ARCOLA POTW - Secondary Wastewater Treatment Plant in Arcola, Mississippi

ARCOLA POTW is a municipal wastewater treatment plant located in Arcola, Washington County, Mississippi, United States. The facility serves a small population of 564 residents and operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 340.69 megaliters and an annual discharge volume of 151.42 megaliters, the plant operates well below its capacity, indicating room for future growth. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River basin. The plant plays a key role in protecting downstream water quality in the Mississippi Delta region, an ecologically important area that supports diverse aquatic life and agricultural activities.

The plant discharges into the Mississippi River watershed, which flows into the Gulf of Mexico. The Mississippi Delta is a critical ecological region that supports fish, migratory birds, and other wildlife. The plant's secondary treatment helps reduce nutrient loading and protect downstream water quality in this sensitive aquatic environment.
