Crawfordsville WWTP | Municipal Wastewater Treatment in Crawfordsville, Indiana

Crawfordsville WWTP is a municipal wastewater treatment facility located in Crawfordsville, Montgomery County, Indiana. Serving a population of about 19,684, the plant is part of the city's essential infrastructure for managing domestic and industrial wastewater. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Indiana Department of Environmental Management. For a community of this size, secondary treatment is typically required to meet effluent limits before discharge. The treated effluent is discharged into a receiving water body that flows into the Wabash River, a major tributary of the Ohio River. The Wabash River supports diverse aquatic life and is an important ecological corridor in the Midwest.

The plant's discharge enters a local stream that drains into the Wabash River, which flows southwest to the Ohio River and ultimately to the Mississippi River and Gulf of Mexico. The Wabash River watershed supports diverse fish populations and provides habitat for migratory birds. Protecting water quality in this basin is critical for downstream ecosystems and recreational uses.
