GRP Wastewater and Storm Water Pipe System Solutions for Beaverton
Beaverton in Oregon is a city that devotes 400 ha to 100 parks, so one is within 800 m of every home. With this emphasis on green space, Clean Water Services, the regional wastewater and storm water utility, set the highest priority on reliability in planning a sewer upgrade through Tualatin Hills Park and Recreation District’s 90 ha nature park. According to Steve Lampert, one of Clean Water Services’ project managers, “the main consideration was we didn’t want to have to go back out to the wetlands to make repairs.” A corrosion resistant product that would remain leak-free for years to come was exactly what they were looking for. The specifications included 2.5 km of pipe – approximately 0.5 km DN 1200, about 1 km of DN 1500 and around 0.5 km of DN 1700. The alternatives were profile wall polyethylene and HOBAS® CC-GRP Pipe Systems. Neither of these is affected by hydrogen sulfide. The DN 1200 HOBAS® Manhole Risers were reduced to a standard DN 600 top. HOBAS® also made the manhole covers, which were attached with a gasket and bolts ensuring they would be watertight as the summer water levels rise. “HOBAS® supplied a complete package,” Lampert continued. By providing the pipe, manhole tee bases, risers and lids, HOBAS® CC-GRP Pipe Systems make jobs convenient for the contractor.
