Cost-Effective Repairs with Trenchless Sewer Linings

Held Wed. Jan. 20, 2021

Many communities have aging underground utilities that present the risk of failures that could cause costly repairs and service outages. Budgeting to replace these utilities promptly can be challenging as full replacement options include open cut trenching and costly street surface restoration.

One option to reduce the cost of a full sewer replacement is trenchless lining. This method involves installing a new liner inside the existing sewer pipe, essentially acting as a new pipe. Trenchless sewer lining is approximately 60-70% the cost of open cut replacement methods and takes roughly 1/3 of the time vs open cut.

Topics covered include:

  • Understand the benefits of cured-in-place pipe (CIPP) trenchless sewer lining
  • Learn about the limitations of CIPP lining
  • Discuss CIPP lining installation procedures
  • Demonstrate sewer service lining options
