San Diego County Sanitation District (District)
The District provides sewer service to nearly 36,000 customers in the unincorporated areas of the county. Wastewater from the communities of Alpine, East Otay Mesa, Lakeside, Spring Valley, and Winter Gardens, are conveyed through a network of collector pipes, trunk lines, and pump stations to the City of San Diego’s Point Loma Treatment Plant for treatment and disposal. Wastewater from the rural communities of Julian, Pine Valley, and Campo is conveyed to nearby District-operated wastewater treatment plants for treatment and disposal.
The District sanitary sewer system is comprised of approximately 432 miles of sewer lines, 8,200 manholes, 8 pump stations, several pressurized force mains, and 3 wastewater treatment plants. The sewer lines are routinely cleaned, inspected using Closed-Circuit TV equipment, and repaired and rehabilitated as needed. There are also routine maintenance schedules for the manholes, pump stations, and treatment plant components.
