Dandridge STP - Wastewater Treatment Plant in Dandridge, Tennessee

Dandridge STP is a municipal wastewater treatment plant located in Dandridge, Jefferson County, Tennessee. Serving a population of about 7,120, the facility is part of the region's infrastructure for managing domestic wastewater. The plant's location near the Douglas Lake reservoir places it within a sensitive watershed that feeds into the French Broad River system. As a U.S. facility, Dandridge STP operates under the National Pollutant Discharge Elimination System (NPDES) permit program, as required by the Clean Water Act. For plants serving populations between 5,000 and 10,000, secondary treatment is typically required to reduce biochemical oxygen demand and suspended solids. The plant's treatment processes are designed to meet these federal standards, ensuring compliance with water quality goals. The treated effluent from Dandridge STP discharges into the local watershed, which drains into Douglas Lake, a major reservoir on the French Broad River. This river eventually joins the Tennessee River and flows into the Ohio and Mississippi Rivers, ultimately reaching the Gulf of Mexico. The plant plays a crucial role in protecting downstream water quality and aquatic habitats in this extensive river system.

Dandridge STP discharges into the Douglas Lake watershed, part of the French Broad River basin. This river system supports diverse aquatic life, including several fish species and migratory birds. The Tennessee River basin is ecologically significant, providing habitat for freshwater mussels and serving as a corridor for wildlife. Protecting water quality in this region is essential for maintaining the health of downstream ecosystems, including the Mississippi River Delta.
