Treatment Plants

WRCRWAWRCRWA Plant & Solar Power System

The Western Riverside County Regional Wastewater Authority (WRCRWA) plant, which is governed via a Joint Powers Authority and managed by Western, is a tertiary treatment facility capable of providing recycled water for reuse or for discharge through an outfall to the Santa Ana River. It was brought online in 1998. It has a design capacity for 8 million gallons per day (MGD) and will soon be expanded to 13.25 MGD.

In 2006, Western took ownership of the former March Air Reserve Base wastewater system. Western recently completed its Western Water Recycling Facility expansion project, which will bring a much-needed local, secure source of recycled water for the region.

The approximately $50 million expansion project is the largest, single construction project Western has undertaken in its 50-plus year history. The expansion has increased the facility’s capacity to 3 million gallons of wastewater treated per day and upgraded it to tertiary treatment, the highest level of treatment. Prior to the expansion, the facility treated 1 million gallons of water a day at secondary treatment levels.

That water continues to be provided to the General Archie Old Golf Course and the Riverside National Cemetery for irrigation purposes. Now with tertiary treatment, Western is able to provide recycled water to additional nonpotable water use customers.

As part of its Strategic Plan, Western is committed to finding local sources of water for customers to ease their use on costly and less reliable imported water supplies. Coupled with Southern California’s growing population and demand for water, it’s essential for Western to continue to diversify water supplies.
