CROWDER PWA WWT - Pittsburg County, Oklahoma Wastewater Treatment Plant

CROWDER PWA WWT is a municipal wastewater treatment facility located in Pittsburg County, Oklahoma, United States. The plant serves a small population of 436 residents, reflecting its role in a rural community. It operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater to protect water quality. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With an annual discharge volume of 151.42 megaliters and a designed capacity of 227.12 megaliters, the facility operates below its full capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local waterways that ultimately drain into the Arkansas River basin, contributing to the Mississippi River watershed. This inland location, over 50 km from the coast, reduces direct marine impact but requires careful management to protect freshwater ecosystems and downstream water quality.

The plant discharges into tributaries of the Arkansas River, which flows into the Mississippi River and eventually the Gulf of Mexico. The local watershed supports diverse aquatic life and is important for regional agriculture and recreation. As an inland facility, its effluent influences freshwater habitats and downstream water quality, necessitating effective treatment to prevent nutrient enrichment and protect biodiversity.
