Woodlake WWTF - Municipal Wastewater Treatment in Woodlake, California

Woodlake Wastewater Treatment Facility (WWTF) is a municipal treatment plant located on South Valencia Boulevard in Woodlake, California, within Tulare County. The plant serves a population of about 7,100 people, placing it in the small-to-medium agglomeration category for U.S. wastewater systems. As a U.S. facility, Woodlake WWTF operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The plant's treated effluent is discharged into the local watershed, which drains into the Kaweah River and then into the Tulare Lake Basin, an endorheic basin in California's Central Valley. This region supports agricultural irrigation and provides habitat for migratory birds and aquatic species, making water quality management critical for both human use and ecological health.

Woodlake WWTF discharges into the Kaweah River watershed, which flows into the Tulare Lake Basin, a historically significant wetland area in California's Central Valley. The basin, though largely converted to agriculture, still supports seasonal wetlands and provides critical habitat for waterfowl and shorebirds along the Pacific Flyway. Protecting water quality in this endorheic basin is essential to prevent salt and nutrient buildup that could harm both agricultural productivity and remaining natural habitats.
