India's rapid data center expansion, projected to reach 358 billion litres of water usage by 2030, highlights potential operational and regulatory risks. Investors should monitor how operators manage water consumption and environmental disclosures as the sector grows.
What Happened
India is seeing a major rise in data center construction as digital demand increases. With committed investments reportedly exceeding $156 billion, the country is rapidly building the infrastructure needed for data storage. However, this growth has brought attention to the sector’s high reliance on water for cooling. Data centers act like power plants for computation, generating massive amounts of heat that require constant cooling systems. Current projections indicate that the sector's water consumption could rise from an estimated 150 billion litres in 2024 to 358 billion litres by 2030.
Why This Matters For Investors
For investors, the primary concern lies in the link between resource sustainability and long-term operational costs. Data centers are often located in urban regions that are already experiencing water stress. While the sector currently benefits from significant investment and growth, the lack of mandatory national regulations regarding water usage and environmental impact could lead to future regulatory changes. If the government introduces strict rules on water consumption, operational costs for data center operators could increase. Additionally, companies with weak environmental, social, and governance (ESG) practices may face reputational challenges as global standards for digital infrastructure tighten.
The Operational Challenge
Data centers rely on Power Usage Efficiency (PUE) and Water Usage Effectiveness (WUE) to measure how efficiently they use electricity and water. Currently, cooling systems consume significant water to manage server temperatures, especially in India's warmer climate. Because water is often inexpensive in municipal settings, operators have historically viewed water risk as a low priority. However, relying on scarce municipal water supplies in regions prone to shortages poses a risk to business continuity. The industry is beginning to explore alternatives, such as using treated sewage water for cooling, but this requires substantial long-term capital spending on infrastructure.
The Regulatory Landscape
There is currently a gap in mandatory environmental disclosures for data centers in India. Most operations are not required to report their water or energy usage in detail. This transparency gap makes it difficult for investors to fully assess which companies are building sustainable infrastructure and which ones remain vulnerable to future regulations. Experts suggest that mandatory impact assessments and transparent water usage reporting could become a standard requirement in the coming years. Operators who proactively invest in water-saving technologies may be better positioned to adapt to these potential changes.
What Investors Should Track
Investors monitoring the data center space should look beyond top-line revenue growth and capital expenditure. Important indicators include the operator's strategy for water recycling and the adoption of energy-efficient cooling technologies. It is also important to consider the geographic concentration of a company's data centers; facilities located in regions with severe water scarcity may face higher risks than those in water-abundant areas. Finally, tracking management commentary on environmental targets and voluntary water usage disclosures can provide insight into a company's preparedness for stricter future regulations.
