## Summary

The [water](/hi/entity/data-center-water) backlash against [data centers](/hi/entity/data-centers) has hardened
in Arizona. After the Tucson City Council unanimously rejected involvement with the Project
Blue complex (originally Amazon-linked) over a region that gets 7–10 inches of rain a year,
the city revoked a construction water meter when the contractor used ~two acre-feet of city
drinking water for dust control the council had explicitly refused, and demanded payback.
Arizona water regulators nonetheless approved two wells letting the site draw up to ~96.5
acre-feet/yr of groundwater. The standoff sits in a wider Western pattern (Georgia,
California) of local fights over the campuses' thirst, echoing the
[Imperial Valley](/hi/n/imperial-valley-datacenter-water-lawsuit) dispute and Europe's
[Spanish](/hi/n/spain-datacenter-water-fights-2026) protests.

## By the numbers

- 7–10 in, average annual rainfall in the Tucson region.
- ~96.5 acre-ft/yr, groundwater approved across Project Blue's two wells.
- ~2 acre-ft, city drinking water improperly used, triggering the meter revocation.
- ~20, US data-center projects cancelled or stalled amid local pushback (Q1 2026).

## Why it matters

Water, not just power, is now a binding political constraint on AI siting in the arid
West. A city cutting off a flagship campus signals that local control over scarce
groundwater can stop or reroute multibillion-dollar builds.

## What to watch

- Whether Project Blue proceeds on groundwater alone after the city cutoff.
- Litigation or referenda over data-center water rights in Arizona.
- Spillover to other Western siting decisions.
