Structural Capabilities of No-Dig Manhole Rehabilitation (Report + Tool + User Manual)

This project investigated the structural capabilities of commonly used manhole rehabilitation materials and methods via literature review, case study compilation, lab tests on mechanical strength, and computational modeling. It provides a classification for manhole rehabilitation techniques based on their structural capabilities (i.e., fully, semi-, or non-structural). The report provides decision support to wastewater and stormwater utility personnel and consulting engineers on material and method selection alternatives for wastewater rehabilitation projects, thereby reducing sanitary sewer overflows and their effects on the environment. Included is an Access-based decision support tool which can be used to choose structural class and construction methods appropriate for a manhole considered for rehabilitation.
