NOWATA CO RWandSD 1 WANN Wastewater Treatment Plant, Wann, Oklahoma

NOWATA CO RWandSD 1 WANN is a municipal wastewater treatment facility located in Wann, Nowata County, Oklahoma. It serves a small population of 280 residents, reflecting the rural character of the area. The plant is situated at 253 Main Street and provides essential sanitation services to the local community. The plant employs secondary treatment, which is the standard biological process required by the US Clean Water Act for most municipal facilities. Secondary treatment typically involves biological oxidation and sedimentation to remove organic matter and suspended solids. The plant has a designed capacity of 113.56 volume units and currently discharges a similar volume, indicating full utilization. As a US facility, it operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Oklahoma Department of Environmental Quality, which sets effluent limits to protect water quality. The treated effluent is discharged into a local water body, likely a tributary of the Verdigris River or Caney River, which eventually flows into the Arkansas River and then the Mississippi River system. This drainage contributes to the Gulf of Mexico watershed. The plant's operation helps protect downstream aquatic habitats and supports the ecological health of the region's rivers and streams.

The plant discharges into a local stream that is part of the Arkansas River basin, ultimately draining into the Mississippi River and the Gulf of Mexico. The receiving waters support diverse aquatic life, including fish and macroinvertebrates, and are important for regional biodiversity. The small population served means the plant's nutrient and pollutant loads are relatively low, but proper treatment remains critical to prevent localized eutrophication and maintain water quality in downstream ecosystems.
