Water & Wastewater Asia – Interview mit Mark Nicol

Echologics was commissioned by GHD to measure approx. 5 km of distribution networks for the Washington Suburban Sanitary Commission (WSSC). This pilot project was initiated to meet three main objectives: 1) calibrating the developed Asset Management (AM) desktop model, 2) determining the importance of the pipes to be replaced based on the predictions of the asset management model, and 3) evaluating the Acoustic condition assessment technology developed by Echologics. A comprehensive test protocol was created for this pilot project. The AM desktop model was initially used to identify the worst condition pipelines and to plan replacement measures. The next step was the use of Echologics' patented acoustic pipe integrity testing (PIT) to examine selected segments that should be replaced. This was followed by ultrasound testing, on-site inspections, soil samples from the area and forensic analysis of randomly selected pipe sections. Echologics' proprietary acoustic PIT predicted that almost 70% of the pipes that were replaced based on predictions from the asset management model should not have been replaced, including nearly 40% that were still in or near original condition. The results of other tests confirmed these predictions. proprietary acoustic PIT predicted that nearly 70% of the pipes that were replaced based on asset management model predictions should not have been replaced, including nearly 40% that were still in or close to original condition. The results of other tests confirmed these predictions. proprietary acoustic PIT predicted that nearly 70% of the pipes that were replaced based on asset management model predictions should not have been replaced, including nearly 40% that were still in or close to original condition.
