without making use  of the  storm water
storage, will produce results in the range of 98 per
cent efficiency and any expenditure of public fund!
to improve its operation should not be made lima
necessity can be clearly shown. The adoption of the
plan  of designing storm water storage into conk
bined systems to the extent possible or desirable
will increase the efficiency of any combined system
correspondingly. Generally speaking,  the designing
of storm water storage into a combined system in.
creases the cost very little. Adding this feature to
an existing system would cost more but would still
not be a major expenditure. Separate systems will
discharge to the receiving waters with every storm
exceeding 0.03 in/hr or about 89 times each year
for the area studied, and the quality  of the storm.

Chicago (III).

A study was made of flow rates and composition of
overflows from a large combined sewer serving a
residential area of 8.6 square miles with a popula-
tion of 144,300. Overflows occurred during 1.7 per
cent of the time, in a 14-month period when rainfall
was about 75 percent of normal. Gross bacterial
pollution was discharged during overflows, limiting
the use of the receiving waters from a public health
standpoint. Suspended solids concentration in the
overflow was greater on the average than that of
dry weather  flow, with considerable variation as-
sociated with rainfall intensity and time since the
last storm. The  5-day BOD concentration in the
overflow averaged about  one-half  that  of  dry
weather flow, and was found to decrease with time
after  overflow  started.  The  total  BOD  load
discharged during overflows was 2.5 times the dry
weather BOD load for the same number of hours.
By  extension of the observed data, it is estimated
that the  BOD load resulting from combined sewer
overflows accounts for about 19 per  cent of the
total BOD load in the canal system  serving the
Chicago area.

each case a value  can be determined for the rainfall
limit at which the overflow comes into action. He
shows how the overflow and the dilution can be re-

Chicago plans to use a tunneling mole to construct

which all of its combined sewers would discharge.
The cost of building the tunnel, referred to as the
'underflow  mainstream', using this method is  $2
million less than that for the conventional open-cut
method of construction. The underflow system was
simulated by a computer study, the results of which
are tabulated. It is felt that the underflow sewer will
demonstrate  the  feasibility   of  constructing
economically a detention resevoir to greatly reduce
the river pollution cuased by overflows from com-
bined sewers, far below the surface in public right
of way, while providing the conveyance capacity to
reduce basement and underpass flooding. It should
also demonstrate the practicability of constructing
an enlarged underflow mainstream system to serve
the entire City of Chicago and  the surrounding

systems. Calculation  of the permissible amount
must be based on the  annual amount of discharge
and of  polluting matter in it, the self-purifying
capacity of the stream, and the use made of the
stream water.  Investigations are required into the
condition of the storm water in modern conditions

For the Buffalo New York area, author has derived
a characteristic factor for a district 'Ch' which is a
ratio of average dry weather flow (gpd) to the ru-
noff (cfs) during a uniform rainfall of  1  inch/hr
(Ch= d over c). Study of sewage quality or strength
during a 0.55 inch/rain indicates flow doubled,
suspended solids 4-5 times, BOD in ppm decreased
about  1/3, but total load was higher. During the
rain the flow was 5 times and the suspended solids
rose to 1220 ppm over an average dry weather con-
centration of 186 ppm. Author stresses point that
the biggest  contributor to  the suspended solids  is
the material deposited in  the sewers themselves
during dwf. Recommends that  sewers  be  con-
structed to  be self-cleansing and also favors small
storm  water tanks  be  located on laterals and

flows from industrial sources. Subsequent annexa-
tion led to the acquisition of 3 more works; one of
the original plants has been  closed down and the
others have been expanded and modernized. In ad-
dition, an industrial waste control programme has

sewer to carry the sewage to the treatment plant
were studied, and  it was decided  to install the
flooded-tunnel type, in which the sewage is allowed
to rise in the wet well of the pumping station at the
treatment plant to such a level that the upstream
hydraulic gradient allows all diversion structures to

balanced against the purifying power of the stream
as indicated  by the flow,  deoxygenation,  and
reaeration consts., BOD, and dissolved oxygen con-

through which dry-weather flow passes direct to
the interceptor sewer after screening; but when
flow in the sewer reaches a maximal level, passage
through the detritus tanks is stopped, and the reten-

sufficient to fill the tank, the chlorinated sewage is
discharged to the  harbour.

to equalize the flow to the plant throughout the
day, and this is achieved  by  utilizing the storage
capacity of the sewers and by selecting a suitable

Engineers of sewage treatment facilities in six areas
of the U.S. were surveyed concerning sewer infil-
tration: frequency of determination of the extent of
infiltration, percentage of sewer flow resulting from
infiltration, steps to reduce infiltration, and effect
of infiltration on the treatment plant operation. In-
filtration was reported to be  a problem in each
area. Steps used to curb  infiltration were: prompt
repair of broken or damaged sewers, replacement
of sewer pipe with pipes of materials better suited
for the  area,  and enforcement  of ordinances
prohibiting footing drains and downspouts. High
cost prevented the use of sewer linings and chemi-
cally-sealed joints. Root infestation  was also a
problem in each area surveyed. It is the most dif-
ficult  source of infiltration to locate and correct
and may account for as much as 50% of total infil-
tration. Infiltration affected treatment plant opera-
tion by increasing the cost of pumping and reduc-
ing BOD and suspended  solids. Percentage of the
total flow in the sewers resulting from infiltration
was estimated to vary between 10 and 50%.

Experience in Kentucky  has already proven that it
would have been much easier for the cities to have
acted firmly on the matter of overloading of sanita-
ry sewers by residence drainage than to suffer the
consequences of leaving private sewers to  builders'
and owners' methods. Quality control of private
sewer construction and  regulation of the use of
sewers are imperative to a totally successful sanita-
ry sewer system.

New chemical grouting method  tried in Sudbury,
Ont., to repair gaps between joints in sewer system
and prevent infiltration consists of TV camera and
rejointer apparatus  attached   to  cable  drawn
through sewer lines, when leak joint is noticed,
rejointer is drawn to edge of pipe joint, then drawn
required distance to have it centered at joint which
is then confined and calked by remote  control
using chemical grouting material; rejointer consists
of hollow aluminum cylinder slightly  smaller in
diameter than pipe, encased in rubber jacket which
is strapped to cylinder at ends and at center.

City engineers in Muskegon, Mich, designed sanita-

rubber O-ring joint gaskets, and good construction
and inspection procedures; tests on completed line
show infiltration to between  14.5 and  55.7% of
maximum allowable rate of 200 gal/in, of internal
diameter per mile of pipe per day; much of this in-
filtration  took  place at precast manhole joints,
which did not have rubber O-ring joint specified.

A  study  of sewer  systems  in four communities
revealed that flow of domestic wastewater follows
indoor water use and  undergoes little seasonal
change. Per-capita use increases with the economic
status of the area. Flows of stormwater and ground-
water infiltration often exceed domestic flows con-
siderably where poor sewer construction and illicit
connection to the system are prevalent. Stoppages
are caused  chiefly by  roots and accumulated
deposits, the latter especially at the upper ends of
systems. Bitumastic joints are most resistant to root
penetration; newer materials have not been evalu-
ated. Other causes of stoppages are slug discharges
of grease and mud from construction.

The author summarizes events which led to the ap-
plication of Terraseal for controlling infiltration of
ground  water into sewers in the rural district of
Amersham, Bucks. As a result of infiltration the
cost of disposing of sewage, which is discharged to
the West Herts Main Drainage Authority, became
disproportionate to  the population served.  A
method of assessing flow, used in river gauging, was
used to determine  volume of infiltration between
sampling points. Initial measures to control infiltra-
tion were unsatisfactory, but a new chemical grout-
ing process using Terraseal  has resulted in a high
degree of success. Terraseal  is a form of sodium al-
ginate capable of forming viscous solutions and of
being converted to a stable jelly; addition of a suita-
ble inhibitor to the solution during preparation
prevents micro-organisms from attacking the jelly.
The method of application is described.

Identifiers: 'Sewer infiltration.

A procedure for repairing leaks in sewer lines,
known as telegrout, involving the use of remote
control grouting, is described. Equipment required
in the process includes a van-type truck, chemical
grout mixing and pumping equipment, sewer grout-
ing packers and plugs, air compressor, television in-
spection components, winches, downhole sheaves,
and  communication  system. A winch  cable, to
which is  attached a television camera and sewer
grouting packer, is pulled through the sewer line.
The trailing winch line is attached to the grouting
packer,  and  a  communication  line  is placed
between  the  two winches and the  grouting en-
gineer. The  inline equipment  is  then moved
through the sewer line. When a leak  is observed on
the television monitor, the grouting packer is set
over the leak and  sufficient chemical  grout  is
pumped through the set packer to  seal the leak.
The  grout requires  5 to  15  minutes to  set.  The
television inspection system may also be used for
survey work to determine the condition of lines be-
fore  starting a  repair program. Pictures can be
made from  the  monitor screen for permanent
records of lines being surveyed or repaired.

The article describes the layout and construction of
the early sewers in Tonawanda, N.Y. Improper
planning, poor construction, lack of storm sewers,
and the diversion of surface water into the sanitary
sewers caused flooding of the sanitary sewers dur-
ing periods  of  precipitation.  Increased  tributary
population intensified  sewer problems. Several at-
tempts were made to remedy the situation. In 1945
a comprehensive storm drain plan was developed
to eliminate the excess water from  the  sanitary
sewers. The types of storm sewers used, design
criteria,  construction  details, and costs  are  out-

Low-pressure air test for sewer leakage has proved
reliable, easy  to use, and inexpensive;  test, for
which specifications have been developed, consists
of introducing air into plugged section of pipe and
measuring time needed  for pressure to be reduced
from 3.5 to 2.5 psi (0.24 to 0.18 kg/sq cm); nomo-
graph is used to compute time acceptable accord-
ing to specifications; increased wetness of pipe wall
reduces air leakage through pipe-wall permeability,
whereas increased  pressure gradient between in-
side and outside of sewer increases leakage.

Testing a sewer pipe for leakage by the use of air at
pressures of approximately 3 psi can measure effec-
tively the quality of the installation. New work can
be tested by noting the time required for pressure
in a closed section of the pipe to drop from 3.5 psi
to 2.5 psi. Where significant leakage is present, it
can be quantitatively determined by metering the
amount of air required to maintain a pressure in the
test section. The effect of moisture on the permea-
bility of vitrified clay pipe and its effect on the test-
ing procedure is determined.  Specifications  for
testing new pipe installations, are suggested,  and
methods  of computing  time  necessary to meet
specifications for a  single size pipe and for com-
binations of various size pipes are given. Field tests
show that pipe without a detectable failure will lose
less than 0.003 ft (3) of air per min per ft (2) of in-
ternal pipe surface and that any air loss exceeding
2.0 ft (3) per min can be located.

An investigation into deposition in sanitary sewers
is described. In each experiment, an 8-in pipe line
was set  at the required slope a uniform flow of
sewage was produced and sand of known particle
size was introduced at 8-ft intervals, in descending
order of size. From the  results which are shown in
tables and graphs, an equation was developed to
express the relation between the depth of flow, the
largest size particle to pass successfully through the
pipe, and the slope of the pipe. It was also found
that solids suspended in  the sewage apparently had
little effect on deposition and that pipe joints were
the principal influence in initiating deposition. It is
concluded that in designing a sewer more emphasis
should be  placed  on  joints  and construction
techniques than on minimum pipe grades.

This paper points out the importance of infiltration
in sanitary sewers. The degree of infiltration is in-
fluenced by such variables as climate, soil charac-
teristics, ground water table position, materials of
construction, vegetation, and the existence  of il-
legal connections.  In this investigation  submer-
gence tests  were made on clay and concrete pipe
using jute, cement, cold  mastic,  hot pour asphalt,
rubber gasket, and PVC jointing materials.  It was
indicated that the newer joints have much less infil-
tration than the older ones. The author stresses the
importance  of building sewers with materials that
will slow down infiltration, with joints that will stay
tight and with bedding and backfill conditions that
will prevent future movement  of the  pipe. Illegal
connections should be eliminated.

