SLOAN WWTP - Woodbury County, Iowa Wastewater Treatment Plant

SLOAN WWTP is a municipal wastewater treatment facility located in Woodbury County, Iowa, United States. The plant serves a small population of approximately 973 residents in the Sloan Township area. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal wastewater discharges. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 794.93 million gallons per year and an actual discharge volume of 302.83 million gallons per year, the facility operates well below its capacity. The plant is permitted under the National Pollutant Discharge Elimination System (NPDES) program, which sets effluent limits to protect water quality. The treated effluent is discharged into local waterways that drain into the Missouri River, a major tributary of the Mississippi River. The plant's location in the Missouri River basin means its discharge contributes to the overall water quality of this important river system, which supports diverse aquatic life and provides water for communities downstream.

The plant discharges into the Missouri River basin, which flows into the Mississippi River and ultimately the Gulf of Mexico. The Missouri River supports a variety of fish species and provides habitat for migratory birds. The plant's secondary treatment helps reduce nutrient loads that could contribute to hypoxia in the Gulf of Mexico.
