Hidden water leaks can cause significant damage, increase utility costs, and create long-term maintenance headaches, even in newly built developments. At Kew Bridge Apartments, smart water monitoring deployed by Quensus uncovered issues across 58 units during commissioning, preventing property damage and improving efficiency for residents and property managers alike.
According to Quensus, early intervention was crucial. Continuous monitoring revealed unusual water flow patterns that suggested underlying leaks were already emerging, despite the buildings being only a few years old. The client engaged Quensus to determine whether the irregular readings were isolated incidents or part of a wider problem.
Investigation through smart monitoring
Quensus installed smart sensors across individual apartment water systems to gain detailed insight into usage behaviour. A full survey covering all 58 apartments allowed consumption patterns to be analysed and compared.
The monitoring classified leaks according to severity. Minor drips were identified as Level 1, while continuous leaks requiring urgent attention were marked as Level 4. This digital analysis was then paired with targeted on-site inspections to confirm the root causes of abnormal water use.
The combination of technology and physical investigation ensured both accuracy in detection and practicality in resolution.
Key findings
The survey revealed a surprisingly high number of faults for a recently completed development. In one block alone, 29 leaks were discovered. Common causes included:
-
Limescale build-up affecting drop valves
-
Pneumatic flush hoses preventing valves from fully closing
-
Failed rubber washers inside water meter unions
These results highlighted how minor installation or material issues can escalate quickly into widespread inefficiencies, even in developments only two to three years post-construction.
Immediate outcomes and benefits
The project provided clear value for both residents and property managers. Early detection of leaks reduced the risk of property damage and lowered potential utility costs. Maintenance teams were given actionable, prioritised tasks based on verified data, while recurring fault types informed future planning.
Quensus’ approach demonstrated that proactive monitoring in new developments is essential. Hidden leaks often go unnoticed until they become costly or damaging, but early intervention ensures issues are managed before they escalate.
