EPCOR Cuts Water Waste via AI Leak Detection 4 Innovativeness 4/5 Advanced 4/5 - Advanced. An acoustic sensor + deep learning leak detection system uses GPT-4 on Azure OpenAI to precisely locate and prioritize leaks (including quiet leaks in plastic pipes) with field deployment and large non-revenue water reduction. EPCOR, Arizona's largest private water utility, faced the problem of high water loss—up to 40%—due to undetected leaks in its vast piped network, a challenge shared globally where some regions lose as much as 70% of their drinking water. To address this, EPCOR partnered with UK-based FIDO Tech and Microsoft. FIDO's AI acoustic tool, enhanced by GPT-4 and deployed on Azure OpenAI Service, analyzes acoustic sensor data from water pipes to precisely locate leaks, rank them by severity, and prioritize repairs.Since 2023, this technology has been deployed in several geographies, including Arizona, Mexico, South Africa, and the UK, in collaboration with organizations such as State Water Commission in Querétaro and Las Vegas Valley Water District. Microsoft's global water sustainability initiative leverages such AI-driven projects to support watershed replenishment and operational efficiency across utilities. The AI tool's ability to accurately detect even quiet leaks in plastic pipes, which have traditionally challenged old detection methods, leads to much faster repairs and reduced excavation costs for communities.FIDO sensors are attached to pipe infrastructure, capturing acoustic data that is then processed by deep learning models to differentiate genuine water leaks from background noise and other non-leak sources. The system can recommend optimal sensor placement, assess water volumes lost, and help schedule repairs for maximum impact. This advanced solution streamlines leak detection, lowers multi-million-dollar pumping and treatment costs, and supports water conservation efforts vital to arid regions.EPCOR's implementation resulted in a drop of non-revenue water from 27% to about 10%, translating into major cost savings and reduced supply strain. Due to the scalability and flexibility of FIDO's solution, sensors can be redeployed and moved, providing lasting benefits across rapidly expanding service areas.This project is a model for combining advanced AI, IoT, and deep learning to address pressing environmental and infrastructural challenges, demonstrating transferable benefits for utilities worldwide.
