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.)

Drilling has been on hold this week while crews wait for a different steering tool to arrive

The pipe casing installation is now complete! Crews installed 60-inch diameter steel casing to about 160 feet. Thank you to neighbors for your patience during this noisy activity.

Drilling of the first pilot hole under the river began last week. The hole is being drilled through rock and is currently installed to about 1,000 feet. To learn more, read Water Savvy #9, Horizontal Directional Drilling (pdf 823 kb).

This week has been a quiet one at the site, as drilling has been on hold. Crews are waiting for a different steering tool (gyroscope) to arrive in the next week. Once the gyroscope is installed, drilling will resume at the site.

During drilling, neighbors may hear noise from the drill rig and an increase in truck traffic. Work hours are 7 a.m. - 7 p.m., Monday through Friday, and Saturdays from 9 a.m. - 5 p.m.

Water Treatment Plant Construction Update

The thickener equipment for the gravity thickener tank arrived from Salt Lake City this week
