Kingston Springs STP - Secondary Wastewater Treatment in Kingston Springs, Tennessee

Kingston Springs STP is a municipal wastewater treatment facility located in Kingston Springs, Tennessee, a small community in Cheatham County. The plant serves a population of approximately 1,950 people, reflecting its role as a local infrastructure asset for the town. The plant provides secondary treatment, which is the standard level required under the U.S. Clean Water Act for municipal facilities of this scale. With a designed capacity of 946.35 thousand gallons per day and an average discharge volume of 681.37 thousand gallons per day, the plant operates 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, part of the larger Ohio River and Mississippi River systems. This downstream connection underscores the plant's role in protecting water quality in the region's aquatic ecosystems.

The plant discharges into receiving waters that flow into the Cumberland River, a major tributary of the Ohio River. The Cumberland River supports diverse aquatic life, including fish species such as bass and catfish, and provides habitat for freshwater mussels. Downstream, the river joins the Ohio and then the Mississippi, influencing water quality in the Gulf of Mexico. The plant's secondary treatment helps reduce nutrient and organic loads, mitigating potential impacts on these downstream ecosystems.
