Portland Sewers


This video is not currently available. We apologize for any inconvenience.

The sewers of Portland are designed to transfer both household wastewater and rainwater to a treatment system. But when the rainfall is too heavy, the pipes can’t handle the flow, and rainwater and untreated sewage are dumped directly into the Willamette River.

First Broadcast: 2003
Producer: Jim Newman
