Will 2020 Be The First Sewage-Free Year For The Willamette River?

Will 2020 Be The First Sewage-Free Year For The Willamette River?
In a year where good news seems scarce, Portland may reach a historic milestone for Willamette River water quality. The year 2020 is on track to be the first in modern history with zero combined sewer overflows to the river.
That’s a triumph of Portland’s investment in the Big Pipe Project, the $1.4B 20-year-long public infrastructure project that dramatically reduced such incidents and changed Portland’s relationship with its river. Overflows that used to be common - occurring about 50 times a rainy season, sometimes for days on end - now are rare. Environmental Services projects about four overflows per rainy season, a 94 percent reduction.
