Waste of Water in Manhattan.
Leaks in old water mains, by which almost a million gallons of water have been lost every day probably for years, have been discovered by the Department of Water Supply in a district of the lower section of the city. The leaks were in several parts of pipes that were not recorded in the registrar’s office and have now been repaired. They were found through the water front waste detection crusade which the depart ment has been conducting for several months. On Sept. 21. the consumption in District No. 12 was gauged, and it was found that almost 1,000,000 gallons a day was not accounted for. The men next discovered three breaks in an abandoned -‘l-inch pipe connecting with the 10-inch pi|c line on Whitehall street, through which 360,000 gallons a day were going to waste. Further investigation showed a 12-inch pipe cut into the 16-inch pipe line on Whitehall street, and running parallel with it toward the river. Through this line 520,000 gallons a day were going to waste. A badly leaking gate was also found on this line. The total waste checked at these points amounts to 880,000 gallons a day, which would be 321,200,000 gallons a year The value of this water at meter rates would he $-12,710 annually. This water front work is rapidly being extended over the city. It has cost to date about $24,000, but has brought about a saving in daily consumption of nearly 10,000,000 gallons, anil to Sept. I, saved water to the value of $132,OIK). The other water waste prevention work, including the special house to house canvass, the notices sent out by the department and various other activities, has brought about a saving of about 40,000,000 gallons a day. This work has cost about $50,000, but has brought about a saving, to Sept. 1, of water worth $612,000.
