Mayor Kate Gallego and the City of Phoenix Water Services Department celebrate the opening of the largest wastewater treatment biogas-to-renewable natural gas facility in the U.S.
The gas is a result of the natural breakdown of organic matter in the wastewater treatment process. Prior to this operation, the majority of this gas was burned off using flares. Through this new effort, 600,000 cubic feet of gas will be treated annually and transferred to a nearby commercial gas pipeline, where it will be sold on the open market as green energy. This facility is the largest wastewater treatment biogas-to-renewable natural gas facility of its kind in the United States.
The project is expected to produce $1.2 million in annual revenue, to be shared among the cities that jointly own the 91st Avenue Wastewater Treatment Plant. The 91st Avenue Wastewater Treatment Plant is the largest wastewater treatment plant in Arizona and the Southwest. It is jointly owned by the cities of Glendale, Mesa, Phoenix, Scottsdale, and Tempe.
