Article: Santa Barbara Incorporates Acoustics to Prioritize Sewer Maintenance

Santa Barbara’s collection system relies on a cleaning cycle ranging from one month to 60 months. While they have been successful at reducing SSOs through increased cleaning efforts, they looked to further enhance efforts. Santa Barbara discovered that the majority of SSO events occurred from 6-in pipes on a 60-month cleaning cycle. Based on cost, speed and simplicity, they chose the SL-RAT to acoustically screen these lines to get a quick understanding of pipe conditions and deploy resources appropriately.

“We wanted to clean or inspect more. Prior CCTV work has helped us find structural defects and generate a rehabilitation backlog. The SL-RAT allows us to inspect much more pipe now and find blockage conditions before they create an SSO.”
