Trenchless Pipeline Rehabilitation (WWETT Show 2023)

March 23, 2023

Collection systems are the wastewater utilities largest asset more than the treatment plant. The US Environmental Protection Agency (EPA) estimates that there are over 800,000 miles of mainline sewer pipelines in the US and over 500,000 miles of private sewer service laterals. Each of these conveyance systems is susceptible to structural failure, blockages, and overflows. EPA  estimate that $271 billion is needed to maintain and improve the nation’s wastewater infrastructure. Trenchless technologies have become a major alternative to traditional digging for replacement for pipelines and maintenance holes.

This session will use understandable approach using photo’s, videos, and case histories to cover the following:

1. Problems such as infiltration, exfiltration, roots, corrosion, and structural defects

2. The new advanced technologies available to remove heavy deposits to prepare for pipes for lining

3. Where trenchless technologies can be used.

4. Where trenchless technologies can be used.

     a. Dig & Replace

     b. Trenchless spot repairs.

     c. Slipliners including continuous, sectional, and spiral wound liners.

     d. Cured-in-Place pipe liners e. Folded and Re-formed pipe liners.

Learning Objectives:

1.  Discuss the conditions that increase costs of maintenance and shorten the life of pipelines

2.  Identify applications that require dig and replace and which are candidates for trenchless technology

3.  Discover the trenchless technology options available for pipeline rehabilitation

4.  Discuss the unique equipment required for different trenchless rehabilitation methods
