Arizona: Turning Wastewater Emissions into RNG and Local Art
Pima County, Arizona, has consumed raw biogas to fuel the engines used at the Tres Rios sewer plant for many years. A study from 2014 concluded it would be more economical to refine the Tres Rios' raw biogas into sellable RNG, and construction of the plant was subsequently approved. The county signed an agreement with a biogas joint venture to build the RNG treatment facility and market the gas. Eventually, the joint venture stalled, but Pima County decided to move forward constructing the plant on its own and partnering with Southwest Gas.
In an effort to help the local community achieve energy sustainability with reduced emissions, Southwest Gas acts as a catalyst to bring sources of RNG to consumers. Southwest Gas' plans for a sustainable energy future and Pima County's decision to market the highest-quality gas led to finding a company specializing in evaluating gas quality to enable the merchantability of the Tres Rios product. Mustang Sampling was chosen to provide a turnkey, Analytically Accurate solution to guarantee a verifiable supply of sustainable, clean and safe RNG.
