Guttenburg WWTP - Secondary Treatment Plant in Guttenberg, Iowa

Guttenburg WWTP is a municipal wastewater treatment facility located in Guttenberg, Iowa, along the Mississippi River. The plant serves a small community of about 1,986 residents and operates under secondary treatment standards, which is typical for smaller agglomerations in the United States. The plant has a designed capacity of 794.93 volume units and a discharge volume of 794.94, indicating near-full utilization. As a secondary treatment facility, it meets the requirements of the US Clean Water Act, which mandates secondary treatment for municipal plants to reduce organic pollutants and suspended solids before discharge. The treated effluent is discharged into local waterways that ultimately flow into the Mississippi River, a major ecological and economic corridor. The plant's location inland and away from coastal areas reduces direct marine impact, but its discharge contributes to the water quality of the Upper Mississippi River basin, which supports diverse aquatic life and recreational uses.

The plant discharges into tributaries of the Mississippi River, which flows south to the Gulf of Mexico. The Upper Mississippi River basin is ecologically significant, supporting diverse fish and bird species. The plant's secondary treatment helps protect downstream water quality, though nutrient removal may be limited without tertiary processes.
