Fostoria WWTP is a municipal wastewater treatment facility located in Clay County, Iowa, United States. The plant serves a small population of 205 residents, reflecting its role in a rural community. It operates under the regulatory framework of the U.S. Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level required for most municipal facilities in the United States. Its designed capacity is 124.92 million gallons per year, with an actual discharge volume of 87.06 million gallons per year. This indicates the plant operates below its capacity, which is typical for small rural systems. The treated effluent is discharged into a local water body, likely a stream or river within the Missouri River basin.
