Tucson city officials and the developers of Project Blue — a planned complex of data centers for Amazon — faced a fractious crowd hundreds strong Wednesday night as they attempted to make their case the project will be “water positive” and will not drive up electric rates, while trying to defend non-disclosure agreements that still keep information from the public. … During the first two years, the project will use drinking water for cooling, but will switch to reclaimed water. … At one point, a speaker asked [Tucson City Manager Tim] Thomure how they would enforce the two-year promise to halt using drinking water, noting that the draft agreement includes caps but breaking those caps won’t mean the city cuts off the water supply; instead, the city will just add extra charges.
