Crack and Leakage Detection on Underground Pipelines Using Acoustic Technique
Journal Title: Open Access Journal of Environmental and Soil Sciences - Year 2018, Vol 1, Issue 2
Abstract
In this study, a method of water leakage detection system was investigated using acoustic emission device, AQUA M 300D. It is used to pinpoint leakage sources for underground pipelines system. The leakage is detected by analyzing the feedback frequency, where leakage area produces higher frequency due to the vibration resulting from a high-pressure liquid that flows through the crevice. The method is successful to detect underground pipelines system leakage with 90% accuracy. Every year, the government spends high budget on improving water pipeline system by doing maintenance, replacing older water pipeline, and locating leakage area. There are large percentage of water loss due transportation from sources or treatment plants to users. Water loss can be attributed by several causes including leakage, metering error and misuse of public usage [1]. But, water loss due to leakage contributes a larger percentage [2]. There are several methods that can be used to detect water leakage. However, in this study, acoustic emission technique has been chosen as it is the best non-destructive test for underground water pipelines [3,4]. The tests of efficiency and compatibility of the technique in detecting underground water pipelines is explored. This paper will also discuss the failure analysis that commonly occurs, and the factors lead to it. The test is conducted at Universiti Pertahanan Nasional Malaysia.
