Data centre water records

Data centre water records, with the disclosure basis stated on every one.

8 records
AWS Northern Virginia region

The largest concentration of data centre capacity in the world. AWS reports a company-level water usage effectiveness and uses reclaimed water at several Virginia sites.

Google Council Bluffs

One of Google’s largest campuses. Google publishes site-level water withdrawal and consumption annually, making its US sites among the most transparently reported data centres anywhere.

Google The Dalles

Subject of a multi-year public records dispute over disclosure of its municipal water use, resolved when the figures were released — an early landmark in data centre water transparency.

Microsoft Des Moines

Reported in connection with large-scale AI model training, and cited in academic work estimating the water footprint of training runs.

Microsoft Ireland campus

Ireland’s temperate climate permits extensive free cooling, so water use is low relative to warm-climate sites. Grid electricity capacity, rather than water, is the binding constraint on D…

Google St Ghislain

Designed to use treated water from an industrial canal rather than drinking water — one of the clearest examples of siting cooling water demand away from potable supply.

Data centre cluster, Aragón

A rapidly growing cluster in a water-stressed region of Spain, where planning and environmental documentation is the principal public source of water demand information.

Meta Clonee

Meta publishes facility-level water figures and reports a relatively low water usage effectiveness at temperate sites.

Hydrionis is an evidence-led water intelligence resource. Every figure carries its source, its method and its licence. Where Hydrionis does not hold a value, it says so rather than estimating one.

Hydrionis presents scientific and regulatory information for general reference. It is not medical, legal or engineering advice. Drinking water standards are jurisdictional: a limit applies only where it was made. For a concern about the water at your own property, contact your water supplier or the relevant regulator.

Data is drawn from public and open sources under their respective licences. Contains public sector information licensed under the Open Government Licence v3.0. Contains modified Copernicus service information. Country outlines derived from Natural Earth (public domain).
