The Water Crisis Behind AI: Data Center Expansion Strains India’s Groundwater

What Happened

India is undergoing a massive expansion of its digital infrastructure, with data center capacity growing from 375MW in 2020 to a projected 13.56 GW by 2031-32. This growth, driven by the rise of artificial intelligence and digital services, carries a significant and often undisclosed environmental cost. Research from the University of California, Riverside, indicates that a single interaction with an AI like ChatGPT, consisting of 20 to 50 exchanges, consumes approximately half a liter of water. Globally, the electricity used by data centers resulted in a water footprint of 4.5 trillion liters in 2025, a figure expected to rise to 9.3 trillion liters by 2030.

Background

The expansion is supported by aggressive state policies. Andhra Pradesh’s Data Centre Policy 4.0 provides 100% GST reimbursements and stamp duty exemptions for large projects, while Gujarat aims to attract ₹6 lakh crore in investment to reach a 7.5 GW capacity. Uttar Pradesh is also targeting over 2GW of additional capacity. Major corporate entities are leading these developments, including Google’s 1GW hub in Vishakapatnam and Meta’s partnership with Reliance Industries for an AI-enabled facility in Jamnagar.

Why It Matters

The environmental strain is particularly acute in regions already facing water scarcity. The Central Ground Water Board (CGWB) reports that India's national groundwater extraction rate is 60.47%, with over 11% of assessment units classified as over-exploited. In Gautam Buddha Nagar, Uttar Pradesh, which hosts 17 data centers, the extraction rate is 104.79%, meaning the region consumes more water than is naturally replenished. Similar pressures are noted in Hyderabad, which is officially designated as over-exploited. Unlike standard industrial sites, data centers often cluster, potentially draining local aquifers and relying on tanker water sourced from across urban areas.

Key Facts

• A 20 to 50 exchange conversation with ChatGPT consumes about 0.5 liters of water.
• Data center capacity in India is projected to increase from 375MW in 2020 to 13.56 GW by 2031-32.
• The 4.5 trillion liters consumed by data centers in 2025 is equivalent to nearly nine years of Chennai's water needs.
• Public opposition has emerged, with protests against projects by Amazon in Maharashtra and Google/AdaniConneX in Andhra Pradesh.
• Experts suggest that India's hot and humid climate may increase cooling demands, though final water usage depends on specific cooling technologies.

What Happens Next

As the water footprint of the digital economy grows, experts are calling for mandatory transparency regarding monthly water use and the sources utilized, such as potable or groundwater. There is a push for stricter permitting in water-stressed areas and a transition toward using reclaimed water to mitigate the impact of massive AI hubs on local ecosystems.
