Automation of Booster Pump Stationsby Roger W. Beieler, CH2M Hill, Yakima, WA, USA,
Abstract: Several techniques have been used to automate booster pump stations for irrigation conveyance systems. These pump stations typically must supply pressurized water for a wide range of flow rates, from full flow if all the growers are irrigating, to as low as one percent of full flow if only a few growers are irrigating. Automation and flow-matching by means of: (1) graduation of pumping unit capacity, (2) tanks and level switches, (3) pressure switches, (4) variable discharge pumping units, and (5) recirculating systems are discussed and compared.
