Wyoming WWTP - Secondary Treatment Plant in Wyoming, Iowa

Wyoming WWTP is a municipal wastewater treatment plant located on Isabel Street in Wyoming, Jones County, Iowa. The facility serves a small population of 524 residents, reflecting the rural character of the community. As a secondary treatment plant, it provides biological treatment to remove organic matter and suspended solids from domestic wastewater. The plant operates under the U.S. Clean Water Act framework, which requires secondary treatment for municipal facilities. Its designed capacity of 227.12 units aligns closely with the current discharge volume of 227.13 units, indicating near-full utilization. The plant is subject to National Pollutant Discharge Elimination System (NPDES) permitting, administered by the Iowa Department of Natural Resources. The treated effluent is discharged into a local waterway that drains into the Maquoketa River watershed, eventually reaching the Mississippi River. This downstream connection to the Mississippi River system underscores the plant's role in protecting regional water quality and the broader Gulf of Mexico ecosystem.

The plant's discharge enters a small tributary within the Maquoketa River basin, which flows into the Mississippi River and ultimately the Gulf of Mexico. The Maquoketa River supports diverse aquatic life, including fish species such as smallmouth bass and channel catfish. The watershed is predominantly agricultural, with runoff from farms contributing nutrient loads that the plant's secondary treatment helps mitigate.
