Water Pollution Control Centre, Sarnia, Ontario - Municipal Wastewater Treatment

The Water Pollution Control Centre is a municipal wastewater treatment facility located on Imperial Avenue in Sarnia, Ontario, Canada. It serves a population of about 52,198 residents in the Lambton County area. The plant is operational and plays a key role in managing wastewater for the community. As a Canadian facility, the plant operates under federal and provincial regulations, including the Canadian Environmental Protection Act and Ontario's Clean Water Act. For a medium-sized agglomeration serving over 50,000 people, secondary treatment is typically required to meet effluent quality standards. The plant's designed capacity is 1.00 million cubic meters per day, indicating it is sized to handle the community's wastewater flows. The treated effluent from the plant is discharged into the St. Clair River, which flows south into Lake St. Clair and then into the Detroit River, ultimately reaching Lake Erie. This water body supports diverse aquatic life and is an important migratory corridor for fish species. The plant's operations help protect the downstream ecosystem and the Great Lakes water quality.

The plant discharges into the St. Clair River, a major connecting channel between Lake Huron and Lake St. Clair. The river supports a variety of fish species and is part of the Great Lakes Basin, a globally significant freshwater ecosystem. Downstream, the water flows through Lake St. Clair and the Detroit River into Lake Erie, which is ecologically sensitive due to nutrient loading and algal blooms. The plant's treatment performance is critical to maintaining water quality in this interconnected system.
