Pipeline Inspection Services are Necessary to City's Sewer Maintenance Program Pipeline inspection services have proven invaluable in locating problems and answering questions that arise in the normal maintenance of the City's sewers along with ongoing condition assessment. Major work items are detailed below: 1. Sewer Line Inspections: This work is performed through the insertion of a camera that is driven or pulled through sewer lines in order to determine the condition of the line. This information assists staff in preparing improvement projects or identifying maintenance needs. As in 2008, the emphasis on televising will be large diameter critical sewers. 2. Manhole Inspections: Manholes are often a weak link in the sewer system in that they are direct access points to the sewer system. Many manholes are located on streets and are subject to traffic loads and heavy storm water inflow. These forces often have a significant effect on the structural integrity of a manhole and the sewer system in general. A significant Page � 1
