FY 2022/23 Sewer Lining Project
August 1, 2023
BACKGROUND AND PROJECT SCOPE
The Engineering and Utilities Divisions identified the need for rehabilitation of existing sewer pipes based on maintenance history and video inspections.
The scope of work for the project includes lining approximately 26,349 lineal feet of aged sewer main lines identified as a priority this year and 84 manholes.
The locations have calcium deposits from groundwater seepage or joints offset by tree roots. The calcium deposits and roots inhibit sewage flow and will be removed prior to lining.
Lining of the pipes is a trenchless operation performed by inserting a liner inside the existing pipe to form a replacement pipe.
