A six inch Felton surge Suppressor Is installed at the discharge of eaoh pwsp. ?he discharge frees these pumps Is against a constant static head of ©35 feet* Their capacities are as follows} lumber of Pumps la Operation Discharge Gallons Per Minute.. Total Dynamic Head 1 2 Bk 6b5 feet 677 * i im 717 * 781 “ 22,290 §02 ? i 2b,815 839 « The Booster Pump Building is one story and of reinforced concrete construc­tion* It is divided into a pump room, circuit breaker room, battery room and supply and storage space* The pump room is equipped with a 10-ton, hand operated hoist, mounted on a hand aerated bridge crane* All of the electrical controls are located in the circuit breaker room. The booster station transformer bank is located in the grounds adjacent to the booster pump house* The transformer bank la 750 KVA, Mils Chalmers 69/b,X6kv* The Terminal Reservoirs consist of the following units! Two Reservoirs, Waste Water Pipe Line* Gates Algae Control Equipment, The Terminal Reservoirs are two separate units with a combined capacity at normal high water level of 31,517,600 gallons. Their maximum capacity, with the water surface at the lip of the emergency waste way is 36,582,900 gallons* These reservoirs are of the same type of construction as the reservoirs at the Booster Pump Station. They are constructed within a shallow out, com­pletely surrounded by fill. The bottom of each reservoir is flat and 200 feet square. The sloping walls have a total rise of 30 feet on 90 feet* At the top of the sloped sections each reservoir is 380 feet square* The lining is 2 inch Granite laid on a shallow layer of stabilised soil* The over-flow spillways empty into a concrete shaft, from which a % inch,^ reinforced con­crete pipe extends to a point on the north side of the state highway. This pipe line conveys waste water and sludge from the Water Treatment Plant* On the north side of the highway the 36 inch pipe line empties into an earth­work ditch which conveys the waste water out on to the desert to an evaporation area* A bo Inch, welded steel pipe line discharges from the bottom of eaoh of the two reservoirs to the Water Treatment Plant, with a geared slide gate at the inlet end of each* The inlet of the reservoirs from the bo inch pressure line is at elevation 2035# which is also the normal high water level in the reservoirs* At the head of this inlet is located an automatic copper sulfate feeder for the control of algae*. These reservoirs are not covered.
