Griffithville WWTP - Advanced Wastewater Treatment in Griffithville, Arkansas

Griffithville WWTP is a municipal wastewater treatment facility located on Walker Road in Griffithville, White County, Arkansas, United States. The plant serves a small population of 225 residents, reflecting the rural character of the area. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 177.91 units and a daily discharge volume of 219.55 units, the facility operates under the regulatory framework of the U.S. Clean Water Act, administered by the Arkansas Department of Energy and Environment. Such small plants are typically subject to state-level NPDES permits that set effluent limits based on the receiving water body's assimilative capacity. The treated effluent is discharged into a local water body that ultimately drains into the Arkansas River watershed, part of the larger Mississippi River Basin. The plant's advanced treatment helps protect downstream aquatic ecosystems, including the Arkansas River and its tributaries, which support diverse fish and wildlife populations.

The plant discharges into a local stream that flows into the Arkansas River, a major tributary of the Mississippi River. The Arkansas River watershed supports diverse aquatic life and is an important migratory corridor for birds. The plant's advanced treatment helps maintain water quality in this ecologically sensitive region, reducing nutrient loading that could otherwise contribute to hypoxia in the Gulf of Mexico.
