Sheridan Trunk Sewer Project – Water to Moody

Sewer and Stormwater
Active
Environmental Services has started a project to repair 524 feet of public sewer pipe on SW Sheridan Street between Water and Moody avenues. Having provided over 135 years of service, the pipes require repairs to maintain reliable sewer service and protect public health and the environment.
Construction started in mid-January 2025 and will take up to six months to complete.

Project Area 

The project will occur on Southwest Sheridan Street between Southwest Water and Moody avenues and a small area in the OHSU parking lot just east of Moody.   

Schedule

Construction started in mid-January 2025 and will take up to six months to complete.

This work is highly weather dependent, and crews may stop work during periods of wet weather and start again when forecasts call for drier weather. Periods of inactivity may range from a few days to a few weeks. We will be monitoring the rain levels daily and will work to complete the project as the weather allows. 

What's Happening Now

Throughout February and March 2025, weather permitting, crews will be in the area during normal construction hours (Monday through Friday, 7 a.m. to 6 p.m.) to grout and finalize construction.  To complete the project during the seasonal wet and cooler weather, crews may work on Saturdays between 7 a.m. to 6 p.m. during drier and warmer weather. All work is weather-dependent, and the schedule below is subject to change.

Week of February 10

  • Due to the severe weather affecting the Portland Metro area, crews will not be in the area and work will be paused until conditions improve.

Week of February 17

  • Crews will access the project area through existing manholes utilizing a Spiral Wound Pipe Lining process to install the liner within the trunk, and complete additional supporting construction activities.  You can expect to see construction trucks and equipment in the area and hear normal construction noises. 

Week of February 24

  • Crews will begin building bulkheads and complete additional construction activities.  You will continue to see construction trucks and equipment in the area and hear normal construction noises. 

What to Expect During Construction

Construction hours are Monday through Friday from 7 a.m. to 6 p.m. Crews may work on some Saturdays as well. The City will allow night and weekend work to finish construction during dry weather.  During construction, crews will need to access the sewer mainline from the corner of the OHSU Schnitzer Parking Lot. 

You can expect the following activities to occur during construction hours:

  • Noise, vibration, and dust
  • Traffic delays
  • Parking restrictions
  • Equipment storage overnight
  • Continued sewer service during work hours
  • Maintained access to your home or business

A brief guide on what you can expect during construction projects conducted by Environmental Services and their contractors can be found at portland.gov/bes/constructionimpacts.

Night and Weekend Work

In order to continue to convey flows during construction, Environmental Services may need to operate bypass pumping equipment overnight and on weekends in 2024 in Southwest Sheridan Street between Southwest Water and Moody avenues, and a small area in the OHSU parking lot just east of Moody. This may take place for up to 10 nights. 

Environmental Services has been granted a noise variance to work at night. A noise variance is required when work occurs outside normal construction hours of 7 a.m. to 6 p.m. Monday through Saturday.

Construction Methods

The City’s contractor may use several construction methods to repair the sewer pipe. Some areas may require digging access pits to install the pipe.  

Construction methods may include the following:  

  • Spiral Wound Pipe Lining is a trenchless method. It requires little or no digging and can be installed when sewage and stormwater are flowing through the pipe.
  • Open Trench Excavation to dig small trenches to replace short sections of broken pipe before repairing the entire mainline sewer pipe, and to construct sewer service laterals and access pits.
