Point Loma WWTF is a key wastewater treatment facility located in San Diego, California, serving a population of over 2 million. As one of the largest treatment plants in the region, it plays a critical role in managing municipal wastewater for the San Diego metropolitan area. The plant operates under the regulatory framework of the US Clean Water Act, which requires NPDES permits for discharges to surface waters. For a facility of this scale, advanced primary treatment is typically employed, with secondary treatment requirements potentially waived under a Section 301(h) modified permit due to the deep ocean outfall.
