READING, PA., WATER DEPARTMENT.
READING, Pa., has done much during the past year to improve its water system, and among its permanent improvements is a new 10,000,000-gallon high duty Worthington pump,whose dimensions are as follows: Two high pressure steam cylinders,each 30 inches in diameter; two low pressure cylinders, each 60 inches; two plungers, each 26 inches; diameter of high pressure piston rods scinches; of low pressure piston rods, 4.0 inches; of piston rod water cylinder, 5.5 inches; clearance high pressure cylinders. 1 1-2 per cent.; of low pressure cylinders, 1 per cent.; contact stroke, – o inches; diameter of force main at engine, 30 inches; mean distance of water in well to force valves, 21 feet; net area of plunger, 519.05 square inches; area length of stroke, 49.72 inches; gallons pumped per one count of counter, 446.88 inches. This pump was subjected to a continuous test of six hour’s duration, but was not run to its full capacity, owing to the condition of the pumping main and the deficient boiler capacity. In reporting upon its work, however, Mr. tidwin F. Smith, consulting engineer, says:
“I am glad to find from calculation of the data sent me by Mr. Chamberlain of the pump test on the 6th inst. that the Worthingtons have given the city a most excellent job of work.”
During the year 17,333 feet of new mains have been laid, and fifteen new hydrants set, and gates have been placed on all hydrant connections put in during the year. The metered service is being extended gradually among the large consumers; the increase in number in use during the past year being 19—total meters in use up to April 1, 1896, 167, varying from one-half-inch to six inch. The total consumption of water by meter amounted to 53,355.000 cubic feet ( 399,264,476 gallons), producing a revenue of $14 493.48—the average revenue per thousand gallons $0,0362, p us,per 1,000 gallons. The average daily consumption for each day in the year through meters was 1,093,875 gallons—the total daily pax capita consumption, metered and unmetered, being above 100 gallons— and the increase in revenue from the metered service was $3,-141.39. It may be added that the tests made of the per cent of error in meters set or reset in Heading from May 28 to the end of the fiscal year are tantamount in many i stances to absolute accuracy. Some ‘1 hompson and some Hersey meters showed as low as .3 per cent. When the Venturi meter system for metering daily consumption from gravity supplies is in full operation, the water department of the city will reap great benefit, as records can then be kept from which can be determined accurately the amount of water consumed each day, and valuable data will likewise be afforded in reference to what quantities may be relied upon from the city’s gravity supplies. Venturi meters have been installed at the Bernhart, Antietam, Hampton Springs, and Egelman reservoirs at a total cost of $3,145.85.
The report, adverting to the appointment of Mr. E. L. Nuebling, C. E., as the new superintendent and engineer of the system, recommends that his salary be increased and says that
‘ ‘ his services are satisfactory, and the system is receiving from him the attention necessary to meet all requirements.”
