Abstract: The Orange Cove Irrigation District covers about 28,000 Acres in the Central Valley of California. It is supplied from the Friant-Kern Canal. A semi-closed low pressure pipeline system with Harris float valves is used to distribute the water. The portion of the District below the canal has a gravity supply and the portion above has water pumped up in stages. The pipe system and pumps have had increasing maintenance and operation costs. They are being replaced by larger pipe increasing capacity by two thirds and with fever pumps lifting to terminal reservoirs at the upper end of each lift line. Some in-canal storage fluctuation is permitted by the member districts. District costs are being greatly reduced and on-farm benefits from the upgraded schedule are appreciable.
