Nearly 30% of treated water does not reach customers. It leaks away in the network. For modern water systems, this means trillions of litres lost each year. Known as non-revenue water (NRW), it remains a persistent global challenge. It drains revenue, puts stress on assets, and complicates sustainability efforts.
Utilities have managed NRW in much the same way for decades. They often react only when there is a visible burst, a customer complaint, or during routine checks. By that time, the damage has already started. The delay between finding a problem and fixing it turns a small issue into a costly one.
But things are changing. Smart meters are changing how utilities monitor their networks. The data they provide helps catch anomalies early, reduce losses, and allow teams to act before issues escalate.
The high cost of leakage
Leakage is not a single-line loss. Its effects quietly spread throughout the system.
- Resource waste: Treated water comes with costs like energy, chemicals, labour and infrastructure. When it leaks, utilities lose more than just volume. They lose all the investment made in treating and moving that water. In energy-constrained systems, this waste raises the cost of every litre that reaches customers.
- Rising operational costs: Leaks disrupt pressure balance. Pumps have to work harder, using more energy. Equipment wears out quicker. Since leaks are often discovered late, repairs turn into urgent fixes instead of planned maintenance.
- Stress on infrastructure: Leaks alter hydraulic balance, causing pressure changes that stress aging pipes, joints, and valves. Small defects worsen, and hairline cracks can lead to full pipe failures.
- Public health risk: Pressure drops increase contamination risks. Openings that let water out can also let pollutants in. In dense or old networks, this risk is real, not just a theory.
- Sustainability impact: Leakage forces utilities to extract, treat, and pump more water than needed. In water-scarce regions, this is unsustainable.
The longer a leak remains undetected, the greater the consequences. So, tackling leakage is not just about recovering lost revenue, it is also about safeguarding infrastructure and communities. This protection requires continuous visibility and the ability to detect changes early, allowing for responses before failures happen. That is the promise of automated network integrity.
enabling automated network integrity
Preventing leakage at scale requires more than faster repairs. It requires a system that can sense, interpret, and act — continuously. Automated network integrity happens when smart meter data, analytics, and control systems work together.
Continuous detection: Smart meters capture high-resolution, time-stamped data. Over time, this builds a behavioral baseline for each connection. When aggregated, the data becomes a distributed sensing layer across the network. Anomalies stand out quickly — sustained low flow, abnormal night usage, sudden demand spikes. These patterns often signal unplanned water movement triggered by developing leaks. Changes in consumption patterns can show asset stress well before a noticeable failure. Instead of waiting for failure, the system detects deviation at its source.
Correlation and localisation: Detection is only the first step. The real value comes from correlation. When similar anomalies show up in nearby meters or in a district metered area (DMA), analytics can identify likely fault zones. Pressure and flow are connected. So, irregular demand changes might indicate pressure issues or pipe wear in a certain section. Utilities can then prioritise inspection and intervention based on calculated risk — not guesswork. Operations move from reactive troubleshooting to predictive asset management.
Automated containment: Detection without action is incomplete. Automated containment closes the loop. Advanced meters with remote shutoff can disconnect a connection when flow exceeds set limits. In the event of a severe leak or rupture at the service line, water loss is immediately limited. Property damage is reduced. Emergency dispatch pressure eases. The system does not alert. It acts.
Together, these capabilities redefine network integrity. It becomes a condition that is continuously monitored and actively managed, rather than just a response to an incident. Utilities adopt a closed-loop model: detect early, localise precisely, contain automatically, and intervene strategically.
A wrap up
Leaks will always be part of managing a water system. But how utilities respond to them is a choice. Reactive repair cycles make organisations chase visible failures. Automated network integrity changes this with continuous awareness. It transforms raw data into early signals. This helps utilities shift from fixing failures to managing risks.
More than the dramatic burst, it is the steady drip that causes more damage. And with the right visibility, that drip no longer has to go unnoticed.
How Infosys BPM can help
Every drop of water is a story waiting to be told. Infosys BPM’s solutions for utilities listen to the data flowing through smart meters and spot leaks before they turn into crises. By blending predictive analytics with automated network monitoring, we turn vast streams of readings into clear signals that enable timely interventions, preservation of water, and keeping the network healthy and reliable.
