Bonita Pump Station Construction Update

Preparing the site to grade for the generator pad

Concrete is poured for the meter vault walls

This week, crews poured concrete for the meter vault walls and began excavating for the pump can (enclosure for the pump). Soil was also removed out of the vegetated corridor to prepare for plantings in the next few months. The site for the generator pad was also graded, to prepare for a concrete pour.

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.
