Course Overview
Underground infrastructure networks—such as water, wastewater, and gas pipelines—are essential to the functionality and sustainability of modern cities and industrial facilities.
Over time, these networks deteriorate due to corrosion, aging, and environmental stress, requiring rehabilitation to maintain service continuity and environmental safety.
Traditional excavation methods for rehabilitation are often costly, disruptive, and environmentally invasive, leading to traffic congestion, surface damage, and extended downtime.
Trenchless technologies offer innovative, efficient, and non-invasive solutions to rehabilitate underground networks without the need for open-cut excavation.
These techniques include cured-in-place pipe (CIPP) lining, slip lining, pipe bursting, horizontal directional drilling (HDD), and robotic inspection systems.
This workshop is designed to equip participants with the theoretical knowledge and practical skills to assess network conditions, select appropriate trenchless methods, and design and implement rehabilitation projects effectively.
Through hands-on training, case studies, and technical evaluations, participants will learn how to apply trenchless solutions that reduce costs, minimize environmental impact, and enhance infrastructure resilience.
