England Is Running Out of Water. Could This Be the Next Big Technology Opportunity?

Turn on a tap in England and water appears almost instantly. That reliability makes it remarkably easy to assume that water is abundant, It is not.

The Environment Agency has warned that, without further action, England could face a public water supply deficit approaching five billion litres every day by 2055. That is roughly one-third of the amount currently supplied to the public each day.

The problem becomes even larger when the rest of the economy is considered. Agriculture, industry, energy production, data centres and other activities increasingly compete for the same finite resource. The Environment Agency now estimates that non-public water users could require an additional 1.2 billion litres per day by the 2050s.

England therefore has an infrastructure challenge hiding in plain sight.

We have spent years discussing the country’s future requirements for electricity, broadband, transport and computing capacity. Water may increasingly belong on the same list.

For technology founders, that creates an unusual opportunity.

The Water Crisis You Cannot See Yet

Water scarcity is psychologically difficult to understand when water continues to come out of the tap.

That is partly what makes the challenge dangerous.

Unlike an electricity blackout, water scarcity can develop gradually. Population grows. Housing expands. Industries require more water. Climate patterns change. Environmental rules correctly require more water to remain in rivers and ecosystems. Leakage continues. Eventually, the amount society wants to consume begins exceeding what can sustainably be supplied.

Parts of England are already experiencing those tensions.

The Environment Agency has previously identified areas including Cambridgeshire, Sussex, Suffolk and Norfolk where water availability has affected housing and economic development.

The issue is therefore no longer simply environmental.

Water is becoming an economic infrastructure constraint.

We Need to Think About Water Like We Think About Energy

Britain has become increasingly sophisticated about understanding electricity.

Smart meters measure consumption. National systems forecast demand. Energy can be traded. Businesses monitor usage. Renewable generation is connected to networks. Software increasingly helps balance supply and demand.

Water remains considerably less visible.

Many organisations know exactly how much electricity their buildings consumed yesterday but have a much weaker understanding of where, when and why they are consuming water.

That information gap becomes increasingly important as scarcity grows.

The Environment Agency’s latest national framework explicitly calls for England to move towards near-real-time management of water resources. Achieving that will require significantly better monitoring of abstraction, consumption, discharges and environmental conditions.

That sounds like environmental policy.

It is also a technology specification.

Agriculture Could Become a Smart-Water Industry

Agriculture provides one of the clearest opportunities.

Outside public water supply, agriculture represents around 30 per cent of England’s recent consumptive freshwater abstraction.

Farmers need water, but they do not necessarily need to apply the same amount of water everywhere at the same time.

Soil sensors, weather information, satellite imagery and crop data can increasingly help determine where irrigation is actually required.

The Environment Agency is now explicitly advocating this kind of smart farming. Its latest framework describes a future in which farmers could use near-real-time information about water availability, sensors to improve irrigation scheduling and better monitoring to identify leaks and inefficiencies.

Instead of simply asking farmers to use less water, technology could help them use water more precisely.

That creates opportunities for companies building sensors, irrigation intelligence, farm-management software and water forecasting systems.

Golf Courses Reveal How Strange the System Can Be

Consider another unlikely example: golf.

England has around 2,200 golf courses. The Environment Agency estimates that approximately 60 per cent use mains potable water for irrigation.

In other words, highly treated drinking water can be used to keep grass green.

Courses relying on direct abstraction consume around 10 million litres of water per day on average, with demand rising to approximately 24 million litres per day during summer.

The point is not that Britain should stop watering golf courses. It is that an increasingly water-stressed country needs to become much more intelligent about matching water quality to water use.

Grass does not necessarily require drinking-quality water.

That creates potential markets for rainwater capture, recycled water, storage systems, smart irrigation and alternative water networks.

The same principle applies across factories, construction sites, commercial buildings and other large water users.

The question becomes whether every activity currently supplied with potable water actually needs potable water.

Then There Are Data Centres

Artificial intelligence introduces another pressure.

Data centres require electricity, but many also require substantial amounts of water for cooling. Large facilities can consume millions of litres per day depending on their design, location, climate and cooling technology.

This creates an interesting infrastructure collision.

Britain wants to expand its AI and computing capacity. It also wants new housing, clean energy, greater food security and healthier rivers.

All of them can require water.

The Environment Agency now explicitly identifies data centres and artificial intelligence within national water-resource planning and says that future development requires improved understanding of their water requirements.

That means the location of tomorrow’s computing infrastructure cannot be considered purely through the availability of electricity and fibre.

Water may become part of the planning equation.

A data centre proposed in a water-stressed region could increasingly raise a straightforward question: where is its water going to come from?

