There was no reported material solely related to the following sections: sewer hydraulics, combined sewers, or storm water - quality, quantity, and pollution. The present work includes 36 abstracts of documents published for the most part from July 1970 through September 1970. For convenience, the abstracts are classed in eight categories and arranged alphabetically by author and numerically by abstract number within each category. Since most of the papers fit into more than one category, a cumulative subject index at the end of the volume provides the necessary access to individual concepts and should be utilized for locating all abstracts in which this concept is significant. The numbers following an index term are the numbers for the abstracts in which this term is found. Each item includes a bibliographic citation, an abstract, and a set of indexing descriptors (subject terms listed in the WATER RESOURCES THESAURUS, November 1966 edition) and identifiers (newly suggested index terms). The most important index terms are marked by an asterisk. An author index and journal list are included for the reader's benefit. Copies of the articles abstracted in most cases can be obtained from research libraries covering water pollution or public health engineering literature. Suggestions concerning the improvement of content and format, or expansion of subject coverage in future supplements will be gratefully received. v ------- TABLE OF CONTENTS Section Title Page ABSTRACT iii FOREWORD v SUBJECT FIELDS AND GROUPS 1.

Descriptors: *Pollution abatement, *Sewage treatment, ^Equipment. Identifiers: *Wastewater Concentrator, ^Screen separator. The Wastewater Concentrator takes up little space but has the capacity to screen sudden overloads of raw sewage (2,000-3,000 gpm) during rainfall. It provides standby primary treatment by screening influent and then collecting it in an annular chamber and directing it to a discharge box at the bottom of the unit. Materials not passed discharge through a 10-inch pipe. The workings, operating cycle, and advantages of the unit are described. 002 GRID FOR RETAINING LARGE COMPONENTS OF SEWAGE IN SEWAGE PUMPING EQUIP- MENT, Neth Patents +NL 6817241. Descriptors: *Patents, *Sewage. Identifiers: *Pumping equipment, *Retaining grid. The grid is designed for insertion in a pipeline and for cleaning by backwashing. It is fabricated from a series of initially parallel plates bonded to the pipe wall at the edges. The dimensions are such that their axial length is at least 8 times the interplate spacing. 003 CATCHBASINS CLEANED FOR $3.00, Public Works, Vol 101, No 8, p 81, Aug 1970. 2 fig. Descriptors: *Cleaning, *Maintenance, Cost comparisons. Identifiers: *Suction machine, *Teaneck, New Jersey. Teaneck, New Jersey's switch from bucket cleaning of catchbasins to 1 ------- suction cleaning with a Good Roads Scavenger has reduced costs of the twice-a-year job by 80%. The rate of catchbasin cleaning has also increased considerably. The suction machine is also used to clean out manholes, to clean streets, and to pick up and dispose of leaves on streets and park grounds during autumn. 004 WASHED OUT ROAD REOPENED QUICKLY, Public Works, Vol 101, No 8, p 84, Aug 1970. 3 fig. Descriptors: Construction, *Steel pipes, installation, Construction materials. This article describes how a concrete slab deck culvert, destroyed by a flash flood, was replaced in only eleven working days with two 90-inch corrugated galvanized steel pipes. The contractor laid the pipe employ- ing all standard practices except for the special borrow gravel used for the entire fill. It is normally used only halfway up the pipe. 005 GUNITE GIVES NEW LIFE ... to an old, falling brick sewer system, William M. Englerth Am City, Vol 85, No 7, pp 101-102, Jul 1970. Descriptors: *Sewers, Construction, *Gunite, Repairing, Costs. Identifiers: Chattanooga, Tennessee, Sewer lining, Capacity. A visual inspection of the brick sewer system in Chattanooga, Tennessee resulted in its rehabilitation with pneumatically applied reinforced concrete lining, known as gunite. This repair method reduces the carrying capacity; however, the newly lined surface reduces many existing friction losses in the deteriorating conduit, and capacity in the repaired sewer is increased from the higher flow velocities. A total of $633,113.70 was needed to repair the main brick sewers in the downtown area of Chattanooga. 006 "BEEHIVES" PROTECT SNOW-REMOVAL SALT AND PREVENT WATER POLLUTION, John R. Fitzpatrick Am City, Vol 85, No 9, pp 81-83, Sep 1970. Descriptors: Control structures, *Structures, Construction, *Struc- tural design, Water pollution sources. Identifiers: Canada. 