The Information Technology and Innovation Foundation published "The Data Center Water Problem Is Soluble" on Monday, one week after a heat emergency in which AI data centers in the mid-Atlantic region drew evaporative cooling water from the same municipal supply that jurisdictions were restricting for residential use during 100-degree temperatures [1]. The report's institutional argument is specific: water regulators and electricity regulators operate in separate proceedings, and no joint review protocol exists to capture the full resource footprint of a data center application [1].

The practical consequence of that gap is that a facility requiring environmental review can receive energy permits from a state public utility commission and water withdrawal permits from a water authority without either agency seeing the combined picture. The ITIF report proposes watershed-based performance standards and a mandatory joint review process for large data center applications exceeding a defined load threshold [1].

The disclosure mandate is its most tractable near-term recommendation. The report calls for public reporting of total withdrawals, total consumption, source of water, peak-day demand, and full-build projections — what it calls "public-resource questions" that companies may have legitimate operational reasons to protect in other dimensions but cannot legitimately withhold from communities whose aquifers and municipal supplies they are drawing from [1].

Water use transparency functions, the report argues, as its own regulatory driver: companies rewarded for efficiency report; those that cannot report face disclosure-driven pressure from shareholders and municipalities before any regulator acts [1]. The alternative — allowing data center water use to remain in the current opacity — produced the heat-emergency outcome: officials restricting residential water use with no public accounting of what the largest co-located industrial consumers were drawing simultaneously [2].

The federal role the report envisions is narrow: national disclosure standards and technical support for state review processes, without preempting state water law or mandating national technology requirements [1]. State-level variation in water stress makes a one-size-fits-all national standard inappropriate; what the report proposes is a shared framework for the measurement, not a shared limit.
