This project includes rehabilitation of 111 active sanitary sewer manholes or structures, identified by the Large Diameter Sanitary Sewer Condition Assessment Report, with a NASSCO Structural Condition Grade 4 or higher. Rehabilitation may include installation of corrosion coating systems, structural inserts and liner repairs in all parts of the existing manholes. There will be bypass pumping for select manholes identified and use of small diameter flow through plugs may need to be utilized to complete the work.
