Winnsboro Industrial WWTP - Secondary Treatment Facility in Winnsboro, Louisiana

Winnsboro Industrial WWTP is a municipal wastewater treatment facility located in Winnsboro, Franklin Parish, Louisiana, United States. The plant serves a small population of around 500 people, reflecting its role in a rural community. The plant provides secondary treatment, which is the standard level required under the US Clean Water Act for most municipal facilities. With a designed capacity of 378.54 megaliters per year and an actual discharge volume of 37.85 megaliters per year, the plant operates well below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into local waterways that ultimately drain into the Mississippi River basin. The plant's inland location, over 50 km from the coast, reduces direct marine impact, but its discharge contributes to the overall water quality of the region's river systems, which support diverse aquatic life and are important for downstream ecosystems.

The plant discharges into local tributaries that flow into the Ouachita River, part of the larger Mississippi River basin. This watershed supports a variety of fish and wildlife, including migratory species. The secondary treatment helps reduce organic pollutants and suspended solids, protecting downstream water quality in the ecologically significant Mississippi River Delta.
