Pipelines 3 and 4 Relining: State Route 52 to Lake Murray and Pipeline 3 30-inch Interconnect to Lake Murray Control Valve

Pipelines 3 and 4 Relining: State Route 52 to Lake Murray and Pipeline 3 30-inch Interconnect to Lake Murray Control Valve

The proposed project consists of the installation of half-inch thick, 69-inch diameter collapsed welded steel liners in approximately 19,200 linear feet of existing 72-inch-diameter pre-stressed concrete cylinder pipe. While underground activities would occur along the entire reach of the pipeline, above-ground disturbance activities would occur at specified portal locations and staging areas. Pipeline 4 would be accessed at 11 proposed portals extending over approximately 16,600 linear feet. Access to and relining of Pipeline 3 would occur over approximately 2,600 linear feet, through two more portal locations. In addition to the planned portals, access to the pipelines also would take place through up to 18 existing manhole structures and two temporary access shafts along the length of the project alignment.
