CEO BLOG: From Smart Meters to Smart Systems: Why Data Must Become the Water Sector’s Decision Engine

The UK water sector is about to generate more data than ever before.

Over the next five years, millions of smart meters will be rolled out. Monitoring across networks, treatment works and catchments is becoming more sophisticated. Data will move closer to real time, more granular, and more widely available.

But more data is not the goal. Better decisions are.

The real opportunity is to turn this surge in data into a decision engine for the whole system—one that improves performance, strengthens resilience, and builds trust. If we don’t, we risk creating complexity without clarity.

From reacting to predicting

Historically, much of the sector has operated on hindsight. Leaks are fixed after they appear. Demand is managed through broad campaigns. Assets are maintained based on age or failure history.

Smart meters and enhanced monitoring change this.

With near real-time insight, companies can begin to detect continuous flow and hidden leaks earlier, identify abnormal consumption patterns at property level, predict asset failure based on behaviour, and understand demand at a much more granular level.

This enables a shift from reactive response to predictive intervention—a fundamental change in how the system is managed.

The bigger prize: systems thinking

The real value does not sit within individual datasets. It sits in how we connect them.

Today, data is often fragmented—customer data, network data, asset data and environmental data are held separately. But the system itself is interconnected.

A pressure change is not just an operational tweak. It affects leakage, bursts, customer experience, energy use and asset lifespan.

This is where systems thinking becomes essential.

Instead of asking “what does this dataset tell us?”, the sector needs to ask: “What does this mean for the system as a whole?”

The future is not just smart meters. It is smart systems.

Turning data into decisions

To unlock value, the sector needs a clear approach:
Sense: collect data from across the system
Understand: turn data into insight
Decide: balance competing priorities
Act: translate decisions into action
Learn: refine based on outcomes

The cyber challenge

The more connected and data-driven the sector becomes, the more exposed it is to cyber risk.

Smart meters, remote monitoring, cloud platforms and supply chain integrations all expand the attack surface.

At the same time, the UK is strengthening its regulatory framework through the forthcoming Cyber Security and Resilience Bill.

Cyber is no longer just an IT concern. It is a core resilience issue.

A new approach: secure-by-design systems

The sector needs to adopt secure-by-design systems thinking.

This means treating data platforms as critical infrastructure, managing boundaries between IT and operational systems, focusing on essential services, strengthening supply chain assurance, and designing for continued operation during disruption.

A moment of choice

Handled well, increased data can enable earlier leakage detection, more effective demand management, smarter investment decisions and greater resilience.

Handled poorly, it risks adding complexity and increasing vulnerability.

Final thought

The future of the water sector will not be defined by how much data it collects, but by whether it can turn that data into a secure, system-wide decision engine that delivers better outcomes.
