Cannington WPCP Lagoon - Secondary Wastewater Treatment in Brock, Ontario

Cannington WPCP Lagoon is a wastewater treatment facility located in the community of Cannington, part of the Municipality of Brock in Durham Region, Ontario, Canada. The plant serves a population of approximately 2,096 residents and operates under Ontario's regulatory framework for municipal wastewater. The plant provides secondary treatment, which is the standard level required for communities of this size under the Ontario Water Resources Act and the Canada-wide Strategy for the Management of Municipal Wastewater Effluent. Secondary treatment effectively removes organic matter and suspended solids, ensuring the effluent meets provincial water quality objectives. The treated effluent is discharged into local watercourses that ultimately drain into Lake Simcoe, a large inland lake and part of the Great Lakes Basin. Lake Simcoe supports diverse aquatic life and is a vital recreational and ecological resource. The plant plays a key role in protecting the lake's water quality and the downstream environment.

The plant's discharge enters the Lake Simcoe watershed, which drains into Lake Simcoe and then via the Trent-Severn Waterway to Lake Ontario. Lake Simcoe is a large inland lake that supports coldwater fish species such as lake trout and whitefish, and is an important migratory corridor for birds. Protecting its water quality is critical for both ecological health and regional recreation.
