Just after 8:30 AM this morning, Portland Water Bureau Maintenance & Construction crews successfully excavated and exposed the water main break, which revealed that the 20-inch cast iron main—which was installed in 1931— had broken horizontally down the length of the pipe. 

  

Throughout the morning and into this afternoon, Water Bureau crews cut out and replaced an estimated 16-foot section of damaged pipe.  Crews are now working to backfill the excavation with several dump truck loads of rock.

The water main break at SE 20th Avenue at SE Powell Boulevard has caused water to accumulate on SE Powell Boulevard beneath the SE 17th Avenue overpass. The Oregon Department of Transportation (ODOT) has closed SE Powell Boulevard between SE 14th and SE 20th due to the slowly draining standing water.

Traffic will be detoured as SE Powell Boulevard will be closed eastbound at SE 14th Avenue and westbound at SE 20th Avenue. ODOT estimates that SE Powell Boulevard will reopen within the next two hours.

Update 6:28 AM
Sunday, February 9, 2014 

The water shutdown is complete. Work is estimated to take all day and into tonight.

Customers May Experience Discolored Water Due to the Water Main Break at SE Powell Boulevard at SE 20th Avenue
When the water from your faucet is discolored this indicates a disturbance in the water main. Since Portland is an unfiltered water system, there is a fine layer of sediment on the bottom of the water mains that can be stirred up.  Hydraulic disturbances caused by hydrant use, valve turning, main breaks or adjacent construction can stir up these sediments and cause the water to be discolored. Usually the water will clear on its own within a few hours. If your water is discolored:

  • The water has been been treated and is safe to drink.  
  • If there are particles or sediment in the water, use should be avoided. It may not be harmful but sediments can clog aerators and home filters.  It is fine to use this water to flush toilets.
  • Avoid using hot water until the pipes clear. That avoids drawing dirty water into your hot water tank.
  • After an hour or so, run the cold water for several minutes to see if it is clear. When one faucet runs clear, run the cold water through all home faucets until each is clear. This step will eliminate the dirty water that may have been drawn into your pipes.
  • If this does not go away in a few hours, you should call the Water Quality Line at 503-823-7525.

The Portland Water Bureau reports a water main break at SE Powell Boulevard at SE 20th Avenue.

At 3:30 am this morning, a 20-inch in diameter cast iron pipe installed in 1931 ruptured, causing water to flow into the immediate area. 

Water Bureau crews are onsite shutting down water. It is unknown at this time how many customers may be out of water. 

Due to the size and location of the pipe, some customers may experience discolored water. Customers are encouraged to run water until it clears. 

Currently, there is no estimate as to how long the repairs will take.

The Water Bureau's Maintenance & Construction crews are called out all hours day and night to repair broken water mains, an average of 200 times a year. In Portland, cast iron water mains tend to break during the colder times of the year. Cold water can cause pipes to become more brittle. Adding freezing temperatures such as what Portlanders have experienced in the past few days can cause the ground above a pipe to freeze, thereby increasing external stress on a pipe. Temperatures can be just one factor in causing a main break; the age of a pipe, soil conditions, pipe corrosion and ground movement can cause a main to weaken over time and break.
