Rancho Del Campo WWTF - San Diego, California Wastewater Treatment Plant

Rancho Del Campo WWTF is a municipal wastewater treatment facility located in the Kearny Mesa area of San Diego, California. The plant serves a small population of 1,585 residents and operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal plants discharging to surface waters. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 1,173.47 megaliters and an annual discharge volume of 492.10 megaliters, the facility operates well below its capacity. As a coastal plant within 10 km of the Pacific Ocean, it must meet stringent effluent quality standards to protect marine ecosystems. The treated wastewater from Rancho Del Campo WWTF ultimately discharges into the Pacific Ocean via the San Diego region's drainage system. The coastal waters off San Diego support diverse marine life, including kelp forests and fish populations, and are important for recreation and tourism. The plant's secondary treatment helps reduce nutrient loading and protect water quality in this sensitive coastal environment.

The plant discharges treated wastewater into the San Diego coastal watershed, which drains into the Pacific Ocean. The coastal waters off San Diego are ecologically sensitive, supporting kelp forests, fish populations, and migratory species. Secondary treatment reduces organic pollutants and nutrients, helping to protect marine habitats and water quality in the region.
