Wastewater Treatment

About Wastewater Treatment

Wastewater flows originating in the District service area are treated at the Santa Rosa Water Reclamation Facility in Murrieta. The treatment plant was constructed in 1989 and has the capacity to treat five million gallons of wastewater per day.

The plant uses a biological treatment process followed by chemical clarification, filtration and disinfection to prepare the water for reuse. Laboratory tests are conducted daily to ensure that the water meets the State's standards for reclaimed water. The District's reclaimed water customer's use virtually all of the treated water. In 2011, more than one billion gallons of water were treated and reused.

The Water Environment Federation provides a number of resources for the public to learn more about water reclamation.
