Artificial intelligence is transforming almost every sector of the UK economy. From healthcare and manufacturing to finance and public services, AI promises to unlock productivity, accelerate innovation and support economic growth. Yet behind every AI model, chatbot and data-driven application, lies a growing dependency on water.
This summer, as temperatures climb and once again England and much of Europe face drought and mounting pressure on water supplies, the rapid growth of AI presents a new challenge. Data centres consume vast amounts of electricity, but they also rely on significant volumes of water to keep servers cool and operating efficiently. As AI workloads continue to grow, so too does demand for water at a time when climate change is compounding the pressure.
Traditionally, solutions to address water shortages include billion-pound infrastructure projects, more efficient cooling technologies or new reservoirs. All have an important role to play, but they take years to deliver and the need is pressing.
One of the fastest ways to relieve pressure on both water networks and the infrastructure supporting the digital economy is all too often overlooked. Every litre of water we choose not to waste reduces the energy required to treat, pump and heat it, easing demand across interconnected systems. In the age of AI, simple behavioural changes are no longer just about saving water; they are about building resilience across the entire water, energy and digital ecosystem.
And data-driven solutions will help foster sustainable management practices. By providing granular insights into water usage, flow, safety and wastage – these technologies empower decision-makers to make informed decisions.
Data-driven tools can be game changers
In the era of climate-conscious business, data-driven tools are emerging as game-changers, especially for tackling inefficiencies that would otherwise remain hidden. Take water leakage, a persistent issue that plagues both urban and rural networks. Advanced analytics can now detect leaks with remarkable precision, enabling quicker repairs and significantly reducing water loss – an achievement that no business or community can afford to overlook.
According to Water UK, leakage presents an ongoing headache for the UK water industry, with an estimated 19% of the water supply lost before it ever reaches consumers. More than three billion litres of treated drinking water are lost to leaks every day.
However, thanks to advances in technology, AI-powered detection tools are gathering pace to address the issue.
A team at Wolverhampton University, along with its partners, are working on ‘Space Eye’, which uses the latest satellite technology for faster, more accurate and cost-effective monitoring.
Another innovation is the deployment of AI systems, which uses sound to find leaks beneath the ground in London after Thames Water partnered with Fido and Microsoft to tackle the capital’s leaks. Although the project launched in 2023 – the target was set to reduce leaks by 20% by 2025. With 95% of leaks taking place underground, finding and fixing them is a major challenge.
Circularity supporting growth
The World Economic Forum has already warned that without a circular approach to water – reuse, efficiency and more system-wide planning – digital growth could be hindered by physical limits.
At a national level, under-investment, ageing assets and climate volatility are still treated as exceptions, rather than systemic threats. Concurrently, the UK’s future growth sectors are becoming more water-intensive. AI, cloud computing and data centres are now part of the critical economic infrastructure and require reliable water to operate.
In the bathroom, one of the biggest culprits of water waste stems from long showers, with over 2 billion litres going down our drains each year, something that is attracting attention from the UK’s innovators.
In one UK study, smart-technology using behavioural prompts in hotel showers has reduced water use by over half and energy and CO2 in rooms by 22%, illustrating how gentle nudges can reshape habits.
Reducing hot water use in hotels, homes and commercial buildings not only cuts carbon emissions, but also helps reduce energy demand and indirectly supports the resilience of the infrastructure that powers AI and the wider digital economy.
Nature’s infrastructure seeps through
The challenge facing the UK is not simply one of storing more water – it is about helping water stay in the landscape for longer. For decades, our infrastructure has been designed to move water away as quickly as possible through drains, rivers and engineered channels. That approach made sense when the priority was flood protection. But in a warming climate that much-needed water is no longer available during prolonged dry spells.
Nature works differently. Healthy landscapes operate through interconnected water loops, where rainfall follows multiple pathways rather than a single route to the sea. Some water replenishes groundwater, other reserves are stored in healthy soils, while some is taken up by vegetation and gradually returned to the atmosphere through evapotranspiration – helping to regulate local temperatures and even influence future rainfall. Instead of treating water as something to be removed, natural systems continuously circulate, store and reuse it.
This principle of multiple pathways enables living systems to be more resilient, because they contain alternative routes that allow essential resources to keep moving when one part of the system is under pressure. Applied to water, this means slowing its movement through landscapes, allowing it to seep into soils, recharging aquifers and sustaining ecosystems for longer. Rather than relying solely on rivers as faster transport routes, we can strengthen slower, interconnected water loops that carry moisture through groundwater, vegetation and the atmosphere over much longer timescales.
The implications extend well beyond agriculture or conservation. As AI adoption accelerates and data centres place greater demands on electricity and cooling, every part of the water cycle becomes more valuable. A landscape capable of retaining more water is better able to withstand drought, moderate temperatures, reduce wildfire risk and support more reliable water supplies for communities and critical infrastructure.
Slow seepage should be viewed as infrastructure – not simply environmental restoration. Measures such as restoring wetlands, improving soil health, planting trees, reconnecting floodplains and creating natural water storage all help keep water circulating within the landscape rather than losing it rapidly as runoff. They build a more regenerative water system – one that stores excess rainfall during wetter months and releases it gradually when it is needed most.
Mirroring a more resilient system
The same philosophy applies inside our towns, cities and buildings. Every litre of water saved through smarter technologies, behavioural change and more efficient use reduces the amount that must be abstracted, treated, heated and pumped. Together, these local actions complement nature’s own water loops, helping create a more resilient system that can adapt to increasing pressure from climate change, population growth and the expanding digital economy.
In the AI era, resilience will not come from bigger pipes or larger reservoirs alone. It will come from changing our thinking and approach to water scarcity to mimic nature – creating systems with more loops, more pathways and more opportunities for water to remain in circulation.
By changing our habits, learning to value water more and slowing down its path, we will provide nature and our communities with the capacity to regenerate, adapt and to thrive alongside AI.
