Sanitary Sewer Lining & Televising
Certain City sanitary sewer main line pipes have been inspected and found to be deficient due to age and deterioration.  The pipes will be rehabilitated (or lined) with a trenchless technology called Cured In Place Pipe (CIPP).  CIPP is a polyester felt tube that is impregnated with resin and then cured with hot water or steam to provide a smooth and structurally sound inner lining for the sanitary sewer. 

There are two phases to the lining process.  First is a thorough cleaning of the existing sewer main line.  This should have no impact on homeowners property, although cleaning equipment in the street at access points (sewer manholes) may be observed.  The second phase is the actual lining installation.  This phase of the project is normally completed in one day, within two shifts.  Homeowners will be asked to discontinue use of water for the second portion of the process for an estimated 12 hour period to allow the resin to cure.  Advance notice will be given to those homeowners affected by the installation.

The City will also be inspecting the condition of existing sanitary sewer main lines in the City in certain areas.  This inspection is completed with a remotely operated closed circuit camera vehicle that can travel down the small diameter pipeline and record data as it progresses between access points.

The City has contracted out this work to Visu-Sewer  who will expect to begin this work in April/May with completion by the end of July, 2016.  The sewer lines to be rehabilitated or inspected are shown on this map.
