City recommends caution for recreational river use

August 12, 2009

Due to the most recent rainstorm, Portland’s combined sewers have overflowed. Portland's Environmental Services advises the public against any recreational activity in the Willamette River during which water could be swallowed.

The public should avoid the Willamette River for 48 hours after the rain has stopped. It is especially important to avoid recreational activities–such as water skiing, jet skiing or swimming–during which water could be swallowed. While health risks from combined sewer overflows (CSOs) are unknown, Environmental Services takes these precautions to protect the public health.

People who fish should wash their hands following contact with the water. Those who choose to eat fish caught in the Willamette River should cook them thoroughly to kill bacteria.

In many areas of Portland, sewage mixes with stormwater runoff in a combined sewer system. When the combined sewer system receives too much runoff, it overflows into the Willamette River. CSOs are contaminated with bacteria from untreated sewage.

Portland is in the 18th year of a 20-year program to improve the city's sewer system. Until the program is complete, overflows of untreated sewage and stormwater will occur during rainstorms, although as the program progresses, CSO volume and the number of outfall pipes that overflow are diminishing.

Sewer work slows traffic on N Denver at N Farragut

August 28, 2009

A sewer construction project is slowing weekday traffic on N Denver Avenue at N Farragut Street. Construction began today (Friday, August 28, 2009) and will take about two weeks to complete. Construction hours are 8:00 a.m. to 3:00 p.m. on weekdays. No construction is scheduled on Saturdays or Sundays.

One lane of traffic is closed on Denver at Farragut during work hours, and motorists should expect delays. All lanes are restored after work hours.
