Alburnett WWTP - Secondary Wastewater Treatment in Alburnett, Iowa

Alburnett WWTP is a municipal wastewater treatment facility located in Alburnett, Iowa, United States. The plant serves a small population of 451 residents, reflecting the rural character of the community. It operates under the regulatory framework of the U.S. 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 302.83 cubic meters per day and an average daily discharge of 189.27 cubic meters, the facility operates well within its capacity. As a small-scale plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permitting, which sets effluent limits to protect water quality. The treated effluent is discharged into a local water body that ultimately drains into the Mississippi River basin. The plant's location in Linn County places it within the Upper Mississippi River watershed, an ecologically significant region supporting diverse aquatic life and migratory birds. Proper treatment helps maintain the health of downstream waters.

The plant discharges into a tributary of the Cedar River, which flows into the Iowa River and then the Mississippi River. This watershed supports a variety of fish species and provides habitat for waterfowl. The Mississippi River is a major migratory corridor for birds and a vital freshwater resource for the central United States.
