Centerville WWTP, Buffalo, Texas | Secondary Treatment Facility

Centerville WWTP is a municipal wastewater treatment facility located in Buffalo, Texas, United States. It serves a small community of approximately 900 people, reflecting its role in managing local wastewater for a rural area in Leon County. The plant provides secondary treatment, which is the standard biological treatment process required by the U.S. Clean Water Act for most municipal facilities. Under the National Pollutant Discharge Elimination System (NPDES), plants of this scale are typically permitted by the Texas Commission on Environmental Quality (TCEQ) to ensure compliance with effluent limits that protect water quality. The treated effluent from Centerville WWTP is discharged into a local water body that ultimately drains into the Trinity River basin, which flows into the Gulf of Mexico. This downstream connection underscores the plant's role in safeguarding regional water quality and supporting aquatic ecosystems in the Trinity River watershed.

The plant discharges into a receiving water body within the Trinity River basin, which flows southeast through Texas to Trinity Bay and the Gulf of Mexico. The watershed supports diverse aquatic life, including fish and migratory birds, and is ecologically sensitive to nutrient loading. Secondary treatment helps reduce organic pollutants and suspended solids, protecting downstream habitats from eutrophication and maintaining water quality for recreational and ecological uses.
