(The above tabulation taken from Engineering News, Aug. 22, 1912.) A supply of 100 gallons per capita per diem is enough for all the usual needs of a municipality. In some cases the use for steam boilers, laundries, some lines of manufacturing, etc., may make some greater quantity necessary. For the Charlton Union Water District provision has been made for 200 gallons per capita per diem for 75,000 inhabitants, amounting to fifteen million (15,000,000) gallons per day. This is on the basis of twice the rate of consumption that should take place under ordinary conditions, also on an increase of 50% in the population. A water works system which will supply 200 gallons per capita per diem to 75,000 inhabitants, involves an investment in the original cost of the works as high as can be justified. SOURCE OF SUPPLY-ALPLAUS KILL The Alplaus Kill rises in the southwestern part of Saratoga county at an elevation of about 800 ft. above sea level, and flows in a southeasterly direction, entering the Mohawk river near Rexford Flats. Near Charlton the valley of the Alplaus Kill narrows sufficiently to afford a suitable and desirable dam site, while above this point the valley is broad and flat, thus affording a large basin for a storage reservoir. The drainage area or watershed above this point is approximately 25 square miles. A stream gauging station was established August 12, 1913, by the Conservation Commission in co-operation with the Water Resources Branch of the United States Geological Survey at the highway bridge crossing Alplaus Kill about 3,000 ft. below the |
