Advisory: Sewage release to tributary of Tanner Creek at 3263 SW Cascade Terrace

Sanitary Sewage Release Advisory (this is NOT a Combined Sewer Overflow [CSO] Advisory)

(February 14, 2019) – Sewage was released from a City-owned pump station at 3263 SW Cascade Terrace. The sewage discharged into a stormwater catch basin for a tributary of Tanner Creek. 

The volume of the release is estimated at approximately 2,700 gallons. The release began around 5:45 a.m. City crews are onsite working to stop the release and conduct cleanup. An investigation of the cause of the release is ongoing. 

The public should obey the warning signs in the area and avoid contact with the tributary to Tanner Creek for 48 hours.

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

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. and @BESPortland.
