Cambria WQCP Wastewater Treatment Plant, Cambria, California

Cambria WQCP is a municipal wastewater treatment facility serving the community of Cambria in San Luis Obispo County, California. With a population served of 6,500, the plant is classified as a small-to-medium agglomeration. Its designed capacity is 1.00 million gallons per day, reflecting the scale of the local service area. The plant operates under the regulatory framework of the US Clean Water Act, administered by the California State Water Resources Control Board and the Central Coast Regional Water Quality Control Board. Facilities of this size are typically required to meet secondary treatment standards, with permits specifying effluent limits for biochemical oxygen demand, total suspended solids, and other parameters. Treated effluent from Cambria WQCP is discharged to the local watershed, which ultimately drains to the Pacific Ocean. The plant's proximity to the coast (within 50 km) means its discharge can affect coastal water quality and marine ecosystems. Proper treatment is essential to protect sensitive habitats along the California coastline.

The plant's discharge enters the local watershed, which flows to the Pacific Ocean via small coastal streams. The California coast supports diverse marine life, including kelp forests, sea otters, and migratory seabirds. Effluent quality must meet stringent state standards to prevent nutrient loading and protect nearshore habitats from eutrophication and pathogen contamination.
