Nora Springs Wastewater Treatment Plant, Iowa | Small Community Facility

The Nora Springs wastewater treatment plant is a municipal facility located in Nora Springs, Floyd County, Iowa, United States. It serves a population of approximately 1,411 residents, making it a small-scale treatment operation within the state's wastewater infrastructure. As a plant serving fewer than 2,000 people, it falls under the U.S. Clean Water Act's regulatory framework, which requires secondary treatment as a baseline for municipal wastewater facilities. The plant is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Iowa Department of Natural Resources, ensuring compliance with effluent limitations. The plant discharges treated wastewater into local waterways that ultimately drain into the Mississippi River basin. Its inland location and small population served reduce its environmental footprint, though proper treatment remains essential to protect downstream water quality and aquatic habitats.

The plant discharges into tributaries of the Cedar River, which flows into the Iowa River and then the Mississippi River. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's treatment performance is critical to maintaining water quality in this agriculturally intensive region.
