Weiner WWTP - Advanced Wastewater Treatment in Weiner, Arkansas

Weiner WWTP is a municipal wastewater treatment plant located in Weiner, Arkansas, United States. The facility serves a small population of 777 residents in this rural community within Poinsett County. As an advanced treatment plant, it provides a high level of effluent quality to protect local water resources. The plant reports an annual discharge volume of 340.69 thousand cubic meters and a designed capacity of 2271.24 thousand cubic meters, indicating substantial reserve capacity. Operating under the U.S. Clean Water Act, the facility is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits and monitoring requirements to safeguard water quality. The treated effluent is discharged into a local water body that ultimately drains into the Mississippi River basin. This region is part of the larger Mississippi River watershed, which supports diverse aquatic ecosystems and provides drinking water for millions downstream. Advanced treatment helps minimize nutrient and pollutant loads, contributing to the ecological health of the receiving waters.

The plant discharges into a local watercourse that flows into the Mississippi River basin, a major drainage system supporting extensive aquatic habitats and migratory bird routes. Advanced treatment reduces nutrient enrichment risks in downstream waters, including the Gulf of Mexico, where nutrient pollution contributes to hypoxic zones. The facility's inland location and advanced treatment help protect local streams and the broader watershed.
