TO DETECT WATER-WASTE.
Superintendent R. H. Jones, of the Norfolk, Va., water department, is successfully detecting water-waste in his city. By a system of bypass meters, and by using the existing gates as essential parts of the plant, he has located leaks aggregating 500,000 gallons per day—to about eight per cent, of the gross consumption. This represents the result of his first year’s work, and, as the Norfolk supply is both pumped and filtered, the effects of the reduction are especially farreaching from a financial point of view. Before these small meters were installed, the city was aware of the existence of leakage; but the measures then taken failed to indicate where examination and repairs were required. It may be ’dded that there is no need for using a large mmber of meters; they can be uncoupled and ransferred from point to point, as required.
A ratepayer states that the contract with San Diego, Cal., with a company to furnish it with 8.000.000 gallons per day at four cents per 1,000 gallons is only one-fourteenth the cost of water to him and his fellow townsmen in Chicago.
