Sensors Designed to Monitor Pipes After a Disaster

This article discusses a program developed by the University of California, Irvine, to outfit water systems with sensors that will alert officials in the event of a natural or human caused disaster to when and where pipes crack or break. The compact disc‐sized sensing devices attach to the surface of pressurized (drinking water) and nonpressurized (wastewater) pipes. The sensors detect changes in vibrations and sounds, which could indicate problems with pipes, and then relay the information wirelessly to a central location for recording, processing, and diagnostic analysis. The sensors will compliment existing supervisory and data acquisition systems (SCADA).
