The facility serves a population of about 11,667, classifying it as a medium-sized agglomeration under US EPA guidelines. The plant's designed capacity is 1.00 million gallons per day, reflecting its role in managing local wastewater. As a US facility, ABBEVILLE STP operates under the Clean Water Act's National Pollutant Discharge Elimination System (NPDES) permit program. For plants serving populations between 10,000 and 100,000, secondary treatment is typically required to reduce biochemical oxygen demand and suspended solids. The regulatory framework ensures compliance with federal effluent guidelines. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Vermilion River and then into the Gulf of Mexico. This coastal drainage system supports diverse aquatic habitats, including estuarine environments important for fish and shellfish. Proper treatment is essential to protect downstream water quality and the ecological health of the Gulf Coast region.
