Palmdale Water Reclamation Plant

The Palmdale Water Reclamation Plant (WRP) is located at 39300 30th Street East in the City of Palmdale. The plant currently occupies 286 acres east of the Antelope Valley (14) Freeway. It was placed in operation in September 1953 and had a capacity of 0.75 million gallons per day.


The Palmdale WRP is a tertiary treatment plant with solids processing facilities. The plant provides primary, secondary, and tertiary treatment for a design capacity of 12 million gallons of wastewater per day (see flow diagram below). The plant serves a population of approximately 150,000 people. Effluent is reused for irrigation of trees and fodder crops on City of Los Angeles Department of Airports' property and also for parks in the city of Palmdale. The Palmdale WRP processes all wastewater solids generated within its service area. The wastewater solids are anaerobically digested, stored, and then dewatered using centrifuges. The dewatered cake, or biosolids, is hauled away for agricultural land application.
