The plant discharges into tributaries of the River Raisin, which flows into Lake Erie, a key component of the Great Lakes ecosystem. Lake Erie supports diverse fish populations and is a major source of drinking water. The watershed is sensitive to nutrient pollution, making effective wastewater treatment critical for preventing algal blooms and maintaining water quality.
