Monteith Correctional Center Wastewater Treatment Plant, Iroquois Falls, Ontario

Monteith Correctional Center Wastewater is a municipal wastewater treatment facility located in Monteith, near Iroquois Falls, Ontario, Canada. The plant serves a small population of 184 people and operates under the regulatory framework of the Ontario Water Resources Act and the Canadian Environmental Protection Act. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant treats an average of 111.00 cubic meters of wastewater per day. Secondary treatment is the standard for small agglomerations in Canada, ensuring compliance with federal and provincial effluent quality standards. The facility is operational and managed as part of the correctional center's infrastructure. The treated effluent is discharged into the local watershed, which ultimately drains into the Abitibi River and then into James Bay, a southern extension of Hudson Bay. This coastal proximity (within 10 km) means the discharge can affect the sensitive estuarine and marine ecosystems of James Bay, which supports diverse aquatic life including fish and migratory birds.

The plant discharges into the Abitibi River system, which flows northward into James Bay, part of the Hudson Bay drainage basin. This coastal region supports ecologically significant habitats, including wetlands and estuaries that are critical for waterfowl and fish species. The secondary treatment level helps mitigate nutrient and pollutant loads, but the proximity to the coast requires careful management to protect downstream marine environments.
