Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1910 edition. Excerpt: ... which includes the yield of both 'stations constructed by S. W. Titus, is less than the total average daily consumption of the Borough in 1908. Including the estimated delivery of the Titus Stations, it appears that when all available sources in western Long Island are completely developed, an average daily supply of 180.5 mil. gal. may be obtained. Without the Titus plants the total safe yield would be only 170.5 mil. gal. per day. If two or three years of deficient rainfall should occur and ample storage is not in the meantime provided on the Ridgewood watershed, the total yield of all sources of supply might not exceed................................... 150 mil. gal. per day. Without the two Titus Stations 140 mil. gal. per day would be a fair estimate. Should a period of, say, 5 years of deficient rainfall be experienced, it is conceivable that even the above yield of 140 to 150 mil. gal. per day might not be sustained without seriously impairing the quality of the supply through the inflow of sea water to the collecting works. In Table No. 3 the estimates of safe yield of the works supplying Brooklyn Borough are given each year from 1905 to 1912 inclusive, assuming for the next 3 years a reasonable and progressive development of the available sources of supply. The above yields for conditions of normal rainfall are shown as a full jagged line on Diagram No. 2. The total yield of about 180 mil. gal. per day is believed to represent the maximum safe possibilities of the present sources of supply. Beneath this line a lighter one of the same character presents the total estimated safe yield of the works supplying Brooklyn during a long period of deficient rainfall.
