Serving a population of 281, this plant is a small-scale operation that plays a vital role in managing the community's wastewater. The plant is situated in a rural area of the Midwestern United States, where it supports local sanitation needs. The facility employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 113.56 volume units and a corresponding discharge volume, the plant operates efficiently for its scale. Under the U.S. Clean Water Act, such facilities are regulated through the National Pollutant Discharge Elimination System (NPDES) permit program, which sets effluent limits to protect water quality. The treated effluent is discharged into nearby streams that drain into the White River watershed, ultimately reaching the Mississippi River and the Gulf of Mexico. This downstream connection underscores the plant's role in maintaining the ecological health of regional water bodies, supporting aquatic life and recreational uses.

The plant discharges into local tributaries of the White River, which flows into the Wabash River and then the Mississippi River, eventually reaching the Gulf of Mexico. This watershed supports diverse aquatic species and provides habitat for migratory birds. The advanced treatment helps minimize nutrient loading, protecting downstream water quality in a region where agriculture is prevalent.
