Seattle Public Utilities (SPU) has completed two projects using lining as a method for rehabilitating old pipelines. Less roadway restoration is a primary benefit. However, to make it work, there are other things that need to be considered: the installation of temporary watermains, traffic impacts, noise, and scheduling. All are a factor in overall project success. SPU will share their unforeseen challenges and lessons learned.
