Amid an ongoing drought and heatwave in the UK, with the Drinking Water Inspectorate (DWI) calling for a more proactive approach to drinking water risk, Kohtari has stressed the importance of combining trusted predictions with operational experience, transparent governance and human judgement.
With Ofwat also publishing its AI adoption plan as almost 40% of the UK faces water-use restrictions, Kohtari says decisions should not be handed over to an algorithm.
“The real value is in analysing multiple sources together, from historic water quality data to weather, satellite and catchment data,” said Kohtari managing director James Sumsion. “Predictive models can identify changing conditions and relationships that would go undetected manually. Instead of simply recording what has happened, AI and machine learning can crucially help teams understand what is likely to happen next.”
He added: “The divide will not be between water companies that use AI and those that do not. It will be between those that can turn data into earlier action and those still forced to respond after risk has escalated. A forecast only creates value when it gives someone enough time and confidence to make a better decision.”
At a time when 71% of England, according to the Environment Agency, is in drought, with more than 27 million people now under water-use restrictions, the growing challenge of water resilience has been brought sharply into focus. This highlights the need for a proactive approach to protecting water supplies both now and in the future.
The DWI and Ofwat have both pointed towards a more proactive, future-ready water sector, with the DWI’s Chief Inspector’s Report calling for earlier identification and management of risk, rather than waiting for water quality or supply issues to emerge. Meanwhile, Ofwat’s AI adoption plan sets out how responsible AI could be adopted at scale across the future regulatory system.
“One focuses on risk. The other on technology. Together, they raise a bigger question: Are water companies building the strategies, data foundations and practical solutions needed for tomorrow’s risks, or still relying on traditional tools and reactive approaches?” Sumsion added. “The data needed to predict water risks already exists. The problem is that this information often sits across separate systems, teams and formats. This means that important patterns remain hidden, while operational decisions continue to depend on snapshots of current conditions or retrospective reports.”
“AI and machine learning change how that data is used. That shift becomes most valuable when applied to complex, fast-changing risks,” Sumsion continued. “Algal blooms are a clear example. They are influenced by a combination of weather, water quality, catchment conditions and reservoir behaviour. Looking at any one of these factors in isolation provides only part of the picture. Our algal bloom prediction solution, BloomIQ, connects environmental, weather, satellite, historical and operational data to forecast risk. Embedded into existing workflows, it gives teams the evidence they need to make earlier, data-led decisions that protect water quality and strengthen resilience.”
“Water companies may be making major capital decisions without a complete understanding of what is driving the problem or which intervention will have the greatest impact. Earlier visibility changes the decision-making window, so the next step is to truly work together and put practical solutions in place. We are ready to help enable water companies to make that shift, so that we can better protect our waters,” he concluded.
