The License to Operate
A cooling design that is elegant on paper can still be un-buildable, because water is the most local and most political resource an operator touches. A megawatt of power can be wheeled across a region; a gallon of water cannot, and the people who share the aquifer get a vote, through permits, through drought rules, through the local newspaper. The last few years turned water from an engineering input into a license-to-operate risk: projects delayed, moratoria declared, campaigns launched over how many households' worth of water a campus would drink. Serious developers now treat community and regulatory standing as a design constraint that arrives before the first chiller is ever specified.

Why does water risk constrain where a data center can be built in a way that power risk does not?
Show the answer
Because water is intensely local and cannot be transported across regions the way electricity can, so a project must satisfy the specific basin, regulators, and community it draws from, making water a siting and license-to-operate constraint rather than a commodity that can simply be sourced from somewhere less scarce.
