The plant is situated in Grant County, part of the state's rural landscape, and operates under the regulatory framework of the United States Clean Water Act. The plant employs advanced treatment processes, ensuring a high level of pollutant removal before discharge. With a designed capacity of 1,109.12 thousand cubic meters per year and an actual discharge volume of 969.07 thousand cubic meters, the facility operates below its capacity, indicating room for future growth or seasonal variations.

The plant discharges into local streams that flow into the Pomme de Terre River, a tributary of the Minnesota River, which joins the Mississippi River. The Mississippi River basin supports diverse aquatic life and is a critical migratory corridor for birds and fish. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality in the Minnesota River and ultimately the Gulf of Mexico.
