Increase in Great Lakes Water Supply
The Navy Department has approved plans that will result in increasing the filtered supply of water at Great Lakes, Ill., by more than 2,000,000 gallons a day. The present supply is 3,000,000 gallons and with the increase the naval station water supply will be equivalent to that of a city of 48,000 population. Changes will necessitate an expenditure of about $24,000, it is estimated. Four wood filters with a capacity of 500,000 a day will be added. These will be of the sand and gravel type. They will be fifteen feet in diameter and about seven feet high. The estimated cost is $9,000. At present the station has four concrete filters. A new 225 h. p. steam turbine pump with a capacity of 3,000 gallons per minute will take care of the additional work in pumping the water from the filters to the mains. Two 15 h. p. electric motors will pump the water from the lake to the filters. These changes will be completed within a month and will be under the supervision of Public Works Officer W. H. Allen.
The Maine Public Utilities Commission has authorized the Kittery water district to issue bonds of $200,000, the proceeds of which shall be expended for additions and improvements. Recent activities about the navy yard require greater facilities and it is proposed to raise the dams at Folly pond and lay about two miles of 16-inch and seven miles of 12-inch pipe. “The Kittery water district,” the Commission states, “is a quasi-municipal corporation which acquired the water works operating in Kittery and vicinity in 1908. The system then consisted of eight and onehalf miles of pipe and 61 takers, It now has 40 miles of pipe and 1,042 takers. It has issued bonds and notes from time to time to finance extensions and has retired, from net earnings, $85,000 of bonds and $21,500 of notes issued.”
