Dardanelle WWTP is a municipal wastewater treatment facility located in Yell County, Arkansas, United States. It serves a population of about 4,745 people, classifying it as a small to medium-sized plant under US regulatory standards. The plant is situated inland, away from coastal areas, and its operations are governed by the Clean Water Act, which requires NPDES permits for discharges to surface waters. As a small agglomeration, the plant is expected to provide at least secondary treatment under federal regulations. Typical facilities of this scale in Arkansas employ activated sludge or lagoon systems to meet effluent limits. The plant's design and operation must comply with state water quality standards to protect receiving waters. The treated effluent from Dardanelle WWTP likely discharges into a nearby water body that drains into the Arkansas River system, ultimately reaching the Mississippi River and the Gulf of Mexico. This connection highlights the plant's role in maintaining water quality within the larger watershed, supporting aquatic life and downstream ecosystems.
Environmental context
The plant's discharge enters a local tributary that flows into the Arkansas River, a major tributary of the Mississippi River. The Arkansas River supports diverse aquatic species and provides habitat for migratory birds. Downstream, the Mississippi River carries water to the Gulf of Mexico, where nutrient loading can contribute to hypoxic zones. The plant's treatment performance is therefore important for regional water quality and ecological health.
