Stallion Springs CSD WWTF is a municipal wastewater treatment facility located in Stallion Springs, Kern County, California. The plant serves a small community of 561 residents, providing secondary treatment to meet state and federal water quality standards. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater. With a designed capacity of 227.12 megaliters and an annual discharge volume of 189.27 megaliters, the facility operates within its capacity. As a small agglomeration, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the California State Water Resources Control Board. The treated effluent is discharged into local waterways that drain into the San Joaquin Valley watershed. This region is part of the larger Tulare Lake Basin, an endorheic basin that historically supported extensive wetlands and diverse aquatic life. The plant's operations help protect downstream water quality in this ecologically sensitive area.

The plant discharges into the Tulare Lake Basin, an endorheic watershed in the southern San Joaquin Valley. This basin historically contained the largest freshwater lake west of the Mississippi River, now largely dry due to agricultural diversion. The area supports critical habitat for migratory birds and endemic species. Downstream waters eventually flow into the San Joaquin River system, which drains to the Sacramento-San Joaquin Delta and San Francisco Bay, a vital estuarine ecosystem.