This is a discussion of the conduct and findings of a
study of a sewer district with a present population
of  50,000  (70,000  ultimate)  located  in  the
metropolitan area of Kansas City, Missouri. The
scope and objectives of this study as regards storm-
water infiltration  were:  '  (1)  to make a surface
drainage survey of selected areas and a surface in-
spection of the main sewers to find if any condi-
tions promote the entry of surface  water into sani-
tary sewers, and (2)  to collect and evaluate data on
sewer use and sewage flows.' A total sewer flow of
104.33 mgd (0.0215 cfs/acre) is developed during
large rain storms and it is concluded that 'even dur-
ing a period of moderate  precipitation the major
portions of the flow are from sources other than the
water-using plumbing fixtures in the residences and
public buildings within the district.' During these
periods the major source of sewer flow is ground
water, presumably from foundations drains used
throughout the district. Additional  local factors in-
fluencing sewer flow are reviewed.

Recent  investigations on  sewer capacities, con-
ducted at the Ministry of Technology, Hydraulics
Research  Station,  arc summarized. Experiments
using clean,  salt-glazed,  precast  concrete, and
pitch-fibre pipes  confirmed the validity of the
Colebrook-Whitc  friction  formula  (but not the
Crimp and Bruges or Manning equations), and also
showed that pitch-fibre pipes, when  clean, have an
hydraulic capacity 5-10 per cent greater than the
others. The effect of imperfect joints in salt-glazed
pipes on the roughness coefficient was found to be
directly  related to the degree of eccentricity and
the spacing of the joints. To investigate the effect of
slime layers,   flow-velocity  measurements  were
made in 20 sewers of various ages, materials, sizes
and gradients, and the roughness coefficients were
calculated. The results,  which arc  tabulated, in-
dicate  that  slime  layers form  quite  rapidly  in
sewers,  and that  the  roughness  factor increases
with increasing thickness of the layer, giving a cor-
responding reduction in capacity.

As a sequel to studies on the  hydraulic roughness of
new sewer pipes (see Wat. Pollut. Abstr., 1963, 36,
Abstr.  No.  2021),  field experiments were carried
out to  obtain information on the  probable deteri-
oration of capacity with age and use. The studies, in
which  both  salt-velocity and radioactive-tracer
techniques  were  used (the iodine-132 method
being found most convenient for use in sewers),
were carried out at 20 sites  giving a wide range of
pipe materials, sizes, gradients, and degrees of slim-
ing; and roughness values were calculated using the
Colebrook-White equation  for  turbulent  flow.
Slime became established in  sewers after a relative-
ly short period of use  and tended to predominate
near the normal water level,  but the degree of slim-
ing  varied considerably  at the different  sites,
probably depending on the composition of  the
sewage as well as the  boundary shear.  Layers of
slime less than 1 /8-inch thick had little effect on the
resistance to flow or the capacity of the pipe,  but
above  this  level  the resistance to flow  increased
rapidly with thickness of slime.  Compared with
slime, the presence of sediment in  the invert had
more marked effects on the roughness values par-
ticularly under conditions such that standing waves
were produced.  The  effects of sediment varied
widely  depending on the 'bed form' (a function of
particle size) and the flow conditions. Based on the
experimental  results, roughness values are recom-
mended for mature  foul sewers.

Present sewerage facilities serving the Counties of
Macomb and  Wayne.  Michigan are grossly  in-
adequate. The area is drained  by  Milk river which
is very slow flowing and sometimes stagnant, and a
rapid increase in population resulting in an increase
in  the volume of storm water has augmented  the
problem. A project to improve the sewerage facili-
ties,  started in September 1958, includes the con-
struction of two pumping stations, a  main pumping
station with skimming and sedimentation tanks
located about 3/4 mile upstream from the mouth of
the Milk river and a low-lift pumping station about
1/2 mile downstream from the main pumping sta-
tion. Radial gates have been installed in the river so
that  the water between the two stations can be
changed  when  necessary. The  new Milk river
sewer, although designed primarily for storm water
use,  will carry a  small quantity of sewage  during
storm periods. Under normal  dry weather condi-
tions all sewage is discharged to the Wayne County
interceptor  system and then to the Detroit sewage-
treatment plant.

  sewers was constructed in a tunnel about 30 ft.
  below ground level. Access shafts were constructed
  of 11  ft  internal dia. reinforced concrete bolted
  segmi >iis. On completion of tunnelling operations
  they  % cro converted into drop-manholes to transfer
  the e"vss flow from the existing system down into
 the ix..  tunnel system. In  addition to the connec-
  tions U< the existing system it was necessary to in-
 clude  u number of drop-manholes in the scheme
 since it was felt that the gradients of the new sewers
 should be designed so that the velocity of flow
 would be kept below 12 ft. per second to prevent
 excessive abrasion of the tunnel by grit, etc. It was
 found thai 'he amount of noise produced by the
 flow in tl'c- drop-manholes has been low and no
 complaint*  have  been  received even though the
 manholes are sited in the  road outside residential
 property. The flow passes down a vertical cast iron
 pipe into a water cushion at the bottom of the shaft.
 The water cushions have proved successful since
 although there is a build up of grit and debris at low
 flows,  at  peak flows the debris is disturbed  and
 flushed down the pipe to the outfall.  The water
 cushions are designed in such a way that they will
 not choke up with debris during prolonged low flow
 conditions.

 Descriptors: Sewers, 'Tunnels, 'Construction.
 Identifiers: 'Storm sewers, 'Capacity.

 The Borough of Croydon on the border of Surrey
 has been carrying out a program of new building,
 including commercial  development,  which  has
 raised  a demand  for additional sewage capacity.
 Accordingly, foul  water and storm water sewerage
 has been laid down. The tunnel for the new sewers
 was sunk at a depth of 40 ft. below street level and
 was  constructed  of  precast concrete segments.
 Tunnel diameters  varied  between 6 ft.  and 7 ft. In
 the former, the foul water channel was of 24 in. dia.
 and of 27 in. ilia, in the remainder.

rain water and subsoil water, particularly by sewers
and drains from small  housing  estates  and in-
dividual dwellings. Factors to be considered in the
design of surface-water  drainage systems so that
pipes are self-cleaning are the intensity and dura-
tion of rain  fall and permeability of surfaces.
Procedure is given for disposal of water in sewerage
system or to soakaways, streams, or storage vessels.
Subsoil water is defined as the portion of rainfall
that is absorbed in the ground and its drainage is
required to increase the stability of the surface and
workability of soil and to reduce flooding. The lay-
ing of field drains and mole drains is dealt with in
relation to local conditions.

Residential land planning is going through an era of
drastic change. The creation of a better living en-
vironment is  a major challenge to  planners.  En-
gineers  are  needed  as  specialists supporting
planning activities, and as qualified planners. Many
concepts in planning  are being increasingly em-
ployed, such  as: clustering, density zoning, open
space, recreational features. Careful consideration
of economics is essential  to a successful planning
activity. No matter how well planned, a project can
fail to obtain approval from  sponsors or from
governing authorities if it is poorly explained  and
presented. Storm drainage should be planned in the
early  stages  of a project development.  Several
methods of dealing with stormwater are outlined.

36-in.  one 4-ft., and one 8-ft. dropshafts. Four 10-
in. alignment holes were drilled to a depth of 70 ft.
below  the tunnel.  These holes  acted as inverted
walls and were used to lower the water table and to
provide construction needs. A 20-ft. long mechani-
cal mole excavated a  12-ft., 3-in. opening for  the
 10-ft.  tunnel. Excavated material was transported
to a slurry box, mixed with water to constitute 20%
solids, and pumped out. Dust problems were solved
by a water-spray and air-exhaust system.  Placing
forms  and pouring concrete closely followed  the
excavation.  Only 110 to 200 ft. of unlincd tunnel
was permitted. A pneumatic  concrete  placing
machine was replaced by a Pumpcrctc machine
that cut concrete placement time in half. Vibrators
in the concrete plus some vibration in the forms

flood waters and let them discharge at a controlled
rate. The ponds are carefully fenced off and are
provided with 'leaks' at a low level, which ensuie
that they dry out a few days after rain. The second

The sewerage system for Skelmersdale New Town,

and, wherever  possible, existing combined sewers
will be replaced by separate foul and surface-water
systems. After  making a comparison between the
Road Research Laboratory  Hydrograph, and the

sewers, it was decided to adopt mainly  the Lloyd-
Davies method, but itrc R. R. L. method was used
to produce the  hydrographs required for the design
of the balancing lakes. There are  three types of
temporary treatment plant in use: one, a package-
type extended-aeration plant; the  second, an ex-
tended-aeration plani using diffused air; and the
third, a conventional  filter plant  using 'Flocor'
medium.  The final effluent is discharged to the
river Tawd- A fourth plant is planned, in the  event
of further housing development or  an increase  in
industrial flow; this will involve primary sedimenta-
tion, land treatment, and clarification of the final
effluent through a gravel bed, and the effluent will
be discharged to the river Tawd. The main sewage

Community facilities are those buildings,  works
and land areas which are devoted to public or semi-
public  uses. Included in  this catagory  are public
works and utilities to provide water, power, heat,
light,  communications, sewage  treatment, flood
control, and transportation. In  planning for com-
munity facilities, the urban planner must consider
population characteristics and projections, present
and future land use,  local governmental structures,
climate, topography, soil, and vegetation. He must
consider a community's  objectives  and financial
ability, as well as  the standards of the using agen-
cies. Community  facilities may be provided by a
local community alone, jointly by several units of
government, by higher levels  of government, by
utility companies, and by private and semi-private
agencies. These facilities  should be planned jointly
since their uses are often complementary and space
can be conserved. Problems of flood control  and
stormwater drainage systems are discussed. Provid-
ing adequate stormwater drainage  must be con-
sidered  an important part of urban  planning.
Economic and engineering aspects of the problem
are outlined.

CONSIDERATION  OF STORAGE CAPACITY

J, F. Gruhler.
Gesundheits-Ing, Vol 84,1963.

Descriptors:  Design,  "Instrumentation,  *Flood
control, 'Storm runoff.
Identifiers: "Storm sewers, Capacity.

The author describes the design of a storm-water
sewer equipped with special throttles which can be
arranged so as to use the total storage capacity of
the sewer and at the same time control the volume
of storm water leaving the system to avoid flooding.
The exact position and size of these throttles must
be  determined  experimentally,  since there  is at
present no known method for  calculating them.
The principle  of the  design   is  based  on the
establishment of equilibrium conditions, the flow of
storm water entering the system being equal to the
storage capacity of the system  minus Che storm
water leaving it, and this depends on the sewer
being filled to a certain depth.

The calculation of run-off,  which is  dependent
upon intensity, duration, and  direction of rain-
storms and slope and condition of surface of area to
be served, is a  very important factor in design of
storm sewers. Storm run-off formulae and calcula-
tion of run-off are discussed.  The authors consider
also the design  and construction of different types
of inlets and outlets for storm  sewers, design and lo-
cation of manholes, and the load-carrying capacity
of sewer pipes.

The Inlet  Method of Design for storm sewers was
developed from a continuing research project on
storm drains that has been carried on by the Johns
Hopkins University for the past 13 years. The arti-
cle reports this method has shown results closer to
and more consistent with actual conditions than
any other known design method. The  3 steps in-
volved are (I) determination of peak flows to each
inlet based on maximum 5 minute rainfall intensity;
(2) attenuating the  flow peak from sub-area  as it
moves down  the pipe; and (3) summing each sub-
area hydrograph to determine the total hydrograph
at the design  point. A simplified procedure is given
for the designs where many inlets are involved.

The Milwaukee  Sewerage  Commission  provides

the 18 municipalities located within the District as
well as for 7  contract areas located  within the
drainage area. Industries are required to separate
wastewaters for  discharge  to  storm or sanitary
sewers and where necessary to provide  prctreat-
ment.  Separation of unpolluted and slightly pol-
luted industrial wastewaters for discharge to storm
sewers is stressed to reduce the volume requiring
treatment. This  philosophy is  carried  into the
domestic  wastewater  area  and separation   is
required on private property. Concentrated waste-
waters which will not affect adversely the collec-
tion system or the treatment processes are ac-
cepted in the sanitary sewer system. Required  in-
dustrial waste pretreatmcnt facilities  are therefore
designed to remove prohibited materials  from the

In the proposed system, sewage from toilets is
discharged separately from other household waste
water by means of  a  vacuum maintained in the
sewer, using a very small quantity of water to rinse
the toilet bowl and  form a water trap. The small
 amount  of highly-concentrated sewage obtained
 would  receive  conventional  treatment.  Small-
 diameter plastic pipes form adequate sewers and
 because of the vacuum present they may be laid at
 any  gradient,  even  upwards.  The  remaining
 household   waste   waters   can   normally  be
 discharged to receiving waters without treatment,
 using  a similar sewerage system  employing an
 hydraulic vacuum principle may also be  used for
 discharge of storm waters and for conveying indus-
 trial waste waters to treatment plants.