2 ------- Salt-sand piles, used as storage for a road clearing mixture during winter months in Ontario and subject to leaching by rain, will be covered so as to lessen this potential source of contamination. This article discusses the construction materials, the design dimensions, and the methods of erection for the 20 sided, cone-shaped storage structure. 3 ------- SECTION 2. Overflows and Regulation Devices 007 TECHNOLOGY: TEST COMBINED SEWER TREATMENT, Modern Power Eng, Vol 64, No 8, p 33, Aug 19 70. Descriptors: *Sewers, *Sewage treatment, ^Treatment facilities, Overflow. Identifiers: *Combined sewers, *Storm sewers, *Storm overflows, Racine, Wisconsin. Racine, Wisconsin is the test area for a system of satellite sewage treatment plants designed to eliminate the need for separating storm and sanitary sewers. The process involves five satellite plants which will treat the discharge from the combined sewer overflow during periods of heavy runoff. A screen/dissolved air flotation unit will remove inorganic pollutants and suspended solids from the combined sewer overflow. 008 COMPUTER CONTROL OF COMBINED SEWERS, James J. Anderson Saint Paul, Minneapolis; Watermation, Inc, Oct 1969. 19 p, 26 fig, 8 tab, 22 ref. Descriptors: *Automatic control, *Computers, *Regulated flow, *Control systems, *Pollution abatement, *Surface runoff, *Flow control, Sewers. Identifiers: *Combined sewers, ^Minneapolis - Saint Paul Sanitary District, *Urban runoff. This paper describes a unique application of digital computers for maximizing the capture of urban runoff in the combined sewer system of the Minneapolis - St. Paul Sanitary District. The real-time dynamic computer control of system overflow-regulators proved effective in helping to increase flows in interceptor sewers, thus reducing the frequency of overflows of raw sewage to the Mississippi River. Major overflow regulators were modified by replacing floats on the gates with hydraulic cylinders. Inflatable dams were installed in trunk sewer outlets. Level-sensing bubbler tubes with transducers and gate position slidewires were installed to provide sewer level and regulator status information. Control and telemetry equipment were installed in under- ground vaults. The data acquisition and control system provides both manual-remote and automatic control of the system by central computer using leased telephone wires. The author describes the river monitoring and wastewater sampling methods employed, the rain gage installations, mathematical modeling, and operating methods. He concludes that the feasibility of controlling and operating a large combined sewer system, 5 ------- using centralized computer control, has been demonstrated and that this data acquisition system will facilitate future testing of improvements in water resource management. 6 ------- SECTION 3.

Sanitary 009 RENEWAL IS VALID TERM IN BOSTON, Public Works, Vol 101, No 7, pp 70-71, Jul 1970. Descriptors: *Separation techniques, *Sewerage, *Storm drains, Construc- tion materials, Urban renewal. Identifiers: *Boston, Massachusetts, *Sanitary sewers. As part of the Bay Village urban renewal project in Boston, the old sanitary and storm drain system was replaced with separate systems. Asbestos-cement pipes were used for the first time in Boston for the sanitary sewer. Reinforced concrete was used for the new storm drain, which parallels the sanitary sewer. Other public improvements in this area include resurfacing of streets, renewal of underground facilities, and installation of brick sidewalks and gas lamps. 010 SEWERAGE PRACTICES IN THE GULF COAST AREA, John K. Mayer, Frank W. MacDonald, and Stephen E. Steimle Public Works, Vol 101, No 8, pp 71-72, Aug 1970. Descriptors: *Sewers, *Surveys, *City planning, Construction materials, Pipelines, Infiltration, Water table, Average flow. Identifiers: *Sanitary sewers, *Gulf Coast, Treatment methods. For the purpose of obtaining background information on sanitary sewers in the Gulf Coast areas, 71 municipalities and sewer districts spanning the coast from Texas through Florida were canvassed by questionnaire during the latter part of 1967 and the early part of 1968. The article 9 ------- describes the following results obtained from the survey: 1) type of sewers, 2) length of sewers, 3) pipe construction materials, 4) type of bedding used, 5) infiltration experience, 6) soil description and depth of water table, and 7) average flow and treatment used. Oil INFILTRATION IN SEPARATE SANITARY SEWERS; Determination, Economic Cost, and Correction Methods, W. G. Riddle J Water Pollution Control Fed, Vol 43, No 9, pp 1676-1683, Sep 1970. 