LIVERMORE STL Wastewater Treatment Plant, Humboldt County, Iowa

LIVERMORE STL is a municipal wastewater treatment plant located in Humboldt County, Iowa, United States. The plant serves a small population of 431 residents, reflecting its role in a rural community. It operates under the regulatory framework of the U.S. Clean Water Act, which requires National Pollutant Discharge Elimination System (NPDES) permits for all discharges into surface waters. The plant provides secondary treatment, a standard level for small communities in the United States. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 416.39 million gallons per year and currently discharges 113.56 million gallons per year, indicating it operates well below its capacity. The treated effluent is discharged into a local water body, likely a stream or river within the Mississippi River Basin. The plant's operations help protect downstream water quality in the region, supporting aquatic life and recreational uses. As an inland facility, it does not directly impact coastal environments.

The plant discharges into a local water body that is part of the Mississippi River Basin, which ultimately drains into the Gulf of Mexico. This watershed supports diverse aquatic ecosystems and is important for agriculture and recreation in the Midwest. The plant's secondary treatment helps reduce nutrient loads that could contribute to hypoxia in the Gulf.
