Water Constraints Emerge as Critical Risk for Data Centre Expansion, Veolia Warns

The rapid expansion of data centres, driven by artificial intelligence, cloud computing, and digital services, is placing growing pressure on global water resources. According to Veolia, water availability is emerging as a critical factor that could shape where and how future data centres are built.

While much of the sustainability debate around data centres has focused on energy consumption and carbon emissions, water usage is becoming an equally important concern. Cooling systems in data centres often rely heavily on water, particularly in facilities using evaporative cooling technologies. As a result, regions already facing water stress may struggle to accommodate new infrastructure without exacerbating local resource constraints.

Rising Demand Meets Finite Water Resources

Veolia highlights that water scarcity is no longer a distant risk but a present and growing challenge. Climate change, population growth, and industrial demand are intensifying competition for water resources. In this context, data centres are increasingly scrutinized for their water footprint, particularly in areas prone to drought or limited water supply.

The scale of the issue is significant. Hyperscale data centres, which support large cloud providers and AI workloads, can consume millions of litres of water per day depending on their design and location. As demand for computing power accelerates, particularly with the rise of generative AI, the cumulative impact on water systems is expected to increase substantially.

Site Selection and Community Pressures Intensify

Water availability is already influencing where data centres are being built. Developers are beginning to prioritize locations with reliable water access, cooler climates, or opportunities to use alternative cooling methods.

In some cases, projects have faced delays or local opposition due to concerns over water use. This reflects a broader shift in how communities and regulators evaluate large-scale digital infrastructure investments. Water, once a secondary consideration, is now becoming a decisive factor alongside energy supply and land availability.

Technology Pathways to Reduce Water Dependency

Addressing water challenges will require a combination of technological innovation and improved resource management. Veolia points to several solutions that are gaining traction across the sector.

Closed-loop water systems allow facilities to recycle and reuse water internally, significantly reducing overall consumption. Advanced treatment technologies can also enable the use of non-potable water sources, such as wastewater or industrial effluent, for cooling.

Another key approach is the adoption of air-based or hybrid cooling systems, which reduce reliance on water. Although these systems may involve higher energy use or upfront costs, they offer a more viable solution in water-constrained regions. Operators are increasingly evaluating these trade-offs as part of broader sustainability strategies.

Expanding Scope of Corporate Sustainability Strategies

The growing focus on water reflects a wider shift in corporate climate action. Companies are moving beyond carbon metrics to address interconnected environmental challenges, including water, biodiversity, and land use.

For data centre operators, this means integrating water management into environmental, social, and governance frameworks. Investors and customers are also placing greater emphasis on transparency and accountability, driving demand for more detailed reporting on water consumption and efficiency measures.

Regulatory and Market Implications

Regulatory frameworks are evolving in response to increasing water stress. In some regions, governments are introducing stricter requirements for water use, particularly for large industrial facilities. This includes enhanced disclosure obligations and efficiency standards.

For operators, this may translate into higher compliance costs and more complex project approvals. At the same time, it creates opportunities for companies that can demonstrate strong water stewardship practices.

For service providers like Veolia, the shift opens up new markets for water management solutions, including recycling, treatment, and optimization technologies tailored to data centre needs.

Strategic Implications for Digital Infrastructure Growth

The intersection of water and digital infrastructure raises important questions for long-term planning. As countries seek to expand their digital economies while managing environmental constraints, integrated approaches to energy and water systems will become increasingly important.

Water is now emerging as a limiting factor in data centre growth, alongside energy availability and grid capacity. Companies that proactively address water risks through design, technology, and location strategy are likely to be better positioned in an increasingly resource-constrained environment.

Conclusion

The sustainability of digital infrastructure is entering a new phase, where water management is as critical as energy efficiency and emissions reduction. Veolia’s analysis underscores that water scarcity is no longer a peripheral issue but a central challenge for the data centre sector.

As demand for digital services continues to grow, the ability to balance technological expansion with responsible resource use will be essential. Water, once overlooked in the data centre sustainability equation, is now firmly at the forefront of industry strategy.
