The plant discharges into a local stream that is part of the Spring River watershed, which drains into the Neosho River and then the Arkansas River. This river system supports diverse aquatic life and provides water for agricultural and recreational uses downstream. The plant's secondary treatment helps reduce nutrient loading and organic pollution, contributing to the ecological health of the receiving waters.
