Summary of Summary of November 17th Meeting Wilsonville High Priority Utility Repair Project

First the City looked at our system to prioritize Severity (Ie Sewage) and Cost Saving Groupings. From this survey it was decided to Spot Repair Manhole to Manhole the bad areas.

There are three options to repair our system

  1. Cured in place pipe (CiPP) which means that a material flowed into the pipe will seal the pipe (lining the pipe)
  2. Pipe Bursting – they will not be doing this
  3. Open Excavation and Replacement – A brand new pipe (most expensive)
    1. Adding Catch Basins as needed (this happen all areas of construction)
