Environmental Services has completed construction on a project to repair public sewer pipes in SW Yamhill and SW Morrison streets in downtown Portland. Repairs to the 100 to 140-year-old, deteriorating sewer pipes will protect the public and the environment by reducing the possibility of sewage releases to buildings and streets.
On Thursday night, November 14, crews completed the last remaining repair. This completes the planned repairs to public sewer mainline pipes and service laterals in this project.
The map below illustrates sewer pipe work locations in this project.
The entire SW Yamhill-Morrison Sewer Repair Project was a major construction project that was conducted in three phases and spanned three years of design and construction. Environmental Services knows it has meant significant inconvenience for downtown retailers, other businesses, and the many people living, working, and visiting in the project area. We appreciate your cooperation and patience as we worked through the unique technical challenges of the downtown environment (both above and below ground) to complete the necessary public sewer repairs. Thank you.
Environmental Services expresses special appreciation to the dozens of property owners, property managers, facility managers, and business owners and operators who collaborated with us to enable the necessary building site investigations, plumbing inspections, plumbing modifications, and actual construction to complete the sewer repair work. Thank you.
The Downtown-Old Town Sewer Repair Program, managed by the Bureau of Environmental Services, is a multi-year and multi-million-dollar investment to assess the condition of the aging public sewer system serving Portland's Downtown and Old Town neighborhoods and to upgrade it appropriately. Repairs now will extend the service life of public sewer pipes, increase their resiliency to earthquake damage, and help prevent sewage releases into downtown buildings and streets.
