Portland's sewer collection and treatment system includes about 2,500 miles of sewer pipe. About one-third of those pipes are 80 years old or older.
Environmental Services construction projects around Portland are repairing or replacing critical sections of sewer pipe that are failing or at risk of failure.
For some projects, traditional open trench sewer construction is the only feasible option available. But when possible, Environmental Services uses trenchless sewer construction methods, or a combination of trenchless and open trench construction, to replace and repair sewers. Trenchless methods minimize disruption to sidewalks, curbs, streets, traffic, other utilities and neighborhood livability. Choose the links on this page to read more about pipe repair methods.
