Evaluation of an Un-Tethered Free-Swimming Acoustic Leak Detection Technology
In September of 2007, the San Diego County Water Authority (SDCWA) initiated a project to evaluate leak detection technologies applicable for large diameter water transmission mains. One of the selected technologies was an un-tethered, free-swimming acoustic leak detection device that could be released into the pipeline's flow. The purpose of the project was to evaluate the technology's ability to identify and locate potential leaks in a large diameter water transmission main over an extended distance. The free-swimming acoustic leak detection device demonstrated an ability to successfully identify and locate leaks in large diameter water transmission pipelines. The device was inserted into a fully operational pipeline and was released into the flow stream to monitor many miles of pipeline during a single deployment. A 4" diameter access was required for both insertion and retrieval of the device. Because the device traveled in the water column and passed directly adjacent to the leak, it clearly and distinctly identified the noise signature created by each leak. The position of the device was tracked and recorded by an acoustic receiver on the surface. This recorded data allowed for correlation of any identified leak with the position of the device in the pipeline. This paper will address the actual field performance of the free swimming acoustic leak detection device as utilized for the SDCWA project.
