It serves a small population of 300 residents and is part of the region's water infrastructure in East Tennessee. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater. It has a designed capacity of 49.21 million gallons per day and currently discharges 34.07 million gallons per day. As a small facility, it is subject to EPA NPDES permitting through the Tennessee Department of Environment and Conservation. The treated effluent is discharged into local waterways that ultimately drain into the French Broad River and then the Tennessee River system, which flows to the Mississippi River and the Gulf of Mexico. The plant plays a role in protecting water quality in the Tennessee Valley watershed.

The plant discharges into the Tennessee River basin, which flows through the Appalachian region and supports diverse aquatic life. The downstream waters include the French Broad River and the Tennessee River, which are important for recreation, drinking water, and habitat for species such as mussels and fish. The plant's secondary treatment helps reduce nutrient and organic loads to these sensitive waterways.
