Whatcom Creek Sewer Trunk Main

​​Project Overview:  EU-0182

This project is to re-line the existing sewer trunk main along Whatcom Creek from Nevada right of way west to the intersection of Holly and Champion. The existing main was installed in 1909.  The goal of the project is to extend the life of the life of the sewer main by re-lining the interior.  Video of the interior of the main verified there is damage to the pipe including holes and cracks.  This project will complete some spot repair as well as install some new manholes to help facilitate maintenance.  The sewer main is not a traditional pipe; it is a custom brick and concrete, egg-shaped conveyance system.  Re-lining this type of structure will require custom shaping of the liner.  The sewer main is adjacent to, and crosses under Whatcom Creek, so ensuring that Whatcom Creek will not be disturbed during construction will be a challenge.  The largest challenge will be to insure the sewer main is operating at capacity during the re-lining process.  The sewer main services a large section of the City and cannot be taken off-line.
