Lightsonic Ltd

Lightsonic was created to address a persistent weakness in water infrastructure: utility networks can extend for thousands of kilometres, yet much of their pipework remains difficult to monitor continuously. Leaks can therefore remain undetected for months, contributing to water loss, inefficient field operations and avoidable investigation costs. The company identified an overlooked asset that could help close this gap: telecommunications fibre already installed alongside many pipelines. Rather than requiring utilities to deploy thousands of new sensors, Lightsonic transforms existing fibre into a continuous sensing layer.

The company combines distributed fibre sensing, signal processing and machine learning to identify vibrations associated with leaks and separate them from traffic, construction and environmental noise. Its Lightsonic Sense technology processes the acoustic data, while Lightsonic Insights turns detections into prioritised points of interest for utility field teams. The approach supports earlier detection of low-flow leaks, operates across plastic, metal and mixed pipe networks, and is intended to expand from water-leak monitoring toward broader utility infrastructure intelligence. Lightsonic has worked with UK water utilities and telecom network partners on live deployments, while its UK and Norwegian operations position it to expand across Europe and other infrastructure markets.
