Daybreak - India's data centre boom is a bet on water it doesn't have

Episode Date: April 13, 2026

India is building data centres at unprecedented speed to support cloud services, AI, and digital growth. At the same time, cities across the country are struggling with water shortages and re...peated contamination of drinking-water supplies.A United Nations report describes this condition as water bankruptcy. It is the stage where water systems continue to function, but only by drawing down reserves that cannot recover fast enough.In this episode, host Snigdha Sharma looks at how India’s data centre push fits into that reality, drawing lessons from cities abroad where similar tensions have already surfaced.So as India builds for a digital future, the question is simple: who decides how much water that future can afford?**This episode was originally published on 22 Jan, 2026Daybreak is produced from the newsroom of The Ken, India’s first subscriber-only business news platform.

Starting point is 00:00:01 In one part of Madhya Pradesh's Indoor, this winter, people began waking up sick. It started with one house, then another and then another, and it didn't stop. The symptoms were familiar, vomiting, diarrhea, weakness. Local hospitals filled up quickly and doctors asked the usual questions. What did you eat? What did you drink? Eventually, officials realized that this was something bigger and began to tell. testing the water. Over the next few weeks, the number of deaths linked to contaminated drinking water in the city kept rising. As of yesterday, after another death was reported, the toll stood at
Starting point is 00:00:45 25. This is not happening in isolation. In Begum Ganj, another town in Madhya Pradesh, animal remains were found in rivers that supply drinking water. And all of this is not limited to smaller towns. In Bangalore, residents in at least two neighbourhoods complained this month that sewage was entering their taps. In Delhi, government records show tens of thousands of complaints related to water quality in less than a year. And let's not forget the water shortage across cities during summers, especially in Bangalore. Taken together, these episodes are a part of a wider pattern of chronic stress on the country's water systems. And a major global scientific report released by the United Nations just yesterday actually put language to this pressure.
Starting point is 00:01:38 Researchers at the United Nations University Institute for Water, Environment and Health say that many water systems around the world are now in a state of water bankruptcy, where long-term use and degradation have pushed rivers, aquifers and wetlands beyond the point where recovery to past conditions is realistic. This choice of word matters. It reflects a shift in how water is being understood because terms like water crisis and water stress no longer describe what is unfolding right in front of us. When you look at the report's global map, almost all of India and large parts of Asia
Starting point is 00:02:21 as well appear in deep red, indicating highest levels of risk. Yet, this is also the moment that India is investing heavily in infrastructure that simply assumes a steady, uninterrupted supply of freshwater. And data centers are a significant part of that push. They, as we all know, are essential to India's digital economy and tech sovereignty ambitions. and for the AI race in which we are already lagging far behind. But these two realities are rarely discussed together. You see one in public health reporting and the other in the business and tech pages of newspapers.
Starting point is 00:03:04 This episode begins where they intersect. What does it mean to build water-dependent infrastructure in cities where water itself is becoming harder to rely on? Welcome to Daybreak, a business podcast from the Canada. I'm your host, Nick Da Sharma, and I don't chase the new cycle. Instead, every day of the week, my colleague Rachel Vargis and I will come to you with one business story that is worth understanding and worth your time. To understand what is happening with drinking water across Indian cities, it helps to start upstream before the water even reaches a tap. Most large Indian cities no longer rely on one source of water because they just can't. Rivers are stretched, lakes are shrinking.
Starting point is 00:04:06 So cities do what they have been doing for years. They dig. Groundwater has become the quiet backbone of urban water supply. Bore wells supplement rivers, tankers pull from aquifers, and when surface water falls short, the ground below is expected to make up the difference. But groundwater works only when it has time to recharge. Rain has to see back into the soil and that needs open soil. More concrete means water does not get to seep down.
Starting point is 00:04:39 The thing is, ground water is a little bit like having savings. Water stored underground is meant to be drawn on when surface sources fall short. But savings only work if withdrawals slow down and deposits continue. This is what the UN report describes as water bankruptcy. The stage where withdrawals continue but deposits do not keep pace. That is exactly what is happening in India. In cities like Bangalore, groundwater is built into daily supply. When older bore wells run dry, new ones are drilled deeper.