This article points out the necessity for revamping
and extending the sewer system of the City of Erie,
Pennsylvania, due to the growth in population and
expansion of the area served by the system  in
recent years. The earlier designing did not take into
consideration the future potential of the drainage
areas, a situation which is typical in a number of
communities. A simplified sewer design method
was developed for use in extending and modifying
the storm and sanitary sewer  systems in the city
which, according to the author, has proved effec-
tive and time saving both in original design and for
checking of the  existing system. The method con-
sists of equating area to quantity of both sanitary
and storm flow and superimposing the information
on  any  one  of  a number of sewer design charts
available. In this case a diagram based on Kutier's
formula (n= 0.013) was  selected.  Basic  sewer
design  principles are discussed  together  with
development and adaptation of this design method.
Drainage  areas for  both sanitary  and  storm
drainage are plotted on the sewer design chart op-
posite the corresponding quantities of sewer flow.
The sanitary portion of the chart was designed
strictly  on a population  basis, with  a  sufficient
safety factor to lead to an over-design. The chart is
designed for the minimum size storm sewers con-
sidered economically safe in the City of Erie and a
different runoff coefficient may be necessary in the
application of the method in other areas. A design
chart (based on Kuner's  formula n=  0.013)  is
presented and the use of this method is illustrated
and the  procedures followed in applying  the
method are  described. The chart  is based on an
average condition in Erie but its use in another area
would possibly  require an entirely different set of
figures  due  to  local design considerations. It  is
pointed out that, while the calculations and inten-
tions of the sewer design chart is to over-design, it
is still necessary for the final design to be checked
to  determine if the  area  under consideration  is
similar to that for which the chart was developed
and includes all the potential drainage basin.  A
chart showing a rainfall intensity curve used for
storm sewer design in Erie is also presented.

Glenrothes,  the second new  town in  Scotland,
designated under the New Towns Act of 1946, was
designated to contain an area of 5,730 acres and a
target population  of 32,000. Shopping, educa-
tional, and housing provisions are briefly discussed.
The complete  system of foul and surface water
catchments is gravity operated and it has not been
necessary to resort to either pumping or tunneling
to  maintain the gravity system. Two catchments,
one draining the northern portion of the town
(3450 acres) and one draining the southern por-
tion (2,180 acres) are described. A once  in ten-
year storm which should produce bank-full condi-
tions and flooding has been provided for by twenty
acres  of  balancing  pond  capacity  based  on an
average water depth of three ft. This provision is
estimated to cost 60,000 pounds. Design considera-
 tions are discussed for foulwatcr sewers and for sur-
 face water sewers. Foulwater runoff was  based on a
 future  water consumption  of 50  gal/hcad/day.
 Trunk  and  development  sew™  within housing
areas were designed for a peak flow of 6 D.W.F. A
discharge rate of 7 cumins/acre was calculated for
1/3 of the area; the remaining 2/3 discharging at
the rate of 1 cumin/acre. The trunk surface water
sewer was designed by the Road Research Labora-
tory's Unit Hydrograph method for a once per year
storm. This method showed an 8% saving in cost
over the previously used design method (M.O.H.
rainfall  intensity curve). Subsidiary  sewers were
designed using the rational method and Bilham's
once per year storm.  Continuing rainfall observa-
tion is expected to establish  a rainfall intensity
curve for the area.

Solution of flow problem given by Kirkham (1958)
has been worked out for submerged  drains; some
calculation examples  show  that under  certain
favorable conditions considerable increase of drain
spacing can be obtained by using deep, submerged
drains; installing of such drainage systems is possi-
ble when using plastic  pipes; carrying out drainage
works under wet conditions, as will be often neces-
sary, may in some soils impair structural stability of
soil surrounding pipes; it should be investigated in
what measure this will  be the  case when using
modern laying methods.

 Areas under construction such as new suburbs
 where all vegetation is stripped off and natural
 water courses are disturbed with streets, buildings.
 etc. are creating erosion problems with filiation of
 rivers and lakes.  Even areas designed with storm
 sewers experience this problem because of the time
 lapse to get cover, lawn, etc. to grow. A study was
 made at a 8,200 acre undeveloped area outside
 Memphis,  Tennessee,  that  is  scheduled  for
 development and the engineers recommended the
 constructing of 44 detention basins to be built at a
 cost of $1,400.000 instead of storm sewers. Basins

 The exorbitant  costs  of storm  sewer  systems
 require the decision as to the degree of protection
 to be provided against property damage, nuisance,
 and inconvenience from  surcharged sewers. The
 exact determination of the permissible frequency is
 not possible with the presently used methods, e.g.,
 empirical formula and  Rational  Method. The
 Graphic Method, as used in Germany for 50 years,
 makes it possible to determine exactly the  runoff
 for any frequency of surcharging, and this runoff is
 based on the most critical rainfall for each sewer
 stretch with regard to the relationship of rainfall in-
 tensity to rainfall duration. The Graphic Method
 permits analysis of storm water reservoirs and cal-
 culation of excess flows that are diverted over a
 weir as the rate of flow with respect to the time is
 given. The illustrated example shows that the storm
 sewer system designed  with the Rational Method
 based on a  5-year storm frequency and  15 min.
 time of concentration will actually surcharge once
 a year.

*Design, Discharge (Water).

Experiments were carried out to: (a) determine the
difference  in  composition   of  storm  sewage
discharge  from an overflow and that passed to
treatment; (b) compare the performance of the dif-
ferent types of overflow; (c) examine the effective-
ness of scum boards; and (d) measure the changes
in flow  to treatment with increasing total flow in
each structure. The types of overflow tested were:
(a) a low double side-weir; (b) a stilling pond; (c) a
vortex; and (d) a high-level side-weir with a posi-
tive flow  control. The structures tested  were
designed to operate under hydraulic conditions as
nearly identical as possible. The overflows were
designed to spill at a discharge to treatment of 1/10
the maximum discharge and, with the exception of
the low side-weir, would limit the flow to treatment
to 20% above the first spill discharge. The most
practical form seemed to be  the  round-crested
type.  Measurements  were made  of:  (a)  the
discharge  to treatment  at first  spill;  (b)  the
discharge to treatment and spill at various larger in-
coming flows; and (c) the water levels in  the over-
flow chamber for these discharges. The high side-
weir had the best general performance, second was
the stilling pond with the scum board 6 in. from the
crest, and the vortex overflow was the worst.

Identifiers: 'Combined sewers.

The quality of storm-water flow, particularly the
surplus  discharge  from  combined  sewers,  is
discussed in order to compute the required regu-
lated flow; that is, the amount of flow to be diverted
for disposal. The three elements constituting storm-
weather  flow-namely  sewage,  ground water,  and
rain water, have been considered. Coliform bac-
teria in  samples taken from streets (high runoff
coefficients) and parks  (low  runoff coefficients)
were compared.  The concentration of organic
matter in rain water is comparatively great (B.O.D.
100 to  200  ppm) being nearly as  polluted as
sewage. In regard to coliform organisms, however,
the rain  water portion of the  storm-weather flow
has  a  density  of 100 to 1,000 per ml and, ac-
cordingly, is much lower than sewage and has a
diluting effect  on the sewage.  The composition of
rain water flow varies  greatly and indefinitely.
Despite this, it is reasonable to assume a constant
composition.

POLLUTION OF THE RIVER MERSEY.

 The chief source of pollution in the River Mersey is
 from large discharges  of trade  effluents.  The
 discharge of such wastes into public sewage treat-
 ment works would  improve the condition of the
 river substantially. The desirability of treating trade
 wastes in sewage treatment plants indicates the ad-
 vantage of centralization of sewage disposal works.
 Another major source of pollution in urban areas is
 the  premature  operation  of storm sewage over-
 flows. This frequently happens in dry weather when
 streams are at low flow. The Mersey  River Board
 has  recommended  that, where  practicable, the
 overflows would not operate until at least 8 times
 dry  weather flow  has  been  reached. The  sig-
 nificance  of pollution is  evidenced  by typhoid,
 paratyphoid, and Salmonella  infections directly
 from polluted water or indirectly  from  food  con-
 taminated by it.

 Details are given of a proposal to use storm water
 and water discharged from air-conditioning plants
 to maintain the levels in  a chain of recreational
 lakes at Minneapolis, Minn., during the summer
 months. By  constructing a control dam in the lower
 portion of the existing system of drainage tunnels,
 2.6 mil. gal of water can be impounded. The dam
 will be fitted with a sluice gate which will  permit
 periodic flushing of the system, and will open auto-
 matically during heavy rainfall. The  air-condition-
 ing water is of good quality, and precautions will be
 taken to avoid interconnexions between the tunnels
 and the city's combined sewerage system. It is esti-
 mated that, in spite of variations in flow, the design
 flow of 22 ft (3) per sec can be maintained during
 most of the 100-day period when it  is intended to
 divert water to the lakes.

These reports of the Trent River Board contain sec-
tions on water resources, fisheries, and prevention
of river  pollution, including information on water
quality  (which is interpreted  in relation to the
discharge of polluting waste waters  and the effects
of severe cold weather); remedial action; and stan-
dards for effluents. Chemical data obtained in river
surveys  are  appended  and are correlated with
biological  characteristics  as represented by the
Biotic Index. The principal cause offish mortalities
was de-oxygenation of river water due to prolonged
ice and  snow cover or to the operation of storm-
sewage overflows following periods of dry weather;
the first flush  of water discharged from surface-
water sewers after a dry period is also highly pollut-
ing and  contributes to de-oxygenation. During the
first few days of April each year the rivers Tame
and Trent carry in suspension large quantities of
detached sewage fungus which, under conditions of
low flow, settle out with other suspended matter
and tend to become black in colour, following rain-
fall and  increased flow in the rivers, this material is
scoured out into suspension and exerts a considera-
ble oxygen demand thus contributing further to the
de-oxygenation. The cold winter of 1963 inhibited
nitrification  at most of the  sewage  works; this
caused increased concentrations of ammonia in the
receiving waters at a period when flow was minimal
and the frozen surface of the rivers prevented aera-

 SECOND  QUINQUENNIAL  ABSTRACT  OF

 Data are tabulated from chemical and biological
 surveys of rivers in the Trent watershed in  the
 period 1957-1962, and the percentage change in
 composition between 1951 and 1962 is estimated
 for various sampling points. The condition of the
 various stretches of watercourses is indicated on a
 map using a colour-coding scheme. At  present.
 about 80 per cent of the streams in the watershed
 are reasonably clean and of some use to the com-
 munity, but there are still about 150 miles of water-
 course which are badly polluted. Only 60 per cent
 of the sewage effluents reach the requirements set
 by the River Board but the treatment facilities arc
 being improved gradually. Factors contributing to
 the deterioration of surface waters are discussed,
 including the delay in constructing water-treatment
 facilities for new housing and industrial develop-
 ments, increasing volumes of effluent and increas-
 ing abstractions of water (which increase the ratio
 of used matural water in the streams), and increas-
 ing volumes of storm run-off for which there is in-
sufficient sewer capacity, especially in older urban
sewerage systems which  do not provide capacity
for six or even three times dry-weather flow. Where
it  is not  practicable to  improve conditions in
streams by imposing higher standards for effluents
and discharges  from storm-sewage overflows, it
may be necessary to consider 'farming the river' to
ensure the greatest possible degree of self-purifica-
tion.

Engineering studies of the Chicago Interceptor
Sewer System - including identification of system
sections which limit capacity, frequency of over-
flows, and pollution loads (P. E.) - showed an enor-
mous B. O. D. contribution (75%) from the sewage
treatment plants in relation to the overall pollution
of the waterway. Construction of additional treat-
ment plants nearer to the source of sewage load,
tertiary  treatment   facilities,   and   ultimately,
complete separation of sanitary sewage from storm

include the feasibility  of stormwater  treatment

Discharges from a  separate storm sewer system
showed mean median bacterial  counts per 100 ml
of 12 x 100,000,0.82 x 100,000, and 1.4x 100,000

for discharge from a combined system were 94  x
100,000, 2.7  x 100,000, and 5.8 x 100,000. The
ratios of fecal coliforms to fecal streptococci in the
combined and separate systems were 4.7 and 0.6,
respectively, indicating that the bacteria in  the
combined system are primarily of human origin,
whereas those in the separate system are derived
from other warm-blooded animals. Phosphates and
nitrates in combined system discharges were about
3 to 4 times greater than contents in discharges
from separate systems.

