Corcoran WWTF - Municipal Wastewater Treatment in Corcoran, California

Corcoran WWTF is a municipal wastewater treatment facility located in Corcoran, Kings County, California. It serves a population of about 12,721 people, making it a medium-sized plant for the region. The plant is situated in California's Central Valley, an area dominated by agriculture and characterized by a semi-arid climate. As a US facility, Corcoran WWTF operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the California State Water Resources Control Board. For a plant serving this population size, secondary treatment is typically required, and the plant likely employs conventional treatment processes to meet state and federal standards. The plant's treated effluent is discharged into the Tulare Lake Basin, an endorheic basin that historically contained Tulare Lake, once the largest freshwater lake west of the Mississippi. Today, the basin is primarily used for agricultural irrigation and groundwater recharge. The discharge supports local water supplies and contributes to the region's hydrologic balance, though careful management is needed to prevent nutrient loading and protect groundwater quality.

Corcoran WWTF discharges into the Tulare Lake Basin, an endorheic watershed in California's Central Valley. The basin has no natural outlet to the ocean, so treated wastewater is used for irrigation or percolates into groundwater. This closed system requires careful nutrient management to prevent accumulation of salts and contaminants, which could impact agricultural productivity and local ecosystems. The region supports diverse wildlife, including migratory birds that rely on remaining wetlands and agricultural habitats.
