PORTLAND, Ore. (KOIN 6) — The Portland Water Bureau showed off an innovative, earthquake-resistant iron pipe Tuesday morning.
The pipe has moveable joints and is part of two pilot projects to evaluate the installation of such pipes.
The pipes give the joint flexibility and allow it to move instead of breaking or leaking during an earthquake.
For decades, the Japanese have been using this technology, but it’s just being introduced into the US.
“There is a little higher cost to it,” said David Peters, the principal engineer with PWB, in part because of the “difference in how they connect together.”
Right now, the pipe is being used at Southwest Council Crest Drive and Southwest Northwood Avenue near Hessler Avenue.