The Founder Opportunity Is the Infrastructure Between the Infrastructure

This is where the technology opportunity becomes particularly interesting.

Britain obviously needs reservoirs, pipes, treatment facilities and other physical infrastructure. Those projects require billions of pounds, lengthy planning processes and major engineering programmes.

Start-ups are unlikely to build Britain’s next national reservoir.

But they can build the intelligence layer around the water system.

That could mean sensors that detect abnormal consumption before thousands of litres are lost. It could mean AI models that predict demand at street, farm or industrial-estate level. It could mean platforms that allow organisations to understand where alternative water supplies are available.

It could eventually mean digital infrastructure that helps organisations share water resources.

The picks-and-shovels opportunity may therefore be in making water measurable, predictable and transferable.

Seven Problems Worth Solving

The most interesting opportunity may eventually emerge from combining several of these ideas rather than treating them as separate products.

Imagine an industrial park where every major organisation understands its water consumption in real time. Software forecasts tomorrow’s demand using weather and production schedules. Alternative water sources are identified automatically. Businesses capable of using recycled water are matched with available supplies, while potable water is preserved for uses requiring drinking-water quality.

The technology required to create parts of this system already exists.

What is missing is coordination.

Could Water Become a Marketplace?

One of the more radical possibilities is that water resources could become more dynamically shared.

The Environment Agency is already exploring greater use of water-rights trading and sharing. Its latest national framework argues that existing abstraction rights could be distributed more efficiently and that water users should increasingly collaborate at catchment level.

This does not mean creating an unregulated commodity market where anybody can buy a river.

Water is an environmental resource, and abstraction has to remain carefully controlled.

But within those boundaries, digital platforms could potentially help organisations understand where water is available, who has rights to use it and whether those rights or resources could be shared more efficiently.

A farmer with storage capacity, an industrial user with reusable process water, a data centre requiring cooling and a local authority planning thousands of new homes are currently viewed as different sectors.

From a water-resource perspective, they are participants in the same system.

The Funding Landscape Is Changing

The timing is particularly interesting because regulators are actively looking for innovation.

Ofwat originally committed £400 million to its Innovation Fund for the 2025–2030 period, building on the first £200 million programme. The regulator now describes the wider programme as a £600 million Water Innovation Fund and says that more than £250 million has already been awarded to 143 projects.

Importantly, Ofwat does not want every idea to come from conventional water companies.

Its programmes have deliberately encouraged collaboration with start-ups, universities, technology companies, charities and organisations from outside the traditional water industry.

That matters because some of the solutions to Britain’s water problem may already exist somewhere else.

Agriculture has precision sensing. Energy has demand forecasting. Banking has marketplaces. Telecommunications has network monitoring. Manufacturing has digital twins. Technology companies have machine learning and IoT infrastructure.

The opportunity may be applying those capabilities to water.

We Should Be Careful With the Cape Town Comparison

Cape Town’s 2018 water crisis provides a powerful warning about what severe water scarcity can look like. The city came dangerously close to the widely discussed “Day Zero”, when municipal water supplies would have faced extraordinary restrictions.

England is not Cape Town.

Its climate, water infrastructure, regulatory environment and supply system are different, and suggesting that London is inevitably approaching its own Day Zero would be unnecessarily alarmist.

But Cape Town demonstrated something psychologically important about water.

Scarcity can remain abstract until suddenly it becomes personal.

The fact that the tap works today tells us remarkably little about whether the system is prepared for the demand of 2050.

The Bigger Picture

Water technology rarely receives the attention given to artificial intelligence, fintech, biotechnology or clean energy.

That may change.

England needs new reservoirs and infrastructure, but physical supply is only part of the solution. The country also needs to reduce leakage, improve efficiency, understand demand, coordinate different users and make better decisions about where water should come from and how it should be used.

That creates a technology challenge spanning IoT, artificial intelligence, satellite data, digital twins, marketplaces, robotics and infrastructure software.

The Environment Agency’s latest strategy effectively points in this direction. It calls for smarter farming, near-real-time water management, greater monitoring, collaboration between sectors and more flexible sharing of water resources.

For founders, the opportunity is therefore not necessarily to invent water.

It is to build the intelligence infrastructure that helps society understand and manage every litre it already has.

The next great infrastructure technology company may not begin with electricity, computing or transport. It could begin with something considerably less glamorous but even more fundamental.

When a resource becomes scarce, knowing where it is, who needs it, where it is being wasted and where it can be reused becomes enormously valuable. That is why England’s coming water challenge could also become one of its most important technology opportunities.
