MARTIN STP Wastewater Treatment Plant, Weakley County, Tennessee

MARTIN STP is a wastewater treatment plant located in Weakley County, Tennessee, serving a population of about 10,905 residents. The facility is part of the municipal infrastructure managed by local authorities in the West Tennessee region. Under the U.S. 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 treatment process and capacity details are managed by the operating entity to ensure compliance with state and federal regulations. The plant discharges treated effluent into local waterways that drain into the Mississippi River basin, ultimately reaching the Gulf of Mexico. This connection underscores the importance of effective treatment to protect downstream aquatic ecosystems and water quality.

The plant's treated effluent flows into tributaries of the Mississippi River, which carries water through the Mississippi Delta to the Gulf of Mexico. This watershed supports diverse aquatic life and is an important migratory corridor for fish and birds. Effective nutrient removal is critical to mitigate hypoxic zones in the Gulf.
