LOYALL STP - Wastewater Treatment Plant in Loyall, Kentucky

LOYALL STP is a wastewater treatment plant located in Loyall, Kentucky, a small community in Harlan County. The plant serves a population of approximately 1,007 residents, reflecting its role as a small-scale municipal facility in the Appalachian region. The plant provides secondary treatment, a standard level for small communities under the U.S. Clean Water Act. With a designed capacity of 700.30 million gallons per year and an actual discharge volume of 105.99 million gallons, the plant operates well below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into local waterways that ultimately drain into the Cumberland River basin, a major tributary of the Ohio River. This watershed supports diverse aquatic life and provides drinking water for downstream communities, making proper treatment essential for environmental and public health.

The plant's discharge enters streams within the Cumberland River watershed, which flows into the Ohio River and eventually the Mississippi River. This region is characterized by mountainous terrain and coal mining history, which can affect water quality. The secondary treatment process helps reduce organic pollutants and suspended solids, protecting aquatic habitats in the receiving waters.
