Waterline replacement project on Harrison Street to impact traffic and water service

Mon Oct 31st, 2011

The City of Milwaukie City began a waterline replacement project from Campbell Street, just west of the railroad crossing, to 42nd Avenue on Oct. 31, 2011.

This project will replace old cast iron line with joints made of lead with new line made of ductile iron and rubber gasket joints.
The line is being replaced not due to the lead, which never is in contact with the flow of water, but because the old line is susceptible to cracking and leaking, the new line is made of much more long-lasting material, and because the City wants to get in the roadway and replace the infrastructure before scheduled work at the railroad crossing and the upcoming complete reconstruction of Harrison Street.

Additionally, this project will replace old service lines that may be leaking with new service pipe to each property, will add two new hydrants, and will install a considerable number of new valves that will improve City crew’s ability to localize shut off areas.

This waterline work represents the first stage in a three stage process that will dramatically improve Harrison Street from Campbell Street to 42nd Avenue. Work to install the required safety measures at the Harrison Street rail crossing that’s needed for the Quiet Zone implementation will be performed early Spring 2012, followed by the complete reconstruction of the roadway, set for late spring 2012. The waterline project is expected to be completed in December 2011.

During the waterline project nearby water customers will experience some intermittent interruptions in their water service. City water crews will distribute door hangers to affected customers two days prior to the expected interruptions.

Service will be interrupted when the contractor needs to connect the new main to the old main, which generally occurs at street intersections, and when new service lines are extended form the new main to the customer’s property line.

Work will take place in one area at a time and will be confined to less than one block. Two lanes of traffic will be maintained throughout the project, and all traffic lanes will be restored when work is concluded at the end of the day.
