PLEASANT HILL UPLAND RET Wastewater Treatment Plant, Pleasant Hill, Tennessee

PLEASANT HILL UPLAND RET is a municipal wastewater treatment plant located in Pleasant Hill, Tennessee, serving a population of approximately 2,500 residents. The facility is situated in Cumberland County within the East Tennessee region, an area characterized by rolling hills and karst topography. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater. With a designed capacity of 1,514.16 m³/day and an actual discharge volume of 946.35 m³/day, the plant operates below its capacity, indicating room for future growth. As a U.S. facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Tennessee Department of Environment and Conservation, ensuring compliance with effluent limits. The treated effluent is discharged into nearby streams that ultimately drain into the Cumberland River watershed, a major tributary of the Ohio River and Mississippi River system. This water body supports diverse aquatic life and provides drinking water for downstream communities. The plant's operations help protect local water quality in the ecologically sensitive karst landscape of East Tennessee.

The plant discharges into local streams that flow into the Cumberland River, which joins the Ohio River and then the Mississippi River before reaching the Gulf of Mexico. The Cumberland River watershed supports diverse aquatic species, including several endemic mussels and fish. The karst geology of the region makes groundwater particularly vulnerable to contamination, emphasizing the importance of effective wastewater treatment.
