Analysis:
The Engineering and Utilities Division coordinate the need for rehabilitation of existing sewer pipes based on maintenance history and video inspection. The scope of work for the project includes lining approximately 25,000 lineal feet of aged sewer main lines identified as a priority this year. The locations would benefit from lining as the existing pipes are either lined with calcium deposits from groundwater seepage through minor cracks and joints, or have joints offset by tree roots from adjacent mature trees located on parkways. These deposits and roots, which inhibit flow, will be removed prior to lining. Lining of the pipes is a trenchless operation performed by inserting a liner inside the existing pipe to fully rehabilitate the existing pipe.
