IoT-based monitoring of water pipes with leak noise loggers and sensors.
Modern water utilities are increasingly working with continuous monitoring of their pipeline networks. With the help of data loggers – also called leak noise loggers – leaks can be detected earlier, water losses reduced and operations planned more efficiently.
With DWI A / S We provide solutions for leak monitoring and analysis of water networks, where sensors, loggers and data work together with practical leak detection in the field.
From classic leak detection to permanent monitoring
Traditionally, many leaks are only discovered when they become visible or affect operations. With modern data loggers, water pipes can be monitored continuously.
Loggers record noise and vibrations in the pipes and send data for analysis. When patterns change, it may be a sign of an incipient leak.
This makes it possible to:
- detect hidden leaks earlier
- reduce water loss (NRW)
- prioritize leak detection
- understand how the wiring network develops over time
Leak Noise Loggers and IoT Monitoring of Water Supply Networks
The latest leak monitoring systems are based on IoT leak detection in water networks, where loggers communicate directly with analysis platforms.
A leak noise logger is an acoustic data logger that is mounted on installations in the wiring network and measures noise in the pipes over time.
Loggers are typically placed at:
- valves
- fire hydrants
- branch pipes
- strategic points in supply zones
From here, data is collected and analyzed to identify leaks and changes in the network.
Monitoring of supply zones (DMA)
In many water utilities, monitoring is organized into zones or District Metered Areas (DMA).
When loggers are systematically installed in an area, the supply can:
- monitor leaks in entire zones
- identify where water loss occurs
- plan targeted leak detection
- follow the effect of renovations
Zone-based monitoring is today a central method in the work of reducing water loss.

Reduction of water loss
Data loggers make it possible to work more systematically with monitoring water supplies.
Data loggers only work if the installations do
To obtain useful data from a wiring network, the installations must be accessible and correctly registered.
Loggers are typically mounted on valves in covers. If there is no access, space or correct registration in GIS, the data quality will be poor.
At DWI, we therefore work based on a simple experience:
In water supply, data only works if the installations do. The entire chain – from valve to cover to advanced data processing – must work.
That's why we always advise on installations, loggers and analysis.
Interaction between data loggers and leak detection
Data loggers do not replace classic leak detection – they make it more efficient.
Loggers can:
- identify areas with likely leaks
- reduce search areas
- support systematic network review
- provide better planning of fieldwork
The result is a more effective effort against water loss.
From data to analysis
When many loggers work together, a comprehensive picture of the wiring network emerges.
Data can be used for:
- automatic leak monitoring
- analysis of noise patterns
- prioritization of fieldwork
- documentation of water loss
This includes modern analysis tools and platforms that can provide a comprehensive overview of the network.

Delivery, setup and support
At DWI, we help with the entire process surrounding data loggers in water supplies.
It may include:
- choice of logger solution
- planning of zone surveillance
- installation and commissioning
- integration with analysis tools
- ongoing support
The goal is to establish a system that works in practice – not just on paper.
A central part of the work on water loss
Data loggers and leak noise loggers play an important role in modern strategies for:
- leak monitoring
- reduction of water loss
- smart water monitoring
- data-driven operation of water supplies
When data is combined with experience from the field, a much better basis for decision-making arises.
