30 inch pipe ready for insertion. |
"After meeting with Underground Solutions, it became clear that sliplining with their FPVC pipe product was the best technical approach as well as the most economical trenchless option. It provided a fully structural solution that eliminated future corrosion concerns," Brito said.
Sliplining operations commenced August 17, 2009, near the end of the busy summer season. UGSI provided an on-site construction supervisor to assist C.B. Utility with planning and coordination in order to maintain a tight schedule. To minimize excavation and surface disruption, a 1⁄3-mile segment (1,810 LF) was sliplined in a single pull. In all, six pull-ins were completed. The new 30" line was grouted in place, pressure tested, and connected to the direct bury PVC bell-and-spigot segment of the force main. The line was placed into service on schedule on October 28, 2009.
"Underground Solutions delivered on all their promises by providing a quality product and a very high level of support during planning, engineering, and construction," said Thomas Simbro, P.E., Senior Project Manager with Wright-Pierce in Providence, RI.
