Overview
Village of Port Clements Sewage Lagoon is a secondary treatment plant serving 377 people in British Columbia, Canada. It discharges treated wastewater near the coast of Haida Gwaii.
The Village of Port Clements Sewage Lagoon is a municipal wastewater treatment facility located on Industrial Park Road in Port Clements, British Columbia, on Graham Island in the Haida Gwaii archipelago. The plant serves a small population of 377 residents and operates under the regulatory framework of the Canadian Council of Ministers of the Environment (CCME) guidelines and provincial regulations from the British Columbia Ministry of Environment and Climate Change Strategy. The facility provides secondary treatment, which is appropriate for its small scale. As a lagoon-based system, it relies on natural biological processes to treat wastewater. The plant discharges approximately 188.90 megaliters of treated effluent annually. Canadian wastewater facilities of this size typically operate under provincial permits that set effluent quality standards for parameters such as biochemical oxygen demand and total suspended solids. The plant's discharge enters the local watershed on Haida Gwaii, an ecologically sensitive archipelago known for its temperate rainforests and diverse marine life. The treated effluent ultimately reaches the Pacific Ocean via nearby coastal waters. The region supports important salmon runs and marine habitats, making proper wastewater treatment critical for protecting downstream ecosystems.
Environmental context
The plant discharges into the coastal waters of Haida Gwaii, an archipelago off the coast of British Columbia. The receiving environment includes nearshore marine habitats that support salmon, herring, and other commercially and ecologically important species. The area is part of the larger Pacific Ocean basin and is influenced by the nutrient-rich waters of the Alaska Current. Proper treatment helps protect these sensitive marine ecosystems from nutrient loading and pathogens.
