Overview

The City of Sioux City is served by a municipally-owned, 30 million gallons per day wastewater treatment plant located at 3100 South Lewis Blvd. (Rural Route 6), near the intersection of Interstate Highway 29 and U.S. Route 20.

Constructed in 1961, the Sioux City Regional Wastewater Treatment Plant serves five communities from three different states; including:

Sioux City, IA
Sergeant Bluff, IA
South Sioux City, NE
North Sioux City, SD
and Dakota Dunes, SD

On January 1, 2005, American Water entered into a 20-year contract with the City of Sioux City for the Operation and Maintenance of the municipally-owned treatment plant as well as the design and engineering of the Capital Improvements for the Wastewater Treatment Plant Rehabilitation Project.

The WWTP discharges into the Missouri River.
