Why it matters now
Data centers, particularly hyperscale facilities, require significant amounts of water for cooling, especially in regions with warmer climates or high-density computing. As water scarcity becomes a more pressing global issue, public scrutiny and regulatory oversight of industrial water consumption are intensifying. This is leading to stricter permitting requirements, longer approval processes, and potential operational constraints for data center developers. Understanding the specific geographic areas and regulatory environments where water usage poses the highest permitting risk is crucial for ensuring the sustainable and timely development of essential digital infrastructure.
Who is exposed
Hyperscale data centers face potential delays and increased costs in site development due to stringent water use permitting. Colocation providers may see limitations on expansion in water-stressed regions, impacting their service offerings. Cloud computing companies are exposed to operational risks if their underlying data center infrastructure faces water-related disruptions. This also affects local communities, environmental agencies, and the broader real estate market for industrial sites.
Most relevant for: Chief Sustainability Officer, Head of Infrastructure, General Counsel

Questions
Why do data centers use so much water?
Data centers generate substantial heat from their servers and equipment, which needs to be dissipated to maintain optimal operating temperatures. Water is a highly effective and cost-efficient medium for cooling, particularly in evaporative cooling systems, which are common in many large-scale data center facilities to manage heat loads.
What are the alternatives to water cooling?
Alternatives include air-side economizers, direct-to-chip liquid cooling, and immersion cooling. These methods aim to reduce or eliminate water consumption. While some alternatives are highly effective, they often involve higher initial capital costs or different operational complexities compared to traditional water-based cooling systems.
How does water scarcity affect data center development?
Water scarcity can lead to increased scrutiny from regulators and local communities, resulting in more stringent permitting requirements, longer approval processes, and potential restrictions on new data center developments. It can also drive up operational costs due to higher water prices or the need to invest in advanced water recycling technologies.
