Water Treatment Plant Construction Update

Form work and concrete pouring is continuing on-site for the clearwell, ballasted flocculation, gravity thickener, chemical building, mechanical dewatering and electrical building. Refer to the current site plan for locations of each structure.

Next Wednesday, May 14, the plant will be temporarily shut down to allow the contractor to cut into existing piping and install new fittings and valves near the mechanical building, on the northeast of the site. Neighbors can expect a new noise during the pipe cutting, which will occur in the morning hours. The work is expected to take one day to complete.

Over the next three Saturdays, firefighters from Clackamas Fire District #1, Tualatin Valley Fire & Rescue and the Lake Oswego Fire Department will be conducting training at the construction site with the contractor, Slayden. Neighbors may notice cranes lifting equipment, rope rescues from the tower crane, firefighters on-site, fire trucks and rigs arriving and leaving. Training will occur between 9 a.m. and 4 p.m. on May 10, 17 and 24. There may be some intermittent noise from back-up alarms when the rigs arrive to the site and idling of trucks, but this will be minimal. No sirens, jackhammers or invasive equipment will be used during the training.

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.

The walls in the clearwell are now complete! Work continues on installing shoring towers to support the formwork for the roof of the clearwell, in preparation for a concrete pour in the next few weeks and waterproofing the north walls of the clearwell.

Auger cast piles are also complete for the chemical building and electrical building foundations. No new auger cast piles will be drilled for the next few weeks, but the drill rig will remain on site.

Backfilling for the clearwell access ramp on the south side, near Mapleton Drive was completed last week. Form work and concrete pouring is the focus on-site over the next few weeks, for the clearwell, ballasted flocculation, gravity thickener, chemical building, mechanical dewatering and electrical building.

Water Treatment Plant Construction Update

The auger cast drill rig is continuing to drill piles for all new structures on site, including the mechanical dewatering building and electrical building - over half of the 1,100 auger cast piles have been installed to date!

Last week, work started on backfilling the access ramps into the south side of the clearwell near Mapleton Drive. The backfilling activity requires loaders to pick up and place gravel and rock, and then use a rolling vibratory compactor to compress the fill and gravel. The compaction in this area, and the northeast of the site close to the demolished lagoons will continue intermittently over the next few weeks. Form work and concrete pouring will also continue on-site over the next few weeks, for the clearwell and ballasted flocculation columns, walls and suspended roof.

Neighbors can expect some noise and potential vibration during the fill placement and compaction, auger cast drilling and concrete sandblasting, depending on locations or personal sensitivities. Truck traffic will continue during concrete and grout pouring for the auger cast piles and new foundations.

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. There will be no work on Saturday, April 26.

For more detail about what activities are happening on site please see the table below.

We apologize for the inconvenience construction may cause and thank you for your patience as work progresses.

For more information, please contact us or call the hotline at 503-697-6502.

Night Work in Lake Oswego

Starting next week and off and on through May, a crew will be working along the proposed water pipeline route that runs along portions of McVey Avenue (from State Street to the Lake Corp. Dam), State Street (B Avenue to the railroad tracks) and through the Oswego Village Shopping Center (Albertsons). They will be digging small holes in the right of way (or parking lot) to locate utilities in the area and testing soils.  This is to ensure that the proposed route has no conflicts with existing utilities and is designed with adequate support.

Work will occur during nighttime hours between 8:00 p.m. – 5:00 a.m. There will be a single-lane closure along roads to accommodate equipment, but no total street closure. The road will be repaired as work progresses. Please watch for flaggers. Neighbors may hear noise from a drill rig or a vacuum truck during these operations. We apologize for any inconvenience this may cause and appreciate your understanding during this important pre-construction work.

To see a map of anticipated work, visit the All Work Underway page.
