Environmental Services is planning a project to repair or replace about 7,000 feet of deteriorating sewer pipes in the Kenton neighborhood. The project will extend the life of the public sewer and help avoid costly breaks, leaks and blockages in the future. Construction is scheduled to begin in 2014 and will take a year to complete. The city’s contractor will use a combination of open trench construction and trenchless construction techniques. This project will also correct nonconforming sewer connections at some properties.
The map below shows the location of pipes Environmental Services will repair or replace in 2014. There will be construction only on the streets indicated on the map. There may be traffic control, construction signs or increased traffic volume on nearby streets.
In September 2013, work crews will conduct geotechnical investigations to help design engineers understand conditions underground that construction crews may encounter when the project begins. What the engineers learn from soil and rock samples will help them determine construction methods. To obtain soil samples, crews will bore holes in street pavement at several locations (see map above).
What to Expect During Soil Sampling
- Soil sampling will occur Monday through Friday, between 7:00 a.m. and 6:00 p.m.
- Crews will work at two or three locations a day.
- The holes will be relatively small in diameter and shallow and will be filled immediately after the drillings are completed.
- Lane restrictions and parking removal may be necessary during drilling.
- The work may create brief periods of noise and dust.
Over one-third of Portland’s 2,500 miles of sewer pipes are more than 80 years old. Projects to replace or repair aging sewers are important for protecting water quality, public health, and the environment.
