CNC Wastewater Treatment Plant - Chisasibi, Québec, Canada

The CNC Wastewater Treatment Plant is located in Chisasibi, within the Eeyou Istchee Baie-James territory in northern Québec, Canada. It serves a population of approximately 2,098 residents, providing secondary treatment for municipal wastewater. The plant is situated in a remote, subarctic region near the eastern shore of James Bay. As a secondary treatment facility, the plant meets the basic standard for organic matter and suspended solids removal required under Canadian federal and provincial regulations. Secondary treatment typically involves biological processes such as activated sludge or aerated lagoons, which are common in northern communities. The reported discharge volume of 942 cubic meters per day suggests it is sized appropriately for the local population. The plant discharges treated effluent into the local watershed, which ultimately drains into James Bay, a southern extension of Hudson Bay. This coastal environment supports diverse aquatic life, including fish species such as lake sturgeon and brook trout, and provides important habitat for migratory birds. The plant's operation is critical for protecting the sensitive subarctic ecosystem and the traditional lands of the Cree and Inuit peoples.

The CNC Wastewater Treatment Plant discharges into the Chisasibi River system, which flows into James Bay, part of the Hudson Bay watershed. This coastal region is ecologically sensitive, supporting fish populations like lake sturgeon and providing critical stopover habitat for migratory waterfowl along the Atlantic Flyway. The subarctic climate and short growing season make the local environment particularly vulnerable to nutrient loading and contaminants, underscoring the importance of effective wastewater treatment.
