Most pipeline for the project is installed in the public right of way. There are two exceptions, where the pipeline tunnels under the Willamette River and under Oswego Lake.

Exploratory Digging Work: Boones Ferry Road, Lanewood St, Douglas Circle, Twin Fir Road, Upper Drive, Iron Mountain Blvd. and Chandler Road
Beginning in mid December, crews will be working along the proposed water pipeline route that runs east from Lake Grove School and Boones Ferry Road along Lanewood Street, Douglas Circle, Twin Fir Road, Upper Drive, Iron Mountain Boulevard and Chandler Road. They will dig small holes in the roadway to locate all underground utilities and pipes, to ensure the pipeline route does not conflict with existing utilities.
Workers will use a vacuum truck and small excavator, digging holes 50 to 150 feet apart as they travel along the pipeline route. Holes will be repaired as work progresses. Work is expected to continue through the end of January 2014.
The following table outlines key locations and approximate timeframes for the digging work.
This week at the water treatment plant (WTP) construction site, work continued on installing a dewatering system to control ground water in the finished water pump station. A 100 ton mobile crane also arrived on-site, and excavation of a new clearwell access ramp for the auger cast crane was completed.
Next week will be a short week, with no work occurring on Thanksgiving Day, the Friday after Thanksgiving or Saturday November 30.
The Partnership has recently reformatted the construction updates to include more detail on construction activities, purpose and duration of work.
The table below describes what activities are happening on-site the next few weeks.
To support the future access bridge, all 27 piles have now been drilled and installed in the ground at the river intake pump station (RIPS) site.
Work is now continuing on the forms for the RIPS walls and placement of reinforced bar in the bottom of the cofferdam. A large concrete pour is scheduled to occur around the wall forms the week beginning December 2. This should take about one day. After the pour, the wall forms will be removed from the bottom layer and reinstalled above the concrete. This work will continue over the next month.
During the concrete pour, neighbors can expect some noise and an increase in truck traffic as 12-15 concrete trucks arrive at the site. Generally, during the next three weeks, work hours will be 7:00 a.m. to 6:00 p.m. Monday through Friday, with no Saturday work expected. No work will occur on Thanksgiving Day or the Friday after.
