The Santa Rosa Regional Resources Authority (SRRRA) is a Joint Powers Authority formed by Elsinore Valley Municipal Water District (Elsinore), Rancho California Water District (Rancho), and Western Municipal Water District (Western) on November 12, 2015. The SRRRA highlights long-term sound planning and investment in wastewater infrastructure for the southwestern Riverside County region. The Authority is responsible for the collection, transmission, treatment and disposal of wastewater from its member agencies relating to flows to the Santa Rosa Water Reclamation Facility (SRWRF) in Murrieta, California. This responsibility includes the acquisition, construction, and financing of capital projects for the SRWRF.
The Authority’s service area encompasses all three districts but focuses on those areas delivering flows to the SRWRF, which is the SRRRA's sole treatment plant.
The SRRRA is located in the southwestern part of Riverside County, which includes portions of the Cities of Temecula and Murrieta, and other contiguous land in the unincorporated territory of the County of Riverside.
