Summary
Replacing the existing 6" asbestos cement force main serving Pumping Station No. 4 with a new 6" CLDIP and HDPE force main. Installation will be completed using both open cut and directional drilling methods. A key portion of the work involves a long directional drill under the New Jersey Turnpike, I-295, and the Salem Canal, with the new 6-inch carrier pipe installed inside 12" HDPE casing pipe using casing spacers. The project also includes new ductile iron yard piping at the pump station, air release and bypass vaults, a new terminal doghouse manhole, and full restoration of all disturbed areas. A bypass pumping setup will be required to keep the system in operation during the switchover.
