Greenway Pollution Control Centre | London, Ontario Wastewater Treatment Plant

Greenway Pollution Control Centre is a major wastewater treatment facility located in London, Ontario, Canada. Serving a population of approximately 255,739, it is one of the key municipal plants in the region, supporting the city's residential and industrial wastewater needs under Ontario's regulatory framework. The plant operates under Ontario's Environmental Protection Act and the Canada Water Act, which set stringent standards for effluent quality. For a facility of this scale, advanced treatment is typically required to protect sensitive receiving waters. The plant's designed capacity is 1.00 (likely in million cubic meters per year or similar unit), indicating a large-scale operation. Treated effluent from the plant is discharged into the Thames River, which flows southwest through Southwestern Ontario and empties into Lake St. Clair. From there, water enters the Detroit River and then Lake Erie, part of the Great Lakes system. The Thames River supports diverse aquatic life and is an important migratory corridor for fish species. The plant's performance is critical to maintaining water quality in this ecologically significant watershed.

The plant discharges into the Thames River, which flows through London and joins the North Thames River before reaching Lake St. Clair. This water body is part of the Great Lakes Basin, one of the largest freshwater systems in the world. The Thames River supports a variety of fish species, including sport fish, and provides habitat for migratory birds. Protecting water quality in this watershed is essential for downstream ecosystems and drinking water sources.
