Old Pipe, New Tricks: A Pragmatic Approach to Partially Deteriorated Pipeline Rehab Design

Sign up or log in to save this to your schedule and see who's attending!

This presentation is an overview of the background, alternatives analysis, design approach and construction of the trenchless rehabilitation of a 1.5 mile, 30-inch drinking water pipeline, with an emphasis on the resources and calculations used to design the liner for a “partially deteriorated” host pipe. The benefits in terms of constructability and cost are compared for the “partially deteriorated” versus “fully deteriorated” design requirements. After developing the alternatives analysis, a tight-fit HDPE liner was selected as the rehabilitation method.
The presentation also documents the construction process. This is the first tight-fit HDPE liner installation for a large diameter drinking water pipeline in the state of Utah. This project overview will be interesting for pipeline designers and city asset managers faced with the challenge of rehabilitating deteriorating infrastructure.
