The Western Riverside County Regional Wastewater Authority Plant

was built in 1998 and currently treats 8 million gallons per day of wastewater. When the plant was first built, the area around the facility was comprised of dairy farms, a green waste composting facility and the Santa Ana River; at the time it was built for the specifications required for the area. With the successful development in Eastvale the dairies and composting facilities sold, and homes have been built in their place. The plant is currently undergoing an expansion, which will include enhancements to mitigate odors. The expansion is anticipated to be complete in late 2017.


WRCRWA is a joint powers authority consisting of the cities of Norco and Corona, Jurupa Community Services District, Home Gardens Sanitary District and Western.
