Sewage Advisory: Sewage release to tributary of Fanno Creek in SW Portland

(This is not a Combined Sewer Overflow [CSO] Advisory) 

(January 24, 2020) - Sewage was discharged from a residence in SW Portland, reaching a storm drain leading to an unnamed tributary of Fanno Creek. The release occurred on SW 26th Place near SW Mitchell Court.

The release was discovered at about 4:25 p.m. on January 24 and is ongoing. City crews are working to stop the release and investigate the cause. The amount of sewage released is unconfirmed. 

As a precaution, the public is advised to avoid contact with the creek in that area, between SW 26th and where the tributary meets Fanno Creek at SW Dosch Road and Beaverton Hillsdale Highway for 48 hours because of the possibility of increased bacteria in the water.

This sewage release is not related to the City of Portland's combined sewer overflow control system, which works during rainy weather to prevent overflows of stormwater and sewage to the Willamette River and Columbia Slough.

The Bureau of Environmental Services provides city residents with programs to protect water quality and public health, including wastewater collection and treatment, sewer construction and maintenance, stormwater management, and stream and watershed restoration.
