Georgetown STP - Secondary Wastewater Treatment in Grant Parish, Louisiana

Georgetown STP is a municipal wastewater treatment facility located in Grant Parish, Louisiana, United States. It serves a small community of 288 residents, reflecting the rural character of the area. The plant is situated along State Route 500 and operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharge through National Pollutant Discharge Elimination System (NPDES) permits. The plant provides secondary treatment, a standard level for small communities in the US, which typically involves biological processes to reduce organic matter and suspended solids. The designed capacity is 196.84 megaliters, with an actual discharge volume of 113.56 megaliters per year, indicating operational headroom. As a small facility, it is subject to state-level oversight by the Louisiana Department of Environmental Quality. The treated effluent is discharged into a local water body, likely a tributary of the Ouachita River, which flows south to the Red River and ultimately into the Mississippi River and the Gulf of Mexico. The plant plays a role in protecting downstream water quality in this ecologically significant river system.

Georgetown STP discharges into a local watercourse that drains into the Ouachita River basin, part of the larger Mississippi River watershed. The Ouachita River supports diverse aquatic life, including fish and mussel species, and its floodplains provide critical habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and organic loads, mitigating potential impacts on downstream ecosystems and the Gulf of Mexico.
