The annual cured-in-place-pipe sewer lining projects will begin in several locations around town starting Tuesday. You may see cones around trucks accessing sewer lines and notice steam rising from manhole covers.
The 2021 project area includes:
• Dickens Avenue
• Claflin/Denison
• Denison/Hunting
• Stewart Court
• Grandview Terrance
• Wildwood Lane
• Brighton Road
• South Evergreen
• 1600 blk of Houston/Pierre alley
• Amherst/Research
• Bethany Drive
• Highland Drive
• Cherry Hill
• Wildcat Ridge
• Griffith Park
• CICO PARK area
Background:
As sanitary sewers age, they deteriorate. Specifically, cracks appear, and joints separate. Infiltration of water from the ground through these cracks and joints creates external voids, accelerates structural deterioration, and can overload wastewater collection systems and the treatment plant.
The City uses a trenchless pipe rehabilitation technology known as pipe lining. The process rehabilitates and extends the useful life of sewer lines by installing a resin-infused tube into a deteriorated sewer line. This process results in a seamless, jointless "pipe-within-a-pipe" with a smooth, continuous inner surface. The process is fast and cost-effective when compared to sewer replacement.
Additionally, with this process, sewer line problems are solved without digging or significantly disrupting service to sewer customers.
