CIPP Trenchless Sewer Main Replacement

Project description 

Cured in place pipe (CIPP) lining is a trenchless method of sewer rehabilitation. This process requires little to no digging and it requires significantly less time to complete than other repair methods. CIPP involves inserting a flexible liner inside the existing pipeline. inflating the liner, and exposing it to heat to dry and harden the resin inside. The liner essentially forms a smooth surface inside of the existing pipe, restoring it to near-new condition.

What to expect

Residents will be asked to limit water and sewer use during the lining process. These actions are important because property connections to the public sewer will be temporarily sealed off during the pipe lining. Using less water is necessary to prevent water from filling up a private sewer line and backing up into a home or business. Residents should expect these operations to last between 4-8 hours. Residents will be notified no less than 24 hours prior to lining activities beginning. Normal water and sewer use may resume once crews have left the work zone.
Unpleasant odors may be experienced by residents during the lining process. This smell will dissipate once the lining process is complete. A tip to prevent the resin odor from entering the home or business through the sewer is to fill any floor drains and infrequently used sinks with a small amount of water. This will collect in the bend in the drain, called a "P-trap", and block odors from the sewer. In the case of the resin odor already being in the home or business, cover floor drains and open windows to allow ventilation. If the odor continues, phone or email the contacts on the contractor's construction notice.
