ALLENDALE FAIRFAX STP is a municipal wastewater treatment plant located in Allendale, South Carolina, serving a population of about 19,813. The facility is situated inland, more than 50 kilometers from the coast, and treats wastewater from the Allendale area. As a US-based plant serving a medium-sized agglomeration, it operates under the National Pollutant Discharge Elimination System (NPDES) permit program established by the Clean Water Act. This regulatory framework requires secondary treatment as a minimum standard for municipal wastewater, with more stringent requirements for sensitive water bodies. The plant's design capacity and treatment process details are not publicly available in this dataset. The treated effluent is discharged into local waterways that ultimately drain to the Atlantic Ocean via the Savannah River basin. The plant plays a key role in protecting water quality in the region's rivers and downstream ecosystems, including estuarine habitats along the Georgia-South Carolina coast.

The plant discharges into the Savannah River watershed, which flows southeast through South Carolina and Georgia before emptying into the Atlantic Ocean near Savannah. This river system supports diverse aquatic life, including fish and migratory species, and its estuarine zone provides critical nursery habitats. The plant's operations help maintain water quality standards in this ecologically important basin.
