Churubusco WWTP: Advanced Wastewater Treatment in Churubusco, Indiana

Churubusco WWTP is a municipal wastewater treatment facility located on Millstone Road in Churubusco, Whitley County, Indiana. The plant serves a population of approximately 1,819 residents, classifying it as a small community facility in the Midwestern United States. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the US Clean Water Act. With a designed capacity of 946.35 cubic meters per day and a similar discharge volume, the facility operates efficiently for its scale. As a US-based plant, it is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Indiana Department of Environmental Management. The treated effluent is discharged into local waterways that drain into the Upper Wabash River basin, ultimately reaching the Wabash River and then the Ohio River. The plant plays a key role in protecting downstream aquatic ecosystems from nutrient pollution and pathogens, supporting water quality in the region.

The plant discharges into tributaries of the Upper Wabash River basin, which flows into the Wabash River, a major tributary of the Ohio River. The Wabash River supports diverse aquatic life, including fish species such as bass and catfish, and provides habitat for freshwater mussels. The advanced treatment helps reduce nutrient loads that could otherwise contribute to algal blooms in downstream waters.
