Five Bay Counties-San Francisco, Alameda, San Mateo, Contra Costa Santa Clara: *Report to Spring Valley Water Company, by H. W. Chittenden, 1912. WATER CONSUMPTION Present Water Consumption Per Capita and Probable Increase The water consumption per capita in the east bay cities as shown by the records of the People's Water Company, and as reported by Mr. Dockweiler for 1910, were: Daily average consumption for year 1910 for east bay communities sup- Daily average consumption from wells in addition to above..... .19,457,687-84 G. P. D. per capita 6,900,000-30 G. P. D. per capita 26,357,687=114 G. P. D. per capita The water consumption per capita in San Francisco for 1910 was as Table VIII*.

From the report of the People's Water Company for 1915, the total consumption for 1915 was 5,861,714,000 gallons, or 16,050,000 gallons per day. Assuming that the average daily consumption from wells in addition to above was as Mr. Dockweiler reported in 1912-6,900,000 gallons per day, we have Total average daily consumption for 1915-22,950,000 G. P. D. Assuming a population_of_300,000, the daily average consumption per capita for 1915 was 54 G. P. D. Mr. Freeman estimated the probable daily average consumption per capita for the year 1950 to be from 125 to 150 gallons per day.
