India’s Data Centre Push Is Outpacing Its Water Governance
India’s data centre push is accelerating. Water governance isn’t keeping pace. This piece looks at how data centres are being planned as digital infrastructure, while their water footprint remains largely under-examined and why that gap matters as capacity scales.
India is moving quickly to position itself as a global data centre hub. The drivers are clear: data localisation, rapid growth in cloud services, and the integration of AI across sectors. Large investments from global technology firms and Indian conglomerates signal confidence in this direction.
What remains under-examined is water.
In most policy discussions, data centres are framed as digital infrastructure. The focus is on land, power availability, connectivity, and fiscal incentives. Water is treated as an operational input that can be arranged later. That assumption deserves scrutiny.
Growth without guardrails
India generates approximately 20% of the world’s data, but hosts only about 3% of global data centre capacity. Closing this gap has become a strategic objective. Capacity is projected to expand sharply over the next few years, with estimates indicating a substantial increase in both capital investment and installed power capacity by the end of the decade.
States such as Andhra Pradesh, Uttar Pradesh, Karnataka, Telangana, and Gujarat are actively competing to attract these investments. Dedicated state data centre policies offer land support, power infrastructure, and long-term tax exemptions. At the national level, the Ministry of Electronics and IT is drafting a broader framework to support the sector.
From an investor’s perspective, the signal is strong and coherent.
From a water governance perspective, it is fragmented.
The water footprint we rarely quantify
A widely cited estimate suggests that a 1 MW data centre using water-based cooling can consume around 26 million litres of water annually. A mid-sized 30 MW facility would therefore require roughly 780 million litres every year.
India’s total data centre water demand is expected to more than double over this decade. This expansion is unfolding in a country that supports nearly one-fifth of the global population with only a small share of global freshwater resources.
Despite this, water rarely appears as a limiting factor in approval processes. Power sourcing is examined in detail. Water is often assumed to be available through a combination of groundwater, tanker trucks, surface water, or treated wastewater.
State policies and the missing specifics
State data centre policies generally encourage the use of treated or recycled water. Few, however, clearly define enforceable requirements. Questions often left unanswered include:
What proportion of cooling water must come from non-potable sources?
How is cumulative water demand assessed at the city or basin level?
What disclosure is required on withdrawal, consumption, and discharge?
Without such clarity, facilities may remain compliant individually while collectively pushing local water systems beyond sustainable limits.
Why offsets cannot replace regulation
Some companies have adopted “water offsetting” strategies, investing in lake restoration or recharge projects to compensate for their use elsewhere. These initiatives can be beneficial, but they do not address the core issue.
Water is inherently local. Replenishment in one location does not prevent depletion where extraction is concentrated. Treating offsets as a balancing mechanism risks turning a physical constraint into an accounting exercise.
The transparency gap
Perhaps the most significant gap is public information. Data on water consumption, discharge quality, and long-term impacts of data centres is rarely accessible. This raises a fundamental governance concern: if water use is not tracked transparently, intervention is likely to occur only after impacts are felt.
India’s data centre ambition is not misplaced. But ambition without water governance creates fragility rather than resilience.