 Preliminary to the sizing of the sewers, pumping
 stations, and treatment plants of the Metropolitan
 St. Louis Sewer District's Mississippi River Pollu-
 tion Abatement Project, it was necessary to adopt a
 design criterion  for the interceptors on the com-
 bined  sewers. The amount  of pollutional load
 spilled to the river during storm water runoff was
 computed for  interceptors  of   three different
 capacities when functioning under rainfall condi-
 tions corresponding to those  experienced during
 1955.  Pollution  was measured in  terms of 'equil-
 valent hours of sewage flow.' It was found that with
 interceptors  having a capacity of 1.0 times peak
 sewage flow, 3.1% of the total yearly sewage flow
 would  be  spilled  during  storm water  runoff.
 Furthermore, the efficiency of the overall project
 after primary treatment would be approximately
 0.25% less with interceptor capacity of 1.0 times
peak sewage flow than with interceptor capacity of
1.25 times peak sewage flow, whereas the increase
in cost of the project, using the larger interceptors
would have been on the order of $2,800,000. The
smaller size interceptor was adopted.

OBSERVATIONS ON THE RECOVERY OF A

Descriptors:  Sampling, Water  pollution  control.

Identifiers: Derbyshire (Great Britain).

Until 1957 the lower reaches of the river Derwent,
Derbyshire,  were heavily polluted with effluents
from Derby  sewage works and from  an industrial
plant and with heated cooling water from the latter
and from a  power plant; in 1957, a new sewage
works was put in operation to treat  both sewage
and the industrial waste water and cooling towers
and recirculation systems were installed to control
the heated discharges. Since then, several biologi-
cal surveys of the river above and below the sewage
works have been carried out; results are tabulated
and discussed. Immediately after the removal of the
gross pollution there was a dramatic recovery in the
condition of the river, but this was followed by a
period of fluctuating conditions and there  is now a
uniformly poor fauna of tolerant species at all sta-
tions in spite of the chemical evidence that the river
is cleaner above the sewage works than below it; it
is concluded that no further improvement can be
expected  until  upstream sources  of  pollution
(mostly small sewage works  and storm-sewage
overflows) are improved and the flushing of pol-
luted tributaries is prevented.  Particular attention
has been paid to the  Oligochacta in the river, and
the results  confirm  that these organisms, when
identified to species and estimated quantitatively,
can be useful in assessing pollution.

 THE  DETERGENT   CONTENT   OF  RIVER
 WATER AS A FUNCTION OF WATER FLOW,
 W. Bucksteeg, and N. Wolter.
 Water Res, Vol 1, pp 325-333,1967.

 Descriptors: "Storm runoff, Outlets, "Detergents,
 Water pollution, 'Waste dilution.

 The content of detergent in river water is lowered
 as the water flow increases because of the dilution,
 but the total amount of detergents, or the load,
 rises. This increase is caused by the discharge of
 sewage  without biological  treatment  through
 stormwater outlets and by the reduction of the re-
 tention-time in the river during the high flow. Both
 factors diminish the possibility of biological decay.
 so that the relationship between water flow and de-
 tergent load is a result of more or less complete
 biodegradation. It is influenced by the temperature
 and degradability of the detergents. The introduc-
 tion of soft detergents since October 1964 has
 caused an important decrease in detergents at low
 and medium water flows. The advantage of soft de-
 tergents is theirefore masked by the growth of de-
 tergent use in recent years.

separate discharges was about 20 percent of that in
the combined discharges. Concentrations lessened
as discharge progressed. Values  for  total  and
volatile suspended solids and for total and volatile
setteable solids were higher in the separate system
because of  greater  erosion  in  hillier  terrain.
Phosphates were higher in  combined flows, but
nitrates  were lower.  Higher concentrations  also
were found  in the  combined system for phenols.
NH3-N, and organic N. In the separate system,
BOD was fairly constant throughout the year, but

Comparison of discharges  from combined and

showed that total coliform concentrations in runoff
carried by separate storm systems are about one
tenth of those  in combined sewers. Fecal coliform
densities in combined systems are about 20 percent
of total coliform densities, but are usually a lesser
percentage in  separate  systems. Fecal streptococ-
cus densities in combined systems are only about
twice those in separate systems. Ratios  of fecal
coliforms  to fecal  streptocci for the systems in-
dicate that fecal  coliforms  in  separate  sewer
discharges are primarily of non-human origin, and
those in combined  sewer discharges are of human

 past caused serious typhoid  epidemics. The buy,
 which is almost completely enclosed, being con-
 nected with  the  open sea by  only  two narrow
 passages, receives waste waters from the dockyard
 and from warships anchored in the harbour; pollut-
 ing material is also carried into the bay by run-off.
 during the heavy storms which are frequent in this
 region; and although an intercepting sewer, with an
 outfall outside the bay, has been built to divert a
 large  part of the municipal sewage, the storm-
 sewage overflows still discharge into the bay itself.
 and the water and mussels still  suffer faecal con-
 tamination, as shown by tabulated data. Although
 bacteriological examination of water in the buy be-
 fore and after a period of 5 hours' sunshine showed
 an  important reduction in  the  numbers  of
 Eschcrichicac, the bactcricida action of sea water
 is slow, especially in the case of  Salmonella, and it
 is too slow to prevent the penetration of sulmoncl-
 lac into molluscs. A plant was therefore set up ul
 Toulon for the self-purification of shellfish in clean
 sea water and the bacteriological quality of mussels
 was assessed before and after treatment, on  the
 basis  of standards proposed for the content of

The importance of collecting large volumes of
water to composite nature to obtain representative
samples is  stressed. The 5 mu  membrane filters
yield a complete recovery of nematodes. Subsur-
face drainage, surface runoff, and waste treatment
effluent are the 3 main sources of nematodes in sur-
face waters, but only the waste effluent carries high
concentrations of nematodes. Urban drainage has a
higher nematode content than that of rural area.
The nematode  load of a stream receiving rural
drainage  appears  to be related  to  the flushing
capacity of the runoff and of the stream and to the
carrying capacity of the stream. The persistence of
nematodes in streams appears to  be related to the
mean stream temperature, the stream temperature
changes, the rate of flow of the stream, and the na-
ture of the nematode population. The pattern of
seasonal  variation  in  nematode populations in
streams appears to be  the same regardless of the
source of nematodes.

Investigations on sewers draining three areas, one
in Northampton,  one in Bradford, and one  in
Brighouse resulted in data from which several
graphs and equations were derived and used to esti-
mate the effect of changes in overflow setting on
the frequency  duration and volume of discharge
from a  hypothetical overflow. The overflows at
Brighouse and  Bradford did not conform to such
ideal conditions. Calculations indicated that  the
flow at which first spill should occur might vary by
over 3%. These particular overflows are discussed
and  the various ways  of expressing  overflow
settings are  summarized. An  automatic  sampler
was used at each site for storm sewage. There was a
tendency for the  strength of sewage to  decrease
with time during  a storm. Variations in  average
composition  of storm sewage with ratio of excess
flow to total flow are given. Tables are  included of

prewar level. (2) To determine the effect of storm
water overflows on the pollution level.  (3)  To
determine the  quality  of water flowing  in  the
streams discharging into the lake. Brief description
of testing, areas tested and short tables of data are
included. Conclusions reached were that coliform
count definitely increased during wet period. For a
given  period, the number of days of rain has a
greater effect than the amount of rain which fell at

bacteriological and chemical investigations are also
given. The Eijkman test carried out at 45 degreesC
and  the determination  of  faecal streptococci
showed a decrease in faecal pollution from 195 3 to
1957, but pollution increased again in 1958. The
average chemical results also showed that pollution
was least in 1956 and 1957, and this coincided with
a reduction in the numbers of Euglenophyceae and

Two primary sources of water pollution other than
domestic  and industrial  wastewaters  are  the
discharges from combined sewer overflows and
from separate storm sewer systems. Such overflows
can contribute objectionable amounts of pollution
to receiving waters. Interceptor and wastewater
treatment plant capacity in relation to average dry-
weather flow shows that the overall efficiency of
raw sewage collection is not improved greatly once
such capacity reaches 3 x dry-weather flow. Partial
separation of stormwater by collecting street runoff
in a collection system independent of an existhu
combined system  markedly  increases pollution
control  efficiency  of  the  existing system; this
method  is about  40  percent as  costly as' total
separation.  Volumetric storage  sufficient  for  a
storm of 1.2 in/6 hr (30.5 mm/6  hr) can reduce
stormwater escaping treatment from 85 to 4O oer
cent. Chlorination of stormwater runoff or of mix-
tures of stormwater and raw sewage can reduce ef~
fectively bacterial concentrations.

 the most probable number method. These curves
 indicate the probability that water of a certain
 coliform bacteria density will be acceptable. The
 importance of volume and number of monthly sam-
 ples in determining the  risks of unknowingly ac-
 cepting waters  having high coliform  densities is
 discussed. Under present USPHS  standards,  the
 probability of  rejecting  water having a coliform
 density of I per 100 ml. is relatively constant and
 less than 0.01 for all membrane filter method and
 most probable number method day-to-day samples.
 It is suggested that greatly improved drinking water
 quality  control  be  obtained  by  examining a
 minimum  of 8  monthly 200-ml. samples by  the
 membrane filter  method for continuous surveil-
 lance. Operating characteristic curves are shown
 for monthly control periods for both the membrane
 filter method   and  the  most  probable  number
 method.

 The author discusses the discharge  of  partially-
 treated sewage and of storm  water to lakes. Ex-
 periences in various countries are quoted, and it is
 concluded that, with reasonable precautions, lakes
 could be used in England for the storage of surface
 run-off without causing  nuisance. The design and
 installation of  a module to regulate  the outflow
 from the storage lake to a stream is discussed, and a
 method and formulae are given for calculating the
 required storage capacity of a lake in  terms of the
 frequency  of  storm and  rate  of outflow  from
 storage.

Tabulated and graphical results are given of studies
carried out at Northampton over  a  period  of 2
years on the flow and composition of sewage in a
main sewer, with no overflows, particularly during
wet weather. It was found that the strength of the
storm sewage entering the system, as judged by the
B.O.D., was less at high flows, decreased with time
since the start of the storm, and increased  with
length of time since the previous storm. The storm
sewage  contained  a higher  concentration of
suspended  solids than  did  crude  sewage,  the
greatest concentration of solids being associated
with the first flush of storm sewage and this max-
imum value was greatest when the storm had been
preceded by several days of dry weather. The pol-
luting effect of the first flush of storm sewage is at-
tributed to the scouring out of grit  and organic
solids deposited in the system during  dry weather.
It was estimated that, had the system been provided
with a storm-water overflow, raising the setting of
the overflow by one times dry-weather flow would
have   roughly  the  same proportional  effect
throughout the range from 3  to 30 times  dry-
weather flow, and no substantial reduction in the
amount of polluting  matter discharged would be
achieved by a small change  in the setting. However,
the provision of storage capacity equivalent  to 2-
hour  dry-weather flow  at the overflow would
reduce the B.O.D. load discharged from an over-
flow set at 6 times dry-weather  flow by about 40
per cent, and trebling the  storage capacity would
reduce the load by a further 20 per cent of the ini-
tial value, equivalent to raising the overflow setting
to 11 times dry-weather flow. The average B.O.D.
load discharged per year from an overflow set at 6
times dry-weather flow would be nearly as great as
the B.O.D. load discharged as  sewage-works ef-
fluent during the same period if the whole flow to
treatment were discharged as effluent with B.O.D.
of 20 ppm and  the  suspended  solids  discharged
would be equivalent to 3 times the load in a sewage
effluent containing 30 ppm solids. It is stressed that
the results of this investigation cannot be applied to
other sewerage systems until comparable data are
available for other sites.

Northern Ireland.
A general report on current water quality condi-
tions in Northern Ireland at a time of intense ex-
pansion involving the growth of cities, creation of a
city, construction of a motorway network, and the
doubling  of ferry capacity between Britain and
Northern Ireland is presented. The need for future
legislation that will prevent and control pollution
from  industrial  and  agricultural  effluents  is
stressed. Where there are combined sewers, high
rainfall in some areas causes much direct pollution
from storm sewage and prevents adequate reten-
tion time of storm  water  at  the works. New
development areas have separate sewage systems.
In a few areas storm-water is settled by tanks at the
overflow, with occasional desludging.

