The plant serves a population of approximately 1,100 residents, classifying it as a small-scale treatment facility within the region. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater facilities. With a designed capacity of 529.96 million gallons per year and an actual discharge volume of 423.97 million gallons per year, the plant operates at about 80% capacity.

The treated effluent is discharged into a local water body that ultimately drains into the Ohio River basin. The Ohio River is a major tributary of the Mississippi River, supporting diverse aquatic life and providing drinking water for millions downstream. The plant's location inland and away from coastal areas reduces direct marine impact.

The plant discharges into a receiving water body within the Ohio River watershed, which flows into the Mississippi River and eventually the Gulf of Mexico. The Ohio River supports a variety of fish species and is an important migratory corridor for birds. The plant's secondary treatment helps protect water quality in this ecologically significant river system.
