The facility serves a population of 577 and is classified as a small-scale treatment plant in the rural Great Plains region. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater facilities.

The plant discharges into tributaries of the Arkansas River, which flows through Oklahoma and Arkansas before joining the Mississippi River.
