Underground water leaks represent one of the main challenges for Integrated Water Service operators. Detecting them is often difficult, costly, and invasive.
A recent project offers an advanced solution: a leak detection system based on Synthetic Aperture Radar (SAR) technology, capable of identifying underground moisture up to 40 meters deep, even in the most inaccessible areas, without the need for digging or invasive interventions.
SAR radar applied to water networks
The Synthetic Aperture Radar emits microwave pulses that penetrate the ground; the return echo, processed with advanced algorithms, generates a “tomogram” capable of identifying moisture variations.
Developed by the Technology Innovation Institute of Abu Dhabi, this innovation uses radar waves to scan the ground and detect anomalous zones, typically associated with water leaks.
Key advantages include:
- Deep, non-invasive detection – up to 40 meters deep without destructive interventions, even in hard-to-reach areas
- Fast diagnostics – leaks can be located in hours instead of weeks, significantly reducing on-site inspections
- Lower operational costs – fewer excavations and fewer service interruptions
- Reduced environmental and social impact – Targeted and limited interventions reduce noise, traffic, and water service disruptions
This is a concrete example of how technologies born in the aerospace sector can become valuable tools for network efficiency, leak reduction, and operational sustainability for utility managers.
Accadueo 2025: the future of the water sector starts here
Topics such as leak reduction and the adoption of digital strategies with a medium-to-long term outlook will be discussed during the conference program of the 18th edition of Accadueo, the international benchmark event for the entire water sector, scheduled from 7 to 9 October 2025 at BolognaFiere.
DISCOVER THE PRELIMINARY PROGRAM
An opportunity to stay up to date on emerging regulations, explore new water treatment technologies, and actively contribute to shaping the solutions that will guide the future of the sector.
