PORTLAND, Ore. (AP) A sewer pipe in Northeast Portland leaked an estimated 1,000 gallons (3785 liters) of untreated sewer water into an embankment.
The Oregonian/OregonLive reports the Portland Bureau of Environmental Services plugged the leak Saturday near I-84 and Northeast 21st Avenue.
The 1,000 gallons is a rough estimate.
Bureau spokeswoman Diane Dulken says crews believe the pipe has seeped for some time and it's impossible to determine the exact volume.
A complaint of a foul odor prompted a search.
The bureau oversees 2,500 miles (4023 kilometers) of sewer and stormwater pipe. Dulken says a third of the city's sewer pipes are 80 years old or older.
The bureau is designing a project to make urgent repairs to 3,600 feet (1097 meters) of sewer pipes in downtown Portland at high risk of collapse.
