ADS HDPE Sewer Pipe: I-90, Third Lake Washington Bridge Maintenance Facility

The construction and pressure testing of a field installation of ADS HDPE corrugated PVC sewer pipe is documented in this report. The ADS HDPE pipe was installed on a project located on I-90 underneath the west approach to the Third Lake Washington Floating Bridge. The ADS HDPE pipe is a double walled (smooth interior) corrugated polyethylene pipe meeting the requirements of AASHTO M 294. The use of the ADS pipe saved time and money by not having to use a backhoe to set the pipe sections. A $507.50 credit was received by the Washington State Department of Transportation for the use of the ADS pipe in lieu of plain concrete pipe.
