A total of 3 km pressure pipe DN 2400 and FW couplings are being installed for the project. The HOBAS pressure pipes used have pressure class PN 2-5 and stiffness class SN 5000.
The CC-GRP pipeline is being installed in three phases using open trench installation. The first phase is now complete, and saw installation of HOBAS pipes beneath a river’s groundwater level. Phase two is currently under construction with completion scheduled for June 2009, and the final phase is scheduled to end in September.
