HOLTVILLE WWTF - Wastewater Treatment Plant in Imperial County, California

HOLTVILLE WWTF is a municipal wastewater treatment facility located in Imperial County, California, serving a population of approximately 5,240 residents. The plant is situated inland, over 50 kilometers from the Pacific coast, and operates within the regulatory framework of the United States Clean Water Act. As a facility serving a small population, the plant is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the California State Water Resources Control Board. Plants of this scale typically employ secondary treatment or equivalent technologies to meet effluent standards. The treated wastewater from HOLTVILLE WWTF is discharged into the local watershed, which ultimately drains to the Salton Sea, a large saline lake in Southern California. The Salton Sea is an ecologically sensitive area that supports diverse bird populations and is a critical stopover along the Pacific Flyway migratory route.

The plant's discharge contributes to the watershed that flows into the Salton Sea, a terminal saline lake in the Colorado Desert. The Salton Sea is an important habitat for migratory birds and supports a unique aquatic ecosystem. The region faces challenges from agricultural runoff and increasing salinity, making water quality management critical for downstream environmental health.
