The Western Riverside County Regional Wastewater Authority Treatment Plant
First built in 1998 the Western Riverside County Regional Wastewater Authority (WRCRWA) Plant treats 14 million gallons per day (MGD) of wastewater. Following a recent expansion of the WRCRWA Treatment Plant, capacity to treat wastewater increased from 8 MGD to the now 14 MGD. When the WRCRWA Treatment Plant was originally built, the area around the facility was comprised of dairy farms, a green waste composting facility, and the Santa Ana River; at the time, the WRCRWA Treatment Plant was built for the specifications required for the area. With the successful development in Eastvale, the dairies and composting facilities sold, and homes were built in their place.
WRCRWA is a joint powers authority consisting of the cities of Norco and Corona, Jurupa Community Services District, Home Gardens Sanitary District and Western Municipal Water District.
