宾夕法尼亚州雷丁（Reading）向其公民提供了20％的水过滤水。在安提塔姆（Antietam）有三张开放式沙床100 x 144英尺，过滤器上的水高度为460英尺，每张床的容量为1,750,000加仑，每天。首次安装过滤器时的细菌效率为95.5％。从那以后，结果大大改善。由于工厂的建设而花费的金额为66,047.39美元。Egelman过滤器由两个开放式砂床组成40 x 55英尺。过滤器上的水高度为667.00英尺；每张床的容量，每天250,000加仑。过滤器每年成功的一年都在做得更好，细菌效率从第一年的97.4％提高到第二年的98.0％，在下一年和去年中提高了98.6％。过滤器的改善，成本为106.71美元，维持工厂的总成本为1,860.58美元。 The drainage-area of the Antietam supply is 5.4459 miles. The storage reservoir capacity is 101,000,000 gals.; elevation of waste-weir 510.2 ft. The Bernhart gravity supply has a drainage area of 2.56 sq. miles. The storage reservoir capacity is 42,000,000 gals.; elevation of waste-weir 3⅜-3 ft. The Egelman gravity supply has a drainage area of 0.60 sq. mile. The storage reservoir capacity is 6,990,000 gals.; elevation of waste-weir, 680.0 ft. The Maiden creek pumping plant supply has a drainage-area of 210.0 sq. miles. The capacity of its pumps is 30,000,000 gals, per day; mean elevation of creek, 240.0 ft. The new 15,000,000-gal. Allis-Chalmers pump has been installed, and the total pumpage during the fiscal year was 2,027,014,256 gals. The Hampden springs and Drift supplies collect water from the western slope of Mount Penn and empty into the Hampden reservoir. The average daily supply last year was 95,894 gals.— 8,796 less than in the preceding year. The Drift supplied 14,384 gals. The Hampden intermediate service distributing reservoir has a capacity of 29,100,000 gals, and is built at an elevation of 445.0 ft. The Penn street, low-service, distributing reservoirs have a capacity of 5,830,000 gals., their elevation being 345.0 ft. The Buttonwood street, high-service, distributing reservoir has a capacity of 1,022,000 gals. Its elevation is 630.84 ft. The average daily consumption during the fiscal year was 11,384,436 gals.—338,436 gals, per day more than in the previous year. The average daily per-capita consumption was 124.9 gals., or 0.5 gal. per capita more than that of the year before.
