Port Renfrew Wastewater Treatment Plant - Secondary Treatment in British Columbia

The Port Renfrew Wastewater Treatment Plant is a small municipal facility located on Tsonoqua Drive in Port Renfrew, within the Juan de Fuca Electoral Area of British Columbia's Capital Regional District. Serving a population of 122, it operates as a secondary treatment plant, meeting Canadian federal and provincial wastewater standards for small communities. As a secondary treatment facility, the plant uses biological processes to reduce organic matter and suspended solids before discharge. The plant's daily discharge volume is 55.00 cubic meters, reflecting the small population served. Canadian wastewater regulations under the Wastewater Systems Effluent Regulations (WSER) require secondary treatment or equivalent for facilities of this scale, ensuring protection of receiving waters. The plant is located within 10 km of the Pacific Ocean, discharging treated effluent into the coastal environment near Port Renfrew. The receiving waters ultimately flow into the Strait of Juan de Fuca, a critical marine corridor connecting the Pacific Ocean to the Salish Sea. This area supports diverse marine life, including salmon, orcas, and seabirds, making proper treatment essential for ecosystem health.

Treated effluent from the Port Renfrew plant enters the coastal waters of the Strait of Juan de Fuca, a major marine channel linking the Pacific Ocean to the Salish Sea. This region supports ecologically sensitive habitats, including kelp forests and eelgrass beds, which provide nursery grounds for fish and invertebrates. The area is also an important migratory route for Pacific salmon and marine mammals, requiring careful management of nutrient and pathogen loads from wastewater discharges.
