WATEK TREATMENT PLAHT / The Water Treatment Plant consists of the following principal units* Two Reaction Tanks. Chemical Feed Equipment* Bight Rapid Sand filters. Four Zeolite Softeners* Chlorination Equipment. Two Clear Wells. Building. Reaction Tanks are of the up-flow variety, using Dorr Hydrotreator Equipment. The tanks are 65 feet square, with a 14§ foot side water depth. Retention at maximum flow is approximately one hour. The reaction tanks are identical and operate in parallel. The Rapid Sand Filters consist of eight separate units, with a total surface area of 5,030 square feet and a three foot sand depth. The design maximum rate of application is three gallons per square foot per minute* The back-wash rate is fifteen gallons per square foot per minute* The plant does not have a back-wash tower, back-wash water being pumped direct from the filtered water clear well through the filters. Waste wash water is reclaimed and pumped back through the reaction tanks. Water to be Zeolite softened is conveyed directly from the filter overflow to four Zeolite cells. The total surface area of the Zeolite beds is 523 square feet, with a media depth of four feet. Synthetic Zeolite is used. Zeolite treated water overflows to the smaller of the two clear wells. For the domestic water supply, filtered water and Zeolite treated water are blended to the desired hardness by an automatic tempering valve. Three small booster pumps are used to raise the pressure in the domestic water distribution system. All water is chlorinated after treatment, the chlorine being applied at each of the clear wells, which provide a brief contact period before the water is discharged to th® distribution mains. The entire plant, including building, tanks and clear wells, is of reinforced concrete construction. It is completely fireproof and of excellent design. ELECTRICAL TRANSMISSION & CONTROL LINES Electrical Transmission and Control Lines consist of Electric Transmission Line, Telephone Control System and Transformer Bank. The electrical transmission line to the Booster Pump Station is 69 kv, is 62,770 feet long with 100 structures, and with 2/07-strand copper cables. From the transformer bank at the Booster Pump Station to the intake control house is 2.3 miles of 300 m.c.m., 5 kv, Parkway Cable laid under-ground. The telephone control cable has an approximate total length of 84,000 feet with 433 poles, ranging from 25 to 75 feet in length. The cable is 6-pair, pulp insulated, 19 gauge, non-coated lead sheath. The transformer bank at the Booster Pump Station has been described under "Booster Pump Station Equipment".
