Morrison North WWT - Secondary Wastewater Treatment in Morrison, Oklahoma

Morrison North WWT is a municipal wastewater treatment facility located in Morrison, Oklahoma, United States. The plant serves a small population of 318 residents, reflecting its role in a rural community within Noble County. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal discharges to protect water quality. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 185.48 units and an average daily discharge of 132.49 units, the facility operates below its maximum capacity, indicating adequate headroom for current demand. As a US facility, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits and monitoring requirements. The treated effluent is discharged into a local receiving water body, which ultimately drains into the Arkansas River watershed. This region is part of the Mississippi River basin, one of the largest drainage systems in North America. The plant's operations help protect downstream aquatic ecosystems and maintain water quality for the surrounding area.

The plant discharges into a local waterway that flows into the Arkansas River, a major tributary of the Mississippi River. The Arkansas River watershed supports diverse aquatic life and provides habitat for fish species such as catfish and bass. Downstream, the river passes through agricultural and urban areas before reaching the Mississippi, making nutrient and pollutant control critical for preventing eutrophication in the Gulf of Mexico.
