Wastewater overflow into the Willamette River

Clackamas Water Environment Services (WES) personnel responded to an overflow of wastewater into the Willamette River early Thursday morning. 

The overflow occurred at 7:37 a.m. at the Bolton Pump Station in West Linn, and lasted 13 minutes. Officials said there was a pumping failure, which was quickly resolved. 

WES personnel placed signs informing area residents about the spill in the vicinity of the incident. The Oregon Emergency Response System has been notified.
