Efficient Deep Well Pumping

Efficient Deep Well Pumping

The accompanying illustration shows a deep well pumping, plant at Redlands, Cal. The pump houses are of reinforced concrete and the towers arc provided to cover the derricks used in pulling the pump rods. The wells, being in sand and gravel formation, are located some distance apart. This, necessitates the construction of several buildings to cover the different pumps. Each pump is a triplex deep well type, with a capacity of 900 gallons per minute. They have been in use since their installation and have been very efficient. The water lift is about 140 feet and the depth of the well varies from 250 to 700 feet. The total capacity of the plant is 7,650 gallons per minute. It is held that the deep well triplex pumps operate at about the same efficiency as the single acting triplex booster pumps, which are also used to raise a portion of the water to the higher levels of the city. This is according to the reports received from City Engineer George S. Hinckley.
