Western Riverside County Regional Wastewater Authority Treatment Plant

The Western Riverside County Regional Wastewater Authority (WRCWRA) plant is an essential part of the infrastructure in our region, providing sewer treatment services to the community. The plant currently treats 8 million gallons a day of wastewater but will be expanded to 14 million gallons a day by 2017. Water is treated at a tertiary level (one of the highest treatment levels) and is currently discharged into the Santa Ana River after treatment.

In addition to the expansion, we're working diligently on this project using cutting-edge technologies to minimize odors and increase the capacity of intake into the facility to continue to be a local source of water reliability now and in the future.

Besides the health and welfare benefits the community receives, the facility will soon produce recycled water for local uses on parks, nurseries and other outdoor spaces while reducing the region’s dependence on imported water.

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