Data Center Operators Are Trying to Fix Their Water Use Problems

Key Points:

• SpaceX updated its IPO filing to acknowledge that water scarcity, regulations, and drought could limit data center development, highlighting growing concerns about water use in the tech industry.
• Data centers use large amounts of water primarily for evaporative cooling, which helps reduce energy costs but creates significant water footprints; for example, Google's Iowa facility used over 1 billion gallons in 2024.
• Some tech companies like Microsoft, OpenAI, and Oracle are moving away from evaporative cooling to conserve water, while Google is focusing on tailored water management strategies including replenishment pledges and increased use of recycled water.
• Experts note that water availability varies regionally, making a one-size-fits-all cooling solution impractical; evaporative cooling can reduce power demand but may increase water use in water-scarce areas, presenting complex trade-offs.
• Despite efforts to reduce water consumption, tech companies still face challenges and public resistance, which may impact future data center projects, emphasizing the need for smarter designs and stronger regulation.
