SW Hamilton Terrace Sewer Repair Project

Updated July 23, 2019

Environmental Services is constructing a project on SW Hamilton Terrace to repair 200 linear feet of sewer line and a manhole that is deteriorating due to age. The sewer repair will extend the life of the sewer and protect public health, water quality, and the environment. 

Location

The manhole and pipe repair begin at the northern end of SW Hamilton Terrace, between SW Bancroft Street and SW Terwilliger Boulevard.

Traffic Impacts

SW Hamilton Terrace is closed to all traffic between SW Bancroft and SW Terwilliger from 9:00 am to 4:00 pm, Monday through Friday. This work is anticipated to be completed by the week of August 5.

Method of Construction

A trenchless method called Pipe Bursting has been used for this project. It involves digging an access pit and inserting a bursting head into the existing sewer line. The bursting head breaks the old pipe apart and pulls the new pipe into place behind it. This method was specifically selected to avoid removal of several 36-inch diameter fir trees.

For more information about pipe bursting, check out www.portlandoregon.gov/bes/pipebursting.
