Left to log noise data over a period of time, the self-contained pods perform multiple correlations to identify sources of leak noise. Dedicated software then presents these leak positions overlaid on a schematic of the pipes in the area.
"The icons denoting pods and leaks are self-explanatory, making it easy when first using the product," said Water Loss Control Technician Brian E. Jensen.
Because the process can be carried out without supervision overnight, areas with daytime traffic or construction noise can still be surveyed successfully.
SCWC technicians claim that the system effectively cuts out a time-consuming stage of the leak finding process, noting that the product is not just a correlator, but also a sounding device. In contrast, other systems require the user to sound the network first and then correlate separately.
Southern California Water Company provides water services to 240,000 Californians. With the introduction of SoundSens, it became possible for a technician to survey an entire system containing 42 miles of water main in just a few days.
