Sewage release to the Willamette near Cathedral Park

Sewage Release Advisory

April 12, 2015

Debris blocking a sewer pipe caused sewage to overflow into the Willamette River Saturday night north of the St. Johns Bridge. Sewage overflowed from an outfall pipe on the east side of the river at the north end of Cathedral Park.

The overflow was reported at 6:34 p.m. Saturday, April 11. Maintenance crews cleared rocks, rags and other debris from a diversion dam to stop the overflow at about 11:30 p.m. Saturday. They estimate that from the time the overflow was detected until it was stopped that about 6,000 gallons of sewage flowed into the river.

The public should avoid contact with the river downstream of Cathedral park through Monday evening because of increased bacteria in the water.

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.
