This webcast will provide collection system engineers and owners with the tools they need to perform successful manhole rehabilitation projects. The first portion of the webcast will provide a background in manhole assessment and selection of appropriate rehabilitation technologies. We will begin with a description of the initial condition assessment phase based on NASSCO’s Manhole Assessment and Certification Program (MACP). This will be followed by descriptions of rehabilitation technologies from industry experts, including grout, cementitious, polymers, and chimney rehabilitation.

The second portion of the webcast will focus on design, specifications, and quality. We will describe the use of NASSCO’s recently completed standard specifications as a guideline for your project specifications. The webcast will wrap up with an overview of the post rehabilitation inspection and testing that should be required for various technologies.
