This waterway supports diverse aquatic life and is used for recreation and drinking water downstream.

The plant's discharge enters the White River basin, a major tributary of the Wabash River, which flows to the Ohio River and ultimately the Mississippi River. The watershed supports diverse aquatic species and is an important resource for regional water supply and recreation. Nutrient loading from wastewater can impact downstream water quality, making treatment standards critical for ecological health.
