Warm Springs Rehab WWTF - Secondary Treatment Plant in Los Angeles County, California

Warm Springs Rehab WWTF is a wastewater treatment facility located in Los Angeles County, California, United States. It serves a small population of 264 people, reflecting its role as a local-scale treatment plant within the broader Los Angeles County infrastructure. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal wastewater before discharge. With a designed capacity of 227.12 volume units and an average daily discharge of 151.42, the facility operates below its capacity, indicating room for handling additional flow. As a U.S. plant, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the California State Water Resources Control Board, ensuring compliance with water quality standards. The treated effluent is discharged into the local watershed, which ultimately drains into the Pacific Ocean via the Santa Clara River or Los Angeles River systems. The plant's inland location, more than 50 km from the coast, reduces direct marine impact, but its discharge contributes to the health of regional water bodies and downstream ecosystems.

The plant discharges into a local watercourse within the Los Angeles River or Santa Clara River watershed, both of which flow into the Pacific Ocean. These rivers support diverse aquatic life and are important for regional water quality. The inland location reduces direct coastal impact, but the discharge still affects downstream habitats and water availability in a semi-arid climate.
