Digging it up can be particularly costly, as well as disruptive to residential customers and road traffic. To avoid this, methods have emerged allowing sewers to be fixed without excavation. These methods are referred to collectively as “trenchless technologies.”

No two sewers pipes are alike. Many differ significantly in terms of size (both diameter and length), pipe material, effluent characteristics, service connections, soil composition and water table. Pipes also fail in different ways: they can crack, leak, settle, erode, corrode and collapse. These failures can be localized, or they can be pervasive. Moreover, the goal of rehabilitation can vary to include:

  • Restoring structural integrity,
  • Stopping groundwater infiltration, and/or
  • Stopping the exfiltration (leakage) of sewage into the environment.

Such a wide range of considerations has spawned an array of trenchless technologies, each suited to a particular set of conditions and challenges.

For newcomers to the sewer industry, the multitude of trenchless technologies can be confusing. Still, making a good choice depends on understanding all the options, including the process, benefits and limitations of each trenchless rehab method. Common methods include:

  • Pipe Bursting
  • Slip-Lining
  • CIPP
  • Deform/Reform
  • Mechanical Point Repair
  • Chemical Grouting
  • Cement Grout
  • Spray-Lining
  • Pipe Reaming
  • Rerounding
