Data Centers Decoded: Myth #4

Key Takeaways

• Not all data centers use the same cooling technology or the same amount of water.
• Cooling strategies are selected based on climate, operational needs, and available local resources.
• Developers and technology providers continue to invest in water-efficient cooling technologies, including direct air cooling, closed-loop cooling, liquid cooling, and hybrid systems.
• A single water-use number rarely tells the whole story without understanding the project's design and operating conditions.
• Thoughtful planning helps balance operational performance with responsible water management.

MYTH: Data centers consume enormous amounts of water.

TRUTH: Many data centers use less water than a golf course.

It's not the comparison most people expect—and that's exactly why context matters.

So, how much water does a data center actually use?

It depends.

One of the biggest misconceptions is assuming every data center uses the same cooling approach. Today's facilities use a variety of cooling systems, including direct air cooling, closed-loop cooling, liquid cooling, and hybrid designs. Each is selected based on the local climate, operational needs, and available resources. As water scarcity concerns have grown, developers and technology providers have continued investing in these technologies to improve water efficiency while supporting the increasing demands of modern computing.

That's why a single water-use number rarely tells the whole story.

A more meaningful conversation begins with questions like:

• What cooling technology is being used?
• Why was that approach selected for this location?
• How does it balance operational performance with responsible water management?

Understanding those decisions provides a much clearer picture of a project's environmental impact than a headline ever could.

Thoughtful design isn't about applying the same solution everywhere. It's about selecting the right solution for the right site.
