Verdict: India's $35+ billion data center buildout is splitting into two models: Microsoft's Hyderabad region, which launched August 6, 2026, with zero-water air-cooled chillers to sidestep the resource conflict, and Google's $15 billion Visakhapatnam hub, which faces multiple court cases over water scarcity and proximity to a wildlife sanctuary. The divide proves that in water-stressed India, cooling technology choice is no longer an engineering footnote — it decides whether a hyperscale project makes it to operation or stalls in litigation.

What did Microsoft launch in Hyderabad in August 2026?
Microsoft went live with its India South Central cloud region in Hyderabad on August 6, 2026 — its fourth India cloud region and its largest in the country (Microsoft Source Asia, August 2026). The region comprises three availability zones built to India's seismic-zone and regulatory requirements, joining existing regions in Pune (Central India), Chennai (South India), and Mumbai (West India).
Early customers include the Adani Group, HDFC Bank, and Bajaj Finance, all positioning for data residency, AI workload scaling, and disaster-recovery redundancy. HDFC Bank specifically called it a "dedicated DR region" complementing its Central India footprint.
The investment behind this region is $20.5 billion — a combination of two prior announcements: $3 billion in January 2025 and $17.5 billion in December 2025 covering the 2026–2029 period (Microsoft, January 2025; Microsoft Source Asia, December 2025).
Why is Microsoft's Hyderabad data center different from Google's?
The critical differentiator is cooling technology. Microsoft's India South Central region uses air-cooled chillers that consume zero water for cooling — part of its next-generation datacenter design philosophy. This is a deliberate response to the growing pushback against water-intensive data centers in India.
Google's Visakhapatnam project, by contrast, has drawn legal challenges precisely because of its water footprint in a city that already has less water than it needs. The project also uses advanced air cooling, but the question is whether that promise is enough for communities watching their reservoirs drop.
The table below compares the two projects:
| Dimension | Microsoft (Hyderabad) | Google (Visakhapatnam) |
|---|---|---|
| Launch date | August 6, 2026 (live) | Foundation stone April 28, 2026; projected multi-year buildout |
| Total investment | $20.5 billion (India-wide) | $15 billion (project-specific) |
| Cooling technology | Air-cooled chillers (zero water for cooling) | Advanced air cooling (claimed); details unconfirmed in environmental clearance |
| Environmental opposition | Minimal — zero-water design pre-empts water conflicts | Multiple court cases; PIL in Andhra Pradesh High Court; 3 cases at environmental court |
| Partnership | Direct Microsoft region | Google + Adani Group (AdaniConneX) |
| Jobs projected | Not disclosed for this region | Up to 188,000 regional jobs |
| Key early customer | HDFC Bank, Adani Group, Bajaj Finance | State government of Andhra Pradesh |

How much water do data centers actually consume?
Each megawatt of data center capacity requires approximately 25 million litres of water per year under typical evaporative cooling, according to Karnataka's IT Minister Priyank Kharge, who told the state assembly in March 2026 that data centres were "heavy water and energy guzzlers" (The Hindu, March 2026). He added: "If you ask five questions on ChatGPT, 500 ml of water is needed."
Applied to India's current 1.5 gigawatt operational data centre capacity, that implies roughly 37.5 billion litres annually from data centres alone. India's capacity is projected to grow to 8–10 gigawatts by 2030 — a six-fold expansion that would multiply the water demand proportionally (Down to Earth, 2026).
For context, Google consumed approximately 31 billion litres of water across all its data centres globally in 2024, according to its own 2025 Environmental Report (Google 2025 Environmental Report). A single hyperscale facility in a water-stressed Indian city draws from a very different resource base than a facility in a temperate climate with abundant water.
Why is Visakhapatnam's water a problem for a data center?
Visakhapatnam, a coastal city of 2.5 million people, already cannot meet its water demand. The state government confirms the city receives about 410 million litres of water per day from its reservoirs and rivers, against a requirement of 480 million litres per day — a daily shortfall of 70 million litres (Reuters, August 6, 2026; The Hindu, 2026).
The GVMC (Visakhapatnam Municipal Corporation) projects the city's water requirement will rise to 726 MLD by 2040 (The Hindu, GVMC projection). Adding a hyperscale data centre — even one using air cooling — to a city that already rations water is what triggered the backlash.
