TRENCHLESS | NO-DIG NORTH 2025 PREVIEW


Horizontal Direct Drilling (HDD):


This is also a full-day course and its focus on HDD considers six keys areas: (1) operation and application; (2) equipment and materials; (3) planning, including surface and geological investigations, utility surveys, bore planning, and regulations and permitting; (4) job site safety; (5) risk reduction, troubleshooting and mitigation; and, (6) design. Cured in Place Pipe (CIPP): This is the third of the full-day courses. Its aim is to provide an in-depth overview of water, wastewater mainline and sewer lateral pipe rehabilitation using CIPP from planning to design to job completion.


TECHNICAL PROGRAMME The main Technical Programme of the conference runs over two full and packed days. The programme will be structured in half-day blocks,


throughout which there will be five parallel tracks (T1-5), running simultaneously. Typically, each track in a half-day session will have


four presentations. The No-Dig North and ISTT No-Dig Technical

Track 2 (T2) 1 Sustainable pipeline rehab: evaluating the carbon footprint/Inventory of CIPP technology in Taipei’s water infrastructure maintenance


2 Developing GIS-based risk matrix to assess seismic vulnerability of water pipelines based on material type and soil conditions in Taiwan


3 Estimating depth of neutralisation in concrete using near-infrared spectroscopy with hyperspectral camera


4 Pressure sewers: comparative performance assessment of rehabilitation technologies and inspection techniques in Germany


Track 3 (T3) 1 Lessons learned from the CIPP lining of a 72-inch sewer interceptor amidst wetlands and landfills


2 The variability of flexural properties with CIPP field samples
