Imperial Valley data-center developer sues for Colorado River water

Summary

A developer, Imperial Valley Computer Manufacturing, has sued the Imperial Irrigation District for access to ~260m gallons/yr of Colorado River water for a data center, turning to the courts to force supply on an over-allocated, drought-stricken river. It is one strand of a widening US litigation wave: Amazon settled a nitrate-pollution case for $20.5m; the Pyramid Lake Paiute Tribe sued Nevada and federal authorities over data-center-linked over-allocation; and Iowa officials found 40 unpermitted wells at a Cedar Rapids site. With lawmakers in 30+ states filing 300+ data-center bills in Q1 2026, water rights have become the legal battleground for AI siting, alongside the Tucson and Spanish fights.

By the numbers

• ~260m gal/yr, Colorado River water sought in the Imperial Valley suit.
• $20.5m, Amazon's data-center nitrate-pollution settlement.
• 40, unpermitted wells found at a Cedar Rapids, Iowa data-center site.
• 300+ / 30+, data-center bills filed / states acting (Q1 2026).

Why it matters

When permitting and local councils say no, developers and tribes alike are turning to the courts, making water-rights law, not just engineering, the gate on where AI compute can be built in the arid US.

What to watch

• The Imperial Irrigation District suit's progress and any precedent it sets.
• Outcomes of the Pyramid Lake Paiute and other tribal/over-allocation cases.
• New state laws tying data-center permits to water availability.
