The plant's discharge enters local waterways within the Tippecanoe River watershed, which flows into the Wabash River, a major tributary of the Ohio River. This river system supports diverse fish populations and provides habitat for migratory birds. The region's agricultural landscape means that nutrient management from wastewater is important to prevent downstream eutrophication.
