Aclara's STAR® ZoneScan leak-detection solution was jointly developed by Aclara and Zurich-based Gutermann International. The system employs data loggers placed on main valves that sample the sound waves generated by leaks. The data is automatically sent to the utility over the Aclara STAR® Network. There, the system's software correlates the data, pinpointing any leaks to within a few feet. The system can save municipal water utilities time by identifying possible leak locations remotely. It also encourages water conservation by helping utilities identify and fix leaks before they become emergencies.
