When temperatures rise, data centres don’t just consume more electricity - many also need more water.
As parts of the UK face temperatures in the mid-to-high 30s, almost three-quarters of England is now officially in drought.
That creates an important question:
How can we keep our digital infrastructure cool without placing even greater pressure on limited water supplies?
Many traditional data centres use evaporative or water-assisted cooling to remove heat from servers. During a heatwave, cooling demand can increase at precisely the time when water resources are under the greatest strain.
It’s an uncomfortable contradiction - businesses need reliable digital services, while communities, agriculture and the environment need us to conserve water.
During periods of extreme heat, data centre operators should be closely monitoring:
✅ Equipment and facility temperatures
✅ Water availability and consumption
✅ Grid, UPS and backup power capacity
✅ Cooling efficiency and humidity levels
✅ Alerts, redundancy and failover systems
This is where liquid immersion cooling offers a different approach.
By submerging servers and storage equipment in a non-conductive dielectric fluid, heat is removed directly from the components. This helps maintain stable operating temperatures while significantly reducing reliance on energy - and water-intensive cooling systems.
At PeaSoup, single-phase liquid immersion cooling is already part of how we deliver sovereign, sustainable and resilient UK cloud services.
Data centre resilience can no longer be measured by uptime alone. We also need to consider how responsibly our infrastructure uses energy and water - especially as heatwaves and droughts become more common.
