The second track of the Arizona Water Initiative involved the creation of a Governor’s Water Augmentation Council that investigated long-term water augmentation strategies, additional water conservation opportunities, funding and infrastructure needs to help secure water supplies for Arizona’s future.  The role of the "GWAC" was expanded on January 31, 2019, bya new executive order by Governor Ducey. The new Council, which would include many of the original panel's members, would be charged further with investigating innovative methods of expanding the state's water resources, as well as targeting conservation efforts.

In the fall of 2016, four committees were created by Council Chairman, Tom Buschatzke, that would specialize in fields that either directly or indirectly affect water augmentation opportunities in Arizona. These fields include desalination, finance, recycled water, and long-term water augmentation. Each of the committees are chaired by Council members who volunteered for the position, and the committee members comprised of Council members, representatives of Council members, or individuals selected by the Committee Chair. They typically hold meetings hold meetings every two months, they are open to the public, and the presentations and summaries for each meeting can be found below.
