The plant is situated in Union County, within the Ohio River watershed, and operates as part of the region's water infrastructure. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal wastewater. With a designed capacity of 605.66 m³/day and a current discharge volume of 378.54 m³/day, the facility operates below its capacity.

The treated effluent from Uniontown STP is discharged into a local waterway that ultimately drains into the Ohio River, a major tributary of the Mississippi River system. The Ohio River supports diverse aquatic life and provides drinking water for millions downstream. The plant's secondary treatment helps protect water quality in this ecologically significant river basin.

Uniontown STP discharges into a small tributary that flows into the Ohio River, which then joins the Mississippi River before reaching the Gulf of Mexico. The Ohio River is a critical waterway for aquatic biodiversity, supporting species such as freshwater mussels and migratory fish. The plant's secondary treatment reduces organic pollutants and suspended solids, helping maintain the ecological health of the downstream river system.
