Memphis S T E MAXSON WWTP: Major Wastewater Treatment Plant in Memphis, Tennessee

Memphis S T E MAXSON WWTP is a major municipal wastewater treatment facility located in Memphis, Tennessee, along the Mississippi River. Serving a population of over 333,000, it is one of the key plants in the region's wastewater infrastructure, operating under the regulatory framework of the U. S. Clean Water Act. As a large-scale treatment plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Tennessee Department of Environment and Conservation. These permits set effluent limits to protect water quality. The plant's treatment processes are designed to meet secondary treatment standards, which are typical for facilities of this size under federal regulations. The treated effluent is discharged into the Mississippi River, a major waterway that drains into the Gulf of Mexico. The plant plays a critical role in protecting the river's water quality and the downstream ecosystems, including the Mississippi River Delta and the Gulf's marine environment. Its operations help reduce nutrient loading and other pollutants that could impact aquatic life and drinking water sources.

The plant discharges into the Mississippi River, which flows south through the Mississippi River Delta into the Gulf of Mexico. This watershed supports diverse aquatic habitats and is a critical migratory corridor for fish and birds. Nutrient pollution from wastewater can contribute to hypoxic zones in the Gulf, making effective treatment essential for downstream ecological health.
