The Environmental Programs team is responsible for implementing the Pretreatment Program and FOG Program.

The City of San Luis Obispo’s Pretreatment Program was established in 1983 to provide protection to the Water Resource Recovery Facility (WRRF) and the sewer collection system by controlling the discharge of non-domestic wastes into the City’s sewer system.  The program is mandated by the Environmental Protection Agency and the State Water Resources Control Board.

The function of the program is to protect the WRRF from discharges that could upset or inhibit the plant’s processes, or pass through the process untreated and then be discharged into San Luis Creek. An illicit discharge to the WRRF can also result in a reduction of waste treatment, possibly contaminating biosolids or recycled water, resulting in expensive handling and disposal costs or degradation of the creek’s environment.
