W and WW Authority of Wilson County Wastewater Treatment Plant, Lebanon, Tennessee

The W and WW Authority of Wilson County operates a municipal wastewater treatment plant located at 700 Maddox-Simpson Parkway in Lebanon, Tennessee. The facility serves a population of approximately 2,000 residents within Wilson County, part of the Middle Tennessee region. The plant provides secondary treatment, a standard level required by the U.S. Clean Water Act for municipal wastewater facilities. With a designed capacity of 283.91 thousand cubic meters per day and a current discharge volume of 200.63 thousand cubic meters per day, the plant operates within its capacity. 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. Treated effluent from the plant is discharged into local waterways that ultimately drain into the Cumberland River, a major tributary of the Ohio River and part of the Mississippi River system. The plant plays a key role in protecting water quality in the Cumberland River basin, which supports diverse aquatic life and provides drinking water for downstream communities.

The plant discharges into the Cumberland River watershed, which flows through Middle Tennessee before joining the Ohio River. The Cumberland River supports a variety of fish species and provides habitat for freshwater mussels. Downstream, the river feeds into the Mississippi River system, eventually reaching the Gulf of Mexico. Protecting this watershed is important for regional water quality and ecological health.
