Franklinton Wastewater Treatment Plant, Franklinton, Louisiana

The Franklinton wastewater treatment plant is a municipal facility located in Franklinton, Washington Parish, Louisiana. It serves a population of approximately 4,200 residents in this small community situated in the southeastern part of the state. As a US facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Louisiana Department of Environmental Quality. For a plant serving around 4,200 people, secondary treatment is typically required to meet effluent standards for biochemical oxygen demand and total suspended solids. The plant's treated effluent discharges to local waterways that ultimately drain into the Lake Pontchartrain Basin, a major estuarine system in southeastern Louisiana. This watershed supports diverse aquatic life and provides important habitat for fish and wildlife species in the region.

The Franklinton plant discharges into the Bogue Chitto River watershed, which flows into the Pearl River Basin and eventually reaches the Lake Pontchartrain estuary and the Gulf of Mexico. This coastal watershed supports diverse aquatic ecosystems, including freshwater and brackish habitats that are important for migratory fish and waterfowl.
