In a statement released shortly after 11:00 a.m. Thursday, the City of Sutherlin says an inundation of storm water caused a raw sewage overflow into Cook Creek from Sunday to Tuesday.
Due to 2.70 inches of rainfall and 10 inches of snow, the City of Sutherlin wastewater system began overflowing raw sewage and storm water to Cook Creek at approximately 11:15 a.m. on Sunday.
The overflow reportedly stopped on Tuesday at about 7:15 a.m.
As required, Department of Environmental Quality and Oregon Emergency Response have been notified.
City staff believes the risk to human health is low.
According to Waste Water Treatment Plant Supervisor, John Bachman, “by the time it hits the creek, it gets diluted to the point that we feel the danger level isn’t elevated to any danger level that doesn’t already exist from what’s already coming down the creek.”
City of Sutherlin’s Wastewater Treatment Plant and collection systems surcharged during this event due to inflow and infiltration into the collection system. To correct the problem the City has completed several maintenance projects such as sewer pipe lining and manhole rehabilitation.
The overflow has reportedly been cleaned up.
The notice delay was due to the loss of power and internet at Sutherlin City offices. For more information contact the City of Sutherlin.
