In 2022, the Arizona Legislature placed significant new authorities, responsibilities, and funds with WIFA. One of these funds is the Long-Term Water Augmentation Fund, a forward-thinking $1 billion investment in water augmentation. WIFA has been tasked with administering the fund by investing in projects designed to import new water into Arizona for the benefit of current and future users, the economy, and the environment. 

The LTWAF will help finance water supply development with at least 75% of the funds being used for opportunities that import water from outside the state and up to 25% of the funds available for in-state augmentation projects.
