Southern Water and Sewer Eastern WWTP - Langley, Kentucky Wastewater Treatment Plant

Southern Water and Sewer Eastern WWTP is a municipal wastewater treatment facility located in Langley, Floyd County, Kentucky. The plant serves a small population of 220 residents, providing essential sanitation services to this rural community in the Appalachian region. The plant operates with secondary treatment, which is the standard level required under the US Clean Water Act for facilities of this scale. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 94.64 million gallons per day, with current discharge volumes averaging 15.14 million gallons per day. The treated effluent is discharged into local streams that are part of the Big Sandy River watershed, which ultimately flows into the Ohio River and then the Mississippi River. This waterway supports diverse aquatic life and provides drinking water for downstream communities. The plant's operations are regulated under the National Pollutant Discharge Elimination System (NPDES) permit program administered by the Kentucky Energy and Environment Cabinet.

The plant discharges into tributaries of the Big Sandy River, which flows northward to join the Ohio River near Ashland, Kentucky. The Ohio River then drains into the Mississippi River, eventually reaching the Gulf of Mexico. The watershed supports diverse aquatic species including several darter and minnow species, and provides habitat for migratory birds. The region's steep terrain and coal mining history make water quality management particularly important for protecting downstream ecosystems.
