TFN Sewage Treatment Plant - Secondary Wastewater Treatment in Metro Vancouver, British Columbia

The TFN Sewage Treatment Plant is located on Tsawwassen Drive in sc̓əwaθən (Tsawwassen), within the Metro Vancouver Regional District of British Columbia, Canada. This small-scale facility serves a population of 668 and operates under secondary treatment standards, reflecting its role in managing local wastewater from the community. The plant provides secondary treatment, which involves biological processes to reduce organic matter and suspended solids. With a daily discharge volume of 300 cubic meters, the facility meets the regulatory requirements for smaller agglomerations in Canada. Canadian wastewater treatment is governed by the Wastewater Systems Effluent Regulations (WSER) under the Fisheries Act, which set national effluent quality standards for all systems serving over 100 people. The treated effluent is discharged into the local environment near the Strait of Georgia, a major coastal water body in the Salish Sea. This area supports diverse marine life, including salmon, herring, and migratory birds. The plant's coastal location necessitates careful management to protect the sensitive marine ecosystem and recreational waters of the region.

The plant discharges into the Strait of Georgia, part of the Salish Sea, which ultimately connects to the Pacific Ocean. This coastal environment supports critical habitats for salmon, orcas, and seabirds. The proximity to the coast means that treated effluent must meet stringent standards to prevent nutrient enrichment and protect marine biodiversity. The area is also important for First Nations cultural and subsistence practices.
