In early 2010, Underground Solution's Fusible C-905® pipe was selected by Kennecott Land Company for a section of the new 30" water main being installed for the Daybreak Development Project in South Jordan, UT. Underground Solutions, Inc. (UGSI) supplied and fused over 1,700 LF of 30" DR25 Fusible C-905® pipe for Harper Contracting, Inc. of Salt Lake City.
Consulting engineer, Hansen, Allen & Luce of Midvale, UT, specified fused thermoplastic pipe where the new 30" water main passes under twin 36" gas mains and a right-of-way under consideration for a future expansion of the Utah Transit Authority (UTA) Trax light rail. Due to the potential leakage and corrosion concerns associated with this location, the owner and engineer wanted a gasket-less, leak-free pipe system.
UGSI's 30" DIPS Fusible C-905® pipe was competitively bid against 36" IPS DR11 HDPE pipe based on equivalent ID (29.3" versus 29.1") and pressure rating (165 psi versus 160 psi). Fusible C-905® pipe was selected by Kennecott Land based on its lower installed cost.
Fusible C-905® pipe allowed Harper to easily connect into 30" butterfly valves and reconnect to the 30" ductile iron sections of the pipeline using standard mechanical connections. A 36" HDPE line would have required 36" to 30" reducers, fused-on flange adapters, and concrete anchors to accommodate increased (4X) thermal expansion and contraction of HDPE as compared to PVC.
Construction was completed in May 2010, with the pipe passing a two-hour, 160 psi pressure test in June.
