Reconstruction of Sewer in Hawaii using Trenchless Pipe Jacking

Several sewer projects with HOBAS Pipes were conducted in the last years. One of them was the Wanaao Road/Keolu Drive Reconstruction Sewer with installation of a gravity sewer line, which includes CC-GRP Jacking Pipes installed by Frank Coluccio Construction. Bijan Khamanian, HOBAS Division Manager, explained, “HOBAS Pipes are very well accepted in both Honolulu and Maui Counties. Currently we are supplying 1,341 m of DE 914 mm jacking pipe to the Wanaao Avenue sewer, which connects to the Kalaheo project already in place. In Maui, Pipes diameter 610 mm, PN 10 were used in the construction of Wailuku force main, which was completed in February 2009. As a follow-up, Maui County is also using HOBAS Pipes diameter 1067 mm in the construction of the Wailuku Wastewater Pump Station as well. The largest HOBAS Pipe specified in projects in Hawaii is approximately 1,770 m of 1830 mm for the Beachwalk WWPS and Force Main project in Waikiki, which will go into construction in the fourth quarter of 2009. In addition, projects in Ewa Beach and Pearl City will follow later in 2009 and early 2010.”
