Yazoo City POTW - Municipal Wastewater Treatment in Yazoo County, Mississippi

Yazoo City POTW is a publicly owned treatment works located in Yazoo County, Mississippi, serving a population of about 14,550. The plant is situated in the Yazoo River basin, a major tributary of the Mississippi River, and plays a key role in managing wastewater for the surrounding community. As a medium-sized agglomeration, the plant is subject to the U.S. Clean Water Act, which requires secondary treatment as a baseline for municipal wastewater facilities. The National Pollutant Discharge Elimination System (NPDES) permits, issued by the Mississippi Department of Environmental Quality, govern discharge limits and monitoring requirements to protect water quality. The plant's treated effluent ultimately drains into the Yazoo River, which flows into the Mississippi River and then to the Gulf of Mexico. This downstream pathway highlights the plant's role in reducing nutrient and pollutant loads that can contribute to hypoxia in the Gulf, making effective treatment critical for regional water quality.

The plant discharges into the Yazoo River, a major tributary of the Mississippi River, which flows into the Gulf of Mexico. The Yazoo River basin supports diverse aquatic life and is an important migratory corridor for fish and birds. Downstream, the Mississippi River carries nutrient loads that contribute to the Gulf of Mexico's hypoxic zone, emphasizing the need for effective nutrient removal at treatment plants in this watershed.
