Sellwood-Moreland Sewer Repair Project

Sellwood-Moreland Sewer Repair Project Construction Update: May 27, 2015   

Environmental Services is repairing or replacing about 25,000 feet of public sewer pipes in the Sellwood-Moreland neighborhood that are between 80 and 100 years old and failing due to age. This project will help protect the public and the environment by reducing the possibility of costly breaks, leaks, blockages and sewage releases to homes, businesses and streets.

DEVELOPMENTS OF NOTE

  • Crews plan to work on Friday this week, due to the holiday on Monday. For most of the work, their schedule is generally Monday through Thursday.
  • Preparation for repairs will start on SE 17th Ave between Knapp and Rex. Crews will be finishing work between Bybee and Knapp late this week or early next week. Traffic on Milwaukie will continue to be slower than usual through June due to the detour for this work.
  • Cured-in-place-pipe (CIPP) repair has begun in the neighborhood. For the next several weeks, crews will continue to install flexible liners in pipes. Hot water or steam are circulated through the pipe to harden the liner and give the pipe a new interior surface. You may notice a chemical odor during pipe-lining. The odor is from styrene in the liner. Small amounts of airborne styrene produced are harmless and odor dissipates quickly.

CONSTRUCTION SCHEDULE
The anticipated construction schedule for the next three weeks is subject to change due to underground conditions, weather, subcontractor schedules and availability of materials. Specifically, street paving is conditional upon appropriate weather conditions.

WHAT TO EXPECT DURING CONSTRUCTION

  • Work hours are 7:00 a.m. to 6:00 p.m. Monday through Thursdays. The contractor may also work the same hours on Fridays and Saturdays.
  • A city inspector is on-site during work hours and may be able to assist you with construction concerns. Inspectors typically wear a City of Portland safety vest and hard hat.
  • As the contractor completes construction on each street, work crews apply a temporary patch. They will return later for permanent paving.
