The objective of sewer rehabilitation is to:

• Ensure a sewer’s structural integrity
• Limit the loss of conveyance and treatment capacity due to excessive I&I
• Limit the potential for groundwater contamination due to exfiltration

The most basic solution is to excavate a pipe and replace it. However, doing so is expensive and causes significant disruptions for traffic on roads (under which most sewer mains are installed), and to residential customers. For these reasons, less-disruptive trenchless technologies are preferred for sewer rehab. These include pipe bursting, slip-lining and pipe insertion, and CIPP.
