A UK-based private utility that supplies drinking water to 15 million customers wanted to improve the safety of its water supply by transforming how it handled sections of its distribution network that had been cut off from the rest of the system. Although new water flows through these "dead leg" sections, they often contain trapped water that can stagnate and become breeding grounds for microbes that may contaminate the water supply and pose a health risk. Typically, identifying and addressing "dead legs" is a manual, labor-intensive process that requires the use of external water-quality teams. The utility wanted a faster, more automated process to reduce the threat and minimize costs.
