WATER STATISTICS FROM ROCKFORD.

WATER STATISTICS FROM ROCKFORD.

For the first time in several years Rockford, Ill., has had a sufficient water supply to justify the laying of water mains. During the past year 12,520 feet of new mains were placed in position, and 4,296 feet of small or defective mains were replaced by large and proper mains; nine additional hydrants were set—making 377 in all; and 200 services were placed—the total being now 3,236. The meter work, however, has not progressed as rapidly as Supt. Kimball would have desired; still, much good work has been done in that line. The revenue received in 1899 was $40,302.87; maintenance in 1899. $75,797.61. The gross revenue per million gallons was $34 08; gross cost per million gallons, $28 38; net revenue per million gallons, $10.70. The following figures as to the water works system, which is owned by the city and was originally constructed in 1875-76, are interesting:
