The plant serves a small population of 783 residents and operates with advanced treatment capabilities, ensuring high-quality effluent before discharge. The plant's advanced treatment level exceeds the secondary treatment standard typically required by the US Clean Water Act for facilities of this scale. With a designed capacity of 575.38 units and a discharge volume of 507.25 units, the plant operates below its capacity, indicating effective management of current loads. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River basin. This region is part of the Upper Mississippi River watershed, which supports diverse aquatic ecosystems and provides drinking water for millions downstream. The plant's advanced treatment helps protect these sensitive water resources.

The plant discharges into tributaries of the Upper Mississippi River, which flows southward to the Gulf of Mexico. This watershed supports critical habitats for fish, migratory birds, and other aquatic species. Advanced treatment reduces nutrient loads, helping to mitigate hypoxia in the Gulf of Mexico.
