Kewanna STP - Advanced Wastewater Treatment Plant in Kewanna, Indiana

Kewanna STP is a municipal wastewater treatment facility located at 101 South Toner Street in Kewanna, Indiana, serving a population of 711. The plant provides advanced treatment, reflecting a commitment to high effluent quality standards within the community. The plant's designed capacity is 227.12 megaliters, with an annual discharge volume of 227.13 megaliters, indicating near-capacity operation. As a US facility, it operates under the Clean Water Act, requiring an NPDES permit issued by the Indiana Department of Environmental Management, which sets effluent limits to protect water quality. The treated wastewater is discharged into a local water body that ultimately drains into the Tippecanoe River, a tributary of the Wabash River, which flows to the Ohio River and then the Mississippi River. This connection to the Gulf of Mexico underscores the plant's role in regional water quality and downstream ecosystem health.

The plant discharges into a local stream that feeds the Tippecanoe River, part of the Wabash River basin. This watershed supports diverse aquatic life, including fish species such as bass and catfish, and provides habitat for migratory birds. The advanced treatment helps protect downstream water quality in the Mississippi River system, which ultimately reaches the Gulf of Mexico, reducing nutrient loads that can contribute to hypoxic zones.
