The intent of this project is to construct a new welded steel, ductile iron or concrete cylinder pipe material raw watre transmission pipeline to convey the raw water that currently flows through the existing Clipper Creek Siphon. This existing pipeline was constructed using Techite pipe: a reinforced plastic mortar pipe material manufactured on the 1970s. Approximately 5,400 ft of Techite in the Cascade Shores Siphon upstream of the Clipper Creek Siphon was removed and replaced with concrete cylinder pipe in the late 1970s after a significant pipe rupture. The remainder of the Cascade Shores Siphon was replaced with the Cascade Flume Replacement Project in 2002, with the Techite materials replaced with welded steel pipe.
