THE GEOGRAPHY OF THIRST: WHY WATER DICTATES DEPLOYMENT
Historically, some of the most attractive markets for data centre expansion were situated in arid or semi-arid regions. Areas like the US Southwest offered vast tracts of affordable land and abundant solar energy potential.
However, these same regions are now facing intense scrutiny from local municipalities and environmental regulators due to severe groundwater depletion.
The resource demands of modern digital infrastructure are staggering. According to a November 2025 report from the Brookings Institution, while an average facility uses around 300,000 gallons of water daily, large hyperscale data centres can consume an estimated 5 million gallons( approximately 19 million litres) every single day. That is equivalent to the daily water demand of a town of 50,000 residents.
Consequently, operators can no longer break ground based on power availability alone. Municipal water capacities, local watershed health and long-term climate projections are dictating where new campuses can be viably sustained. Building a facility in a waterstressed region without a rigorous hydrological strategy now risks stranded capacity, regulatory roadblocks and severe reputational damage. To address these geographic constraints, operators are conducting detailed watershed analyses before acquiring land. This involves mapping local aquifers, assessing the reliability of municipal wastewater treatment plants for greywater use and modelling the impact of projected droughts on water tariffs.
