Rain Overflows Portland's Big Pipe, Putting Sewage In River

Portland’s sewage overflowed into the Willamette River for the third time this year during Wednesday’s rain storm.

The city’s Environmental Services Bureau says it was just too much, despite the $1.4 billion Big Pipe project that was completed three years ago.

Spokesman Linc Mann tells KATU that the project has been a success in controlling sewer overflows but it can’t prevent them all.

He says there used to be 50 overflows a year. There have been just 10 since the 2011 project.

Wednesday’s storm dropped 1.8 inches of rain at Portland International Airport, breaking the old mark of 1.31 inches set in 1951.
