Continuous pipeline monitoring
DALI uses fiber optics to detect leaks and intrusions, keeping your pipeline infrastructure secure.
Advanced monitoring for real-time leak and intrusion detection in pipelines
Detect leaks and intrusions in pipelines carrying drinking water or other liquids using Distributed Acoustic Sensing (DAS) and fiber optic technology. With advanced 24/7 monitoring, DALI helps utility companies and industrial facilities reduce Non-Revenue Water (NRW) losses, minimize waste, and prevent costly incidents. The system provides real-time alerts with 5-meter accuracy over long distances and is compatible with pipelines of any size or material, including plastic.
Unlock the power of DALI
Swift installation
DALI is installed seamlessly without interrupting pipeline operations and is designed for easy access to pipelines, including bypassing valves.
24/7 monitoring
Your pipeline operates 24/7, and so does DALI. Gain continuous monitoring for optimized asset management and peace of mind.
High accuracy
DALI provides pinpoint accuracy, automatically detecting leaks and intrusions within 5-meter precision.
Any pipeline, any material
DALI is compatible with all types of pipelines, from steel water mains to plastic industrial pipelines, ensuring comprehensive coverage.
Drinking water approved
All DALI components are strictly tested and approved for safe use in drinking water applications.
Improve asset management
DALI helps reduce the risk of major pipe failures while extending the lifespan of aging pipelines, allowing for efficient maintenance planning.

Build your own fiber optic network
DALI requires only one optical fiber for monitoring while enabling other fibers to connect and remotely control network assets such as valves and sensors. This setup supports robust data communication networks, transforming water pipelines into fiber backbones in partnership with telecom operators. With a capacity of up to 144 fibers, DALI ensures secure connections to network infrastructure and opens opportunities for leasing fiber capacity to telecom providers.
From monitoring to actionable insights
DALI leverages advanced fiber optic technology with Distributed Acoustic Sensing (DAS) to detect leaks and intrusions in real-time, enabling cost-effective decision-making.
1. Hassle-free installation
A project-specific fiber optic cable is installed within the pipeline, serving as a continuous array of thousands of acoustic sensors that span the entire lenght of the pipeline.

2. Smart pipeline monitoring
The Distributed Acoustic Sensor (DAS) is connected to one end of the fiber and utilizes a laser to send short pulses of light along the fiber. This process generates a unique pattern of reflections. Environmental vibrations create disturbances that alter this reflection pattern within the pipeline. The Distributed Acoustic Sensing (DAS) device analyzes these modified optical signals to detect potential leaks and intrusions.
3. Real-time monitoring and automatic alerts
DALI leverages advanced signal processing and machine learning software to accurately detect events such as leaks and intrusions. Users can monitor pipeline status in real time through an online dashboard, which displays alarms and sends notifications via email, SMS, or SCADA systems.
4. Make smart and informed decisions
The DALI monitoring system offers a long service life and typically costs less than 1% of a complete pipeline replacement. In return, you gain an extended pipeline lifespan, reduced Non-Revenue Water (NRW) losses, and peace of mind regarding your pipeline infrastructure.
Protect your pipeline infrastructure with fiber optic monitoring
Discover the potential of DALI in our downloadable brochure. With the next-gen pipeline monitoring solution and a data-driven approach you can continuously protect your pipeline infrastructure.
The DAS (Distributed Acoustic Sensor) that is at the heart of DALI detects any sounds or acoustic vibrations on the cable, from sub-Hz to several kHz (kilohertz). It registers any sound, including leaks, pumps, nearby digging activity, or unauthorized intrusions on the pipe. Advanced AI-based signal processing algorithms then filter out any irrelevant signals and raise an alarm in case of a leak or other important anomaly.
None. The entire DALI system can be installed on a live pipeline, without service interruptions. Thanks to our unique installation system, the fiber optic cable can be inserted, pulled, and extracted from the pipeline while the pipeline remains operational.
A single DAS can cover up to 70 km of pipeline. If you place the DAS in a central location and use an optical switch, you can even monitor several times that distance. This makes DALI ideally suited for monitoring long, critical trunk mains. The fiber optic cable is installed in shorter reel lengths (facilitating installation and maintenance) and then spliced together into one continuous fiber link.
Yes. The DALI cable contains 12 or even 144 fibers, of which only 1 is needed for the monitoring. The other fibers can be used to create an internal communication network, or even be leased to telecom companies that are developing a fiber backbone.
