Electrical malfunction causes weekend sewage spill at Willamette pump station

A pump station located in West Linn, operated by Clackamas County Water Environment Services (WES), on behalf of the Tri-City Service District, spilled approximately 300,000 gallons of sewage into the Willamette River on Sunday.   The cause was an electrical problem that led to the failure of the plant’s pumps.  Power was restored and repairs were made within two hours by WES staff.

The Oregon Department of Environmental Quality (DEQ), Oregon Emergency Response and Portland General Electric were notified of the incident.  As a precaution, signs have been placed near the site.  The public should avoid contact with river water near the site until the signs are removed.

The Tri-City Service District provides wastewater treatment services to the cities of Gladstone, Oregon City and West Linn.
