Little Racoon RWD Wastewater Treatment Plant, Montgomery County, Indiana

Little Racoon RWD is a municipal wastewater treatment facility located in Montgomery County, Indiana, serving a population of approximately 1,094 residents. The plant provides secondary treatment, a standard level for small communities in the United States, ensuring that organic matter and suspended solids are substantially reduced before discharge. The plant's designed capacity is 287.69 volume units, with a similar discharge volume, indicating it operates near its design capacity. As a US facility, it 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. These permits set effluent limits to protect water quality. The treated effluent is discharged to a local water body, which ultimately drains into the Wabash River basin, 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 secondary treatment helps maintain water quality in this watershed.

The plant discharges into a local stream that flows into the Wabash River, a major tributary of the Ohio River. The Wabash River basin supports diverse aquatic species and provides habitat for fish and migratory birds. Downstream, the Ohio River joins the Mississippi River, which empties into the Gulf of Mexico, making the plant's effluent part of a large transboundary watershed. Secondary treatment reduces organic pollutants, protecting downstream ecosystems from oxygen depletion.
