Pamplin Media Group - Portland s new water pipes expected to last 250 years

Portland s new water pipes expected to last 250 years July 18 2021 Despite difficult working conditions caused by the COVID-19 pandemic, the Portland Water Bureau managed to replace more water pipes than ever. In recent years, American infrastructure has sometimes been characterized as crumbling and out of date. According to the American Road and Transportation Builders Association, four out of 10 bridges in the United States need to be replaced or repaired, including one in three bridges on the Interstate Highway System, at an estimated cost of $41.8 billion. One place where infrastructure replacement is ahead of the game is Portland and its water pipes.

OSU Helps PDX Prepare For The Big One

Armin Stuedlein led the project, which involved three days of test detonations at the airport in 40- and 90-foot-deep blast casings. By studying the series of controlled blasts, researchers could determine how the sand and silt soils underlying the airport would respond to a “megathrust earthquake” and what ground improvements are needed to prevent liquefaction and keep the runway intact.
