East Leflore County WandS District Wastewater Treatment Plant, Greenwood, Mississippi

East Leflore County WandS District is a municipal wastewater treatment plant located in Greenwood, Mississippi, within the United States. The facility serves a population of approximately 2,055 residents, classifying it as a small-scale treatment operation under the regulatory framework of the US Clean Water Act. The plant provides secondary treatment, which is the standard level required by the US Environmental Protection Agency (EPA) for municipal wastewater facilities. With a designed capacity of 605.66 volume units and a current discharge volume of 170.34 volume units, the plant operates well within its capacity, indicating adequate infrastructure for its service area. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River basin. This region supports diverse aquatic life and is part of the larger Mississippi River watershed, which is ecologically significant for its role in nutrient cycling and habitat provision. The plant's operations are subject to National Pollutant Discharge Elimination System (NPDES) permits to ensure compliance with water quality standards.

The plant discharges into the Yazoo River basin, which flows into the Mississippi River and eventually the Gulf of Mexico. This watershed is ecologically sensitive due to nutrient loading concerns that contribute to the Gulf of Mexico hypoxic zone. The plant's secondary treatment helps reduce organic pollutants, but nutrient removal may be limited without tertiary processes.