4 fig. Descriptors: *Pollution abatement, *Surveys, *Storm runoff, *Infiltration. Identifiers: *Sanitary sewers, *Infiltration remedies. The author has investigated the matter of eliminating both infiltration and stormwater which are serious pollution and economic problems afflicting most sanitary sewer systems. He contends that the elimination of stormwater from separate sanitary sewage systems is relatively easy, inexpensive, straightforward, and requires mainly education and effort. At the same time, reduction of infiltration is found to be more difficult and expensive. Several developments for reducing leakage that are less expensive than reconstruction include: two leak reduction methods, localized pressure grouting, and recent developments in testing and detector devices (for example low pressure air testing, and a 35-mm color camera). 4c. Storm 012 STORM SEWER ASSESSMENTS, Richard R. Dague Public Works, Vol 101, No 8, pp 62-66, 118, Aug 1970. 2 fig, 2 ref. Descriptors: *Cost-benefit analysis, *Assessments, Runoff coefficient, Rainfall intensity, Drainage districts, Costs. Identifiers: *Des Moines, Iowa, *Storm sewers. The author presents a method of storm sewer assessment which was applied to a project in Des Moines, Iowa. Four benefit factors considered in apportioning property costs can be utilized in storm sewer assessment if the relative weight of each factor is determined by the relative benefit to be accrued. Other factors to be considered reflecting costs and therefore benefit are: (1) the area drained, (2) the runoff coefficient, (3) the rainfall intensity, (4) the distance to the outlet, (5) the unit pipe cost, and (6) the slope of the sewer. 10 ------- Each of these factors are discussed in relation to a sub-area. Once the dollar benefit to each sub-area is determined, the benefit to individual properties within sub-areas must be ascertained. Also, in arriving at storm sewer assessment, the benefit accruing to public property must be considered. Means for evaluating all of these factors are thoroughly described. The Des Moines procedure outlined in this article does not necessarily have application to all storm sewer special assessment problems. The test of the method will come through its application to a variety of storm sewer assessment problems along with success in the courts. 013 STORM SEWER DESIGN, F. D. Rickman Paper presented at the National Conference Committee on Electronics, American Association of State Highway Officials, Austin, Texas, May 7-8, 1968. 23 p. Descriptors: *Computers, *Computer programs, *Design, *Design criteria, Sewers. Identifiers: *Storm sewers, *Storm sewer design. The Fortran program was developed to design storm sewers from the basic data of rainfall, drainage areas, and pipe slopes and lengths. Storm sewer design lends itself to a computer operation because of the repetitive calculations involved in designing a complicated system of interconnected pipes. A program has been written in Fortran II for the IBM 1620 computer; a program for output listing was written for the IBM 1401 computer to give a better presentation to the designer and engineer. The storm sewer program is now being converted from Fortran II to Fortran IV. 014 RATIONAL "RATIONAL" METHOD OF STORM DRAINAGE DESIGN, Richard A. Rogers (discussion) J Irrigation Drainage Div, Am Soc Civil Engrs, Vol 96, No IR3, pp 342-343, Sep 1970. Original Paper: RATIONAL "RATIONAL" METHOD OF STORM DRAINAGE DESIGN, Richard A. Rogers J Irrigation Drainage Div, Am Soc Civil Engrs, Vol 94, No IR4, pp 465-480, Dec. 1968. Descriptors: *Storm drains, *Flow rates, Computer programs, Methodology, Drainage systems, Design. The writer has thus far been unable to comprehend, for the extreme case of a submerged storm system and assumed incompressible water, how 11 ------- the rate of flow out of the system at the outfall can differ from the rate of inflow at the inlets at any time. A lag time has been introduced into the computer program to allow for utilization of storage available within the system. The writer agrees with the thought that the design flows at individual points may be found from intensities occurring when peak flows reach the points, but he disagrees with the thought that the design for flows between the points can be made for the same hydraulic grade at different times. 12 ------- SECTION 5.

