Julian Water Pollution Control Fac - Wastewater Treatment in Julian, California

Julian Water Pollution Control Fac is a municipal wastewater treatment plant located in Julian, San Diego County, California. It serves a small population of 528 residents, reflecting the rural character of this mountain community in the Cleveland National Forest area. The plant provides secondary treatment, the standard required by the US Clean Water Act for municipal facilities. With a designed capacity of 151.42 units and a current discharge volume of 75.71 units, the plant operates well within its capacity. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the California State Water Resources Control Board, ensuring compliance with water quality standards. The treated effluent is discharged into local waterways that drain into the San Diego River watershed, ultimately reaching the Pacific Ocean. The plant plays a key role in protecting downstream aquatic habitats and the regional water quality in San Diego County's sensitive semi-arid environment.

The plant discharges into tributaries of the San Diego River, which flows through the Cleveland National Forest and into the Pacific Ocean at San Diego Bay. This watershed supports diverse aquatic life, including endangered species such as the arroyo toad and southwestern willow flycatcher. The region's Mediterranean climate with seasonal droughts makes water quality management critical for maintaining ecosystem health and downstream water supplies.
