Iroquois Falls Sewage Treatment Plant - Ansonville, Ontario Wastewater Facility

The Iroquois Falls Sewage Treatment Plant is a municipal wastewater facility located in Ansonville, within the town of Iroquois Falls, Ontario, Canada. It serves a population of about 3,613 residents, classifying it as a small-scale treatment plant under Canadian regulatory standards. The plant is situated in the Cochrane District of Northeastern Ontario, an area characterized by boreal forest and cold winters. As a Canadian facility, the plant operates under provincial regulations administered by the Ontario Ministry of the Environment, Conservation and Parks. The plant's designed capacity is 1.00 million cubic meters per day, indicating it is sized to handle the community's wastewater flows. The treated effluent is discharged into a local watercourse that ultimately drains into the Abitibi River system, which flows northward into James Bay. This watershed supports diverse aquatic life and is part of the larger Hudson Bay drainage basin. The plant's operation is critical for protecting downstream water quality in this ecologically sensitive region.

The plant discharges into the Abitibi River watershed, which flows into James Bay, a southern extension of Hudson Bay. This region supports important fish populations, including walleye and northern pike, and provides habitat for migratory waterfowl. The boreal forest ecosystem relies on clean water for its ecological balance, making effective wastewater treatment essential for preserving local biodiversity and downstream water quality.