                                               carried by storm water from sewer overflows, con-
                                               ditions of flow at overflow weirs, different methods

                                               and possible improvement. A design of overflow is
                                               suggested  in which the overflow  water passes
                                               through screens inclined at such an angle that the
                                               screening can be returned by an automatic scraper.
                                               The installation of a screening plant permits the
                                               discharge of greater quantities of storm water into a
                                               stream as the dilution necessary is less for screened
                                               than for unscreened storm water. The economics of
                                               storm water treatment are discussed.

Increasing  urban  development  may cause severe
silting in small  reservoirs downstream from such
developments. A  typical example is that of lake
Barcroft, near Washington, D. C., where 19 acre-ft
or 25,000 tons of sediment have been deposited for
each square  mile  of  completed residential con-
struction. Factors affecting sedimentation  in ur-
banized areas are listed; these are similar to those
occurring under rural conditions, but are more dif-
ficult to evaluate. Material deposited in a reservoir
after urban construction will probably be coarser
than that associated with rural conditions.

 Michigan although the costs of treatment are in-
 creasing, partly owing to deterioration  in water
 quality. Further deterioration in quality of lake and
 river water could be prevented by increased waste
 treatment, separation of sanitary and storm sewers,
 and elimination of ground-water infiltration into
 the sewerage system. It is also proposed that the in-
 creasing demand for recreational facilities could be
 met by further development of lakes and reservoirs
 within easy access, and that flood water from a loop
 of the Milwaukee river could be diverted into lake
 Michigan and used  subsequently to augment the
 river flow in dry weather.

Kansas City, Mo., is carrying out a $75 million pro-
gram to abate  pollution of the Missouri River and
its tributaries in the area. The program is financed
by revenue bonds supported by a sewer service
charge. The plan is geared to joint use of facilities
by Kansas City and the numerous adjacent mu-
nicipalities. Primary treatment of all wastewater is
now in effect. The facilities now completed include
four treatment plants and a number of pump sta-
tions, force mains, and interceptor sewers. Sewers
will  be extended to presently undeveloped areas.
Unusual features include a sewer river crossing, use
of an abandoned water main as a sewer force main,
and pumping of sludge 7 miles (11.3km) for treat-
ment at a central facility. Waste treatment is un-
likely to provide a total solution to  the Missouri
River's water quality problems. There  is no demon-
strable need or economic justification for storm-
water separation for the Missouri River. Quality of
stormwatcr overflows may compare favorably with
that of the receiving water. These overflows occur
less than four percent of the time and their pollu-
tional significance has not been demonstrated.

effects of  rain water  storage  have  always been
recognized as beneficial, depending on many fac-

simplified in that it is known that every peak of
river impurity  must be handled effectively or else
abstraction stopped.  Some  caution  is warranted
with toxic substances -nitrates,  phosphates and

In connexion with the prevention of pollution by
oil, deposited on motorways by  the  increasing
number of oil tankers, and washed-off into the
receiving waters  by rainfall, detailed studies were
carried out by the Ruhrverband on the Westhofer
motorway between  Remscheid and Kamen. Oil-
separator tanks have been installed along sections
of the new motorway before the storm sewage en-
ters the receiving water to protect numerous water
works in the lower and middle Ruhr, which serve a
large community. Based on the specifications DIN
4040 and 4043 of the Ruhrverband, these tanks are
constructed for a surface loading of 12 m per hour
and a retention period of 10 min; the calculation of
the run-off is based on 100 litre per second per hec-
tare. The  run-off values and time factor are ad-
justed to local conditions.  Secccssful operational
results showed that 6 months after installation a 4-
cm deposit of sludge and I-2m (to the third power)
of sand had collected from each influent and these
were easily withdrawn by  suction pumps. Tabu-

The  author describes by means of an example  a
method for estimating the effect of storm-water
overflows on sludge deposits in streams. From com-
parison of overflows of different types it appears
that  overflows from combined sewerage systems
with five-fold dilution add, on a yearly average, less
load to the stream than separate systems. Use of
storm-water  sedimentation tanks, the ideal solu-
tion, is not always possible. In general it is unneces-
sary  for such tanks to have  a retention period of
more than 10 min. The self-purifying power of the
stream must be taken into consideration

Bergen basin, a small arm of Jamaica Bay, N.Y., is
a tidal basin with no surface-water tributaries, but it
receives discharges of storm  sewage when the
capacity of the nearby Jamaica sewage works is ex-
ceeded during storms, and at times in hot weather
there has  been slight  odour nuisance. In 1963,
when alterations were being made to the sewage
works, all the plant effluent was discharged to the
basin for 2 weeks; at this time the influent sewage
was septic, having been stored in the intercepting
sewers for some months while the alterations were
in progress, and this caused severe pollution of the
basm with very strong evolution of hydrogen sul-
nhide. In an attempt to improve conditions, bulk
.odium nitrate was added to the basin to create
aerobic conditions in the bottom deposits and sodi-
um hypochlorite solution was also added to oxidize
die hydrogen sulphide in the water; these measures
Droved effective,  and subsequently  addition of
hvDccMorite was discontinued, but sodium nitrate

 ante of flow of 1, 10, and 100 times d.w.f. of the
 sewage. It is shown that the quality change with in-
 crease in rate of flow will depend  on the  initial
 duality of the stream. A table indicates the quality
 ofriver water below storm overflows. Because the

 onanic compounds than  fully treated  effluent
 there n a greater tendency to form fungal growths
 below overflows. The discharge of E. coli. content
 increases. The concentrations  of toxic  materials
 may  be critical from sewers containing industrial
 -Mtet Where rivers are used for direct abstraction
 of water for potable supplies, overflows cause rapid
 changes in quality. Fractured sewers can also cause
 ablution of rivers.  The discharges from 'standard'

 on wnreys of the River Trent and Tame to deter-
 nine the effect of storm discharges on these  two

The  author discusses, from personal experience
and from the literature, the amounts of rainfall for
which storm water overflows should be designed in
order to  avoid pollution of the receiving stream.
Amounts between 6-10 liters/sec./ha are suggested,
varying according to the stream, the slope of the
land, and the condition  of the sewerage system.
The figures must be tested by careful investigation.
Calculation of storm water overflows according to
amounts of rainfall is preferable to calculation by a
mixing ratio which may give a false impression of
the load of the stream.

The author discusses the polluting effects of storm-

and methods for reducing such pollution, including
the  installation of separate sewerage systems, the
use  of overflow settings higher than the conven-
tional 6 times dry-weather flow, improved design of
overflows, screening of storm sewage,  and provi-
sion of storage facilities at overflows to receive the
first flush of the discharge and return it later to the
foul sewer.  Pollution may  also  be caused  by
discharges of partially treated storm sewage  from
storm-sewage tanks at sewage works; this can be
reduced by increasing the flows to be  given full

study  recommended that  a system of  power-

with gate positions and levels  in  major  sewers
telemetered to a central control point. These 15
diversion points accounted for about 80 percent of
the overflow to the river in 1960. In 1966 the Dis-
trict received a Federal demonstration grant offer
of 50  percent for a sewer regulator project esti-
mated to cost $1,741,500. This work will  include
an evaluation of the effect on river conditions. A
supervisory control system will promote maximum
utilization of  the interceptor sewer and treatment
facilities, taking into account rainfall distribution in
the area and  other  factors. It will provide a new
technique of instantaneous observation and control
of interceptor system performance to minimize

 by the corresponding calculations. The balance of
 impurities shows that the introduction of rainwater
 settling tanks into the treatment considerably in-
 creases the efficiency  which also depends on the
 chosen critical  rainfall and the size  of the tanks.
 The (1-V4 )Q sub s infeed to the sewage plant results
 in favorable efficiency only for small critical rain-
 falls and small  tanks.  Larger tanks are best used
 when the (1+1 )Q sub s infeed to the plant is ob-
 served.  In  size  determinations,  consideration
 should preferably be given to a critical rainfall of
 10 to IS 1/s.ha. Rainwater hold-up time in the set-
 tling tanks should be at least 10 minutes. However,
 if it is possible to install a large collecting main with
 a high  threshold for the rainwater  overflow, an
 equivalent effect would be obtained with a hold-up
 time of about 3 minutes for the maximum infeed.

The author discusses the effects of pollution caused
by overflowing of storm water from a combined
sewer system. The characteristics of low intensity
storms in the Detroit area were first studied and the
results shown in graphs. It was found that runoff did
not occur unless precipitation was greater  than
0.03 in/hr and storm water would not overflow un-
less precipitation was more than 0.03 in/hr. plus the
capacity of the sewers for storm water. It was found
that intercepting sewers are  most  effective in
preventing overflow when they have a capacity of
 150%  of  the  sewage flow, and  no satisfactory
reduction  in number of duration  of overflows is
achieved by increasing the capacity to any reasona-
ble extent. The quality of the overflowing liquid va-
ries considerably and would  be highly polluting
even from a separate system, the cost of which is
not commensurate with the reduction in pollution
which  it would effect. A properly designed  com-
bined sewerage system should be about 99% effec-
tive in preventing pollution by storm water  over-
flows.

The effect of discharge of combined,  separate, or
partially separate sewer systems on river pollution
is discussed. Factors affecting the quantity of storm
sewage are rainfall and run-off, overflow devices,
and the storage capacity of sewers. Several over-
flow devices are  discussed. It is suggested that the
increase of treatment plant capacity, the provision
of  larger  sewers, and the provision  of selective
types of overflow are likely to cost much less than
the provision of completely separate systems, and
that pollution can be more effectively controlled by
these methods.

this problem by retaining storm  water overflows in
underground interceptor sewers of large diameter
250 ft. deep, where the water can be stored for fu-
ture  treatment. Milwaukee is  establishing  auto-

sure the average yearly flows and peak flows of the
sewer system as affected by rainfall in an attempt to
locate critical points where control facilities should
be installed. In addition, a 3.8  million  gallon un-

 To study the polluting effect of run-off from paved
 areas, samples of storm water collected from the
 separate  storm-water sewers in  Vasilcostrovsk,
 U.S.S.R., and of water from street rain receivers
 after paved streets had been washed with automatic
 sprinklers, were analysed; the results arc tabulated.
 Marked   fluctuations  in the concentrations of
 suspended solids arc  attributed  to the  differing
 degrees of dirtiness of different streets. Heavy rain
 did  not appear to reduce the polluting effect of
 later run-off, probably because pollution intensities
 ut the points of origin (road sweepings, products of
breakdown of pavements, and air-borne contami-
nants)  were relatively constant. Surface run-off
from cobbled streets with comparatively light traf-
fic  was much less  polluting  than  run-off from
asphalt-paved streets with heavy traffic. The need

Since it is not economically feasible to intercept
and treat all of sewage-storm water runoff mixture,
the study reports on determination of proper inter-
ception factor. Average daily sewage flow was con-
verted to an equivalent rainfall of 0.007 in/hr/acre
for the  area drained by combined sewers.  Peak
sewage  rate was taken  as 136% of average or
0.0095  in/hr/acre. Graphs  and charts show the
author's derivation of number of hours per year
sewage would be bypassed. Author's  conclusions
based on specific case of St. Louis with overflows
going to Mississippi River are that selection of in-
terceptor capacities in excess of peak dry weather
flow rate will produce an insignificantly small in-
crease in the effectiveness of pollution abatement
at a significant  increase  in the initial cost of the
facilities.

To reduce pollution of the Missouri and Mississippi
Rivers in the St. Louis metropolitan area. Mo., it is
planned to provide  primary treatment of sewage.
Most of the sewerage systems in the area are of the
combined  type,  and  the authors  describe  the
method used to determine the amount of the mix-
ture of sewage and storm water which should be in-
tercepted for treatment. As the Mississippi River
provides considerable dilution and is not used for
recreation nor as a source of water supply for some
considerable distance  below St. Louis, it  is con-
cluded that it is unnecessary to provide interceptor
capacities in excess of the peak dry weather flow.

 Attempts to  maintain the purity of Lake Thun.
 Switzerland,  have  resulted in  communal  sewage
 disposal. Owing to the geological position of the
 lake the sewage flows without pumping to the lower
 region, where it reaches the pumping station at
 Durrcnast and is then pumped into the treatment
 plant  at  Uctcndorf, near  the  Aare.  Additional
 pumping stations arc planned for Gwatt. Einigen,
 Spicz and Faulcnscc, and special reference is made
 to the problems of planning sewage works for the
 future, in which the population index should be
 considered. The author also discusses the effect of
 storm-sewage overflows on receiving waters.

