Orange Cove Wastewater Treatment Facility (WWTF) - Fresno County, California

Orange Cove Wastewater Treatment Facility (WWTF) is a municipal treatment plant located in Fresno County, California, serving a population of about 7,700. The facility is situated inland, more than 50 kilometers from the coast, and operates under the regulatory oversight of the US Clean Water Act. As a plant serving a small community, Orange Cove WWTF is subject to National Pollutant Discharge Elimination System (NPDES) permitting requirements. Treatment processes for facilities of this scale typically include primary and secondary treatment stages to meet effluent quality standards. Regulatory compliance is enforced through state-issued permits. The treated effluent from Orange Cove WWTF is discharged into local waterways that ultimately drain into the San Joaquin River basin. This river system supports agricultural irrigation and provides habitat for diverse aquatic species. The plant's operations are important for protecting downstream water quality in the Central Valley region.

Orange Cove WWTF discharges into tributaries of the San Joaquin River, which flows through California's Central Valley before reaching the Sacramento-San Joaquin Delta and San Francisco Bay. The river system supports critical agricultural water supplies and provides habitat for fish species such as Chinook salmon and steelhead trout. Effluent quality management is essential to prevent nutrient loading and protect downstream ecosystems.