Activist groups including Green Visakha and Jal Biradari have filed public interest litigation in the Andhra Pradesh High Court, arguing that the project could strain local water supplies. The court has asked the state government to respond, with the next hearing scheduled for August 24, 2026 (edie, 2026).
Protesters have marched holding banners reading "We cannot drink DATA" and painting handcuffs on the Google logo, according to social media posts reviewed by Reuters.
What is the Kambalakonda Wildlife Sanctuary conflict?
The Kambalakonda Wildlife Sanctuary, located just 860 metres from the Google data center site, is a protected habitat for leopards and pangolins (Reuters, August 6, 2026). The public interest litigation in the Andhra Pradesh High Court raises concerns that heavy construction and noise will disrupt the sanctuary.
The state government has argued the site is farther away than legally required. Google has pledged to implement noise-dampening measures to remain "a quiet, unobtrusive neighbour" (Reuters, August 6, 2026).
Separately, the Human Rights Forum has filed three additional cases at India's environmental court (the National Green Tribunal), seeking a halt to construction. These cases argue the state cleared the project without properly assessing the impact of drawing water from a rural drinking-water scheme (Reuters, August 6, 2026).
What cooling technologies exist, and which ones avoid water?
The cooling technology choice is the single biggest determinant of a data center's water footprint. Here is what the options look like:
| Cooling Type | Water Use | Energy Use | Best Climate | Trade-off |
|---|---|---|---|---|
| Evaporative (cooling towers) | High — ~25M L/MW/year in India | Moderate | Dry/hot — water loss is highest | Lowest energy cost, highest water cost |
| Air-cooled chillers | Zero for cooling | Higher (fans + compressors) | Moderate climates | More energy-intensive but no water consumption |
| Liquid cooling (direct-to-chip) | Low — closed-loop, minimal loss | Low — far more efficient at heat removal | Any — especially AI/GPU dense | Higher capital cost; best for AI workloads |
| Seawater cooling (proposed for Vizag) | Zero freshwater (uses seawater) | Moderate | Coastal sites only | Corrosion, marine ecosystem impacts unclear |
Microsoft chose air-cooled chillers for Hyderabad specifically because zero-water cooling pre-empts the resource conflict that Google is now fighting in court. The trade-off is higher energy consumption — but in India's context, where water stress is an existential community issue and power can increasingly come from renewables, it is the safer regulatory and social choice.
Is this happening only in India?
No. The tension between AI data centers and local resources is a global pattern. In 2025 alone, local opposition in the United States delayed or blocked data center projects worth up to $152 billion, according to estimates from Data Centre Watch (CB Insights / StartupNews, 2026). Communities in Virginia, Dublin, Santiago, Maine, and Vancouver have organized against hyperscale facilities over water, power, and land-use concerns.
India's situation is distinctive because it sits at the intersection of extreme water stress, rapid AI infrastructure expansion, and a regulatory framework that has not yet classified data centers as a separate category for environmental clearance (Mongabay India, May 2026). A WRI India report found that more than half of India's data centres are located in water-stressed regions. The Central Ground Water Board has found that Bengaluru extracts almost 10 times the water it recharges each year — and data centres in the city's eastern and southeastern corridors draw from the same aquifers as residents facing rationing (Down to Earth, 2026).
What does zero-water cooling mean for businesses using Azure in India?
For enterprises evaluating cloud infrastructure in India, the Microsoft Hyderabad region's zero-water cooling has three practical implications:
Lower regulatory and ESG risk. Your cloud workloads are not drawing on local water supplies in a city that rations water. This matters for ESG reporting and for companies with sustainability commitments. If your organization tracks Scope 3 environmental impacts, the infrastructure choice affects your footprint.
Data residency without the controversy. India's DPDP Act and sectoral regulators increasingly require data localization. Having a fourth region — with a clean environmental profile — gives regulated industries (banking, insurance, healthcare) a compliant option without attaching their brand to environmental disputes.
AI workload readiness. Three availability zones with AI-optimized compute means HDFC Bank, Adani Group, and Bajaj Finance are already positioning for GPU-intensive workloads. The region supports Azure's full AI stack. If you are building AI workloads for Indian users, the latency and compliance advantages are real.
