Identifying issues early to prevent water loss, reduce cost and protect operations.
Leaks are one of the most common and costly causes of unnecessary water consumption. Many occur out of sight underground, behind walls or within plant and process systems and can continue undetected for months. Even minor leaks can significantly increase operational costs, create compliance issues, reduce asset efficiency and contribute to avoidable carbon emissions linked to water treatment and transport.
Left unresolved, leaks can escalate into service disruptions, water damage or operational downtime. In multi-site estates, the challenge is even greater, as small anomalies on individual meters are easily missed without proactive monitoring. Effective leak detection provides early warning, enabling organisations to address issues before costs escalate or operations are impacted. A structured approach is essential for financial control, risk reduction and long-term asset protection.

We combine advanced data analytics, smart metering and on-site investigations to rapidly identify, validate and locate potential leaks. Our monitoring systems highlight irregular consumption patterns, night flows and sudden spikes, giving you early visibility of issues across your estate. When a leak is suspected, our specialists carry out targeted assessments including acoustic detection, pressure testing and thermal imaging to confirm the source quickly and accurately.
Once identified, we support the full repair process, coordinating with your teams or supply-chain partners to restore normal operation with minimal disruption. Detailed reporting provides clarity on cost impacts, root cause and recommended preventive measures.
Aligned with Mitie’s Plan Zero ambitions, our service reduces wasted water, lowers operational carbon and improves estate resilience. The result is a proactive, insight-led approach that protects assets, reduces cost and strengthens long-term operational performance.
