Sanitary Sewer Overflows (SSOs)

Sanitary Sewer Overflows

On occasion, debris and other obstructions in sewer lines can cause sewage releases to Portland waterways. Information on current sanitary sewer overflows is posted on this page. There is currently no sanitary sewer overflow reported in Portland.

If a sanitary sewer overflow affects a Portland stream, Environmental Services issues an advisory to Portland media and places warning signs at the point of the overflow and at public access points downstream. The advisory remains in effect and the signs remain in place for 48 hours after the overflow stops.
