The Data Centre Bet India Cannot Afford to Get Wrong

This October, three Indian states declared drought. Karnataka declared 217 of its 240 taluks. Maharashtra declared 265 of 358. Andhra Pradesh declared 388 of 688 mandals. Karnataka’s monsoon was its weakest since 1971, and El Niño is getting stronger. (El Niño is a natural warming of the sea surface in the central and eastern Pacific Ocean. It happens every few years. When the water there gets warmer than normal, it changes wind and rain patterns across the world.)

At the same time, India is signing some of the biggest AI data centre deals in its history. Amazon plans to invest about 21 billion dollars by 2030. Google is building a one-gigawatt hub near Visakhapatnam. Amazon is building a 422 megawatt facility in Thane.

Two stories are happening on one map. One is about a thirsty land. The other is about the thirstiest machines ever built.

Why AI needs so much water and power

AI chips run extremely hot. Data centres remove this heat by evaporating water, much like a cooling tower. Power plants also use water, so every unit of electricity carries hidden water use.

There is a trade-off. Cooling methods that use less water use more electricity. A data centre can be thirsty or power-hungry. It cannot easily be neither.

Industry estimates say Indian data centres used about 150 billion litres of water last year. That figure may double by 2030. AI data centres could add about 26 gigawatts of power demand by 2031–32.

The real problem is priority

One Navi Mumbai data centre is reported to use about 223,000 litres a day. That is small next to farm irrigation. So data centres are not the cause of this drought.

The problem is who gets water first. Data centres in the Mumbai region are promised water all day, every day. Only about 4 percent of that region has round-the-clock supply. In Thakurpada, a Navi Mumbai neighbourhood, homes get drinking water every other day. A data centre stands next door.

What the world is telling us

In the US and Europe, residents are opposing data centres because of noise, power bills and water stress. Microsoft paused a Michigan project in January 2026 to talk with the community.

When rich countries ask hard questions, companies look for easier places. I cannot prove this is why they come to India. But if our rules are weak or not enforced, India will carry the burden others refuse. Protests have already started in Thane and Visakhapatnam.

How long can India support this?

No honest expert can give a year count. It depends on three things: the monsoon, groundwater and the power grid.

About 600 million Indians already face high to extreme water stress, according to government data. Every weak monsoon makes the margin smaller. Andhra Pradesh says Vizag’s data centres will draw from the industrial share of the Polavaram project, without touching drinking water or irrigation. That is a promise. A deep drought will show whether it holds.

The risk of migration

Indian farm families already leave their villages when crops fail. If a drought district also loses water to industry, the push to leave grows stronger. This is not a prediction of a mass exodus. It is a warning about what happens when a weak monsoon meets weak planning.

What India’s leaders should do

1. Publish the contracts. Water and power terms of every data centre deal must be public.
2. Measure and report. Each site must report its water and power use every month, checked by an independent auditor.
3. Add a drought clause. In a declared drought, drinking water and irrigation come first. Data centres must cut use or switch to recycled water.
4. Ban fresh water for cooling. Allow only treated wastewater or closed-loop systems.
5. Make companies bring their own clean power. Households must not pay higher bills for AI.
6. Hold public hearings. No approval in a drought-declared district without an independent environmental review.
7. Enforce with penalties. A rule that is not enforced is only a suggestion.

But, water absorbs and carries away heat very well, and evaporating it is a cheap way to cool the hot chips, but it must be fresh water, because salty or dirty water would leave deposits and corrode the cooling equipment.

What citizens should do

Ask your local body how much water nearby data centres use. File Right to Information requests. Attend public hearings. Track tanker prices in your area. Silence helps only those who are not thirsty.

The closing thought

India can be part of the AI age. But it must not become the place where the world sends its thirst. A server can be moved to another city. A farmer cannot move his well.
