Relining of Jordan Aqueduct, Reach 3by Douglas H. Wegener, Bureau of Reclamation, United States,
Abstract: As pipelines approach their life expectancy, they may need to be replaced. Or in some instances, replacement is needed much sooner due to defective pipe. Normal replacement operations require reexcavating the existing pipeline, removing it, and installing new pipe. In some instances this open trench excavation may not be desirable. Thus, the need for alternative procedures. One such procedure is the relining of existing pipelines in place, thus rejuvinating it to new pipeline status. This procedure was done on the Jordan Aqueduct, Reach 3. The decision was made by the Bureau of Reclamation to reline the existing pipeline instead of replacing it, thus reducing environmental disturbances in a highly urbanized area. A steel liner was inserted inside the existing pipeline. The annular space between the two pipes was grouted to form a composite section pipeline. The inside of the new steel liner was then cement-mortar lined in place. The pipeline was placed back in service and has performed satisfactory.
