Overview
Mattagami Water Pollution Control Plan serves Timmins, Ontario, treating wastewater for approximately 33,426 residents. The plant is operational and discharges into the local watershed within the Great Lakes Basin.
The Mattagami Water Pollution Control Plan is a municipal wastewater treatment facility located in Timmins, Ontario, Canada. Serving a population of around 33,426, the plant is a key component of the region's sanitation infrastructure, operating under Ontario's regulatory framework for wastewater management. As a medium-sized agglomeration, the plant is expected to meet treatment standards set by the Ontario Ministry of the Environment, Conservation and Parks, which align with the Canada-wide Strategy for the Management of Municipal Wastewater Effluent. Facilities of this scale typically employ secondary treatment to reduce organic matter and suspended solids before discharge. The plant's treated effluent is released into the local watershed, which drains into the Mattagami River, a tributary of the Moose River system that flows into James Bay. This discharge contributes to the overall water quality of the Great Lakes Basin, supporting aquatic habitats and downstream ecosystems in the boreal forest region.
Environmental context
The plant discharges into the Mattagami River, which flows northward through the boreal forest to join the Moose River and ultimately empty into James Bay, a southern extension of Hudson Bay. This watershed supports diverse fish populations, including walleye and northern pike, and provides critical habitat for migratory waterfowl. The region's cold climate and seasonal ice cover influence treatment plant operations and effluent dilution dynamics.
