WATERWORKS SYSTEM AT ARLINGTON.

WATERWORKS SYSTEM AT ARLINGTON.

At Arlington, Mass., where Thomas Roden is superintendent of the waterworks, water is distributed to 9,700 persons out of a total population of 10,000, of whom 9,800 are on the lines of pipe, the source of supply being the Metropolitan water system. Both a high and low service are in use, and the total consumption for 1906 was 292,197,465 gals., of which 69,301,230 gals. (23.7 per cent, of the whole) passed through meters. The average daily consumption was 800,541 gals.— eighty gallons to each inhabitant; eighty-three to each consumer; and 426 to each of the 1,877 service taps (fifty-eight added during the year). The percentage of metered services is thirty-four per cent. The total mileage of cast iron and cement 12-in. to 4-in. mains is 35—757 ft. having been added during the year. As most of the cement pipes have been in use since 1H72, it is recommended that pipe of cast iron of greater diameter should be substituted for it. It is also recommended that a pipe should be laid front the pumping station direct to the standpipe. The number of hydrants set is 364; the average pressure on mains at the centre of the town is 90 lbs. on the high service and 50 on the low. The number of stop-gates in use is 302.

At Redding, Cal., the main of the new waterworks system that runs through the city is of wood. There are two pumps, one of which will be kept in reserve, as 1,250 gals, an hour are pumped by the other sufficient to supply the present wants of the people.
