Millbrook Wastewater Treatment Plant | Cavan-Monaghan, Ontario, Canada

Millbrook Wastewater Treatment Plant is located in the community of Millbrook within Cavan-Monaghan, Peterborough County, Ontario, Canada. The plant serves a small population of 1,568 residents and operates under secondary treatment standards, which is typical for smaller communities in the province. The plant's treatment process involves secondary treatment, which includes biological processes to reduce organic matter and suspended solids. The plant's discharge volume of 704.00 cubic meters per day indicates its operational scale. In Ontario, wastewater treatment plants are regulated under the Ontario Water Resources Act and the Environmental Protection Act, with permits issued by the Ministry of the Environment, Conservation and Parks. The treated effluent is discharged into a local watercourse that eventually drains into the Lake Ontario basin. This watershed supports diverse aquatic life and is part of the larger Great Lakes ecosystem, which is ecologically significant for both Canada and the United States. The plant's location more than 10 km from the coast reduces direct marine impact.

The plant discharges into a local stream that flows into the Trent-Severn Waterway system, which ultimately drains into Lake Ontario. Lake Ontario is the easternmost Great Lake and supports a variety of fish species, including lake trout and salmon, and serves as a critical water source for millions. The watershed is ecologically sensitive, with wetlands and forests that provide habitat for migratory birds and other wildlife.
