Data Centers and Water Use Explained
How AI data centers impact local water resources without federal data.
In brief
How AI data centers impact local water resources without federal data. AI data centers use significant water but federal data is lacking; local context matters most. Originally reported by USAFacts.
Quick answers
- Why little data on data centers and water?
- Federal data on data center water use is scarce and not centralized, with local projects offering limited insights.
- Why do people care about data centers and water?
- Water scarcity affects communities, and data centers demand water, raising concerns about local availability.
- How data centers use water?
- Data centers may use water for cooling equipment via open-loop or closed-loop systems, with varying water needs.
- What happens next?
- Local water utilities and communities must assess data center impacts on water resources and infrastructure.
- What is the key takeaway from Data Centers and Water Use Explained?
- AI data centers use significant water but federal data is lacking; local context matters most.
Why little data on data centers and water?
Federal data on data center water use is scarce and not centralized, with local projects offering limited insights.
Why do people care about data centers and water?
Water scarcity affects communities, and data centers demand water, raising concerns about local availability.
How data centers use water?
Data centers may use water for cooling equipment via open-loop or closed-loop systems, with varying water needs.
Open-loop vs. closed-loop cooling
Open-loop systems require continuous water supply due to evaporation, while closed-loop systems reuse water with minimal additional intake.
Water use in 2023
Data centers used 17 billion gallons of water in 2023, equivalent to 389,700 people's annual water use.
AI data centers and water demand
AI data centers are large and use liquid-cooled systems, increasing water demand but exact usage remains unclear.
Botetourt County data center
A data center in Botetourt County reserves 2 million gallons per day of water, with actual use likely lower.
Water source matters
Data centers often rely on public water systems, which can affect local water availability and quality.
Wastewater disposal concerns
Data centers generate wastewater that may require treatment or pose risks to local water quality.
Key questions for local impact
Local water availability, data center size, cooling technology, and water source determine community impact.
Water is local
Water regulation occurs at the state level, not federal, making local context critical for data center impacts.
AI spending and data centers
AI spending accounted for 30% and 11% of GDP growth in Q2 and Q3 of 2025, with $7.5 billion invested in data centers in August 2026.
What happens next?
Local water utilities and communities must assess data center impacts on water resources and infrastructure.
The main idea
AI data centers use significant water but federal data is lacking; local context matters most.
