What is this Project?

This project increases system capacity to deliver high-quality drinking water from the Clackamas River to the communities of Lake Oswego and Tigard. Together these two communities can secure long-term access to clean, safe water for less than it would cost them to do it alone. Learn more...

West Linn Pipeline Construction Update: Horizontal Directional Drilling site (end of Mapleton Dr.)

Pipe casing installation progressing well

The pipe casing work started last week and is progressing well at the HDD site, just north of Mary S. Young Park. The 60-inch steel casing has been installed to about 160 feet, and is almost complete. Thank you to neighbors for your patience during this noisy activity. Crews are now determining if they have reached stable, solid ground (bedrock) before drilling the pilot hole under the river. Additional casing lengths may need to be installed using the pressurized hammer, depending on ground conditions.

Water Treatment Plant Construction Update

Rebar cages for 48” overflow auger cast piles arrived at the site this week

This week, crews starting excavating and installing the slide rail shoring system for the new 48” overflow pipe near the chemical building. This is the same shoring system that was used on-site last month for the 54” pipe (not sheet piling that was used earlier this year). Auger cast pile drilling also resumed to support the new pipe, and will continue next week. Over the next few weeks, crews will lay the 48” overflow piping, weld it together and then encase it in concrete.

Bonita Pump Station Construction Update

Crews begin excavation for the meter vault

Last week, crews removed rock and debris from an old road bed within the vegetative corridor around the wetlands.

Over the next two weeks, soil testing will be completed to check for nutrients to see which soil amendments are needed for the corridor before planting occurs in October. The split rail fencing around a portion of the site (to match the fencing along a portion of the frontage in Bonita Park across the street) will also be installed. Irrigation for the vegetated corridor will also be put in place.
