The Water Infrastructure Finance Authority of Arizona (WIFA) has advanced four water importation proposals, including multiple large-scale desalination concepts, into the study phase of its Long-Term Water Augmentation Fund (LTWAF) program. The move marks the latest step in the state’s effort to secure new, reliable water supplies.
WIFA selected proposals from two teams: the ACCIONA-Fengate Water Augmentation Alliance and EPCOR Water Innovation Partners. Seventeen teams originally submitted qualifications, followed by six full proposals. After review by evaluation teams and LTWAF committees, four projects were chosen for further study.
WIFA Board Chairman Jonathan Lines called the board’s vote a significant milestone, noting that the next phase will combine engineering analysis and public input to help shape long-term water strategies for Arizona.
- Gulf of California Desalination and Binational Conveyance — Acciona-Fengate Water Augmentation Alliance
- Northern Gulf of California Desalination Facility — EPCOR Water Innovation Partners
- South Bay Potable Water Reuse — EPCOR Water Innovation Partners
- California Groundwater Storage and Recovery — EPCOR Water Innovation Partners
According to WIFA, the study phase will evaluate engineering feasibility, financial approaches, environmental considerations, permitting needs, and community feedback. Reviewing multiple concepts in parallel is intended to help the agency determine which project or combination of projects may offer the most benefit to the state.
The analyses will involve collaboration with regional governments, water agencies, potential water purchasers, and community stakeholders.
LTWAF Committee Chairman Ted Cooke said the decision reflects Arizona’s continued focus on water stewardship and long-term planning.
