Sewer Re-lining and Rehabilitation

The contractor, Green Mountain Pipeline is working to rehabilitate and reline the main sewer pipeline along Front Street. The re-lining process is non-invasive and usually takes about 4-6 hours to cure the new pipe. The last of the re-lining of the sewer line on Front Street will continue tomorrow, Wednesday, January 22nd between Gill Street & Parker St. 

Project Information

Relining the existing sewer pipes helps to prevent sewer pipe collapses. The integrity of the existing pipe is converted to PVC technology and provides another 50 year lifespan. This is a cost-effective approach to pipe replacement compared to open trench excavation methods.

From Green Mountain Pipeline's website:

One of the most successful techniques is cured-in-place pipe lining (CIPP), the recognized standard in trenchless technology. When pipes are structurally deteriorated throughout, CIPP lining is the best option for restoring the integrity of the sewer line as well as for eliminating infiltration.

For isolated damage that does not require complete relining, CIPP point repair is the answer for speedy restoration of broken sewers between 4 and 20 feet in length, or longer.

Trenchless CIPP lining of sewers and storm lines offers significant advantages over excavation and replacement, including the following:

• CIPP lining allows for rehabilitation of pipes without disturbance to surface or other utilities.
• CIPP lining produces a seamless, jointless “pipe within a pipe,” minimally reducing the diameter of the original pipe.
• The smooth interior of the liner reduces friction and actually increases flow capacity.
• Service connections are remotely reestablished without digging, reducing inconvenience to residential and commercial customers.
• The finished product has a 50-year design life – the same as that of a brand-new pipe.
• The CIPP inversion process, along with hot air or water curing (hardening), has become the standard in the industry worldwide. The innovative process was invented nearly a half-century ago and provides the highest quality, consistency, and longevity of structural pipe replacement with minimal disruption.
