The Santa Rosa Water Reclamation Facility (SRWRF) is responsible for collecting, treating, and safely disposing of, or recycling wastewater and its residuals for residents and business in the Temecula, Murrieta, and Wildomar communities. The plant is located in the City of Murrieta.

The Authority's infrastructure includes the SRWRF, as well as any manhole, gravity main, force main, or lift station which conveys wastewater flows from two or more of the following Districts:

The system handles flows from the Cities of Temecula, Wildomar, and Murrieta. This system of pipes is referred to as the “collection system.” The collection system consists of 80 miles of pipes ranging from eight inches in diameter up to 24 inches in diameter. Most of the system flows by gravity to lift stations that raise the water to a higher level so that it can continue its journey to the reclamation facility. The system contains three lift stations.



Wastewater flows originating in the Authority's service area are treated at the Santa Rosa Water Reclamation Facility in Murrieta. The treatment plant was constructed in 1989 and is a sequencing batch reactor treatment facility with a secondary treatment capacity of 5 million gallons per day(mgd) and a tertiary treatment capacity of 5 mgd.

The SRWRF 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 plant's reclaimed water customer's use virtually all of the treated water. On average, the plant treats approximately 1 billion gallons of wastewater annually.
