Arizona Water Supply Expansion Proposals

under review

Arizona's Water Infrastructure Finance Authority (WIFA) is reviewing six proposals to expand the state's water supply in response to ongoing Colorado River shortages. The proposals include seawater desalination, surface water, wastewater reclamation, and other new sources. Three of the proposals focus on desalination, including plans by EPCOR, ZARETAW LLC with a desalination and pipeline project from the Sea of Cortez to central Arizona, and the Acciona–Fengate Water Augmentation Alliance. The proposals are under initial review to determine which meet the criteria for feasibility studies, with final selections expected by the end of 2025.