Identifiers: *Storm sewers. The National League of Cities (NLC) and the United States Conference of Mayors (USCM) estimated between $33 billion and $37 billion will be needed to combat water pollution between 1970 and 1976, as reported by Senator Muskie, in comparison with FWQA reports of $10 billion over the five year span, 1970-1974. The NLC-USCM survey asked for specific cost data categorized in the following manner: 1) needs for primary and secondary treatment facilities; 2) needs for tertiary treatment facili- ties; and, 3) needs for interceptor and storm sewers, including projected costs of separating storm and sanitary sewers, and/or storing storm water 15 ------- overflows. The survey covered 1,008 communities with a combined popu- lation of approximately 89.4 million. Based on the projection from this survey, the NLC and USCM estimated the total national needs for state and local water pollution control facilities for the next six years which includes a five percent inflation factor. Discussion on past, present, and future legislative action is included, and a cost chart based on survey results is given. 017 STORM DRAINAGE FACILITIES, UNION COUNTY, NEW JERSEY, Union County Planning Board, N.

Descriptors: *Sewers, *Design, *Treatment facilities, *Waste treatment, Water quality, Standards, Drainage, Sewerage. Identifiers: Japan. Improvements of existing drainage systems and extensive development of drainage works are required on the present sewer systems in order to comply with new water quality standards. Large-scale sewerage works, planned on a basin area unit system, have more advantages because of the mixture of treated wastes produced. Advanced system engineering dealing with dynamic programming and multi-level-techniques will be employed in this sewer scheme which eventually may decide general water quality. 025 THE DESIGNATION OF THE AREA AND THE WATER QUALITY STANDARD OF THE RIVER KANO, Yoji Ogawa Kogai to Taisaku, Vol 6, No 7, pp 541-549, Jul 15, 1970. 19 ------- Descriptors: *Water pollution sources, *Water quality control, ^Standards, *Water pollution control, Urbanization. Identifiers: *Japan, *Kano River Basin. The Kano River Basin supports fresh water fish and the water is used for irrigation purposes. Industrial development and urban growth in the vicinity of the river basin have contributed to the water pollution prob- lem. The Economic Planning Agency which investigated the quality of the basin water in the years 1966 and 1967 designated the water area and the water quality standard so as to maintain water quality control. By the year 1975, the pollution degree is estimated to decrease approximately 60% with water pollution control based on the new standard. 20 ------- SECTION 8. Treatment Methods and Reuse 026 PUMP INSTALLATION FOR SEWAGE, Neth Patents +NL 6817242. Descriptors: *Patents, *Sewerage, *Pumping plants, Overflow, Pipelines. This installation is especially good for pumping sewage containing larger sized pieces without separation or processing. The collector feed pipe is connected in normal circumstances to the collecting reservoir by a feed pipe and a pump with its associated suction and delivery pipes. In exceptional conditions the system is connected via an overflow situated as close as possible above the feed pipe to the sewage pit and consists of an overflow pipe, horizontally below which is fixed a grid, and separated from the incoming liquid flow by a vertical baffle wall which lies along the diameter of the pit and above the feed pipe. 027 A PHYSICAL - CHEMICAL SYSTEM FOR TREATMENT OF COMBINED STORM SEWAGE, Committee on Sewerage and Sewage Treatment, Ralph Stone (Chairman) J Sanit Eng Div, Am Soc Civil Engrs, Vol 96, No SA4, Proc Paper 7477, pp 993-994, Aug 1970. Included in the article: "Sewerage and Sewage Treatment: State-of-the-Art Abstracts". Descriptors: *Water pollution control, *Sewage treatment, *Activated carbon, *Pilot plants, Laboratory tests. Identifiers: *Storm sewage. This is a report on ongoing research, conducted by A. J. Shuckrow, G. W. Dawson, and A. T. Brix, covering enumeration and evaluation of the factors which should affect decisions as to the degree of water pollution control required in each specific situation. Powdered activated carbon may be utilized in a physical-chemical process for the treatment of combined storm sewage. The program involves laboratory development of the process, design and construction of a 100,000 gpd mobile pilot plant, and demonstration of the process. The process involves contacting the wastewater with powdered activated carbon and subsequent coagulation with alum and a polyelectrolyte followed by high-rate tube settling. The process appears to meed the following desirable characteristics for treatment of combined storm sewage: short detention time, intermittent use with capability to tolerate widely fluctuating flows and wastewater composition, small space requirements, high quality effluent, and economical operation. Based on the labora- tory findings, the mobile pilot plant is being designed to fit into a 21 ------- standard forty-foot trailer van with the exception of the carbon regen- eration facility, which will be skid mounted. The system is designed for maximum operational flexibility and includes turbidity, pH, and flow measuring instruments in addition to the continuous organic carbon analyzer. 