Novi Sanitary Manhole Rehabilitation
This project consists of multi-neighborhood manhole rehabilitation requiring an extensive investigation process. Spalding DeDecker (SD) inspected existing sanitary sewer manholes for inflow and infiltration and general overall condition of approximately 150 manhole structures.
Following a system adopted from NASSCO’s MACP, each structure was accessed from the surface and individually inspected. SD provided extensive documentation and photos to show any unwanted water infiltration or structural damage.
After the inspection, plans and bid documents were prepared to rehabilitate the manholes as needed. The work includes new covers, wrapping the exterior of the cones, re-pointing the structures, and interior coating to control excessive inflow and infiltration.
