CRUGER POTW - Secondary Wastewater Treatment Plant in Cruger, Mississippi

CRUGER POTW is a publicly owned treatment works located in Cruger, Holmes County, Mississippi, serving a small community of 472 residents. The plant provides secondary treatment, a standard level for small agglomerations in the United States, ensuring compliance with Clean Water Act requirements. With a designed capacity of 264.98 megaliters per year and an actual discharge volume of 227.13 megaliters per year, the plant operates below its capacity. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Mississippi Department of Environmental Quality, which set effluent limits for pollutants. The plant discharges treated wastewater into a local waterway that ultimately drains into the Yazoo River basin, a major tributary of the Mississippi River. This contributes to the ecological health of the region's aquatic systems, supporting diverse fish and wildlife habitats.

The plant's discharge enters a local stream within the Yazoo River watershed, which flows into the Mississippi River and eventually the Gulf of Mexico. This downstream chain supports important aquatic ecosystems, including wetlands and floodplains that provide habitat for migratory birds and fish species. The secondary treatment process helps reduce nutrient loads, protecting water quality in the sensitive delta region.
