Kew Bridge | Apartments

During the commissioning phase of a newly constructed apartment development at Kew Bridge, continuous water flow patterns were detected that suggested underlying leakage across multiple residential units. While the buildings were recently completed, the data indicated that hidden issues were already emerging that could lead to property damage, increased utility costs and long-term maintenance risks for residents.

The client engaged Quensus to investigate further and establish whether these patterns represented isolated faults or a wider systemic issue within the development.

‍

Investigation

Quensus deployed smart monitoring sensors across individual apartment systems to gain accurate visibility into water usage behaviour. A comprehensive survey was conducted across 58 apartments, allowing consumption patterns to be analysed in detail.

The monitoring identified a range of leak severities, from intermittent low-level drips classified as Level 1 through to continuous Level 4 leaks that required urgent attention.

Following data analysis, physical inspections were carried out within selected apartments to determine the precise causes behind the abnormal usage patterns. This combined digital monitoring and on-site investigation approach ensured both detection accuracy and practical resolution.

‍

Findings

The results highlighted a surprisingly high number of faults given the relatively new age of the buildings.

Within one block alone, 29 separate leaks were identified. The most common causes included:

• Limescale build-up leading to drop valve failure
• Pneumatic flush hoses preventing valves from fully closing
• Failed rubber washers inside water meter unions

‍

These issues were particularly notable given the development was only two to three years post-construction, demonstrating how quickly minor installation or material issues can escalate into widespread water inefficiencies.

‍

Outcomes

The investigation provided immediate value for both property managers and residents.

• Early identification of leaks reduced the risk of property damage
• Utility cost exposure was significantly reduced before issues escalated
• Maintenance teams gained clear, prioritised actions based on verified data
• Insight into recurring fault types informed future maintenance planning

‍

Most importantly, the project demonstrated the effectiveness of proactive monitoring within new developments, where hidden leaks often go unnoticed until costs or damage become substantial.

‍

Key Takeaway

Even newly built residential developments can experience systemic water issues within a short period of completion. Without detailed monitoring, minor faults can persist undetected and lead to higher costs, resident dissatisfaction and long-term infrastructure problems.

Smart water monitoring enables early intervention, protects assets and provides confidence that building services are operating as intended.
