LEXINGTON E LAGOON Wastewater Treatment Plant, Lexington, Tennessee

LEXINGTON E LAGOON is a wastewater treatment facility located in Lexington, Tennessee, within Henderson County. The plant serves a population of about 13,889 residents, placing it in the medium agglomeration category for US municipal wastewater systems. The plant operates under the US Clean Water Act, which requires secondary treatment for municipal wastewater discharges. Lagoon systems are common in rural areas and typically provide secondary treatment through natural biological processes. The designed capacity is 1.00 million gallons per day. The treated effluent from the plant is discharged into local waterways that ultimately drain into the Tennessee River basin. The Tennessee River flows into the Ohio River, then the Mississippi River, and finally the Gulf of Mexico. The plant plays a key role in protecting water quality in the region's streams and rivers.

The plant discharges into local streams that are part of the Tennessee River watershed. The Tennessee River flows westward to join the Ohio River, which then empties into the Mississippi River and the Gulf of Mexico. The region's aquatic ecosystems support diverse fish and wildlife, including several species of freshwater mussels and migratory birds. Proper wastewater treatment is essential to prevent nutrient pollution and maintain water quality in these downstream waters.
