UK's water supply insufficient for future datacentre expansion, warns trade body

Insufficient Water Supply for Datacentres

Water UK has issued a stern warning regarding the UK's ability to support future datacentre growth due to inadequate water resources. The trade body emphasizes that current government policies, particularly those relating to AI growth, do not mention water usage or requirements for datacentres, which are essential for managing heat generated by servers.

Concerns Raised by Water UK

The briefing provided to MPs by Water UK states that existing water forecasts are flawed and fail to include the expected demands from datacentres. Critics argue that there is a dangerous assumption that the water supply will automatically meet economic needs, which is not justifiable given current trends.

Current Challenges in Water Management

The UK is already experiencing significant water challenges, including hosepipe bans in regions with high datacentre concentrations. Water UK notes that new datacentre developments may face insurmountable obstacles without changes to current policies, particularly given the historical context of water shortages outlined in previous reports.

Future Implications for Datacentres

If datacentres continue to be built in water-stressed areas without addressing water supply issues, it could impede the growth of the tech sector in the UK. Current solutions involve long-term investments and planning in water infrastructure, which could delay or limit potential datacentre projects.

Critique of Water Company Management

In response to Water UK's statements, Greenpeace highlighted that water companies are wastefully allowing leakage, contributing significantly to water supply issues. Despite reported reductions in leakage rates, the broader implications for water security amid growing demand remain a critical concern.
