Sheridan Trunk Sewer Project – Water to Moody

Sewer and Stormwater
Active
Environmental Services is designing a project to repair 524 feet of public sewer pipe on Southwest 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.
Sewer repairs are anticipated to begin in May 2024 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.   

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. 

What's Happening Now

Over the next few months, crew will be in the project area conducting various investigations to collect information that will help determine what pipes need to be repaired and what construction methods should be used. Activities may include cleaning and inspecting sewer pipes and maintenance access holes, locating underground utilities and marking them with paint or small flags, surveying the land and taking various measurements, and drilling holes in the street to collect soil and pavement samples. See Pre-Construction Activities to learn more.  

Some investigative activities will require restricting parking and closing travel lanes. Information gathered will help determine the repair locations, construction methods, and how to minimize construction impacts on residents and businesses.  

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.
