CARLISLE & CO. PRINTERS 1130 MISSION STREET LIBRARY 2 9 1945 ; i'-J EXCHANGE CONSTRUCTION OF A SEWER SYSTEM. DATA* A.VAII/A-Bijfe.-^-Fbrtunately very extensive studies have been mnde of this problem and printed reports of the results are available. However, all the original notes and large scale maps of existing and pro- posed sewers were destroyed in April, 1906, but the undersigned and sev- eral members of the engineering staff of the City Engineer's office were employed on the original work. The following printed reports are available. "Progress Report of the Engineers in Charge to Devise and Provide a System of Sewerage," (1892-1893), Board of Engineers, Prof. Davidson, Col. Mendell, M. Irving Scott, Marsden Manson and C. E. Grunsky. "Report Upon a System of Sewerage," C. E. Grunsky, Marsden Manson, Chas. S. Tilton, City and County Surveyor, and Rudolph Hering, Con- sulting Engineer, 1899. "Report Upon a Sewerage System for San Francisco, Cal.," by C. E. Grunsky, City Engineer. Date, June 30, 1903. Municipal Reports, San Francisco, 1902-1903. Studies and modifications of the above under the Board of Public Works, 1900-1907, by City Engineer Grunsky and Principal Assistant En- gineer Connick. These data are made use of in the preparation of this report. TOPOGRAPHY OF THE PENINSULA. The topographical features of the peninsula on which San Francisco is built have been quite fully described in the reports previously made, and are fully detailed on the printed maps accompanying these reports. The City and County is in the shape of an irregular square, with sides r early seven miles long and running north and south and east and west; cut of the northwest corner of this irregular square a smaller .one about four square miles in area, is cut out. The east and north shores on the peninsula are washed by the waters of the bay, and the west by the Pacific Ocean. The natural watersheds are, therefore, three: westwardly into the ocean; eastwardly into the bay; and northerly into the bay and Golden Gate. The ridge dividing the ocean drainage from that of the bay crosses the southern boundary of the county near its median point and extends in a nearly direct line to Fort Point. The elevations of this ridge range from 250 to 900 feet. Thus, by far the greater portion of the area permits of rnpid gravity drainage. This ridge, together with the minor subdivision ridges control the division of the city and county into sewage districts. DISPOSITION OF DRAINAGE AND SEWAGE. The topography of the peninsula of San Francisco is such that its drain- age of whatever nature must be discharged from its easterly and northerly slopes into the Bay of San Francisco and from its westerly slope into the Pacific Ocean. No other rational and economic disposition is possible. The degree of dilution secured by the solution of proper points of out- fall is such that no perceptible polutiion of the waters of the bay can result. POINTS OF OUTFALL. These may be: (1) Multiple, Or to the most direct points of discharge hi conformity with the plans more or less, followed prior to January, 1900. v.hich provided some 125 points of discharge between Hunter's Point and the Presidio, and which have resulted in the nuisances now existing on the bay frontage; or (2) They may be selected as recommended in the Teports above referred to, and which are reaffirmed in this report. 2 \V 2 & The selected points were chosen by reason of the strong tidal currents which sweep between them and the shore, thus giving maximum dilution of sewage, together with its entire removal from the shores c jd In C seTecting these points of outfall the following principles have been TO remove and suppress the present nuisances around the bay frontage from Butchertown to Washerwoman's Bay, notably at Creek, Channel street, the foot of Brannan, Washington, Pacific, Powel and other streets, by collecting the sewage in large mains and dischargm it only at selected points where tidal currents will sweep it into deep water, distribute and dilute it to the maximum extent, and thus to make the shore waters of the bay adjacent to the wharves and docks clean and pure. 2d. To preserve forever from any taint or appearance of contamina- tion the waters and shores of the beach at and south of Point Lobos. These selected points of discharge were determined upon only after a scries of observations by means of floats conducted during all stages of the tides and over a period of three months and a critical study of the results. The points at which the sewage will ultimately be discharged are: 1. Off Hunter's Point. 2. Off the northerly termination of Dupont street. 3. Off the northerly termination of Pierce street. co 4. Off Mile Rock Point. S The plans are as follows: 1. To conduct by gravity by means of sewers in Milliken street and >? Visitacion avenue, the sewage from Visitacion Valley to a temporary out- S fall in the bay just north of the southerly boundary line of the City and g County. Ij 2. To conduct by gravity all of the sewage, together with that frac- as tion of the drainage due to a rainfall of 14 of an inch in twenty-four hours g from the Hunter's Point district, as shown on the accompanying plan, the aggregate area of which is over 2,300 acres. The main sewer will commence at Mission and Springdale streets and follow along the best grades and alignments in a general easterly and southeasterly direction to Fifth avenue and H street, where it will dis- charge temporarily into the waters of the bay; eventually it is to be con- tinued to Hunter's Point, and carried into the deep waters of the bay, well off shore. Ultimately this gravity main will receive by pumping the sewage from the flat districts south of Islais Creek Channel and from those to the north of South Basin. At selected points drainage in excess of the rain- fall above noted is to be carried by relief sewers along the most direct lir.es of the bay. The temporary outfall above noted is to serve as a future &torm water outlet. NORTH POINT MAIN. This main will commence at Treat avenue and Twenty-ninth street, where it receives several sub-mains and will be located thence along the best grades and alignments to the outfall point, receiving en route the several sub^mains serving the sub-districts of this district. In this loca- tion due regard will be had to the results of studies now in progress as to the stability of the foundations at certain points. At selected points this main is to be relieved of drainage water, in excess of the rainfall named, and this excess storm water conducted by gravity relief