Abstract

Evaluates the potential of a daily acoustic monitoring system to locate leaks promptly. Identifies differences in pipe, and the subsurface environment between the onset of detectable subsurface flow and the time when the leak actually surfaces. Also studies how leaks of varying types can be categorized by acoustic signature and pipe characteristics. Examines the structural characteristics of breaks captured near the time the leak starts, to gain additional insights into the dynamics of failure. Tailored Collaboration partner: American Water.
