SE 26th Avenue and Gladstone Sewer Repair Project

Sewer and Stormwater
Environmental Services completed a project to replace an existing 114-year‐old, 240-foot-long public sewer pipe in the Creston-Kenilworth neighborhood. This project will protect public health and the environment by increasing the capacity of the public sewer system.
Construction began in February 2024 and took three months to complete.

We Want to Thank You

We recognize wholeheartedly that sewer construction can be disruptive. We thank you for your patience, cooperation, and complete understanding during this important project.

Environmental Services and our contractors work throughout Portland neighborhoods to repair and replace critical sections of deteriorating sewer pipes. These timely repairs protect public health and the environment by reducing the risk of sewage releases to buildings, streets, greenspaces, rivers, and streams.  

Project Goals

The new mainline sewer system will provide properties with aging septic systems, a direct way to connect to the public sewer system. Projects often require a combination of trenchless and open trench construction to repair and replace sewer pipes. The project used open trench excavation, cured-in-place-pipe lining (CIPP), and pipe reaming construction methods to repair severely cracked piping and expand the sewer system’s capacity. 

Completed construction work includes the following:

  • Replacement of corroded 10-inch pipe with new and sustainable 12-inch PVC (polyvinyl chloride) piping.
  • Improvements to sewer lateral connections for up to ten private properties and several local businesses.
  • Tree maintenance including tree trimming and protectionnuisance removal, as well as replanting.
  • Permanent trench paving restoration on SE 26th Avenue, within right of way (ROW).

Environmental Services will own and maintain the new sewer main in the street. Additionally, crews will repair or replace sidewalks, driveway aprons, and curbs as needed. The city will also replace topsoil and grass seed in planting strips, and any street trees that were removed.