sewers to the most convenient points of discharge in the bay or its tidal estuaries. The main will serve about eighty per cent of M262666 the present population. The separate system and pumping stations are necessitated by the following facts: Over the district east 01 Sansome and between the bases of Telegraph and Rincon hills, and over the flat area between Howard street and Central Basin, officially established grades are too low to give adequate basement and sanitary drainage; hence, these districts must be separately sewered for these purposes; and storm drain- age waters must be carried by large sewers to the most suitable and con- venient points of outfall on the water front and on Channel street. UPPER ISLAIS CREEK SEWER DISTRICTS. In the earlier studies made of the disposition of sewage from the upper Islais Creek sub-districts, preference was given to passing this sewage r.hrough the divide by tunnel and delivering it into the North Point main; and to divert surface flood waters down Islais Creek. This preference was e-iven by reason of the fact that at that time the early construction of the North Point main was probable, and that the construction of an outfall to Hunter's Point would be delayed for some definite period and a tem- porary outfall made use of at N street South and Fifth avenue South, which is an undesirable point at which to concentrate a large amount of sewage. The alternate proposition of carrying this sewage to the Hunter's Point outfall, under the changed conditions which have elapsed since these first studies were made, has not been given the necessary study by reason of lack of time. The modified route will fte more fully considered, and the conditions should be made sufficiently elastic to permit of its adoption, should these studies show such modifications to be preferable. 3. To collect and discharge by gravity mains off the northerly ter- mination of Pierce street all sew.age and drainage originating north of the summit of the ridge commencing at Black Point and encircling to the southwest and west the north slope of the bay drainage, aggregating about SOO acres. This district is designated as Harbor View district in the report of 1899. The mains necessary to drain this district are in part constructed. They are to be completed and extended to the proper point of discharge well off shore. 4. To collect by gravity mains all sewage and drainage from the entire ocean slope of the peninsula, and discharge the same at Mile Rock outfall in the ocean currents washing that point. (For details of these districts and sub-districts see the reports above referred to, and maps etc on file in the City Engineer's office, to which special reference is hereby made.) This main will commence at W street, near Forty-fifth avenue, and will extend thence northerly along the best grades and alignments to the Mile Rock outfall, receiving along its route the sub-mains from the Ocean View district, Sunset district and West Richmond district. At present the sewage from the Richmond district is being discharged into the ocean opposite the northerly termination of Twenty-seventh ave- nue, or at the southerly end of Baker's Beach. Ultimately it will be desirable to construct a tunnel and discharge this sewage at Mile Rock, the present outfall remaining in use as a point for storm water disposal. These five districts will cover the entire city and county, and the mains herein proposed will be built with a full consideration of probable increase in their population. CAPACITIES OF SEWERS. The sewers are proposed to carry the sewage and the maximum amount ol runoff due to the periods of intensely heavy rainfall indicated on the rainfall intensity diagram hereto appended. Wherever necessary the maiiis of each district are to be relieved of dis- charge in excess of sewage and one-fourth of an inch of rainfall per twenty- tour hours. This excess is to be carried by relief sewers to the most con- venient outfall point. The relief sewers will be called into use on the average less than thirty days each year, and may be expected to serve up to their full capacity about once or twice a year. Beyond the points of relief the mains will be reduced in capacity to the sewage plus the runoff due to one-fourth of an inch rainfall per twenty-four hours. The sewers herein provided for will supply the necessary outfall to all the new and growing sections of the city as well as those now quite densely built up. It is intended that by the later construction of the necessary sub-mains and laterals no portion of the City and County shall be left without proper drainage and sewerage facilities. Detailed studies are being made with a view of reducing the area of some of the pumping dis- tricts, which are served by the separate system, by the introduction of gravity pressure mains. PROPOSED SEWERS. In order to indicate clearly which sewers are recommended for early construction the following table has been prepared. The estimate of cost covers the construction of all the sewers which are recommended for im- mediate construction, even in those cases where. streets are not now ready to receive them and where several years may elapse before their construc- tion. The information in the tables relating to sewer sizes is given in detail so far as definiteness could be given to the location of sewers, except in the following cases: In the case of Yerba Buena District, a complete system of sewers for the collection of sewage proper, are recommended for immediate construc- tion, and are covered by the cost estimate. In the case of Mission Flats District, the sewers embrace the entire system of sewers for sewage proper except a few local sewers on un- improved water-front property, and embraces also the sewers at once required south of Channel street. All of the structures and devices of every kind, including manholes, connections with old sewers, relief outlets, pumping stations and out-fall works, which are necessary for the successful operation of sewers now rec- ommended for construction, are to be considered a part of these sewers and are not specifically enumerated in the following table, but are covered by the estimate of cost. Abbreviations used in the table are as follows: N. North or northerly. So. South or southerly. E. East or easterly. W. West or westerly. Br. Brick. (Brick means either brick, or concrete and brick.) Br. cone, means brick and concrete. I. S. P. Iron-stone pipe. Req. Required. Pro. Proposed. Prod. Produced. Sta. Station. R. O. W. Right-of-way. Wd. Wood. Cone. Concrete. Extd. Extended. Ret.
