HWEA Crofton STP is a municipal wastewater treatment facility located on Sewer Plant Road in Christian County, Kentucky. The plant serves a small population of 935 residents and operates under the regulatory framework of the United States Clean Water Act, which requires secondary treatment for municipal discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 757.08 volume units and an average daily discharge of 681.37 volume units, the facility operates below its capacity, indicating reserve capacity for future growth or peak flows. The treated effluent is discharged into a local waterway within the Mississippi River basin. The plant's location in western Kentucky places it within a region of mixed agricultural and rural land use. The receiving water body ultimately drains to the Mississippi River and the Gulf of Mexico, supporting downstream aquatic ecosystems.

The plant discharges into a tributary of the Cumberland River or Tennessee River system, both part of the larger Mississippi River basin. The downstream environment includes the Mississippi River and the Gulf of Mexico, which supports diverse aquatic life and commercial fisheries. The plant's secondary treatment helps protect local streams from nutrient pollution and oxygen depletion.
