Structural Manhole Rehabilitation - When it is Needed and How to Make it Happen

Abstract

An overview of recommended technical design considerations, installation good practices and inspection strategies to help promote successful trenchless structural manhole rehabilitation in wastewater collection systems is presented. This presentation will discuss the various fully structural trenchless rehabilitation systems that are available, what makes these methodologies structural, and when it is recommended to use these different product types. Differences between semi-structural, interactive lining methods such as bonded resinâ€based polymer coating/ lining systems including epoxies, polyurethanes, poly-ureas, as well as cementitious materials and geopolymers will be explained and compared with fully structural, independent manhole rehabilitation technologies in a neutral, non-commercial manner. Common problems that can be avoided through proper planning, design, product specification, installation and appropriate quality control procedures will be covered. The importance of performing QA/QC inspections throughout the rehabilitation process and what to look for when performing manhole condition assessment evaluations, with emphasis on implementation of proper surface preparation techniques will be discussed. Design methodologies, product selection, specification development, applicable inspection strategies, and technical standards will be referenced. Structural manhole rehabilitation case studies in Colorado and New Mexico will be introduced and discussed throughout the presentation, with focus on lessons learned for each project.

This paper was presented at the WEF Collection Systems Conference, June 27-30, 2023.
