Investigation on the Detection of Water Leaks in Small-Diameter Polyethylene Pipes Using Acoustic Emission Signals
Authors: , ,
Abstract: Active control of water losses is an essential strategy to increase the efficiency of urban water supply systems. This work deals with the early detection of leaks occurring in small-diameter service pipes of water distribution networks. Preliminary experiments were conducted in a test facility to assess the sensitivity of Acoustic Emission methods to leaking water flows. Acoustic Emission measurements were performed on an unburied polyethylene pipe with artificially generated leaks. A good correlation between several monitored parameters and the characteristics of the examined leaks could be identified.
