ISTT & IWA Joint Webinar
Strategic Trenchless Rehabilitation Technologies for Water Loss Reduction
Gary Wyeth (Chair, IWA Water Loss Specialist Group) • Ari Gashi (Rädlinger PRIMUS LINE GMBH) • Ivo Raphael Hemsing (SAERTEX) • Prof Mark Knight (SIPP Americas)
Overview
Water utilities worldwide face growing challenges from ageing pipe networks, increasing water scarcity, and financial pressures. More than 30% of treated drinking water is lost before reaching consumers, wasting valuable resources and revenue. Conventional pipe replacement in dense urban areas is often costly, disruptive, and difficult to implement.
Trenchless rehabilitation technologies offer a reliable and efficient alternative. They enable pipeline renewal with minimal surface disruption while restoring structural integrity and significantly reducing water loss.
This webinar, organised by the International Society for Trenchless Technology (ISTT) and the IWA Water Loss Specialist Group, brings together leading industry practitioners to present proven solutions applied in real-world conditions. Through practical case studies and lessons learned, participants will gain insights into how utilities can advance resilient, sustainable, and cost-effective infrastructure renewal while reducing water losses and improving network performance.
Target Audience
- Water utility managers and staff
- Strategic Asset managers
- Engineers
- Infrastructure planners