028 FIRESTONE INSTALLS POLLUTION CONTROL, Oil Gas J, Vol 68, No 35, P 79, Aug 31, 1970. Descriptors: *Water pollution control, *Treatment facilities, Control systems, Concrete construction, Separation techniques. Identifiers: industrial treatment, *Storm water treatment. A water pollution control system, which separates storm and industrial effluent and treats plant wastewater before release into the bayou, is being installed. This $8.8 million operation provides the Firestone plant with a separate industrial effluent collecting system and a sepa- rate storm water collecting system, thus the possibility of flushing the two systems together during a heavy rainfall is eliminated. 029 OZONATION, NEXT STEP TO WATER PURIFICATION, Rene J. Bender Power, Vol 114, No 8, pp 58-60, Aug 1970. 4 fig. Descriptors: *0zone, *Water purification, *Waste water treatment, Oxidation, Chlorination, Storm runoff. Identifiers: *0verflow purification, Philadelphia. Ozonation is an outstanding method for purifying water, because ozone is a superior oxidizing agent and oxidation helps clean water thoroughly. Workings of the two types of ozonators are diagrammed and described. Ozonation is not yet used in the U.S. to purify municipal drinking water because most state laws demand that chlorination be used. Ozonation does not replace chlorination, but it incorporates chlorine into its process in two forms. Ozonation kills bacteria and viruses faster than does chlorination; in addition, ozone does not affect water taste, and it eliminates the slight chlorine taste introduced during primary treat- ment. Ozonation costs about twice as much as chlorination, but both are very inexpensive. A U.S. trend is now towards ozonation of waste- water, and one pilot plant in Philadelphia is designed to purify combined sewer and stormwater discharge when flash floods cause untreated water and sanitary sewage to overflow into rivers. Additional uses of ozone in connection with wastewater are mentioned. 22 ------- SECTION 9. Hydrology 030 REAL-TIME COMPUTER CONTROL OF URBAN RUNOFF, George Fleming and Robert L.

Fleming: A method to calculate continuous runoff volumes preferred by the writer is to employ simulation techniques using the Hydrocomp Simulation Program which simulates the complete land phase of the hydrological cycle, and uses kinematic wave assumptions for flow in circular conduits. For purposes of the mathematical model a large scale computer could be assessed using the PDP-9 for data acquisition and control of automatic gates. McFall: The writer would like to see a breakdown of costs into the categories of 1) capital outlay, 2) equipment operating, and 3) personnel cost. 031 URBAN RUNOFF BY ROAD RESEARCH LABORATORY METHOD, D.

The writer states that the Road Research Laboratory method provides a basis for evaluation of potential drainage area responses without prior extensive collection of local urban streamflow records furnishing a simple rationale for estimating flow hydrographs. The RRL model seems advantageous from the standpoints of simplicity, ease of application, 23 ------- minimal data input requirements, and reasonable reliability of results in the common application range. 032 SURFACE RUNOFF FROM GRADED LANDS OF LOW SLOPES, J. M. Laflen and I. L. Saveson Trans Am Soc Agricultural Engrs, Vol 13, No 3, pp 340-341, 1970. 4 fig, 2 ref. Descriptors: *Mathematical studies, *Data collections, *Surface runoff, Estimating equations, Storms, Louisiana. Identifiers: *Data analysis. This paper reports on analysis of surface runoff data collected during 1962, 1963, and 1964 near Baton Rouge, La. The object of the data analysis was to develop reliable prediction equations for estimating peak rate and total amount of surface runoff from any storm. The hypothesis tested was that peak rate and total amount of surface runoff could be expressed as functions of precipitation, row slope, row length, and antecedent soil moisture. Some conclusions drawn from the experiment include: 1) the effect of antecedent soil moisture is independent of precipitation, if the peak rate of runoff is the dependent variable; 2) the effect of slope and length of surface runoff is not independent of precipitation; 3) a single, precipitation - intensity measure is sufficient for expressing the effect of precipitation on peak rate of surface runoff. 033 SIMPLIFICATION OF INTEGRATED STORMWATER PLANNING FOR MODERN MULTIPLE LAND USE IN URBAN AND SUBURBAN DEVELOPMENTS, Pennsylvania State University, University Park, Inst for Research on Land and Water Resources Brian M. Reich Mar 1970. 62 p. W70-07981, OWRR-B-OlO-PA(l), Contract DI-14-01-0001-1046. Descriptors: *Hydrology, *Storms, Design, Drainage, Storage, Hydrographs, Watersheds. Four synthetic hydrograph methods were applied on five watersheds in hopes of simplifying planning decisions for reserved space in valley bottoms of suburbia headwaters. Both hydrograph and routing procedures were programmed for digital computer evaluation for the more than 300 cases considered. General conclusions include the following: 1) no simple rules can be given on width of floodways to planners; 2) computer methods greatly facilitate routing and synthetic hydrograph computations; 3) a great need exists for data-based methods for predicting suburban design hydrographs in ungaged situations; and 4) a new course was de- veloped on urban hydrology based on the studies results. 24 ------- 034 DATA ERROR EFFECTS IN UNIT HYDROGRAPH DERIVATION, Krishan P.

