Perris Valley Regional WRF - Lake Elsinore, California Wastewater Treatment Plant

Perris Valley Regional WRF is a wastewater treatment facility located in Lake Elsinore, California, serving a population of approximately 109,315. The plant is situated in Riverside County and is part of the regional wastewater infrastructure for the area. As a large agglomeration serving over 100,000 people, the plant is expected to provide at least secondary treatment under the US Clean Water Act. The facility operates under the National Pollutant Discharge Elimination System (NPDES) permit program, which regulates discharges to surface waters. The designed capacity is reported as 1.00 (likely in million gallons per day or similar unit), indicating a substantial treatment capability. The plant's treated effluent is discharged to local water bodies within the Santa Ana River watershed, which ultimately drains to the Pacific Ocean. The facility plays a key role in protecting downstream water quality and supporting aquatic ecosystems in the region.

The plant discharges into the Santa Ana River watershed, which flows through Southern California before reaching the Pacific Ocean near Huntington Beach. This region supports diverse aquatic life and is an important migratory corridor for birds. The downstream environment includes sensitive coastal habitats that benefit from effective wastewater treatment.
