PORTLAND — An earthquake resistant water pipe widely used in Japan is being given a test drive by the Portland Water Bureau. Its official name is the Earthquake Resistant Ductile Iron pipe. It has moveable joints and has been used in Japan for 45 years with zero failures in earthquakes.
Water Bureau engineer David Peters says the pipe is being installed in two locations in the West Hills and is being funded by the bureau’s maitenence replacement program. This pilot project comes as the bureau is conducting a seismic study of the city’s water main system.
“We’re just excited to be able to try this product out. We have areas in Portland where we have concerns about land movement and a product like this would be an excellent product to prevent pipes from breaking or coming apart when the land does move,” said Peters.
