Data center operators are increasingly confronting the challenge of water scarcity as they expand their infrastructure. A recent Gallup poll found that seven out of 10 Americans oppose data center development, with water scarcity cited as the top resource concern. Companies are now scrambling to address these concerns by adopting new cooling strategies and committing to water conservation efforts. Water is essential for cooling server racks, which generate significant heat, and evaporative cooling is a common method that uses large amounts of water. This has raised concerns about the environmental impact and sustainability of such practices. Google, Microsoft, and OpenAI are among the tech giants adjusting their approaches to reduce water use, with Google rolling out specific commitments to communities hosting its data centers.

Google has pledged to replenish more freshwater than it consumes in certain regions through investments in local water projects. The company is also scaling up the use of reclaimed and recycled water and plans to disclose annual water use in its data centers. Google’s approach includes a data-driven framework to determine the best cooling designs for local watersheds. Ben Townsend, Google’s global head of infrastructure and sustainability, emphasized that a one-size-fits-all strategy for cooling is not viable, as water availability varies by region. The company has been conducting detailed hydrologic assessments of its sites for the past four years to inform its cooling strategies. (Source: arstechnica)

Lawrence Berkeley National Laboratory predicted that hyperscale data centers could consume up to 33 billion gallons of water by 2030 if they relied heavily on evaporative cooling. This usage is comparable to other water-intensive industries like agriculture or oil and gas. However, the risk is particularly acute in regions experiencing water scarcity, especially during the summer when cooling demands peak. Shaolei Ren, a professor of engineering at UC Riverside, noted that water is a highly local and regional issue that requires careful management. Despite efforts to reduce water use, tech companies continue to face challenges, and these issues could impact their business operations in the long term. (Source: arstechnica)
