The system of supply is pumping by steam and water-power, thirty-seven per cent, being done by the water-wheels in 1880. The available capacity of water-wheels is 36,000,000 gallons daily. During summer there is a deficiency of power. Capacity of all the pumps 71.8 million gallons. There are 16 reservoirs, with a total capacity of 200 millions. The distribution of water is divided among the various works in relation to respective cle vation. The population, in 1880, was 846,984. Miles of pipe, 746. Daily average consumption, in 1880, 57.7 millions. Largest daily consumption 80 millions. Number of meters 30. Total receipts, in 1880, were nearly 4 millions of dollars; and expenditures nearly 1400,000. Laying of water-pipes assessed on abutting property. Total profits, since 1855, over twelve millions of dollars. The pumping stations and performance for 1880 are: Brooklyn.--Water-works introduced in 1859. The system is by pumping, with reservoir distribution. The source is the southern slope of Long Island Sound, ten to twenty-two miles from East River. The water is gathered from a drainage area of 6oj4 square miles by intercepting ponds, and conducted, through masonry conduit, to the pump well, seven miles from East River. The natural flow, from these ponds, into the conduit being insufficient during summer time, pumping engines were erected, 1874, at Watts' and Smith's ponds to meet the deficiency. The storage reservoir, built in 1873--'76, has a water surface of 250 acres, and a capacity of one billion gallons. There are three low-pressure beam-engines, with a combined capacity of 44 millions daily. The distributing reservoir ...
