California Data Centers Expand into Water-Stressed Communities
New report warns of intersecting water scarcity and social vulnerability
A landmark study from think tank Next 10 reveals that California's rapidly growing data center industry is increasingly moving into regions facing severe water scarcity and socioeconomic vulnerability. The shift from urban tech hubs to groundwater-dependent towns raises urgent questions about long-term sustainability and environmental justice as AI demand accelerates.
Key details
The report, "The Intersection of Data Center Development, Water Availability, and Environmental Justice in California," authored by Santa Clara University researchers, is the first comprehensive analysis of the state's operating and planned facilities through a water and equity lens. It identifies the Central Valley and Imperial Valley as primary areas where water scarcity and social vulnerability most acutely overlap with new data center developments.
Many of these newer, large-scale facilities are being sited away from traditional tech hubs like Silicon Valley, moving instead into regions that rely heavily on shared groundwater basins or imported water. These areas often lack the diversified water supplies and financial flexibility of larger urban systems, making them particularly susceptible to the cumulative pressure of water-intensive cooling requirements. The researchers examined five specific case studies—three existing and two planned—to highlight how these facilities can reduce regional drought resilience.
Why this matters
This story highlights a critical friction point in the AI boom: the physical resource requirements of digital infrastructure. As data centers scale to support AI training and inference, their water consumption can strain local supplies, potentially competing with agriculture, ecosystems, and residential needs. The lack of transparency regarding exact water usage figures makes it difficult for local policymakers to plan for long-term water security or evaluate community tradeoffs.
Context
California is at the forefront of both the AI revolution and the climate-driven water crisis. While the state has ambitious goals for digital leadership, it also faces persistent groundwater depletion and increasingly volatile surface water availability. This report follows a trend of heightened scrutiny on data center resources, similar to recent legislative actions in Florida and North Carolina aimed at protecting ratepayers and local infrastructure from the impacts of hyperscale expansion.
Risks and open questions
A major risk identified is the "fundamental lack of transparency" regarding how much water data centers actually consume. Without granular data on whether facilities use potable water, recycled water, or groundwater, it is nearly impossible to conduct accurate environmental reviews. There is also the question of whether efficiency claims made by operators translate into actual resource savings at the local level.
What happens next
The report concludes with a call for stronger safeguards, consistent environmental reviews, and integrated planning that considers water, energy, and community impacts together. Moving forward, California policymakers may face pressure to mandate better data disclosure from data center operators to align the industry's growth with the state's broader environmental justice and sustainability goals.
