What’s Happening Now

Thursday, September 2, and Friday, September 3, crews are scheduled to repair the remaining section of sewer pipe using a trenchless method called cured-in-place-pipe lining (CIPP). The week of September 6, paving crews will restore areas of the street disturbed by construction. You may also see other pre-construction activities described on our website www.portlandoregon.gov/bes/precon.

We Want to Hear from You

Please contact us if you have any concerns related to business operations, disability or mobility issues, and medical or business deliveries.  Your input will help us design a successful sewer project that minimizes the impact to your neighborhood during construction.

Construction Methods 

The contractor will use  two construction methods to complete sewer and stormwater improvements. Some will require digging trenches. Others will replace pipes through manholes or access pits to reduce surface disruption. 

  • Open Trench Excavation: The contractor excavates a trench, installs a new pipe, fills in the trench and restores the disturbed pavement. 

  • Cured-in-Place-Pipe Lining (CIPP): Through a manhole, the contractor inserts a flexible liner into the old pipe. The liner hardens, creating a new interior lining. You may smell an odor like plastic or glue during this process from the liner resin. 

Night Work

Most work will be completed during regular work hours from 7 a.m. to 6 p.m., Monday through Friday, and Saturdays as needed. However, crews will need to work up to five (5) nights in order to complete main sewer pipe repairs using Cured-in-Place Pipe-Lining (CIPP). Due to the large size of the pipe being repaired near you, it will take about 16 hours or more to complete the CIPP process, allow the liner to fully cure, and to clean up. This will require working from morning into the evening and possibly overnight during each shift where CIPP is being used.  

What to Expect

You can expect the following activities and impacts during construction: 

A Safe Work Site: We want you to be safe around the work site. Please keep children, pets, bikes, cars, and trucks away from the tools, machines, supplies, and construction workers. 

Noise, Vibration, and Dust: Construction creates noise, vibration, and dust and disrupts normal neighborhood activity. 

Traffic Delays: The work will slow down traffic in your neighborhood. Please read the traffic signs and follow directions from the workers with flags. 

Access to Your Home or Business: You will be able to go to your home or business, but you may not be able to park as close as you would like. We will try to make sure driveways and parking lot entrances stay open. Crew members can help you safely enter or exit your driveway or business parking lot.   

Parking Restrictions: We want you to be safe, so you might not be able to park your car next to work spaces, equipment, or materials. If crews are working directly in front of your home or a business, you may need to park in another place. 

Equipment Storage: Sometimes we will leave tools, machines, and supplies on your street overnight.  

Maintained Service: You can still use sewer, water, and other services while we work on your street. 

Schedule Changes and Inactivity: Work schedules can change for many reasons like weather, traffic, and problems with tools, machines, or supplies. Sometimes we need to stop between different types of work and start again later. 

Day and Night Work: Most work will be completed during regular work hours from 7 a.m. to 6 p.m., Monday through Friday, and Saturdays as needed. However, crews will need to work up to five (5) night shifts in order to complete main sewer pipe repairs using Cured-in-Place Pipe-Lining (CIPP).
