United Water Rehabilitates Steel Water Main in Secaucus, NJ: 2,680 LF of Fusible C-905® Pipe Sliplined in a Single Pull
United Water of Oradell, NJ was faced with rehabilitating a half-mile section of an existing 18" steel water main under heavily traveled Route 3 in Secaucus, NJ. The line, mounted on the underside of the Hackensack Bridge, had developed leaks at the joints.
Design considerations required a solution that could utilize the existing line in order to minimize activity in difficult to access locations under the bridge. With an inside diameter of 17.25" on the failing pipeline, maximizing flow while providing a 235 psi maximum operating pressure was a primary objective. Thermal expansion and contraction considerations were also critical due to the exposed nature of the suspended pipeline. After considering several design options, United Water elected to slipline using 14" DR18 Fusible C-905® pipe which could be pulled into the existing water main in a single 2,680 LF pull.
The high pull strength, large inside diameter, and favorable expansion/contraction characteristics of Fusible PVC™ pipe were instrumental in United Water's decision to slipline with Fusible C-905® pipe. Owen Blake of United Water commented: "When faced with a similar situation in the future, United Water would once again utilize Fusible PVC™ pipe technology."

Rick DeNicola, General Superintendent and Project Manager with J. Fletcher Creamer & Son, commented: "Due to the project's close proximity to the Lincoln Tunnel, the short work hours were a major obstacle. Using Fusible PVC™ pipe allowed us to fuse the entire pipe string together during the daytime hours and install the 2,680 LF in one pull. The pipe was extremely flexible which made for a trouble-free installation. The liner was installed in a single, six-hour road closure."
This is the second slipline rehabilitation project completed by United Water using Fusible PVC™ pipe technology, following the successful 3,510 LF slipline of a failed 16" cast iron water main under the Susquehanna River near Harrisburg, PA in 2006.
