Drones and satellites for underground leaks

A pioneering study for detecting the location of underground water pipes and by extension for preventing leaks was published by EYATH S.A. in the internationally renowned journal “Remote Sensing”.

The innovation of the method is based on the combination of satellite data (Sentinel-2) with high-resolution images from drones (UAV) in the visible and near-infrared (NIR) spectrum. This combination, leveraging the advantages of each data source, ensures maximum accuracy in detection.

This methodology achieves: 1. Accurate mapping: locates the location of underground pipes with an accuracy of ±0.3 meters, allowing for the precise mapping of the network especially in areas with uncertainty. 2. Predictive maintenance: maps the evolution of the surface traces of the pipelines over time. This information is further investigated, so that it can be used in the future to detect leaks or mechanical damage before they become visible. In this way, a new model of preventive and predictive management of underground networks is explored, which allows for timely intervention long before visible damage occurs.

This is an initiative of the Research & Development Department of the Strategic Planning, Projects & Development Directorate of EYATH, which was implemented in close collaboration with other departments of the company, highlighting once again its ability to produce cutting-edge research.
