Sewer maintenance crews responded Sunday afternoon, August 20, to the report of sewage flowing from a manhole at the southwest corner of Sellwood Riverfront Park, near S.E. Spokane Street. An unknown quantity of sewage discharged from a manhole and was contained and cleaned up by sewer maintenance crews.
The flow did NOT reach the Willamette River, according to preliminary field reports; however a public warning was posted at the site.
According to the Bureau of Environmental services, the cause was unknown; pipes that become blocked with grease, tree roots, and debris are the most common cause of sewage overflows. Environmental Services advises the public not to flush anything other than waste and toilet paper, and to not put anything down storm drains, which are intended for rainfall only.
