Sewage Advisory: Broken sewer pipe discharges to tributary of Fanno Creek in SW Portland

(November 11, 2020) – Crews responding to a report of a sewage odor found a broken pipe this evening that was discharging to an unnamed tributary of Trillium Creek, which flows into Fanno Creek in Southwest Portland.

The break occurred near the 5000 block of SW Dosch Park Lane. The sewage release is ongoing. Crews are working to divert the sewage flow while repairs are being made.

Warning signs have been posted in the area. As a precaution, the public is advised to avoid contact with the creek at Dosch Park Lane, the creek system downstream of the intersection of SW Dosch Road and Boundary Street, and Fanno Creek downstream of the intersection of SW Dosch Road and Beaverton-Hillsdale Highway through the weekend because of the possibility of increased bacteria in the water.

The cause is unknown and is being investigated. If you experience or see a sewer overflow, call the City of Portland’s 24/7 hotline: 503-823-1700.  

Environmental Services has ongoing construction projects to repair and replace aging sewer and stormwater infrastructure to protect public health, property and the environment. To see current projects, visit
