Technology measures AC mains\u2019 residual stiffness with high accuracy<\/span><\/i><\/p>\n Brabant Water wanted to better understand the condition of their aging asbestos cement (AC) transmission mains. To achieve this, Isle initially performed a Technology Horizon Scan to identify technologies that could be scaled across their network. One of the technologies highlighted was KenWave’s DRI. DRI is a non-invasive, external inspection technology which measures residual pipe wall stiffness and interprets this data to determine structural thickness. Because of its non-invasive nature, it allows water mains to remain fully operational during assessment. It detects leaks and captures localized changes in effective structural wall thickness \u2014 particularly valuable for AC mains prone to leaching. These insights support asset management objectives, such as predicting remaining service life, assigning condition scores and prioritizing pipelines for replacement.<\/span><\/p>\n KenWave and Brabant Water conducted a trial through the Trial Reservoirs Initiative to demonstrate the value of KenWave’s pipeline condition assessment technology. The trial took place over a 2-kilometer section of a 400mm and 300mm Asbestos Cement water main. This section had already been inspected using an inline Ultrasonic Testing (UT) tool, providing the client with high-resolution baseline data. The purpose was to compare DRI results with UT data and other operational and deliverable KPIs to evaluate KenWave’s performance.\u00a0<\/span><\/p>\n The results established that the DRI technology offered a non-invasive approach to wall thickness accuracy which was just as effective as more traditional technologies including ultrasonic testing (UT) technologies, but without the associated risk or disruption.<\/span><\/p>\nVentajas del enfoque\/la innovaci\u00f3n<\/strong><\/h5>\n
