ELGIN WWTP - Elgin, Iowa Wastewater Treatment Plant

ELGIN WWTP serves the community of Elgin, Iowa, a small town in Fayette County. The plant provides secondary treatment for a population of 637, managing an average daily flow of approximately 189,270 gallons with a designed capacity of 302,830 gallons per day. As a secondary treatment facility, ELGIN WWTP meets the standard requirements under the US Clean Water Act, which mandates secondary treatment for municipal wastewater plants. The plant's discharge is regulated through the National Pollutant Discharge Elimination System (NPDES) permit program, ensuring compliance with water quality standards. The treated effluent from ELGIN WWTP is discharged into a receiving water body that ultimately drains into the Mississippi River basin. This contributes to the overall water quality management of the region, supporting downstream aquatic ecosystems and recreational uses.

ELGIN WWTP discharges into local streams that flow into the Turkey River, a tributary of the Upper Mississippi River. The Mississippi River basin supports diverse aquatic life, including fish species such as walleye and smallmouth bass, and provides critical habitat for migratory birds. The plant's secondary treatment helps reduce nutrient and pollutant loads, protecting downstream water quality.
