Challenges of live sewer rehabilitation

About this event

Explore practical trenchless rehabilitation approaches for live sewer environments. Rehabilitating live sewer infrastructure presents a unique combination of engineering, operational and safety challenges. This presentation explores how trenchless rehabilitation methods can be applied in active sewer environments while maintaining service continuity, managing project risks and protecting worker safety. Drawing on practical project experience, the session will examine drainage inspection, cleaning and rehabilitation techniques, including cured-in-place pipe (CIPP) technology. Attendees will gain insights into flow management, bypass planning, restricted construction windows, installation requirements, curing processes and contingency measures that support safe and efficient project delivery. Please take note: If ytyphoon signal no. 8 or above, or the black rainstorm warning, is hoisted or announced to be hoisted within two hours prior to the start of the visit, the visit will be cancelled without further notice.
