Acoustic-Based Pipe Assessment Technology Reduces Water Leakage Rates (Environmental Science & Technology)

Approximately 18% of Maple Ridge, British Columbia’s water system is comprised of asbestos cement and cast iron, and most of the leaks and breaks are experienced in these areas. Normally, Maple Ridge would analyze the break histories of parts of its water system to determine which sections needed to be prioritized for replacement. However, it began searching for a solution that would help support this approach by non-invasively measuring the effective wall thickness of selected water pipes as a means of better anticipating what sections were most vulnerable to future breaks.
