News Release: Sewage overflows from manhole on SW Barbur Boulevard towards Stephens Creek

Sewer maintenance crews responded this afternoon to reports of sewage flowing from a manhole on a sidewalk at SW Barbur Boulevard near SW Bertha Boulevard.

NEWS RELEASE: SEWAGE OVERFLOWS FROM MANHOLE ON SW BARBUR BOULEVARD TOWARDS STEPHENS CREEK

News Release from Portland Bureau of Environmental Services
Posted on FlashAlert: January 18th, 2017 5:12 PM

Sanitary Sewer Overflow (SSO) Advisory
(this is not a combined sewer overflow [CSO] advisory)

Sewer maintenance crews responded this afternoon to reports of sewage flowing from a manhole on a sidewalk at SW Barbur Boulevard near SW Bertha Boulevard.
Field crews estimated that 4,000 gallons of sewage overflowed onto the ground and into the street and down a storm drain that feeds into Stephens Creek before emptying into the Willamette River.
Crews attempting to unblock the sewage line found instead that the cause was weather-related: An influx of water had exceeded the sewer line's capacity and the excess was being released through the manhole. It is unknown at this time if the release has stopped.
Environmental Services crews posted warning signs in the area. Crews will return to the location tomorrow.
In addition, as a precaution, the public is advised to avoid contact with Stephens Creek for at least 48 hours because of the possibility of increased bacteria in the water.
Unlike this event, most sewage overflows are caused by blockages. 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 sewage overflows.

CSO Advisory: Snowmelt and rain lead to combined sewer overflow (CSO) to the Willamette River

Snowmelt combined with heavy rain caused Portland's combined sewer system to overflow to the Willamette River this afternoon at several locations.

CSO ADVISORY: SNOWMELT AND RAIN LEAD TO COMBINED SEWER OVERFLOW (CSO) TO THE WILLAMETTE RIVER

News Release from Portland Bureau of Environmental Services
Posted on FlashAlert: January 18th, 2017 4:13 PM

Snowmelt combined with heavy rain caused Portland's combined sewer system to overflow to the Willamette River this afternoon at several locations.
Because of increased bacteria in the water, the public should avoid contact with the Willamette River for 48 hours after the CSO event ends. The event began at 1:10 p.m. and is still continuing. The volume is not yet known.
The overflows begin at the outfall near the Ross Island Bridge and extend downstream. Several outfalls are affected.
Portland's combined sewer system carries sewage and stormwater runoff in the same pipes. In December 2011, Portland completed a 20-year program of sewer improvements, including constructing big pipes on both sides of the Willamette River and along the Columbia Slough. The improvements eliminate 99% of CSOs from the slough and 94% from the river.
During heavy storms, the big pipes store large quantities of stormwater and sewage while pumping it to the Columbia Boulevard Wastewater Treatment Plant. During very heavy storms, some combined sewage can overflow. A combined sewer overflow is about 80% stormwater and 20% sanitary sewage.
Before the city completed the CSO control program, combined sewers overflowed an average of 50 times a year. Today, the combined system overflows to the Willamette River an average of four times per winter and once every three summers.
This is the second CSO this 2016-2017 winter season. The previous overflow occurred on Thanksgiving Day.
