Chelsea Waterworks Report.
During the year preceding the issuing of its latest report the water department of Chelsea. Mass., extended its mains 1,487 ft. The most important extension was that of the 6-in. main in Crest avenue to the Soldiers’ home, whose elevation was so great that the water from the adjoining reservoir, not being able to flow beyond the second story, had to be pumped, at the expense of the institution, from a cistern supplied from the big main on ground outside of the building. This, also, rendered the fire protection very inadequate—only 14-lb. pressure. It is now 40 lb. The rebuilding of the railroad bridge on Washington avenue by the Boston and Maine Railroad company necessitated the relocating of the 10-in. and 6-in. mains that crossed under it. When the new bridge was nearly completed, the pipes were laid across timbers projecting from the west end. Seventy-one feet of 10-in. and 82 ft. of 6-in. pipe were used, besides the many bends in forming the different angles made necessary because of the diverting of the pipes from their original location. The cost of this work was $567.62, which was paid by the railway company. Ninety-eight new services were installed. With the constantly increasing growth of the city’s manufacturing interests, more mains and additional hydrants and sprinkler systems will be needed, and the many dead ends connected with the nearest mains. The electric surface roads are blamed for the damage done by electrolysis to many of the mains in the city. A remedy must be sought in the near future. The daily average consumption of water in Chelsea as determined by the State meters was 3,761,000 gal.; the total consumption for the year being 1,372,765,000 gal.; per-capita consumption, .99 gal. Approximately 39.99 miles of cast iron main (16-in. to 2-in.) are laid in the city; 28,500 ft. of hydrant pipe; 439 ft. of fire-pipe service: 383 ft. of 2-in. water-post pipe; 177,678 ft. (33.65 miles) of service-pipe (6-in. to 214in.) Two hundred and eighty post-hydrants 3, flush, 43 private hydrants are set, and there are 34 water-posts for street-watering carts. The range of pressure on the mains is 50 lb. to 75 lb. Of meters in use, 1,792; percentage of services metered, 27; percentage of receipts from metered water, 79; number of motors and elevators ‘in use, 6; gates in use, 450, of which only one is less than 4-in.; blow-offs in use, 44; service-taps in use, 6,603. The estimated population of the city and on the lines of pipe is 38,000. The total cost of supplying water from the Metropolitan system, including State levy per 1,000,000 gal., during the year was $51.47; figured on total maintenance, interest on bonds, etc., $60.24: total receipts for the year, $143,109.02; total expenditures, $98,089.17. George Cassell is superintendent of the waterworks system.
