The City of Portland’s Bureau of Environmental Services is continuing our work to repair and replace critical sewer and stormwater infrastructure. Environmental Services will continue to provide information and updates on construction schedules and activities during the COVID-19 emergency.
Updated August 11, 2020
Environmental Services continues a project to repair about 160 feet of large public sewer pipe in NE 29th Ave between NE Sandy Boulevard and Sullivan Street. This section of sewer pipe is showing signs of deterioration due to age.
Please keep in mind that schedules may change due to a variety of factors such as weather and subcontractor availability.
Crews have completed the majority of open trench excavation to install a large manhole at the intersection of NE 29th Avenue and Sullivan Street. A steel plate will remain over the excavation until Phase 2 is complete. Go to www.portlandoregon.gov/bes/opentrench to learn more about open trench excavation.
Work to repair a larger diameter sewer pipe under NE 29th Avenue between Sullivan Street and Sandy Boulevard using CIPP is on hold until materials on order for this phase arrive. This work was originally expected to occur in August, but now is expected to occur in September. Go to www.portlandoregon.gov/bes/pipelining to learn more about CIPP.
Local traffic on Sullivan Street will be maintained, but the intersection of NE 29th and Sullivan will be hard closed during installation of the manhole during Phase 1. Cars using Sullivan Street for parking or deliveries should be prepared to enter and exit from 30th Avenue and Sandy Boulevard.
This project will include both trenchless and trench excavation construction methods:

You can expect the following activities and impacts during construction:
Most work will be completed during regular work hours from 7 a.m. to 6 p.m. Monday through Friday, and Saturdays if needed. However, crews will need to work one night shift in order to complete mainline sewer pipe repairs using CIPP, which requires inserting a flexible liner inside the old pipe, inflating the liner, and exposing it to heat or ultraviolet light (UV) to “cure” the pipe.
Due to the large diameter 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. You will be notified if additional night shifts are needed.
Environmental Services is working directly with adjacent properties affected by this project. Community outreach staff will listen to your suggestions and respond to your concerns:
We encourage you to support local businesses during this difficult time. You can still shop online for goods and gift certificates, and many stores and restaurants are open and accessible for pickup or delivery of food and drink.
