Crews are moving through the project area repairing pubic sewers in the alleys through Cured-in-Place Pipe-Lining Map of upcoming construction(CIPP).

  • The pipe lining operation requires considerably less excavation than conventional pipe replacement.
  • If you live near CIPP work, you may smell a chemical-like odor during installation. This smell will dissipate quickly once the operation is complete. To avoid this odor, pour one gallon of water down all floor drains or any rarely used sinks/tubs/toilets to ensure that a water barrier is maintained in the traps.
  • To view photos and learn more about the CIPP construction method go to

Cleanout installations followed by concrete restoration will continue in multiple locations.

  • An average of six cleanouts will be installed in each alley where the mainline is being repaired.
  • Cleanout locations depend on the condition of service laterals that connect homes to the public sewer.


The map to the right shows the anticipated construction locations through September 1. Please be aware that construction schedules are subject to change due to underground conditions, weather, traffic impacts, subcontractor schedules and availability of materials.

Residents and businesses should expect periods of inactivity between each phase ranging from a few days to a few weeks. The duration depends on a variety of variables including underground conditions, weather, traffic impacts, subcontractor schedules, quality control tests and availability of materials. To learn more about visit the What to Expect During Construction page.

Construction Hours

Construction hours are from 7:00 a.m. to 6:00 p.m. Monday through Friday, but the contractor may schedule work during the same hours on Saturdays. The Portland Noise Office approved night work for two locations within the project boundaries. (This work is not in the current schedule.) Homes and businesses near these locations will receive a separate notification before night work takes place. Check the project map for night work

Let Us Know

Do you have problems with water seeping into your basement? Please let Environmental Services know by taking the online basement moisture survey. Survey responses help identify neighborhoods with seepage problems and design stormwater management projects.
