Municipal underground infrastructure is becoming increasingly congested with the addition of utilities ranging from sewers, watermains, gas, power, telephone and other pipeline networks. Coordinating a repair to deteriorated sewer and watermain networks has become a major undertaking. With the potential for damage to other utilities, the inconvenience to the public and the high cost of restoration, trenchless rehabilitation of sewer and watermains has become the preferred construction method in urban areas.

Course Outline

As one of the core courses in the epCIP program, the Trenchless Rehabilitation course will provide in-depth knowledge of rehabilitation selection, techniques and design methods. Upon completion of this course the civil infrastructure professional will acquire a comprehensive foundation of knowledge and skills relating to:

  • Selection criteria – rehabilitation versus new construction, structural versus non-structural, localized versus full length, bypassing, direct and social costs and environmental impacts.
  • Design methods – non-structural, structural (flexible and rigid liners), site investigation, risk assessment and life cycle costing.
  • Techniques – repairing mainlines, laterals and maintenance holes, both structural and non-structural methods and pipe bursting.
  • Construction – specification considerations, site preparation, installation and reinstatement.
  • QA/QC – field and test coupons, epoxy resin mixtures, etc.

Key benefits to the student:

Completion of the Trenchless Rehabilitation course will enable the student to:

  • Confidently manage situations that arise both in a maintenance program, or an emergency situation.
  • Assess repair needs and implement an appropriate rehabilitation solution.
  • Information requirements for trenchless rehabilitation design and construction.
  • Attain professional training credits.

Key benefits to the employer:

  • Having staff with the ability to assess and coordinate rehabilitation projects effectively.
  • Being able to approach contracts with the latest Best Practices procedures developed in this field.
  • Appropriate and cost effective selection of pipeline rehabilitation methods.
  • Reduced pavement restoration and maintenance costs.
  • Reduced disturbance to adjacent utilities and services.
  • Staff that understand trenchless rehabilitation methods that minimize traffic congestion.
  • Improved infrastructure performance.
  • More knowledgeable staff (HQP) that understand available trenchless rehabilitation methods.
  • Employee training credits that meet or exceed legislated requirements.
