Bakersfield WWTP 2: Municipal Wastewater Treatment in Bakersfield, California

Bakersfield WWTP 2 is a municipal wastewater treatment facility located at 1988 East Planz Road in Bakersfield, Kern County, California. It serves a population of about 146,363, placing it in the large agglomeration category. The plant is situated inland, approximately 50 kilometers from the Pacific coast. Under the US Clean Water Act, wastewater treatment plants of this scale are typically required to provide secondary treatment as a minimum standard. The National Pollutant Discharge Elimination System (NPDES) permit program, administered by the California State Water Resources Control Board, governs discharge limits and monitoring requirements. The regulatory framework ensures that effluent quality meets federal and state standards. The plant's treated effluent is discharged into the local watershed, which drains into the Kern River and ultimately reaches the Tulare Lake Basin, an endorheic basin in the San Joaquin Valley. This region is ecologically significant, supporting agricultural irrigation and providing habitat for migratory birds and aquatic species. The plant plays a critical role in protecting water quality in this arid, agriculturally intensive area.

The plant discharges into the Kern River watershed, which flows into the Tulare Lake Basin, a historically significant but now largely dry lakebed in the San Joaquin Valley. This basin is an endorheic system, meaning it does not drain to the ocean, making water quality management crucial for local agriculture and wildlife. The area supports diverse aquatic life and serves as an important stopover for migratory birds along the Pacific Flyway.
