The plant discharges into a receiving water body within the Lake Superior drainage basin, likely the Montreal River or a tributary. This watershed flows northward into Lake Superior, a critical freshwater resource supporting fisheries and recreation. The region's cold-water streams are sensitive to nutrient loading, making secondary treatment important for maintaining water quality.
