Water and desalination for data centres
Water is a real consideration for data centres because cooling often depends on it. Dholera's smart-city Activation Area (the first phase of Dholera to get roads, water, power and drainage) includes a water treatment plant of about 50 MLD along with reservoirs and a recycled-water network, which is the confirmed water infrastructure serving the developed zone today. Longer-range supply options, including coastal desalination, are discussed because Dholera sits on the Gulf of Khambhat coast, but no desalination plant is confirmed and its capacity or status is not established. This page explains why water matters for data centres, what Dholera has today, and why desalination comes up as a planned option rather than existing infrastructure.

Why water matters for data centres
Data centres generate a great deal of heat, and that heat has to be removed continuously or the equipment fails. Cooling is therefore one of the defining challenges of running a large facility, and many cooling approaches rely on water, whether through evaporative systems or water-cooled loops. Artificial intelligence has sharpened the problem. AI workloads run at high power density, meaning each rack draws more power and produces more heat than traditional hosting, which raises the cooling load and, depending on the design, the water demand. This is a well-established feature of modern AI infrastructure across the industry. For any location hoping to host large data centres, a dependable water supply is part of the basic checklist alongside reliable power and good connectivity. It is worth noting that cooling technology varies. Some designs use large volumes of water, others use closed loops that consume far less, and air-based or advanced liquid cooling can cut water use further. So water demand is not fixed, it depends on the cooling approach an operator chooses and the local climate. The general point still holds. A region marketing itself to data centre operators needs a credible answer on water, both for the volumes a campus might use and for how that use is sourced and recycled so it does not strain the surrounding area.
What Dholera has today
The confirmed water infrastructure at Dholera sits in the smart-city Activation Area, the first developed zone of the wider region. It includes a water treatment plant of about 50 MLD, meaning roughly 50 million litres per day of treatment capacity, along with reservoirs for storage and a recycled-water network. That combination is meaningful for data centres because recycling matters as much as raw supply. A recycled-water network allows treated water to be reused rather than drawn fresh each time, which reduces the net demand a large consumer places on the region. Reservoirs add resilience by buffering supply against variability. The honest framing is that this infrastructure serves the currently developed Activation Area and reflects the planning of a greenfield region built deliberately under the Delhi Mumbai Industrial Corridor and the Gujarat Special Investment Region Act of 2009. What it does not do is settle the question of very large, sustained water demand from a full build-out of data centres at the scale the region aspires to. The roughly 50 MLD figure is treatment capacity for the developed zone, not a dedicated allocation for a hyperscale data centre campus. As data centre plans such as the L&T Vyoma project move from announcement toward construction, the specific water arrangements for cooling those facilities will be one of the practical details to watch.
Why desalination comes up
Desalination enters the conversation for a simple geographic reason. Dholera sits on the Gulf of Khambhat coast, so the sea is nearby, and coastal locations with large future water needs naturally consider turning seawater into usable fresh water. For a region planning for heavy industry and potentially large data centres over the long term, desalination is one of the options that gets discussed as a way to secure supply without leaning entirely on inland freshwater sources. That is the logic behind why it appears in discussions of Dholera's water future. The essential caveat has to be stated plainly. No desalination plant at Dholera is confirmed, and its capacity, cost, timeline and status are not established in a way that can be reported as fact. It should be treated as a planned or potential option under consideration, not as existing infrastructure and not as a committed project. Desalination is also capital-intensive and energy-intensive, which is one reason it tends to be a long-range consideration rather than an early build, and any serious plan would have to account for the power it consumes, ideally from the region's renewable supply. The responsible way to describe Dholera's water story, then, is to separate the confirmed Activation Area infrastructure from the coastal desalination idea, which remains an unverified possibility rather than a plant on the ground.
How to read Dholera's water picture
Putting the pieces together gives a balanced view. On the confirmed side, the Activation Area has a water treatment plant of about 50 MLD, reservoirs and a recycled-water network, which is real infrastructure serving the developed zone and reflects a region designed with water planning built in. On the unconfirmed side sits coastal desalination, discussed because of the Gulf of Khambhat location but not confirmed as a plant, a capacity or a committed project. For anyone assessing Dholera as a data centre destination, water sits alongside power as a factor to track rather than a solved problem. The useful questions are practical. What cooling approach will large campuses use, since that determines how much water they actually need. How much of their supply will come from recycled water through the existing network. And whether long-range options such as desalination move from discussion toward a defined project as demand grows. It would be misleading to claim Dholera has abundant confirmed water for hyperscale computing, and equally misleading to claim it has none. The accurate statement is that the developed zone has treated and recycled water infrastructure today, that larger future demand is anticipated in the region's planning, and that the headline coastal solution often mentioned, desalination, remains a planned option whose details are not yet established.
