Sherkston Shores WWTP - Port Colborne, Ontario Secondary Treatment Plant

Sherkston Shores WWTP is a municipal wastewater treatment facility located in Port Colborne, Ontario, Canada. It serves a small population of 820 residents in the Sherkston Shores area, part of the Niagara Region. The plant is situated near the northern shore of Lake Erie, one of the Great Lakes. The plant provides secondary treatment, which is the standard biological treatment level required under Canadian federal and provincial regulations for communities of this size. The plant operates under Ontario's Environmental Compliance Approval (ECA) regime, which sets effluent quality standards to protect receiving waters. Treated effluent from the plant discharges into the Lake Erie basin, a vital freshwater ecosystem supporting diverse aquatic life and recreational activities. The plant plays a key role in protecting local water quality and the broader Great Lakes system, which is a critical resource for millions of Canadians and Americans.

The plant discharges into the Lake Erie watershed, the shallowest and most biologically productive of the Great Lakes. Lake Erie supports a rich fishery and is a major source of drinking water. The Niagara Region's coastal wetlands and tributaries provide important habitat for migratory birds and fish species. Protecting water quality here helps prevent algal blooms and maintains ecosystem health.
