WATER SUPPLY OF NORFOLK, VA.
The twenty-third annual report of the water commissioners of Norfolk, Va., gives the total receipts, including a balance of $17,100.73 carried over from last year,as $125,770.92,of which $94,448.69 was from water rents; $647, from meters; and $10,853.16 from city collectors for water tax from 1889-96 inclusive. The expenditures were $103,855.59,including operating expenses of all sorts and interest on five per cent, and eight per cent bonds, $952.50—the balance on hand being $21,915.33. The additions and extensions to the f lant included an artesian well—depth at date of report 1,539 feet, with only salty water flowed; 9.965 feet of main, of which the Park Piace Company, bought and .’aid 4,800 feet in Park Piace, a new suburb of Norfolk,under the direction and supervision of Superintendent Riddle,but at no expense to the city’s water department. The total number of taps in the city is 6,663 • The pumpage was 1,410,803 000 gallons; the greatest daily pumpage was 4,766,400 gallons; the least, 3,140,000 gallons; average daily pumpage.
3 865,213 gallons; total pounds of coal consumed, 721,600. There are six pumps of the Gaskill, Worthington, Deane, and Ilolly-Gaskill (rotative) makes. The meters are few, nearly all large, controled by the city and owned by the city, which can compel their use, and any consumer can have one. The use of meters is compulsory on large consumers. There are between 170 and 180 public hydrants, and some forty private. In order to increase the efficiency of the aerating plant at Moores Bridges (where the process is controled by the New York Filter Manufacturing Company, the experiment was tired of forcing air from the air compressor directly into the delivery main at a point above 500 feet from the pumphouse. This was done by making four one-inch taps and connecting the two-inch air pipe directly with them. It was of some benefit: but how much it is difficult to say with accuracy, as it was so late in the season before the connection was made. The city authorities are casting about for a new source of water supply in case the artesian well should prove a failure (as is feared). The conditions confronting the water commissioners are those of great difficulty. The city is also at present making experiments in filtration. As yet only sand filtration has been tried.