Identifiers: *Error analysis, *Data analysis. The author comments upon the analysis of the errors of the first three of the four methods of unit hydrograph derivation studied in the origi- nal paper: (1) Laguerre Functions Method (LFM); (2) Harmonic Series Method (HSM); (3) Least Square Method (LSM); and (4) Gamma Distribution Method (GDM); when the basic data (the hyetograph and hydrograph) were in error. The mean errors, as a percentage, for the four methods of derivation using error-free data are presented in a table. Errors due to functional structure and flexibility of the methods are demonstrated. Further investigation is suggested concerning the fact that the derived unit hydrographs will differ more from the true ones for smaller durations of rainfall excess and errors in data. 035 URBAN RUNOFF BY ROAD RESEARCH LABORATORY METHOD, Leonard H.

Original Paper: URBAN RUNOFF BY ROAD RESEARCH LABORATORY METHOD, Michael L. Terstriep and John B. Stall J Hydraulics Div, Am Soc Civil Engrs, Vol 95, No HY6, pp 1809-1834, Nov 1969. Descriptors: *Hydrographs, *Runoff coefficient, *Evaluation, Runoff, Rational formula, Storm runoff. Identifiers: *RRL method, *Urban runoff. The authors separately discuss aspects of the article included in a previous issue on an application of the Road Research Laboratory method (RRL) for synthesizing urban runoff hydrographs to conditions at three locations in the United States. Leonard Watkins describes the use of this method in Great Britain, concluding that the amounts of runoff found by the American authors agreed with experience in Great Britain. Frank Snyder discusses the theoretical applicability and other features of the RRL method, and he concludes that more analysis is needed in regard to 25 ------- the assumption of a constant runoff coefficient equal to the percentage of impervious area connected to a storm drainage system. He also states that the applicability of the RRL method to urban basins with pervious and unconnected impervious areas for infrequent design storms is limited. Harvey Duff and George Hsieh compare the commonly-used rational method to the RRL method for predicting urban runoff. The RRL method seems to result in more accurate inflow predictions, but both methods predict runoff accurately. The rational method appears easier to use; and when the RRL method is tried, a shorter time increment is recommended. 26 ------- SECTION 10. Tunnels: Technology and Equipment 036 POTENTIAL IMPACT OF TUNNELS ON WATER POLLUTION AND FLOOD CONTROL IN THE CHICAGO AREA, Forrest C. Neil Paper presented at the Am Soc Civil Engrs Environ Meeting, Chicago, Oct 13-17, 1969. 21 p, 6 fig. Descriptors: Underground storage, *Tunnels, *Control structures, *Sewers, *Flood control, *Water pollution control, Drainage systems, Design, Storm runoff, Separation techniques. Identifiers: *Chicago, Illinois. A novel approach to the solution of water pollution and flood control problems in Chicago is described. It is part of a $2 billion, 10 year approach to meet water quality standards. The present combined sewer systems cannot handle the tremendous quantities of wastewater inputs during periods of precipitation when storm runoff is appreciable. Wastes discharged to the canal system, as a result of the overflows, are contributing to the pollution of Lake Michigan and the surrounding rivers. Sewer separation alone would not improve water quality in the waterways sufficiently to meet established standards. A separate sanitary sewer system would cost over 4 billion dollars. A system of deep tunnels for temporary subsurface storage of combined sewer over- flows is desirable. This method could be achieved at less than 25% of the cost of sewer separation, using rock mole machines. 