Elkhart WWTP discharges into a tributary of the Des Moines River, which flows into the Mississippi River and eventually the Gulf of Mexico. The local watershed is part of the larger Mississippi River Basin, an ecologically significant system that supports diverse fish and wildlife. The plant's secondary treatment helps reduce nutrient loading, which is critical for mitigating hypoxia in the Gulf of Mexico.
