A state board tasked with vetting water supply augmentation proposals for Arizona on Tuesday passed a nonbinding resolution in support of a potentially massive seawater desalination plant in Mexico’s Sea of Cortez. A partnership led by Israeli desalination specialists IDE Technologies pitched the multibillion-dollar plan to the Water Infrastructure Finance Authority of Arizona’s board, saying it could replace or complement declining Colorado River water that flows through the Central Arizona Project’s canal. The plant would remove salt from seawater and pump it north into the canal, where it would flow through Maricopa, Pinal and Pima counties.
