How much water do data centres really use in the UK?

Our Take

Credit to Sky News technology correspondent Rowland Manthorpe for doing the unglamorous work of actually tracking down Environment Agency and MOSL numbers instead of repeating industry talking points. The UK conversation he's covering — how much water data centers really use, and how a facility can be technically "waterless" on site while still leaning on power and water elsewhere in the chain — is the exact same shell game playing out at county commission meetings from Georgia to Arizona.

The pattern Sky News found in England will sound familiar to anyone following American permitting fights: aggregate industry numbers look small next to agriculture or households, until you zoom into the specific watershed or utility district where a single campus lands. "Waterless" cooling systems often shift the burden to the power plant generating the electricity that runs the chillers, or to a different water source upstream — a distinction that rarely makes it into the press release announcing a new facility.

That's the gap GridWatch exists to close on this side of the Atlantic — pushing past the headline claims to find the actual permits, water withdrawal figures, and tax deals tied to specific U.S. sites.
