As demand for AI continues to accelerate, the data centre industry faces an increasingly important challenge: water. While attention often focuses on power availability and grid capacity, water shortages are emerging as a key factor that could influence where new data centres are built, how they operate and the technologies they adopt.

For employers, investors and professionals working in data centres, the shift towards more water-efficient cooling methods is creating new opportunities and changing skills requirements across the sector.

Why water is becoming a critical issue

As AI adoption accelerates, water is becoming a growing concern for the data centre sector. Many data centres rely on significant volumes of water for cooling, and increasing demand is putting pressure on already stretched resources.

In the UK, the issue is particularly relevant. Research from Global Action Plan found that 84% of proposed UK data centres are planned in areas that are already water stressed or expected to become water stressed by 2040. The report also states that a single hyperscale data centre can consume enough water each day to meet the needs of around 10,000 people. [globalacti…lan.org.uk], [watermagazine.co.uk]

At the same time, the UK faces a projected water supply shortfall in the coming decades, creating a challenge for policymakers and developers seeking to support continued AI and digital infrastructure growth. [assets.pub…ice.gov.uk], [globalacti…lan.org.uk]

The impact on data centre development

Water availability is becoming an important consideration alongside power and connectivity when planning new data centre developments.

Projects in water-stressed areas are facing increased scrutiny from regulators, local communities and environmental groups. Developers are under growing pressure to demonstrate sustainable water management and minimise their impact on local resources.

As a result, operators are increasingly investing in technologies that can reduce water consumption while supporting the growing demands of AI infrastructure.

The rise of liquid direct-to-chip cooling

One of the technologies gaining significant attention is liquid direct-to-chip (DTC) cooling.

Rather than relying solely on air, DTC cooling delivers coolant directly to high-heat components such as GPUs and CPUs, making it far more effective at managing the intense heat generated by AI workloads. Industry experts view the technology as an important step in supporting higher-density computing while improving efficiency. [blog.se.com], [ashb.com]

Alongside DTC cooling, operators are exploring closed-loop systems, immersion cooling and the use of treated wastewater to reduce reliance on fresh water supplies. Some liquid-cooled designs can significantly reduce water consumption compared with traditional cooling methods. [blogs.nvidia.com]

What this means for employers and candidates

The transition towards advanced cooling technologies is creating demand for specialist talent across engineering, design, construction and operations.

Employers are increasingly seeking professionals with experience in:

  • Data centre mechanical and electrical engineering
  • Thermal management and cooling systems
  • HVAC and fluid systems design
  • Sustainability and environmental compliance
  • Commissioning and facilities operations
  • AI infrastructure deployment

For candidates, this represents an opportunity to build expertise in one of the fastest-growing areas of digital infrastructure.

Looking ahead

The future growth of AI depends on more than computing power. Access to energy, land and water will influence where and how data centres are developed in the years ahead.

The industry’s response is already underway, with liquid direct-to-chip cooling and other water-efficient technologies helping to support growth while reducing environmental impact. For businesses and professionals across the sector, understanding these changes will be essential as the next phase of data centre development takes shape.
