Introduction to Trenchless Technology

Introduction
Trenchless technologies include methods and tools for underground pipelines and utilities’ new installation, replacement, rehabilitation, locating, and condition assessment with minimum excavation from the surface. This course will present state-of-the-art trenchless methods and techniques to install, replace, and rehabilitate aging pipelines and utility ducts efficiently and cost-effectively. Topics include trenchless project feasibility analysis and planning; topographic and geotechnical considerations; selecting appropriate trenchless technology, pipe materials, and lining materials; risk analysis; and quality assurance and quality control. Furthermore, pipeline condition assessment techniques will be presented. Finally, the industry’s good practice guidelines, standards and specifications will be discussed. 

Why Trenchless Technologies?

Financial Benefits (Cost Savings)
•    The City of Winnipeg saved over $130 million using CIPP (cured-in-place-pipe) on 145 km of sewer renovation. Another 433 km of pipeline needs rehabilitation with potential cost savings of $390 million 
•    The City of Hamilton has renewed more than 320 km of mainline sewer using CIPP technology and has realized cost avoidances of approximately $200 million 

Environmental Benefits
•    Reduced greenhouse gas emissions
•    Lesser disruption to built and natural environment (50:1 earthwork factor when comparing open trench and trenchless construction)
•    Suited for deeper installations, environmentally sensitive areas, contaminated underground

Social Benefits
•    Minimal disruption to traffic and businesses

Learning Objectives
Upon completion of this course, you will be able to:
•    Demonstrate a broader understanding of the vast array of trenchless methods, processes, and techniques to rehabilitate and replace underground pipelines and utility ducts
•    Describe the limitations and benefits of various trenchless technologies
•    Become familiar with the industry’s best practice guidelines, standards, and specifications
•    Select appropriate rehabilitation and replacement techniques based on factors such as pipeline condition, failure modes, surface and underground conditions, and cost
•    Take advanced courses on trenchless technologies for detailed information on planning, design and construction fundamentals
