The plant serves a small population of 47 residents, reflecting its role in a rural or small community setting within Cleburne County. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 94.64 million gallons per year and an actual discharge volume of 15.14 million gallons per year, the facility operates well below its capacity, indicating room for future growth or seasonal variability. As a US plant, it operates under the Clean Water Act, with National Pollutant Discharge Elimination System (NPDES) permits issued by the Arkansas Department of Energy and Environment - Division of Environmental Quality. The treated effluent is discharged into a local water body, likely a tributary of the Arkansas River or the Greers Ferry Lake watershed. The plant's advanced treatment helps protect downstream water quality in the Arkansas River basin, which ultimately drains into the Mississippi River and the Gulf of Mexico. This is particularly important for maintaining ecological health in the region's lakes and rivers.
