Gatlinburg WWTP - Wastewater Treatment in Gatlinburg, Tennessee

Gatlinburg WWTP is a municipal wastewater treatment facility located at 1045 Banner Road in Gatlinburg, Sevier County, Tennessee. Serving an estimated population of 28,700, the plant handles wastewater from this popular tourist destination in the Great Smoky Mountains region. The facility is part of the city's essential infrastructure, managing flows that vary significantly with seasonal tourism. Under the US Clean Water Act, plants of this scale are typically required to meet secondary treatment standards through the National Pollutant Discharge Elimination System (NPDES) permitting program. The Tennessee Department of Environment and Conservation oversees compliance, ensuring treated effluent meets water quality standards for the receiving environment. The regulatory framework mandates effective nutrient removal and pathogen control. The plant discharges treated wastewater into the Little Pigeon River watershed, which flows through the Great Smoky Mountains National Park and eventually joins the French Broad River, a tributary of the Tennessee River system. This river network supports diverse aquatic life, including trout populations, and provides drinking water for downstream communities. The plant's performance is critical to protecting the ecological health of this sensitive mountain stream ecosystem.

The plant discharges into the Little Pigeon River, a tributary of the French Broad River, which flows into the Tennessee River and ultimately the Mississippi River system. This watershed supports diverse aquatic species, including native brook trout and smallmouth bass, and provides habitat for numerous macroinvertebrates. The surrounding Great Smoky Mountains region is ecologically sensitive, with high rainfall and steep terrain that can affect stream flows and water quality. Maintaining low nutrient and pathogen levels in the effluent is essential to prevent eutrophication and protect downstream recreational and drinking water uses.
