The GCC's next data challenge is water

For years, energy has dominated the data centre sustainability conversation. In the GCC, however, another constraint is becoming increasingly important: water.

As hyperscale and AI infrastructure expands across the region, cooling systems are no longer being judged solely on performance and efficiency. Increasingly, they are being evaluated on how sustainably they operate in some of the world’s most climate-challenging environments.

This matters because the GCC is entering a period of rapid digital infrastructure growth. Across the UAE and Saudi Arabia, sovereign AI strategies, cloud expansion, and hyperscale investment are accelerating demand for high-density data centres at unprecedented scale.

At the same time, the region’s climate creates operational realities that cannot be ignored. In the Gulf, cooling is fundamental to infrastructure reliability.

That is why water is moving higher up the agenda.

The GCC has always had to think carefully about resource management. As data centre development accelerates, water usage is becoming a far more visible part of wider sustainability and infrastructure discussions.

Governments across the region are placing greater emphasis on sustainability goals alongside digital growth ambitions. Investors and hyperscalers are also asking more detailed questions around environmental performance, resource usage, and infrastructure viability.

One trend increasingly visible across GCC projects is that conversations around water are happening much earlier in the design process. In recent hyperscale and AI developments, clients are placing greater emphasis on how facilities will manage cooling demand during peak summer conditions.

This is becoming more important as AI workloads continue to increase cooling requirements. Higher-density environments generate significantly more heat, placing additional pressure on infrastructure and, in some cases, increasing water consumption. The challenge is not simply technical. It is strategic.

Facilities being planned today are expected to operate for decades. Decisions made early in the design phase will influence efficiency, sustainability outcomes, and operational stability well into the future.

Cooling sits at the centre of this issue because every approach involves trade-offs. Some technologies reduce energy consumption but require greater water usage. Others minimise water dependency while increasing energy demand or operational complexity.

In regions with milder climates, some of these decisions are easier to balance. In the Gulf, where facilities must maintain performance in extreme temperatures, those trade-offs become far more significant.

AI infrastructure is accelerating this challenge further. As rack densities increase and compute environments become more intensive, traditional assumptions around cooling are being tested, forcing the industry to rethink how facilities are designed and operated.

In the GCC, this is no longer simply a question of efficiency. It is becoming a broader issue of resilience, sustainability, and practicality.

That includes considering water availability alongside energy performance, exploring opportunities for reuse and recycling, and evaluating alternative cooling technologies where appropriate.

It also requires recognising that design philosophies developed for Europe or North America may not translate directly to GCC operating conditions. Climate realities, infrastructure availability, and sustainability expectations all shape what effective data centre design looks like in the region.

Across industry discussions, there is growing recognition that cooling solutions need to reflect regional conditions rather than imported assumptions. Water strategy is also beginning to influence how projects are perceived across the market.

Site selection and planning approvals are becoming more closely linked to sustainability considerations. Facilities able to demonstrate a credible approach to water management and cooling efficiency may encounter fewer challenges as scrutiny increases.

At the same time, hyperscalers and investors are becoming more sophisticated in how they evaluate infrastructure risk. Sustainability conversations are moving beyond high-level carbon targets into more detailed assessments of operational performance and resource dependency.

Water scarcity is not simply an environmental issue. In some markets, it may become an operational risk capable of affecting infrastructure performance over the lifetime of a facility. Organisations that recognise this shift early will be better positioned to scale sustainably as the market matures.

There is no universal solution. Every cooling approach involves compromise between water consumption, energy efficiency, complexity, cost, and resilience.

Some technologies will be better suited to specific environments than others. What matters is developing an approach aligned to local operating conditions, infrastructure priorities, and practical long-term requirements rather than pursuing a perfect theoretical solution.

The most effective strategies are often the most balanced.

Over the next five to ten years, water efficiency is likely to become a major differentiator between data centre developments across the GCC. As AI adoption accelerates, the industry will place greater focus on solutions that balance resilience, sustainability, and operational practicality.

The scale of growth across the region means the decisions being made today will shape infrastructure performance for decades.

In this environment, water is moving from a secondary sustainability consideration to a defining factor in how facilities are designed, operated, and scaled. Organisations that recognise this shift, and take a more thoughtful approach to cooling, sustainability, and resilience, will be better positioned to adapt, build trust, and scale with confidence over the long term.
