Pollution Engineering - February 2009 - (Page 38) SLIPLINING As with many projects, there were obstacles to overcome. “We have a lot of experience in rehab and have tackled some pretty tough projects. Sliplining pipe of this size is not like sliplining with smaller sizes. This was an uncommon project, the first time it was done. The project went well and we made good production putting the pipe in,” said Tom Gillis, project superintendent with Kenny. The sewer line under contract had a semielliptical cross section of approximately 10 feet by 10 feet. Kenny bid the project planning to rehabilitate all 7,000 linear feet with 110-inch diameter pipe. Upon closer analysis of the existing sewer, they found that a reduction in liner diameter in several locations was necessary because the existing sewer was not round or straight and had many old repairs. Some Serious “ Access to the sewer was limited because of the five to 26-foot cover depth under the existing infrastructure, including roads and a railway. Maximizing ID “The first 2,000 linear feet of sliplining had been completed using 110-inch flush reline pipe, which has an O.D. of 114 inches,” said Gillis. “Conditions we discovered when the job was started prompted a revaluation of the original design and resulted in the installation of 104-inch pipe with an O.D. of 108 inches to be used for the remainder of the rehabilitation work.” The pipe manufacturer delivered a flush-joint sliplining pipe that had precisely the same diameter at the pipe barrel and the bell joint; this also facilitated installation. Most sliplining projects are located in congested areas with limited access to the line. In this case, that was so true that immediately accessible pipe storage was not possible.
