Hydrionis for technology and data centres

What you can answer here

What is the defensible water-stress figure for this location?

National water stress with its full definition, its source, its reporting year and its comparability constraints attached — the things a disclosure reviewer asks for.

Where it stops: Water stress is published nationally. Presenting a national figure as a site figure is the most common error in water disclosure, and Hydrionis will not do it for you.

How much water does a data centre actually use?

Hydrionis holds the sector context and the published reference material rather than facility-level consumption, which is very rarely disclosed.

Where it stops: Facility-level water use is not open data. Anyone offering it at scale is estimating, and Hydrionis does not publish estimates as observations.

Key measures

Full dictionary →
MeasureDefinitionUnit
Water stressFreshwater withdrawal as a percentage of available renewable freshwater resources, after accounting for environmental flow requirements.
A national figure averages over basins that can be individually far more stressed. Values above 100% mean withdrawal exceeds renewable supply, which is only possible by depleting groundwater, desalinating, or importing water.
%
Renewable freshwater per personTotal renewable freshwater resources divided by population.
A per-capita average conceals seasonal and regional distribution entirely. A country can be water-rich on this measure and still have cities that run short.
m³/person/yr
Industrial share of withdrawalPercentage of total freshwater withdrawal used by industry, including energy cooling.
Countries differ in whether thermoelectric cooling is counted as industrial withdrawal. Where it is included, the industrial share can exceed 50% in countries with large freshwater-cooled power fleets, which reflects cooling arrangements rather than manufacturing intensity.