27 ------- SUBJECT INDEX (1st Quarterly) Activated carbon 027 Coliforms 022 Analysis 020 Analytical techniques 022 Assessments 012 Automatic control 008 Average flow 010 Boston, Massachusetts 009 Canada 006 Capacity 005 Chattanooga, Tennessee 005 Combined sewers 007, 008, 015, 022 Computer programs 013, 014 Computers 008, 013 Concrete construction 028 Connecticut 018, 019 Construction 004, 005, 006, 015 Construction materials 004, 009, 010, 015 Contracts 023 Control 018 Chicago, Illinois 036 Chlorination 022, 029 Cities 016, 021 City planning 010, 016, 023 Cleaning 003 Cleveland, Ohio 023 Control structures 006, 036 Control systems 008, 028 Cost allocation 016 Cost analysis 016 Cost - benefit analysis 012 Cost comparisons 003, 016 29 ------- Cost sharing 016 Estimated costs 016 Cost trends 016 Estimating equations 032 Costs 005, 012, 016, 020 Evaluation 035 Data analysis 032, 034 Data collections 022, 032 Des Moines, Iowa 012 Flood control 036 Floods 017, 018, 019 Flow control 008 Design, 013, 014, 017, 024, 033, 036 Design criteria 013 Digital computers 030 Discharge measurement 022 Drainage 017, 018, 019, 020, 024, 033 Drainage districts 012 Drainage systems 014, 036 Effluents 022 Equipment 001, 015 Error analysis 034 Flow rates 014 Gulf Coast 010 Gunite 005 Hydraulics 030 Hydrographs 031, 033, 035 Hydrology 033 Industrial treatment 028 Industries 021 Infiltration 010, 011 Infiltration remedies 011 Installation 004 30 ------- Investigations 022 Jamaica Bay, New York 022 Overflow purification 029 Oxidation 029 Japan 025 Ozone 029 Kano River Basin 025 Laboratory tests 027 Lake Erie 023 Law enforcement 021 Legal aspects 023 Legislation 016, 021 Louisiana 032 Maintenance 003 Mathematical models 030 Mathematical studies 032 Methodology 014, 031, 034 Minneapolis - Saint Paul Sanitary District 008 New Jersey 017 Overflow 007, 015, 016, 022, 026 Patents 002, 026 Philadelphia 029 Pilot plants 027 Pipelines 010, 026 Pollution abatement 001, 008, 011 Pumping equipment 002 Pumping plants 026 Racine, Wisconsin 007 Rainfall intensity 012 Rational formula 035 Regulated flow 008 Rensselaer County, New York 020 Repairing 005 Retaining grid 002 31 ------- RRL method 031, 035 Runoff 030, 035 Runoff coefficient 012, 035 Runoff forecasting 031 Sanitary sewers 009, 010, 011 Screen separator 001 Separation techniques 009, 015, 016, 028, 036 Sewage 002, 021 Sewage disposal 020 Sewage treatment 001, 007, 027 Sewer lining 005 Sewerage 009, 015, 024, 026 Sewers 005, 007, 008, 010 013, 015, 016, 019 020, 023, 024, 036 Standards 024, 025 Steel pipes 004 Storage 017, 033 Storm drains 009, 014, 019 Storm overflows 007, 022 Storm runoff 011, 015, 016 029, 035, 036 Storm sewage 027 Storm sewer design 013 Storm sewers 007, 012, 013 016, 017, 018 Storms 017, 020, 032, 033 Storm water treatment 028 Structural design 006 Structures 006 Suction machine 003 Surface runoff 008, 032 Surveys 010, 011 Teaneck, New Jersey 003 Technical feasibility 015 Treatment facilities 007, 015, 016 023, 024, 028 32 ------- Treatment methods 010, 015 Tunnels 036 Underground storage 036 Union County, New Jersey 017 Unit hydrographs 034 Urban planning 018, 019 Urban renewal 009 Urban runoff 008, 035 Urbanization 025 Viewpoint 019 Waste treatment 024 Wastewater Concentrator 001 Waste water treatment 029 Water management (applied) 030 Water pollution 015 Water pollution control 021, 023, 025 027, 028, 036 Water pollution sources 006, 022, 023, 025 Water purification 029 Water quality 022, 024 Water quality control 021, 025 Water resources 018 Water resources development 016 Water supply 020 Water table 010 Watersheds 033 33 ------- Anderson, James J. 008 Bender, Rene J. 027 Bennett, K.
