Approximately 48.6 billion cubic meters of water are lost around the world every day. According to the International Water Association (IWA), the main culprits for this loss are underground leaks on water mains and service pipes. To monitor leaks in water pipeline networks, researchers at the Polytechnic University of Milan have experimented with a novel method using fibre optics — the inexpensive and commonly- used technology that allows us to have fast internet at home. The scientists developed a distributed fibre optic sensing (DFOS) cable based on the so-called Stimulated Brillouin Scattering (SBS) technology, which enables the processing and storage…
