Hillsdale Sewer Repair Project

Updated November 30, 2018Button. Click to sign up for email updates

Environmental Services is designing projects in the Hillsdale and Multnomah neighborhoods of Southwest Portland to repair or replace 30,000 feet, or 5.7 miles, of public sewer pipes that are on average 80 years old and in deteriorating condition. Project design is currently focused on 9,000 feet, or 1.7 miles, in the South section.

The project will also install new manholes and storm drain inlets where needed, repair existing manholes and storm drain inlets, and replace some public sewer connections to private properties from the main line in the street to the curb. This investment in your neighborhood will ensure continued dependable sewer service and protect the public and our environment by reducing the possibility of sewage releases to homes, businesses, and streets.

Engineers have determined which pipes will be repaired, and have also identified construction methods and potential night work locations. To learn more about these construction methods click here.

Project Area

The project design is currently focused on the South section, which will include about 9,000 feet, or 1.7 miles, of sewer pipes. Below is a map of the southern section of the project, and shows the construction methods and locations for potential night work.

Upcoming construction map

Schedule

Design in the South section will continue through 2018. A construction contractor will be selected in early 2019. Construction in the South section only is anticipated to begin in the fall of 2019 and take up to a year and a half to complete.

Design and construction timelines for the Middle and North sections are not yet known. They will be done sometime after the South section.

Design Update

Over the last few months, crews have been in the neighborhood surveying, locating utilities, inspecting sewer pipes and manholes, studying soil types and conditions, and collecting information to help engineers decide which locations need repair and what construction methods are best for each location. You may still see crews in the neighborhood conducting these activities.

These design and pre-construction activities typically occur over time, rather than all at once.

New Night Work Proposed

Our previous notice included proposed night work on Capitol Highway. The Portland Noise Office approved that work to be coordinated with the Portland Bureau of Transportation on their Capitol Highway repaving project.

Engineers have identified additional locations that will likely require night work (see the map above). Due to the length and diameter of a few pipes, and traffic safety reasons, some of the work will extend a few hours beyond 6:00 p.m. or will need to be done overnight. Equipment that generates noise will include sewer cleaning trucks, compressors, light trucks, generators, pumps, and ventilation fans. Night work will require lighting of the work zone.

Submit Comments to the Portland Noise Office

Work after 6:00 p.m. and before 7:00 a.m. and all hours on Sundays requires a noise variance from the Portland Noise Office. Environmental Services will apply for a noise variance to enable the city’s contractors to work both days and nights in certain locations.

Your comments regarding the proposed schedule to work both days and nights are valuable, and you can submit them to the Portland Noise Office by letter, or email.  Please submit comments by Friday, November 16 to:

Construction Methods

This project will include both trenchless and trench excavation methods:

  • Open Trench Pipe Repair: The contractor digs a trench, installs a new pipe, fills in the trench, and restores the street to its previous condition.
  • Pipe Lining (CIPP): Through a manhole, the contractor inserts a flexible liner into the existing pipe.  The liner hardens to seal cracks and form a new smooth pipe.
  • Pipe Bursting: The contractor pushes a bursting head into the sewer line to break apart the existing pipe while pulling a new pipe into place behind it.
