Department Project Title Project Number
Public Works Wastewater Manhole Replacement and Rehabilitation Project (2022) UT2201
Project Description
This project will replace or rehabilitate roughly 150 wastewater manholes throughout the City. The Department has identified three
different rehabilitation techniques for this project. Each technique brings value to the project based on the need of the manhole that
needs repair. The three techniques include: total reconstruction, cured-in-place fiberglass manhole liner, and sprayed epoxy
manhole liner. After completion of the rehabilitation process of a manhole, the system will experience less inflow/infiltration due to
rainwater and have less risk of a major wastewater issue resulting from a manhole collapse.

Project Justification
Staff completed an inspection of approximately 5,500 manholes in recent years. The inspection assessed each manhole on overall
structural condition, maintenance responsibility, and degree of inflow/infiltration. Each manhole was given a numerical grade on
structural and maintenance condition, with inflow/infiltration being noted as observed. All manholes were inspected by one staff
member so grading would be consistent among all manholes. The manholes that makeup the 660 that need attention were graded
poor and very poor, and were noted to have inflow/infiltration. Inflow/infiltration in the wastewater system causes capacity issues with
the possibility of creating sanitary sewer overflows, and also results in higher wastewater treatment charges. The inspections
revealed that 660 (12%) of the manholes needed some form of replacement or rehabilitation. This project is part of a multi-year
effort to complete all 660 manholes.
