Jasonville WWTP: Municipal Wastewater Treatment in Jasonville, Indiana

Jasonville WWTP is a municipal wastewater treatment facility located on SR 59 in Jasonville, Greene County, Indiana. The plant serves a population of about 2,490 people, placing it in the small community category for U.S. wastewater infrastructure. As an inland facility in the Midwestern United States, it manages wastewater from residential sources in a rural setting. Under the U.S. Clean Water Act, municipal wastewater treatment plants serving populations under 10,000 are typically required to provide secondary treatment, which includes biological processes to remove organic matter and suspended solids. The plant's discharge is regulated through a National Pollutant Discharge Elimination System (NPDES) permit issued by the Indiana Department of Environmental Management, ensuring compliance with water quality standards. The treated effluent from Jasonville WWTP is discharged into a local receiving water body, which ultimately drains into the Wabash River basin. The Wabash River flows southwest through Indiana and joins the Ohio River, which then empties into the Mississippi River and eventually the Gulf of Mexico. The plant plays a key role in protecting local streams and downstream aquatic ecosystems from nutrient pollution and pathogens.

The plant discharges into a tributary of the Wabash River, which flows through agricultural and forested areas of southern Indiana. The Wabash River supports diverse aquatic life, including fish species such as bass and catfish, and provides habitat for freshwater mussels. Downstream, the river joins the Ohio River, a major tributary of the Mississippi River, which drains into the Gulf of Mexico. The plant's treatment helps reduce nutrient loads that could contribute to hypoxia in the Gulf.
