Sutton WPCP Wastewater Treatment Plant, Sutton, Ontario

Sutton WPCP is a municipal wastewater treatment facility located in Sutton, Ontario, within the York Region of the Golden Horseshoe. The plant serves a population of approximately 3,463 residents and is situated near the shores of Lake Simcoe, a major inland lake in southern Ontario. The plant operates under Ontario's regulatory framework, which includes the Ontario Water Resources Act and the Environmental Protection Act. For a facility of this scale, secondary treatment is typically required to meet provincial effluent standards. The designed capacity of 1.00 million liters per day indicates a small-scale plant suited to the local community's needs. The treated effluent from Sutton WPCP is discharged into the Lake Simcoe watershed, which ultimately drains into the Great Lakes system via the Trent-Severn Waterway. Lake Simcoe supports diverse aquatic life, including cold-water fish species such as lake trout and whitefish, and is an important recreational and ecological resource in the region.

Sutton WPCP discharges into the Lake Simcoe watershed, which flows through the Trent-Severn Waterway into Lake Ontario, part of the Great Lakes system. Lake Simcoe is a large inland lake that supports a sensitive cold-water fishery and is subject to nutrient management efforts to control algal blooms. The plant's location within 50 km of the coast (Lake Simcoe) means its effluent quality is critical to maintaining the lake's ecological health.
