% INTAKE PUMPS Intake pumps consist of six peerless deep well turbine pumps* powered by 400 HPS 4150 volt General Electric motors* Pump columns are 13 inches O.D. with flanged joints, and measure 196 feet inches from motor base to bottom of strainers. Pumps are set in two rows of three, and each three discharge through $ 16 inch pipesto a 28 inch manifold. The two discharge manifolds connect to the 40 inch W.S.P* pressure main. An 3 inch Pelton Surge Suppressor is mounted at the discharge of each pump. Motors are controlled by float switches located at the Booster Station Reservoir. The discharge capacity of the intake pumps will vary in accordance with the lake level, and can operate between the following maximum and minimum ranges.

INTAKE PUMP HOUSING The Intake Pump Housing is constructed of A.P.M. siding and roof mounted on steel frame. The pump house is equipped with a 15 ton motor operated hoist, mounted on a hand operated bridge crane for pulling the pump columns and handling the motors. INTAKE CONTROL HOUSE The intake control house is a one-story, concrete building, 19 feet 11 inches wide by 80 feet long. It is divided into.a circuit breaker room, a battery room and storage space. Control panel for the intake pumps is located in this building. PRESSURE PIPS LINS The pressure Pipe line consists of the following principal partst Pipe. Air Relief Valves. Blow-off Valves.
