City maintenance crews are investigating a sewage leak into Ash Creek in southwest Portland near the intersection of SW Knightsbridge Drive and SW Orchid Drive.
Maintenance crews repaired an exposed sewer pipe at this location to stop a previous sewage leak in December 2013. City field crews taking water samples this week found higher than normal bacteria levels in Ash Creek downstream from the pipe.
On Thursday, January 30, crews again temporarily repaired the pipe to stop the new leak. The city is designing a project to permanently repair the pipe. That work has not yet been scheduled.
Because of increased bacteria in the water, the public should avoid contact with Ash Creek in this area through Saturday, February 1.
