Regardless if a manhole is newly installed or has been rehabilitated, the manhole needs to be inspected to ensure that the installation was correctly performed, and the design criteria and objectives are met. Manholes, our windows to the sanitary sewer collection systems, are basically simple structures and are often overlooked for proper inspections. This presentation will cover various methodologies to inspect new and rehabilitated manholes (and structures). The methods that will be covered in this presentation include: visual inspection during installation/application; visual inspection post installation/application; pull tests; vacuum (water) tests; and spark tests.