Starting point is 00:05:16 Tankers travel further to find water and these steps keep steps running. But they also change how the system behaves. Water begins to arrive less evenly. Some days there is supply, some days there isn't. Pressure varies across neighborhoods and across hours. Municipal systems are forced into stop-start operations. And this matters because India's water infrastructure was never designed for this kind of flow. Most urban water networks assume steady pressure.
Starting point is 00:05:49 Pipes late decades ago were built for continuous supply. When water flows with interruptions, pressure inside the pipes drop. And when pressure drops, water from outside the pipes can seep through the cracks, joints and corrosion points. And this is where shortage and contamination meet. And the problem is that in India, testing and monitoring struggle to keep up with this reality. Different agencies test at different points and results take time. And when they do realize, exposure has often already happened. And that lag is why contamination stories are often discovered after people fall sick, not before. And the bankruptcy metaphor helps explain why this keeps happening. In financial bankruptcy,
Starting point is 00:06:38 spending continues even as income falls. The system looks functional on the outside, but the buffer is gone. One shock is enough to trigger a failure. Water bankruptcy works in a similar way. Cities continue to function by drawing down groundwater and stretching infrastructure, which means there is less room for and less ability to absorb stress. This is why recent water problems feel different. They appear in different forms and different cities, but they share the same underlying condition. Indian cities are operating water systems that still work,
Starting point is 00:07:16 but with shrinking margins and growing dependence on sources that cannot recover fast enough. And that is the reality that these systems now carry forward. And it is within this reality that India is making new infrastructure choices, choices that assume that water will be available, predictable, and uninterrupted. For more on this, stay tuned. Now that we've seen how India's water systems are stretched, let's look at a class of infrastructure that is being built as if water was reliably available every day uninterrupted. In India, right now, there is a huge surge of investment in data
Starting point is 00:08:04 centers. Big companies like Google and OpenAI are adding gigawatts of capacity to support cloud services, digital growth and AI. The overall data center market in India is projected to exceed $100 billion by just next year. These projects are mostly concentrated around cities like Mumbai, Hyderabad, Chennai and Bangal, the same urban centers that are already reporting water stress and intermittent supply. Data centers are buildings full of servers. They work around the clock and they generate a lot of heat. To manage that heat, most facilities use water in their cooling systems.
Starting point is 00:08:47 How much water varies by technology and climate, but research shows that numbers are large. And data centers in hot regions would obviously need more cooling capacity, which means more water. For context, a one megawatt data center can use roughly 20,000. million liters of water a year for cooling. Scale that up and a 30 megawatt facility could use hundreds of millions of liters annually. It is comparable to the yearly water use of tens of thousands of households. Naturally, this puts data centers in an unusual position. They are essential to digital services, but they are also permanent, continuous, high-volume water users.
Starting point is 00:09:31 And concerns about this pattern are already visited. in other parts of the world. In America's Oregon, residents sued to force the disclosure of how much water a Google Data Center was using during a prolonged drought. When the numbers became public, they showed that the facility was consuming around a quarter of the city's total water supply at peak times. And this was while residents were being forced to conserve water. In Arizona, again in the United States, residents and local officials have challenged permits for a
Starting point is 00:10:04 large data center campus in Maricopa County, arguing that approvals were granted without fully accounting for groundwater depletion. The state has since tightened rules around new water intensive developments in areas where aquifers are already overdrawn. In Ireland, in Europe, public opposition and legal challenges led local councils to pause or block new data center approvals in parts of Dublin after official assessments showed that election electricity and water demand from existing centers was already straining public infrastructure. The government later acknowledged that data centers had become a planning risk for essential services. In the Netherlands, courts ordered regional authorities to reassess permits for large data centers
Starting point is 00:10:53 after residents argued that freshwater use and heat discharge were affecting local water bodies during dry summers. Some projects were delayed or redesigned as a result. These cases show what happens when data centers arrive in places where water systems are already stretched. So, as of now, the only way we can do something about this is by asking authorities a simple question. How much water do we have? How much is being used? And who decided that was acceptable?
