Sidon POTW - Secondary Wastewater Treatment Plant in Sidon, Mississippi

Sidon POTW (Publicly Owned Treatment Works) serves the small community of Sidon in Leflore County, Mississippi. The plant provides secondary treatment for a population of 672, with a designed capacity of 227.12 volume units and a discharge volume of 227.13, indicating near-capacity operation. As a secondary treatment facility, Sidon POTW meets the minimum standard required by the US Clean Water Act for municipal wastewater plants. The plant operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Mississippi Department of Environmental Quality, which sets effluent limits to protect water quality. The treated effluent from Sidon POTW likely discharges into a tributary of the Yazoo River basin, which flows into the Mississippi River and ultimately the Gulf of Mexico. The plant's location in the Mississippi Delta region means its discharge contributes to the nutrient load in downstream waters, which is a key concern for hypoxia in the Gulf.

Sidon POTW discharges into the Yazoo River watershed, a major tributary of the Mississippi River. The Yazoo River flows through the Mississippi Delta, a region of rich agricultural land and diverse wetlands. Downstream, the Mississippi River carries nutrients and pollutants to the Gulf of Mexico, where they contribute to seasonal hypoxia zones. The plant's secondary treatment helps reduce organic pollutants but may not fully remove nutrients like nitrogen and phosphorus.
