An upgrade to the Sioux City Wastewater Treatment Plant has been made that will reduce air emissions, improve odor control, and support our vision for a healthier city. The facility design, engineered by Bartlett & West of Des Moines, recovers methane and carbon dioxide produced through wastewater treatment and converts it into a renewable natural gas, making operations more efficient.
Onsite production of renewable natural fuel will create new revenue streams through the nationwide natural gas market, which may offset the need for some future rate increases. The renewable natural gas that is produced will be used for vehicle fuel. Over time, the project is expected to pay for itself and position Sioux City as a unique, visionary leader in the Midwest region with one of the greenest renewable natural gas projects to date.
Sioux City is the second wastewater facility in the state of Iowa and one of the first five in the country to do this.
Contruction began in 2018 and became operational in late 2020.
