Council Bluffs WWTP - Iowa Wastewater Treatment Plant Serving 54,315

Council Bluffs WWTP is a municipal wastewater treatment facility located in Council Bluffs, Iowa, serving a population of about 54,315. The plant is situated near the Missouri River and plays a key role in managing wastewater for the city and surrounding areas. As a U.S. facility of this scale, the plant is subject to the Clean Water Act and operates under a National Pollutant Discharge Elimination System (NPDES) permit issued by the Iowa Department of Natural Resources. For a population of this size, secondary treatment is typically required, with additional nutrient removal standards in sensitive watersheds. The plant's treated effluent is discharged into the Missouri River, which flows south to join the Mississippi River and ultimately the Gulf of Mexico. This discharge contributes to the overall water quality of the Missouri River basin, supporting aquatic life and downstream uses.

The plant discharges into the Missouri River, a major tributary of the Mississippi River that drains into the Gulf of Mexico. The Missouri River supports diverse aquatic species and is an important migratory corridor for fish. Downstream water quality is influenced by nutrient loads from wastewater and agricultural runoff, making treatment standards critical for preventing eutrophication in the Gulf.
