CANEYVILLE STP - Secondary Wastewater Treatment in Grayson County, Kentucky

CANEYVILLE STP is a municipal wastewater treatment facility located on Hunt Road in Grayson County, Kentucky, serving a population of 608. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal facilities discharging to surface waters. Its designed capacity is 378.54 cubic meters per day, with a current discharge volume of 264.98 cubic meters per day. As a secondary treatment plant, it uses biological processes to remove organic matter and suspended solids, meeting typical NPDES permit requirements for small communities. The treated effluent is discharged into local streams that drain into the Green River basin, a tributary of the Ohio River. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's location in rural Kentucky means it plays a key role in protecting local water quality in a region where agriculture and small towns rely on healthy streams.

The plant discharges into unnamed tributaries that flow into the Green River, a major tributary of the Ohio River. The Green River basin is ecologically significant, supporting diverse fish and mussel populations, including several endemic species. Downstream, the Ohio River feeds into the Mississippi River, ultimately reaching the Gulf of Mexico. The plant's secondary treatment helps reduce nutrient and organic loads, protecting aquatic habitats in this sensitive karst landscape.
