SE 45th/46th and Sherman Sewer Repair Project

Environmental Services is designing a project to replace and upsize about 700 feet of public sewer pipes on SE 45th and SE 46th avenues between SE Sherman and SE Division streets that are 103 years old and deteriorating due to age. Several pipes have holes and roots in them.

Since the last update, engineers altered the project design to add a 320-foot pipe segment on SE Ivon Street between SE 41st and SE 42nd avenues.

This project will improve the public sewer system and reduce the risks of street flooding and sewage releases to homes and streets.

The work will include repairing or replacing 11 storm drains, 3 manholes, and 35 service laterals that connect houses from the curb to the public sewer in the street. In addition, this project will work with individual property owners on SE 45th and SE 46th avenues with nonconforming sewer connections to resolve issues and provide those properties direct connections to the public sewer system.
