West Linn Pipeline Construction Update: Horizontal Directional Drilling site (end of Mapleton Dr.)
A milestone was reached last week, with the successful completion of the pilot hole! Drilling has been ongoing for a few weeks from either side of the river, with both drills meeting in the middle to complete the pilot hole.
Crews have now started the process of upsizing the hole to 36”. More passes will be made with larger drill bits (or reamers) over the next few months until the hole is large enough for the pipe to be pulled through.
During drilling work, 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. No work will occur over the Labor Day weekend, from Saturday, August 30 – Monday, September 1.