Green Lake in Seattle, Wash., was studied to  find
the causes underlying its  heavy algae blooms  and
alleged condition of pollution so that its recrea-
tional potential might be realized. Data were ob-
tained on urban runoff, lake shore runoff, subsur-
face inflow, algae populations, waterfowl, composi-
tion of sediments, effect of wind-induced currents
on water quality, and requirements of competing
recreational  water  uses.  Water  and  nutrient
budgets  are presented. Nutrient additions sustain
heavy algae blooms throughout most of the year,
and little can be done to reduce these additions.
Bacterial contamination  is  directly related to
waterfowl  populations. Changes  in  physical  and
chemical water quality are caused largely by algal
growth and decay. Recommendations are given for
the addition of low-nutrient city water for dilution
purposes, for dredging, and for shoreline improve-
ments. It is recommended that increased quantities
of storm water not be added.

Survival of a fecal coliform (Escherichia coli) and a
fecal  streptococcus (Streptococcus faecalis  var.
liquifaciens) was studied through several years at
shaded and exposed outdoor soil plots. Death rates
for both organisms were calculated for the different
seasons at both sites. The 90% reduction times for
the fecal coliform ranged from 3.3 days in summer
to 13.4 days in autumn. For the fecal  streptococ-
cus, 90% reduction times were from 2.7 days in
summer to 20.1 days in winter. During summer, the
fecal  coliform survived  slightly  longer than the
fecal  streptococcus; during autumn, survival was
the same;  and  in spring  and  winter the  fecal
streptococcus survived much longer than the fecal
coliform. Both organisms were isolated from storm-
water runoff collected below a sampling site when
counts were sufficiently high in soil. Isolation was
more frequent during prolonged rains, lasting up to
10 days, than during short rain storms. There was
evidence of aftergrowth  of nonfecal cpliforms in
the soil as a result of temperature and rainfall varia-
tions.  Such aftergrowth may contribute  to varia-

which have no relation to the sanitary history of the

Comprehensive investigations were made to deter-

and make recommendations for its preservation;
some of the physico-chemical, bacteriological, and
biological results are presented in tables and dia-

curs during spring and autumn to distribute the
chemical constituents  uniformly throughout the
water column.  It  is concluded that the lake is still
oligotrophic but  precautions  must  be taken to
reduce the build-up of phosphates and nitrates in
certain areas where municipal and  trade waste
waters are discharged, particularly in the southern
basin where there appears to be a large semiper-
manent  clockwise  gyral  which tends to  prevent
dispersal of nutrients from the basin into the rest of
the lake;  chemical and biological differences
between the northern and southern basins also in-
dicate that horizontal mixing is very slow. The zone
of poor-quality water along the coast near waste
outfalls  varies  in width  depending  on  the
meteorological conditions. Preliminary action has
been taken to reduce pollution, especially  that
caused by storm-sewage overflows  and  by oily,

After reviewing briefly the work of other investiga-
te!* on the composition and strength of run-off
from urban areas, the authors describe a study car-
ried out in part of Cincinnati, where about 37 per
cent of the total drainage area is impermeable, the
remainder being lawns, parks and gardens. The
run-off had an average B.O.D. of 19 mg per litre, a
chemical oxygen demand of 99 mg per litre, a
suspended-solids content of 210 mg per litre, a tur-
bidity of 170 units and a colour of 81 units. The
run-off was also found to contain organic chlorides,
which could be derived from pesticides, and large
numbers of bacteria, although faecal streptococci
exceeded faecal colifortn organisms,  indicating
predominantly  non-human pollution. The highest
concentrations of all contaminants occurred within
the first 15 nan of the start of run-off. These results
confirm that run-off should be taken into con-
sideration when  estimating waste loadings from
urban sources, and the authors stress the need for
further studies to estimate the strength of run-off
under various conditions.

The authors give further results  of studies at Cin-
cinnati, Ohio, on the polluting  effect of run-off
from urban areas, including investigations of the
chemical  composition of the  rain falling on the
itudy area. The rain water was found to contain, on
average, 0.69 mg of inorganic nitrogen and 0.24 mg
of hydrolysable phosphate, per litre; these concen-
trations exceed the threshold values found by other
workers for the development of algal blooms. The
rain water also contained about 0.28 microgram of
organic chlorine compounds per litre; DDT, DDE,
and  benzene   hexachloride   were  identified.
Analyses  of the run-off,  as reported previously,
showed its pollution potential, and the concentra-
tions of coliform organisms exceeded the criterion
of  1000  per 100 ml recommended for bathing
waters. Preliminary laboratory experiments  on
treatment of the run-off showed that sedimentation
alone was not effective in  reducing the  BOD and
suspended-solids content.  Sedimentation for  20
min combined with  chlorination at a dose of 4.62
mg of chlorine per litre killed more than 99 per
cent of the bacteria; when the supernatant liquor
was dechlorinated, however, and kept at room tem-
perature for 24-72 hours, there was aftergrowth of
coliform organisms, though not of faecal coliform
bacteria or faecal streptococci.  This work is still

This  memorandum  explains  the  circumstances
under which sewage effluents should be required to
reach a standard better than that recommended by
the Royal Commission. In deciding the standards to
be imposed under particular circumstances, con-
sideration should be given to the probable concen-
tration of dissolved oxygen in the effluent and the
possible need for aeration; seasonal variations in
requirements; and flows to be treated, including the
proportion of storm sewage to be expected. The
only standard considered justifiable for discharges
of storm sewage is a condition limiting the content
of suspended solids, and since this concentration is
highly variable it is recommended that these  ef-
fluents should  not  be  required to conform to a
given standard (e.g. 100 mg per liter) all the time,
but provision should be made for one or two sam-
ples out of every ten, taken on different days, to ex-
ceed the limit.

Avon area, the classification of the watercourses is
compared with that reported in 1958. In the Severn
area, a high standard has been adopted for settled
storm  sewage,  limiting  the concentration  of
suspended solids  to  100 p.p.m.  based  on the
average of three consecutive samples. Owing to the
excessive amounts of suspended matter often found
in effluents from package sewage-treatment plants,
the Severn River Board request that land treatment
should be provided for these effluents. Recommen-
dations have also been made  regarding the design
of oil-storage tanks to prevent pollution caused by
accidents or misuse.

that effluents from storm-water  tanks at sewage
works  shall not  contain more than  100 p.p.m.
suspended solids.  It is not, however,  considered
practical to impose a  standard on the storm-water

Both  these  reports  contain  sections  on water

Hydrological surveys are reported for parts of the
catchments of the  rivers Bewdley and Avon. Ab-
straction of water irrigation is increasing and the
importance of providing bank storage has been
emphasized. Results of surveys of the rivers Severn
and Avon, certain of their tributaries, and  tidal
waters are given and discussed in detail in relation
to the various sources of pollution and prospects
for future improvements. It is planned to make a
complete survey of the rivers Wye and Lugg each
month, with less frequent sampling of other tributa-
ries,  and the first  two complete surveys are re-
ported and discussed. It is considered that effluents
discharged to the Wye estuary should conform to
the normal standards for a grade-one effluent, in
view of the character of the river and the mortality
of salmon in the tidal reaches nearly every summer.
A measure of control has also been extended to
estuaries in the Severn River Board area, and an
appreciable departure from the  normal working
standards  was possible  when  determining the
required standards for partially-treated sewage and
sewage-works effluents. Basic standards  for the
discharge of effluents to watercourses are also out-
lined, including those for pre-1951 discharges. In
the  case of farm waste waters, allowance is made
for the self-purification which may take place in the
ditch or stream to which the effluent is discharged.
With regard to partially-treated storm sewage, the
Severn River Board have abandoned the standard
limiting the BOD and, apart from specific standards
for toxic materials, the strength and quality of these
discharges are now controlled by a limit of 100
p.p.m. on the concentration of suspended solids.
This standard also applies in the Wye River Board
area where the concentration of sulphide  is also
limited to 1 p.p.m., as hydrogen sulphide. The stan-
dard imposed on the discharge of chlorinated water
from a swimming pool limited the concentration of
chlorine to 0.5 p.p.m., as free chlorine, and also
limited the rate of discharge to ensure that there
was sufficient dilution available  in the receiving
stream to avoid the risk of toxicity to fish. Altera-
tions in the treatment and discharge of sewage and
trade  waste  waters are  outlined,  together with
proposals for new treatment plants.

These  reports  each  contain sections on water

The basic  standards for effluents are summarized1
they have  remained unaltered except that, follow-
ing a decision by the Ministry of Housing and Local
Government, no limitation is now  imposed on the
B.O.D. of discharges of partially-treated sewage or
storm water. Progress in the construction  of works
to alleviate pollution of the Severn  river system has
been satisfactory but in many cases full advantage
of the new sewage works cannot be taken in storm
time until improvements to the  main sewerage
system have also been carried out. A number of
sewage authorities have accepted the policy of the
Severn River Board for reducing the storm product
in combined sewers by the selective elimination of
surface water, and the enlargement of main sewer
capacities  will permit closure of certain overflows.
New storm overflows are not permitted except in
exceptional circumstances.

The need for a unified approach to the planning,
construction, and operation of all water utility ser-

service, and  storm  drainage projects should be
planned on an integrated basis. New  York  State
laws and  constitutional  changes  have   been
designed to encourage an integrated approach to
the planning  of water and sewage works. Recent
legislation relating to such planning is described.
One provision would enable municipalities to ob-

'counties are increasingly becoming the focus for
providing area-wide water and sewer facilities.' A

The trend in Federal support of municipal waste-
treatment construction is toward larger annual ap-
propriations with higher levels of support for states
providing matching  funds.  States should  enact
parallel  grant-in-aid legislation  to  take  full  ad-
vantage of Federal aid in the future and maintain
an influential position in water-pollution control.
Rapid movement toward financial assistance for in-
dustrial waste treatment is not anticipated unless
the current study by the Secretary of the Interior
should add to the momentum. Effluent charges are
considered unlikely if industry responds favorably
to its responsibilities  for water-pollution control.
The  Clean  Waters  Restoration  Act  of 1966
authorized 75% grants to public bodies for projects
concerned with improved pollution control from

while a further 10.5 m.g.d. will be pumped 5 miles
through a  30 in. rising main to the main treatment
plant at Saltford. In  order to connect the new

rubber impregnated with nylon  fabric. They mea-
sure 120 x 20 feet, and stand between 6 and 7 feet
high when inflated. In operation, the  system will
work this way: storm overflow passes through a
Parshall flume where the volume is measured and
recorded.  At a predetermined level,  a butterfly
opens to  allow influent to enter a grit chamber,
where oils and grease float  to the top and are
skimmed off. The flow passes through a comminu-
tor which shreds all solids down to 3/8 inch. The
flow then moves by gravity to  the storage tanks.
When it is ready to be pumped back to the inter-
ceptor compressed air is used  to  prevent sludge
buildup.

city development of Columbia, Md., the treatment
of this runoff to remove pollutants, and its further

To reduce  pollution of the Potomac river in the
Washington metropolitan area, several counties, ci-
ties and towns have formed an  informal organiza-
tion that has adopted water quality objectives for
63 miles of the river, agreed that there should be
neither treated nor untreated waste discharges for
some 38  miles above the head  of tide-water, and
established  a Regional Sanitary  Advisory Board
which  has  developed  a comprehensive  plan for
sewage disposal. As part of this regional effort, the
District of Columbia is provided sewerage facilities
for much of the surrounding territory, including the
new Dulles International Airport  in Virginia. The
sewage works have  been expanded to provide
secondary  treatment by  the highrate  activated-
sludge  process, and it is planned to provide prelimi-
nary tanks  and chlorination facilities  for storm
flows in excess of those receiving complete treat-
ment.  The  new  sewerage  facilities are on  the
separate  system, and work has already begun on
converting  the older parts of the system from the

Because of increased  demands on treatment plants
and higher environmental standards, various solu-
tions are   considered  for  easing  the  pollution
problem in the Chicago area, including  the use of
long transmission lines to discharge digested sludge
to large areas  of marginal  agricultural soil and to
coal strip  mines.  Also  considered  is the   un-
derground  storage  of contaminated storm-sewage
overflows from combined sewers; storage would be
in a system of  tunnels and large chambers  ex-
cavated in solid rock deep under the city, and the
sewage would  be pumped to the surface for treat-
ment after storms, a more economical solution than
the provision of separate sewers. As a temporary
solution the  District  is experimenting with  the
chlorination of storm-sewage overflows. A brief re-
port is given on the need for tertiary treatment; a 2-
m.g.d. plant will be installed as an experiment at
the District's Hanover Park plant to provide tertia-
ry treatment by coagulation, chlorination, rapid
sand filtration, and final aeration.

