Wiggins POTW Number 2 - Secondary Wastewater Treatment in Wiggins, Mississippi

Wiggins POTW Number 2 is a municipal wastewater treatment plant located in Wiggins, Stone County, Mississippi, serving a population of approximately 1,153 residents. The facility operates under the regulatory framework of the United States Clean Water Act, which requires secondary treatment for municipal wastewater to protect water quality. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 598.09 m³/day and a current discharge volume of 757.08 m³/day, the facility operates within its capacity parameters. As a small-scale plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Mississippi Department of Environmental Quality, ensuring compliance with effluent limits. The treated effluent is discharged into local streams that drain into the Pascagoula River basin, ultimately reaching the Gulf of Mexico. The plant plays a key role in protecting downstream aquatic ecosystems and maintaining water quality in the region's coastal watershed.

The plant discharges into tributaries of the Pascagoula River, one of the last free-flowing river systems in the contiguous United States, which flows into the Mississippi Sound and the Gulf of Mexico. This watershed supports diverse aquatic life, including fish and shellfish, and provides critical habitat for migratory birds. The secondary treatment helps reduce nutrient loading and organic pollution, safeguarding downstream estuarine environments.