By contrast, organizations relying on infrastructure in regions facing environmental litigation carry a different risk: if a project is delayed or halted by court order, capacity expansion plans may not materialize on the expected timeline. This is not hypothetical — the Andhra Pradesh High Court is actively reviewing the Visakhapatnam project.
How big is India's data center market?
India's public cloud services spending will reach $45.7 billion by 2030, growing at 22.2% annually, with AI spending expanding at double that rate, according to IDC's Dr. William Lee, cited in Microsoft's launch announcement (Microsoft Source Asia, August 2026).
India's data centre capacity reached 1.5 gigawatts by end of 2025, with Deloitte projecting 8 to 10 gigawatts by 2030 (Down to Earth, 2026). The Union Budget 2026 extended a tax holiday until 2047 for foreign companies building data centres in India, which has been a major incentive attracting hyperscale investment, as we've covered in our analysis of India's 2026 tax amendment bill for cloud investment.
What this means for you
If your organization is building AI workloads for the Indian market, the lesson is clear: infrastructure siting now carries environmental risk that can determine whether a project succeeds or stalls. When evaluating cloud regions or colocation in India, ask three questions:
What cooling technology does the facility use? Air-cooled or liquid-cooled designs that avoid or minimize water consumption are increasingly the baseline expectation — not a premium feature.
Where is the water coming from? A facility in a water-stressed district — even with air cooling — may still draw on local aquifers for other operational needs. Check whether the operator has committed to using only treated water or has secured independent water rights.
Is the project facing legal challenges? Before committing workloads to a region under litigation, understand the timeline risk. Court-ordered halts can delay capacity for months or years.
The companies that get this right — like Microsoft with zero-water cooling in Hyderabad — will operate with community license. The ones that don't will spend more time in courtrooms than in server rooms.

FAQ
Q: What is Microsoft's India South Central region? A: It is Microsoft's fourth cloud region in India, launched August 6, 2026, in Hyderabad. It features three availability zones, air-cooled chillers that consume zero water for cooling, and is part of Microsoft's $20.5 billion investment commitment to India's cloud and AI infrastructure. Early customers include HDFC Bank, Adani Group, and Bajaj Finance.
Q: Why are people protesting Google's data center in Visakhapatnam? A: Activists and local residents are protesting because Visakhapatnam already has a water deficit (410 million litres/day supply vs 480 million litres/day demand for 2.5 million residents), and the data center site is just 860 metres from the Kambalakonda Wildlife Sanctuary, home to leopards and pangolins. Multiple court cases are pending.
Q: How much water does an AI data center use? A: Under typical evaporative cooling, each megawatt of data center capacity requires approximately 25 million litres of water per year (Karnataka IT Minister Priyank Kharge, March 2026). India's current 1.5 GW of data centre capacity implies roughly 37.5 billion litres annually. Air-cooled chillers, as used in Microsoft's Hyderabad region, consume zero water for cooling.
Q: What is the Andhra Pradesh High Court case about? A: A public interest litigation filed by activist groups including Jal Biradari argues that the Google data center project could strain local water supplies and threatens the nearby Kambalakonda Wildlife Sanctuary. The High Court has asked the state government to respond, with the next hearing scheduled for August 24, 2026. Three additional cases have been filed at India's environmental court by the Human Rights Forum.
Q: Does zero-water cooling mean the data center uses no water at all? A: Not necessarily. Zero-water cooling means the cooling system (air-cooled chillers) does not consume water for the evaporative cooling loop. The facility may still use small amounts of water for other purposes (humidification, maintenance, domestic use by staff). The key distinction is eliminating the large evaporative water loss that makes traditional data centers water-intensive in hot climates.
Q: Is India's data center boom sustainable? A: It depends on cooling technology, siting decisions, and regulatory enforcement. More than half of India's existing data centres are in water-stressed regions (WRI India). India has no national data centre policy with uniform water or energy benchmarks. Without mandatory water disclosure and a shift to zero-water or closed-loop cooling at scale, the projected six-fold capacity expansion by 2030 will significantly deepen the water conflict.
