The area drains into the Red River basin, which flows north into Lake Winnipeg, a large lake with significant ecological importance for migratory birds and fish populations.

The plant is situated in the Red River basin, which ultimately drains into Lake Winnipeg. Lake Winnipeg is a large, shallow lake that supports diverse aquatic life and is a critical habitat for fish species such as walleye and lake sturgeon. The watershed also provides important migratory corridors for waterfowl. Proper treatment of wastewater is essential to prevent nutrient loading, which can contribute to algal blooms in the lake.
