The NJDOT engineers were challenged with designing a method of enhancing the structural integrity of the PVSC's 108" combination sewer main in Clifton, NJ to accommodate a major road expansion and bridge replacement project to cross the Passaic River on Rt. 3 leading to the new Meadowlands Sports Complex and the Lincoln Tunnel.

The costly process of bypassing the sewer flow was believed (by project engineers) to be necessary for the success of this project. After 7 years of planning, the DOT reluctantly added an alternative to slip-line the pipe using 99" FRP pipe installed under live flow. Spiniello was the only company out of the 13 bidders who was confident enough to bid the project without the elaborate, disruptive bypass pumping system. This decision saved the State of NJ over $1.4M and was the key component to Spiniello being awarded the project.

The project was successfully executed under very challenging weather and high flow conditions in the winter of early 2010. The NJDOT and PVSC closely monitored the project during construction. They realized that this technology has real value for the future of the rehabilitation of our wastewater infrastructure.
