Tucson pulled Project Blue's construction water meter on May 4. About 2 acre-feet of water has to come back.
Quick breakdown for anyone who's been following Project Blue but didn't catch the May 4 letter.
Tucson Water had issued a temporary construction-water meter to Ames Construction for use at the Project Blue site. Ames picked it up on April 24 and used it for dust control. A resident raised the question with a Ward 4 staffer, and on May 4, Tucson City Manager Tim Thomure's letter pulled the meter and told Beale Infrastructure to "make Tucson's water supply whole" by handing back 2 acre-feet (about 650,000 gallons) of water credits.
What I don't think comes through in most of the national coverage: Thomure didn't need a Council vote to do this.
Council already unanimously rejected Project Blue last year. The site sits in unincorporated Pima County, past city limits in the Houghton/Vail direction, outside Tucson Water's authorized service area. That construction meter was a one-off Tucson never had to issue in the first place, which means it's a one-off the City Manager could revoke without going back to Council. The May 4 letter is the cleanup pass on a decision Council had already made.
Side note on how I got here: I keep a small dataset of US AI data centers and the water utilities that serve them. When I tried to add Project Blue this week, the site coordinates fell outside Tucson Water's service area in the data too. Same fact, different form.
One ask for anyone closer to this than I am: does anyone have a confirmed lat/lng for the Project Blue construction site? The Beale filings reference a few different addresses around Houghton and I want to pin the right one down.
