The area was temporarily closed to traffic while crews accessed and addressed the overflow. Maintenance crews cleared a sewer line blockage to stop the sewage release. The release was reported at 11 p.m. and was stopped at 12:15 a.m. Thursday morning. Crews worked through the night to restore sewer service, disinfect the right of way, and reopen the area to the public in time for the morning commute.
The cause of this incident was a grease plug obstructing the sanitary sewer main. Sewage overflows often are preventable. Pipes that become blocked with grease, tree roots, and debris are the most common cause of sewage overflows.
Environmental Services advises the public to prevent clogs and protect public health, property, and our environment by following these tips:
The City of Portland treats an average of 70 million gallons of wastewater each day. More than one-third of Portland’s more than 2,500 miles of sewer pipes are over 80 years old. Pipes that fail or become blocked with grease, tree roots, and debris can cause sewage overflows.
To report sewage odors, which may indicate a sewage release, call the City’s maintenance hotline at 503-823-1700. That line is operated all hours, all days.