Results arc given of further experiments at Newark,
Del., on the possibility of using excess storm run-off
to recharge ground water (see Wat. Pollut. Abstr.,
1961,  34, Abstr. No.  761).  Although  nearly
500,000 gal of water were spread in an infiltration
ditch near the municipal well field and allowed to
seep into the sub-surface, there was no indication
that any appreciable amount of water reached the
producing aquifer. Instead, a perched zone of satu-
ration was created by the presence of an impermea-
ble or slightly permeable bed above the water table.
This layer barred the downward  movement of
water so effectively that in  less than one day the
apex of the perched zone rose about  10 ft to the
level of the bottom of the infiltration ditch,  and as
more water  was added the mound of saturation
spread laterally. From these  experiments  it was
concluded that the principal  aquifer  at Newark
would not be benefited by spreading water in shal-
low infiltration ditches or basins, although the ab-
sorptive  capacity  of  the  unsaturated materials
which occur at shallow depth is sufficient to permit
the disposal of large volumes of storm water. How-
ever, the well field might be  recharged by other
methods; one possible solution would be a shallow
basin to store excess storm water both of the  land
surface and in the permeable beds at shallow depth,
and within this basin recharge shafts could be con-
structed to expose the top of the producing aquifer
and allow water from the surface and from the sand
and gravel bed  to infiltrate  through the shaft and
into the aquifer below.

The author deplores the present tendency to con-
centrate on primary treatment of sewage to reduce
the B.O.D. and  the concentration  of suspended
solids, while overlooking the need for destruction
of pathogenic bacteria and viruses. In older com-
munities with combined sewerage systems about 3
per cent of the sanitary sewage is discharged with
storm water through storm-water outfalls, and this
should also receive treatment to remove bacteria.
The author describes experiments carried out on
the chlorination of sewage alone and in admixture
with storm water. The results indicate that such
treatment  is  effective. The  amount  of  chlorine-
required for disinfection of storm water would be
about 50 per cent more than the amount required
for treatment of the dry weather flow alone.

The Milk River Drain project which serves Grosse
Pointe Woods and Harper Woods to the northeast
of  Detroit,  Mich.,   is  described.  Sewage  is
discharged to the Grosse Pointe interceptor which
discharges to Detroit municipal sewers; coml'ned
flows in excess of 8000 gal per min are diverted to a
sedimentation-skimming tank to remove sludge be-
fore discharge to Lake St. Clair. Settled sludge is
periodically flushed  from the  sedimentation tank
and discharged to the Grosse Pointe interceptor for
treatment at the Detroit sewage-treatment plant.

A sewage purification  plant  for  Milwaukee  is
described in detail. Primary treatment is provided
for an average flow of 60 mgd and can be expanded
to a dwf of 120 mgd by  the year 2000. Secondary
treatment is also planned for the future. The plant
is designed so that each part can handle the entire
flow hydraulically. Any  unit can be taken out  of
service for maintenance and the balance of units
will handle the entire  320 mgd  stormflow. There-
fore no plant bypass is needed  and no untreated
sewage flows to the lake.

This  discussion  on public  health  services  in
Crawley New Town, Sussex, includes a description
of sewerage and sewage disposal facilities. The new
sewerage  system  was designed to carry surface
water directly to local streams and the river  Mole;
the only surface water to go into the foul sewer was
to be that  from the existing combined sewers.  In
practice this system has failed and the  treatment
works, which was designed to take a storm flow of
12  m.g.d.,  has, under extreme conditions, had  to
deal with  18  m.g.d. Penstocks  had  to be fitted  to
the sewer inlets to prevent flooding at the works,
with the resultant 'backing up' of sewers in  many
parts of the town when these are closed. Various
causes of the excessive storm flow have been sug-
gested.  The new sewage works provide treatment
by  the activated-sludge  process,  with diffused-air
aeration. Sludge is digested and  used as fertilizer on
farmland.  With an effluent standard of 15 p.p.m.
suspended  solids and 15 p.p.m. BOD to maintain
and improve upon, it may soon become necessary
to duplicate the works to deal with the sewage from
a rapidly expanding population. The  master plan
for Crawley failed to make  any provision for refuse
disposal; as a result two unsatisfactory  attempts
have been made to establish controlled dumps. The
first site had to be closed when liquor draining from
it  polluted a  stream   which  developed   heavy
growths of sewage fungus. At the second site  an at-
tempt was made to terrace a hillside, but as a  result
of geological faulting local streams were again pol-
luted. This situation has been alleviated by digging
drainage trenches at the base of the hill to collect
the effluent which is then pumped back up the hill
side for treatment on  land. This has  not entirely
removed the pollution or the accompanying smell
of hydrogen sulphide, and  as a further  measure
potassium permanganate, which  precipitates the
hydrogen sulphide, is leached into the streams. The
cost  of mechanical methods of disposal are at
present prohibitive and a long-term plan for refuse
disposal is not yet possible.

The new sewage  works of  Brentwood,  Essex,
replacing the  Lapwater Hall works which served a
population of 1500, is designed to serve a popula-
tion of 8000, with a design dry-weather flow of
0.282 m.g.d.  Flows in excess of 3 times this value
are  automatically diverted  to storm  tanks from
which flows in excess of 6 times dry-weather flow
are discharged to irrigation plots and smaller flows
pass with the  settled sewage to the percolating fil-
ters. The rate of recirculation of effluent on to the
filters is also controlled automatically in relation to
the  rate  of the incoming flow. Final effluent  is
discharged  to grass plots but flows in excess of 3
times dry-weather flow are  pumped direct to the
river. Sludge  is digested and dried on  beds; liquor
from the digestion tanks and  drainage from the dry-
ing beds are re-treated with the influent sewage.

the direct application of powdered alum  to open
reservoirs for reduction of high turbidities caused
by storm run-off. This treatment has been found
useful in emergencies, satisfactory results being ob-
tained with alum doses of up to 85 p.p.m. It has also
been used successfully for treatment of storm water
before it enters the reservoirs. Experiments also
showed that the storm water could be treated with
liquid alum, and large storage tanks are being con-
structed at two sites for this purpose, to eliminate
the need for mechanically driven feeders.

In the derivation of improved methods for desig-
ning storm-water drainage systems it is important
to know the way in which the flood hydrograph (or
flood wave) is modified as it passes along a conduit
under conditions of free surface flow; and an exten-
sive study was therefore carried out using an ex-
perimental  pipeline installation in which the slope,
height, and length of peak of the input hydrograph
could be varied. For each set of conditions, depth-
time  data  were  automatically   recorded  and
analysed in terms of dimensionless parameters,
showing that the rate of lowering of the wave peak
with time and with distance is a function of the pipe
diameter, the Froude number, the depth of base
flow, and the  volume of fluid in the wave. The
volume of the wave, not its shape, is the principal
factor affecting the attenuation. The velocity of the
peak of the wave was found to be in good agree-
ment with the  Kleitz-Seddon law. The peak depth
of the wave is  a  function of the peak  discharge,
which is related to the steepness of the wave, but in
most practical cases differs  little from the normal
discharge. As dimensionless parameters were used.
the  results are  applicable to storm sewers of all
diameters and  floods of all durations  and mag-
nitudes,  provided the hydrograph is not steeper
than those studied.

Run-off from 10 units forming a 76-acre complex
watershed and from 2 units forming a 7.4-acre
complex watershed in the North Appalachian ex-
perimental watershed near Coshocton, Ohio, was
measured during storms during 1956. The partial
run-off values were used to calculate a theoretical
value for the run-off from each complex watershed,
which was compared with the observed run-off. For
the 76-acre  watershed, the observed run-off was
very much larger  than the estimated  run-off for
small storms, but the two values approached as the
storm size increased; in the case  of the 7.4-acre
watershed the estimated  value was very much
larger than the observed run-off for small storms
and almost equal to it for large storms. In order to
produce a better model for this type of calculation
it was concluded that the  question of sub-surface
run-off, partial area flow, and the influence of run-
off from the upper slopes on that from lower areas,
should be considered.

Studies have been carried out by the University of

for the interpretation of statistical analyses of the
relation between rainfall and run-off. For this pur-
pose, a  model of  an hydrological  unit  was
developed, based on a qualitative analysis of its
fundamental functional elements, and its structure
was  compared  with  that  of  a typical  regression
equation. The conditions for minimum error in the
estimates of flow from catchments were examined
and  various watersheds in different parts of the
world were investigated to test the applicability of
the equations of state developed. The advantages
of using an equation of state for hydrologic studies
in preference to wholly empirical relations derived
from more  or less arbitrary  multiple correlation
analyses are  indicated.

Land use,  among other factors,  determines the
quality of water produced. Erosion causes turbidity
and  sedimentation, lowers  water  quality,  and
damages  aquatic life habitats.  Fertilizers, pesti-

pollution. Agriculture, timber, mining, urban ru-

the amount by which calculated rates of runoff dur-

They suggest that it is due to a change in impermea-
bility of the catchment and describe an experiment,
using a sheet of plate glass as a catchment, to sup-
port their views. The Lloyd-Davies method of cal-
culation should be used, with the assumption that

Inaccuracies of present hydrology methods are out-
lined. An improvement is suggested wherein the
fact that cities have two separate and distinct storm
water drainage  systems,  a  'minor' and a 'major'
system would be  recognized. The minor  system
consists of carefully designed closed and open con-
duits and their appurtenances. The major system is
the route followed by flood or runoff waters when
the minor system is inoperable or inadequate. Ci-
ties today are overdesigning the minor systems. A
reasonable design  would provide that ordinary
vehicular access to properties be impaired no more
often than once in 2-10  yrs. Wiser use of natural
land conditions when developing the land can ob-
viate extensive storm sewer construction. Examples
are given of some methods for this  wiser use e.g.
'blue-green' land  development employing ponds
with open space for storm-flow detention.

 The author describes the development of a mathe-
 matical relation between rainfall and run-off in
 urban areas, taking into account various calculable
 characteristics of a drainage area and the retention
 action of a  sewerage system as used in the Road
 Research Laboratory hydrographic method. It is
 shown  that  the peak flow  for  any  particular
 frequency of storm depends on the time of concen-
 tration, the effective impervious area, and the total
 volume of water in the sewerage system at the time
 of peak run-off; only the last of these is difficult to
 determine, and for very large areas it is considered
 adequate to use an approximation. Having deter-
 mined the retention constant for a drainage system
 under particular conditions, it is also possible to
 draw  the   complete run-off hydrograph.  This
 method may be used in designing large sewers, but
 is not considered suitable for small ones.

was  employed to determine  run-off coefficients
using a 79-minute time of concentration, and the
average value obtained was 0.653, this value being
within the ranges recommended for combined re-

tervals and thus obscure much useful information
for the design of sewerage systems. Additional in-
formation can be obtained however  by relating

 Many  of our  urban waterfronts  are  blighted
 because of age and conditions unique to their loca-
 tion, such as vulnerability  to  flooding or surface
 water pollution. A range of actions, from simple
 clean-up to full scale clearance and relocation, can
 be   used  to  fight  waterfront   deterioration.
 Metropolitan  and  basinwide  approaches  are
 needed because frequently an individual city can-
 not control what happens upstream or on the other
 side of a river. Federal  urban renewal programs
 help to reduce the  local cost. In a metropolitan
 waterfront  renewal  program  the engineer must
 determine the condition of all shore line and the
 costs of repairing or replacing it. New  uses can be
 found  for old waterfront structures. Altering the
 amount of shore line; providing open space and ac-
 cess; reducing flood and storm damage; and renew-
 ing for  navigational, waterfront industrial  and
 recreational   uses  are also discussed. Providing
 adequate storm drainage  for the renewal area is an
 important part of  an  improvement  plan.  This
 drainage system could be  designed  to  improve
 drainage in a larger area than just the renewal pro-
 ject and the area  benefiting can share  costs.
 Aspects to  be considered in planning include in-
 creased runoff due to development  upstream, old
 dams, dredging of channels and winds. Some solu-
 tions are offered.

unsuitable for the design of suburban drainage
systems in regions where the design intensity is so
high that run-off occurs not only from the impervi-
ous area but also from the pervious area, such as
'-wns  and  gardens.  He  suggests that a better
  ethod would be to determine a design storm pat-
.-•m, subtract a loss rate curve, and translate the ex-
  •ss rain into hydrograph form using overland flow
  luations. The application of the method to condi-
  3ns in Canberra is described. Approximations are

cluded the flood response of a river to rainfall,
propagation of  a  flood  wave  along a river,
mechanism of run-off from an artificial catchment
receiving 'rain' from a sprinkler,  design of a net-
work of hydrometric stations, and  the  use  of
modem techniques, including digital and analogue
computers, to analyse hydrological data and in-
vestigate the relations between rainfall and run-off
A mathematical study was made of the flow of ir-
rigation and rain water to horizontal tube drains
and the mathematics of diffusion were applied to
the description of unsteady flow of ground water
Studies were also made on the  relation between
hydrology and water demand, particularly for ir-
rigation, and on the management and planning of
water resources, including the design and operation
of storage reservoirs. In connexion with water and
sewage treatment, model and  prototype  studies
were  made on  the  mixing characteristics  of
horizontal-flow sedimentation tanks, and work on
mixed-bed filtration led to the development of an
efficient graded filter with layers of polystyrene
anthracite, sand and garnet, the strata being graded
so that they retain their relative positions during
back-washing and so that the pore space decreases
in the direction of flow, with consequent deeper
penetration of removable material.

