District heating
Locating leaks in the district heating network
We help district heating utilities reduce their water losses and increase operational reliability. We specialize in detecting leaks in underground pipelines for both private customers, water utilities and utilities.
Technology, education and practical experience – all in one place
Danish Water Innovation specializes in acoustic leak detection and intelligent monitoring solutions for the utility sector. We help district heating utilities with everything from strategy, monitoring and training to equipment delivery and practical leak detection.
Our goal is to help utilities reduce heat loss, optimize operations and build the necessary skills to work systematically with monitoring and leak detection themselves.
More than 50 years of experience – now also in district heating
Acoustic leak detection has been one of the most effective methods for locating hidden leaks in drinking water networks for more than 50 years. This experience forms the foundation for the solutions we offer district heating supplies today.
Through thousands of leak searches, we have built a deep understanding of sound propagation, noise impacts and effective search methods. We combine this experience with modern sensors, intelligent data loggers and analysis tools developed for district heating networks.
When you collaborate with DWI, you not only get access to market-leading technology – you also get access to the experience and methodology that makes the technology valuable in practice.
More than equipment
We deliver much more than instruments. We help build a complete solution where technology, working methods and employee skills work together.
Some utilities want to do most of the monitoring and leak detection themselves. Others want us to assist with monitoring, analysis or the practical leak detection. Most choose a solution somewhere in between. That's why we always adapt the collaboration to the individual utility's organization, resources and objectives.
Intelligent monitoring of the wiring network
Using intelligent acoustic data loggers, the district heating network can be automatically monitored around the clock. The loggers register changes in the noise picture and identify areas with suspected leaks, so that errors are detected early and resources can be prioritized effectively.
If you wish, DWI can also monitor your logger network and analyze the collected data. This allows your employees to focus on daily operations, while we continuously assess alarms and help prioritize further efforts.

Professional equipment for operation and maintenance
We supply a complete range of professional equipment for district heating supplies, including:
- Acoustic leak loggers and analysis platforms
- Electronic listening devices (geophones)
- Correlators
- Wire locators and spindle locators
- Thermal cameras
- Special equipment for wire identification
- Cloud-based data and analysis solutions
We of course also help with equipment selection, implementation and training.
Courses and training
Technology only creates value when employees know how to use it in practice.
Therefore, DWI offers both basic courses, specialized courses and practical training in, among other things:
- Acoustic leak detection
- Wire search
- Use of data loggers
- Correlation
- Practical troubleshooting
- Strategic monitoring of power grids
The courses can be held at your location or as part of the DWI Leak Academy.
Collaboration at multiple levels
No district heating supply is the same, which is why we offer flexible collaboration models.
For some customers we primarily deliver instruments and training. For others we monitor the logger network, analyze data and assist with prioritizing alarms. For some utilities we perform the practical leak detection as an integrated part of the operation, while others use us as a technical sparring partner in connection with strategy, technology and competence development.
The collaboration is always based on the individual supply organization, needs and ambitions.
Cases and collaborations
The best documentation for our work is found with our customers.
On the water side, our collaborations with Glostrup Forsyning and HOFOR show, among other things, how different utilities can choose different collaboration models – from the provision of technology and training to ongoing monitoring, analysis and practical leak detection.
We now also offer the same flexibility to district heating supplies.
