All Work Underway
|Work underway||Road closure||Partial closure||Night Work|
Most pipeline for the project is installed in the public right of way. There is an exception, where the pipeline tunnels under the Willamette River. Read the What to Expect During Construction handout (781 kb, May 2014) for more detailed maps and information about the construction process.
Ballasted flocculation – center of site
Large mechanical equipment deliveries are continuing to arrive and be installed for the ballasted flocculation. Over the next two weeks, water testing of two tanks in the south of the structure will begin.
Temporary storage building – southeast of site
Work continues on installing a temporary storage building on the southeast corner of the site (photo shown on the left). It will store large equipment arriving on site, to be installed later. The building will be removed near the end of the project.
Chemical & electrical buildings – center of site
Crews are forming and pouring the truck loading slabs for the chemical building. Starting next week, concrete blocks for the walls will be placed. Over the next two weeks, structural steel will be placed for the electrical building.
Finished Water Pump Station and Clearwell – south and center of site
Wall pours are now complete for the finished water pump station. Crews are installing piping support and next week, the exterior coating will be applied. Once this is complete, the area will be backfilled. During backfilling, neighbors close to the center of the site may experience an increase in vibration, as the compactor compresses fill. Over the next few weeks, crews will begin cleaning the clearwell tank and filling it for the water test.
Installation of the 30” – 48” piping across the site continues, including excavating, placing the pipe, encasing it in concrete and backfilling the trench. During the excavating and backfilling, neighbors may experience an increase in truck traffic, noise and vibration.
Work hours are Monday to Friday from 7:00 a.m. to 7:00 p.m. and Saturdays, from 9:00 a.m. to 5:00 p.m. Please refer to the current site plan for locations of each structure.
WTP construction tours – next tour is October 16
Due to scheduling and holiday conflicts, October and December tours will be held on the third Thursday of the month at 10 a.m. (October 16 and December 18). Advance registration is required and space is limited. Please contact us to sign up for a tour!
Neighborhood construction meetings – first and third Tuesday of the month
The next meeting will be held on October 7, at 7:30 a.m. in the downstairs restaurant area at Burgerville, 18350 Willamette Drive, West Linn. Please come along to stay updated on construction progress in West Linn and ask questions of the project team. All meeting materials are posted online under “past meetings and events.”

Crushed rock ready to re-use as fill
In recent weeks, in a sustainable effort to reuse natural resources, crews crushed rock that had previously been excavated from the WR2 site. The crushed rock is now ready to re-use as fill material on site. No rock-crushing is anticipated for at least the next couple of weeks.
WR2 wall construction more than 50% complete
Crews will pour the 6th reservoir wall today. Each wall pour takes approximately 6 hours. The walls are being poured with concrete every other day. The 7th reservoir wall is expected to be poured on Monday, 9/29. The final wall pour will take place during the week beginning 10/6.
During the wall pours, neighbors can expect to see about 5 concrete trucks traveling to and from the site and hear noise from a concrete pump truck, from 7:00 a.m. Flaggers will guide trucks in and out of the site, so please approach the Carman Drive curves cautiously.
Preparing for WR2 roof shore
Tomorrow, rebar that will be used to support the WR2 roof will be delivered. Once the reservoir walls are complete, crews will begin work on the roof support. This work is expected to take approximately 15 working days.
Construction work hours
Construction work hours are 7 a.m. to 6 p.m., Monday to Friday. No work will take place this Saturday.
On Saturday, 10/4, for a half-day only (from 8 a.m.-12 p.m.), a small crew will be pulling out ‘taper ties’ (that hold wall forms together). Neighbors can expect a modest level of intermittent banging noise during this time. There will no construction equipment operating.
