When it comes to total water use, AI data centers are a drop in the bucket
Summary
A new report from Amazon, supported by data from Google, Microsoft, and Meta, indicates that while AI data centers consume billions of gallons of water annually, their aggregate usage remains a small fraction of overall national and global water consumption. Amazon claims its data centers withdrew about 2.5 billion gallons globally in 2025, a figure dwarfed by the 117 trillion gallons withdrawn in the US alone in 2015, or the 3.3 trillion gallons used for US lawns. However, despite the relatively low global impact, individual data centers can severely strain local water supplies, with examples like a Meta facility using 10% of Newton County, Georgia's water. Tech companies are responding by implementing efficiency measures, such as Amazon running data centers hotter, and funding water stewardship projects, like Google's 165 initiatives aiming to replenish 19 billion gallons annually by 2030.
Key takeaway
For urban planners and local government officials evaluating new data center proposals, recognize that while global water impact is minimal, local water infrastructure faces significant strain. Prioritize detailed assessments of regional water availability and scarcity before approving projects. Your due diligence should include requiring data centers to commit to water-efficient cooling and local replenishment initiatives to ensure sustainable community resource management.
Key insights
AI data center water use is globally minor but locally significant, prompting corporate stewardship.
Principles
- Aggregate data center water use is negligible globally.
- Local water resources face disproportionate strain.
- Corporate water stewardship initiatives are increasing.
Method
