Air Force to Pay for Tucson Water Treatment Facility

The City of Tucson will be reimbursed nearly $17 million by the United States Air Force for the design and construction of the AOP Water Treatment Facility.

Advanced Oxidation Process (AOP) technology is used to treat groundwater contaminated with 1,4-dioxane, which was used by aircraft manufacturing companies in the Tucson airport area from the 1940s to 1970s. The process combines ultraviolet light with hydrogen peroxide to purify up to 8 million gallons of water a day.

Uncertain that the cost of the facility would be reimbursed, Tucson Water opened the plant in January 2014 to ensure the containment was removed from local drinking water.

The facility was awarded the 2015 Grand Prize in Design from the American Academy of Environmental Engineers and Scientists.
