Piney Woods Country Life School Wastewater Treatment Plant, Mississippi

The Piney Woods Country Life School wastewater treatment plant is located in Piney Woods, Rankin County, Mississippi. It serves a small population of 505 people, consistent with a rural school community. The plant operates under the U.S. Clean Water Act, which requires secondary treatment for municipal facilities of this scale. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. Its designed capacity is 302.83 volume units, and the current discharge volume is 109.78 volume units, indicating operational headroom. The facility is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the Mississippi Department of Environmental Quality. The treated effluent is discharged into local waterways that drain into the Pearl River basin, eventually reaching the Gulf of Mexico. The plant's inland location and secondary treatment help protect downstream aquatic habitats and water quality in the region.

The plant discharges into the Pearl River watershed, which flows south through Mississippi and Louisiana into the Gulf of Mexico. This basin supports diverse aquatic life, including fish and mussel species. The secondary treatment process reduces nutrient and organic loads, helping to maintain water quality in the river system and minimize impacts on downstream estuaries.
