City crews stopped a sewage overflow yesterday evening that occurred from a maintenance hole on the 2500 block of NE Pacific Street.
An estimated 2,100 gallons overflowed and traveled down a slope to I-84 near the 28th Avenue overpass, continuing for about 1,000 feet until it reached a storm drain. The storm drain connects to the Willamette River and a small amount of sewage was detected at the river outfall under the east side of the Burnside Bridge.
The sewage that reached the river is believed to have dissipated overnight, and no advisory is in effect for river users.
The overflow was reported around 4:30 p.m. and crews cleared a blockage and stopped the release around 6:45 p.m. People are asked to obey sewage warning signs posted in the area near NE 28th Avenue and NE Holladay Street.
The Bureau of Environmental Services provides city residents with programs to protect water quality and public health, including wastewater collection and treatment, sewer construction and maintenance, stormwater management, and stream and watershed restoration. www.portlandoregon.gov/bes and @BESPortland.