Rain discharge relations, especially on the surface
of rivers, play a significant role in the forecasting of
floods, because they make it possible to achieve a
maximum time advance in making the forecasts. A
model is developed (based on unit territorial and
rain relations)  to deduce the rain discharge rela-
tionships from  threshold values and  other simple
quantities. An example is given for which - on the
basis of  favorable conditions - an  approximate

 The author describes the methods developed to
 determine the relation between rainfall and run-off
 in the Upper Goulburn river catchment in  New
 South Wales, a large catchment for which records
 of stream flow and daily rainfall were available but
 there were no data on rainfall intensity. The net-
 work of official rain gauges was supplemented by
 records from privately-operated instruments; these
 had a slightly lower standard of consistency but
 were of adequate  quality for use in the analysis.
 Linear regression techniques were used to estimate
 mean winter and summer rainfalls for each station
 for a common 50-year period; isohyetal maps for
 mean seasonal  rainfalls were then  developed  by
 correlating the estimated rainfall for each station
 with its altitude and a third variable dependent on
 topography or location. About 75 per cent of the
 variation in rainfall was accounted for in this way,
 compared with 37 per cent when altitude was the
 only variable. The stream-flow record was used to
 estimate,  within  wide limits, the  meun  annual
 recharge  to ground water and to calculate the
 direct run-off from 242 storms in  47 years. The
 relation between rainfall and run-off was developed
 by multiple regression analysis, which was first used
 to compare the efficiency of different predictors of
 rainfall intensity and catchment dryness.

 from input to output exists. The proposed laborato-
 ry approach investigates basic laws and principles
 controlling mechanics of runoff from a watershed.
 It employs a watershed experimentation system
(WES) as a tool for the research. The WES is an in-
strumentation system of integrated hydraulic, elec-
tronic, and structural  design that can produce an
artificial rainfall of variable time and space dis-
tribution to move over a laboratory area of 40 by
40 ft or less; thus, it is capable of simulating a storm
moving in any direction over a testing drainage
basin constructed within the area. The experiment
is controlled electronically  by a digital computer,
and output runoff is measured by sonar detectors
which transmit information to the computer for im-
mediate recording and analysis. Various problems
being studied include the  time factor in  runoff
process, conceptual watershed roughness, and ef-
fect of storm movement on peak discharges. The
WES also may be  used to study subsurface  runoff
by employing testing basins made of porous materi-
als.

Practical procedure is demonstrated by applying
sequential generation techniques to rainfall and ru-

drainage basin systems; in this method, stochastic
process is formulated by several major components
including hourly annual storm rainfalls, abstrac-
tions, routing model, baseflow. direct runoff, and
total runoff: 1000  annual storms are generated
sequentially by Monte Carlo methods  and  then
routed through simulated basin system to produce
 1000 generated floods which are  represented  by
stochastic flow-duration curves  for use in water

A report, including tabulated and graphical results,

years on the distribution of rainfall and run-off, ef-
fective precipitation and temperature and stream
flow. The effect of these  characteristics on the
response of the water table and their relation to cli-
matic changes are discussed; it was found that the
water table tends to respond to rainfall in a charac-
teristic pattern, making it possible to predict short-
term changes in the ground-water level allowing for
weather forecasts and dry weather periods. From
these findings standard values for high medium low
and very low rainfall are derived.

When sewerage systems are being designed, the
volume  of storm water is often over-estimated
because no allowance is made for change of im-
permeability during rainfall. In addition, in large
catchment areas, heavy storms frequently cover
only part of the total catchment, and when run-off
is calculated by relating statistics of frequency, in-
tensity and duration of rainfall to impermeable area
by a time-of-concentration method, the flow may
be considerably over-estimated. The author sug-
gests methods for allowing for the change of im-

A computer controlled rainfall simulator has been
developed by Ven Te Chow of the University of Il-

tor can develop storms of any intensity pattern, re-
peat them at any interval desired over all,types of
terrain, and measure runoff from the terrain with
given conditions of absorption and other parame-
ters, to an accuracy  never before obtainable. The
rainfall can be released over any part, or all, of a
40- by 40-ft artificial terrain. Types of storms are
programmed and stored on computer tape so they
can be started, stopped, or  repeated at will. The
terrain simulated can range from lush water basin
areas to  arid desert. Water runoff  is accurately
measured. Major objective of the entire study is to
investigate basic laws of flow mechanics of surface
water over artificial watersheds. Descriptions of the

An  11 -year continuous record from  49 recorduM
rain gages on 400 square miles in central Illinois
has been used to derive characteristic area-depth
relations in heavy rainstorms for storm periodsof
30 minutes to 48 hours on areas of 50, 100, 200.
and 400 square miles. First, eight general equations
were statistically tested to determine the most ap-
propriate fitting method for the area-depth curve*
Over-all, an equation relating rainfall depth to £
square root of the area received the highest score
However,  the equation that  fit best was found to
vary with area! size, mean rainfall, and storm dura-
tion, which, in turn, reflected general trends in rdfe
live variability and skewness of the rainfall  spatial
distribution. Because of the  high degree of via-
bility in the area-depth relation between stormT
the analytical results have been presented as probaw
bility distributions for given sets of conditions with
respect  to area, storm  duration,  and  rsjnfal
volume. Thus, the  user  is provided with both
average curves and curves applicable to more ex
treme patterns of storm rainfall.

Time distribution relations have  been developed
for heavy storms on areas ranging up to 400 square
miles and presented in probability terms to provide
quantitative information on interstorm variability
id to provide average and extreme relations for
various applications of the findings.  It was found
that  the relations could  be represented best by
relating per cent of storm rainfall to per cent of
total storm time and grouping the data according to
the quartile in which rainfall was heaviest. The in-
dividual effects of mean  rainfall, storm duration,
and other storm factors were small and erratic in
behavior when the  foregoing analytical technique
was used. Basin area had a small but consistent ef-
fect upon the time  distribution. The derived rela-
tions are applicable to the Midwest and other areas
of similar climate and topography.  They  can  be
used in conjunction with published information on
spatial distributions and other storm parameters to

 Public waters often serve as the unloading place for
 rainwater  overflows  of mixed sewer systems or
rainwater mains of separate systems. In sizing such
streams, it  is difficult to follow  the usual cor-
responding methods for town drainage and Kehr's
rainwater run-off diagram does not permit the
determination of maximum run-off any more. It is
claimed that the method described has the ad-
vantage of permitting the determination of run-off
at any point in the stream and thus, also, of the
respective design flow. Moreover, it makes it possi-
ble to add new drainage areas and to determine the
volume of the permissible maximum amount and to
make corrections for the developed progress line
without too much effort.

in a drainage basin. An equation is first derived for
storage in the basin, and this equation is then com-

valid for both linear and non-linear cases. Storms
over 6 natural basins were analysed to verify the
theory; the storage and surface run-off computed

To determine  the surface  run-off resulting from
rainfall-excess  a catchment  storage model was
developed by  dividing the area into sections of
equal storage  delay  time.  Run-off was  routed
through the catchment by taking the outflow from
a section plus the rainfall-excess as the inflow to the
next section. The average delay time was shown to
be equal to the lag for a catchment, and an empiri-
cal relation was determined between the lag and
the mean  discharge for  a particular flood. The
procedure was applied to storm data recorded at
the University  of New South Wales, South Creek
experimental catchment, and the results were com-
pared  graphically  with  actual  surface run-off
hydrographs. Satisfactory agreement was obtained
except in  cases where the  hydrograph  rise was

At  Wellington,  N.Z., for  about 30 years, storm-
water  drainage  systems   have  been  designed
satisfactorily on the basis  of the runoff-estimated
by the rational  method, which assumes that the
highest peak flows from small catchments are
produced by storms of the short-duration, high-in-
tensity type,  and generally makes no provision for
prolonged falls of relatively low intensity. Data on
the  rainfall and floods in the residential suburb of
Karori and  in  the bush-covered  Wainui  water-
supply catchment area are  presented and discussed
with particular reference  to the behavior of the
run-on coefficient.  It is concluded that the short-
period high-intensity type  of storm  does  not
produce peak floods  as high as those attained  in
longer storms of more moderate intensity, and that
the  rational method is valid for designing drainage
systems for the prolonged  type of storm. The run-
off  coefficient can  be calculated with reasonable
accuracy  by  the method in the 'Provisional Stan-
dard' of the Soil Conservation and Rivers Control

uses and techniques are  described. The rational
method is briefly described. A method of graphical
correlation of observed volumes of storm run-off to
the amounts and duration of rainfall and conditions
in the basin at the time of the storm is described.
The unit hydrograph method of measuring the dis-
tribution of run-off in time is presented. Equations
and parameters are developed for this method
based on basin characteristics and other variables.
Conceptual models and hydrologic frequency are
discussed. A lengthy discussion follows the paper.

Hydrograph method of design considers changing
situation  over  drainage area and in network  of
sewers at equal intervals of time, usually of one
minute;  calculation  reflects  minute-by-minute
variation  in contributing area, rainfall intensity and
volume of water stored;  flow diagram, or hydro-
graph, is  evaluated and rate  of flow at outfall is
shown after each minute; comparison is made with
conventional rational method.

 Experimental plots were used to study the on-site

 derstorms  in the Walnut Gulch experimental
 watershed, Ariz. It was found that run-off increased
 with increase in precipitation and decreased as an-
 tecedent soil moisture  and crown spread of vegeta-

 in a step-wise multiple linear regression equation to
 determine the  importance of total quantity per

A theory has been developed, using a non-linear
approach, to account for the apparent variations in
instantaneous unit hydrographs derived from dif-
ferent storms over a given drainage basin. Excess
rainfall with a non-uniform area! and time distribu-
tion  is  transformed to a direct surface run-off
hydrograph at the basin outlet, with consideration
of the effect of both overland and  channel flows.
The characteristics of such flows vary from place to
place in any drainage basin, and their effects on the
instantaneous unit hydrograph are considered  in
terms of the translation and storage factors of these
flows over the basin. Analyses of  storms over 6
drainage basins  gave consistent results, indicating
that the proposed equation can be used satisfactori-
ly for instantaneous unit hydrographs.

 Hydrologists  use  double-mass  analysis to  verify
 consistency of precipitation or streamflow record;
 precipitation of station is plotted against combined
 precipitation  of surrounding stations; consistency
 of record is  verified if single straight line fitted
 through points is  reasonable; analysis is done on
 computer by fitting straight line and fourth-degree
 polynomial through  points  and comparing two
 sums of squares of deviations of points from fitted
 curves; if record is found to be inconsistent, it is ad-
 justed by bringing deviated  points  along desired
 single straight line; method should be of value to
 hydrologists having access to computers.

Records  of drainage, taken  from a percolation
gauge at Harlow Hill, near Harrogate, Yorks., were
compared with values for stream flow, rainfall and
run-off in the Nidd valley, Yorks., at 2 catchment
areas, Hunsingore and Howstean. It was found that
the response of percolation to rainfall was similar
to that of run-off to rainfall, and this  was particu-
larly marked if mean values were taken over a long
period. Statistical analysis showed that the relation
between run-off and measured drainage was closest
during winter and autumn, with correlation coeffi-
cients of 0.87 and 0.86 respectively; on the other
hand there  was a large discrepancy between infil-
tration at Hunsingore and  measured  drainage at
Harlow Hill. It was concluded that the percolation
gauge is not a satisfactory instrument for measuring
effective infiltration and that results obtained from
it should  be compared with run-off characteristics
when the gathering  grounds  are relatively im-
permeable.
