A pair of data centers proposed for Tucson would use more water than four golf courses when fully built out, and be energized with more power than any other TEP customer, according to city documents released Monday. … The initial project, on the Southeast Side, will require annexation into the city to procure the massive amounts of water required to cool the planned operation. Another associated data center is being planned for a different location somewhere within the city limits, officials said. A third site is being studied for yet another data center in the region, but outside of the city limits, the city’s newly released documents said. The city posted the documents and a message from Thomure on a “Project Blue — Facts and Information” section of its website Monday afternoon. Just the first two sites combined would require nearly 2,000 acre-feet of water per year, making them Tucson Water’s largest customer.
