100 gallons of sewage spills into Southwest Portland stream
Sewer maintenance crews responded to a broken pipe in the Marquam Nature Park Friday morning, and are working to clean up about 100 gallons of sewage that is pooling in a self-contained stream between the Shelter Loop and Sunnyside trails.
The Portland Bureau of Environmental Services advises people to follow warning signs posted in the area and remain on trails.
The agency says over one-third of Portland's more than 2,500 miles of sewer pipes are over 80 years old. Pipes that fail or become blocked with grease, tree roots and debris can cause overflows.
