As part of a large-scale update to the Lake Oswego and Tigard water systems, AAC worked with the Frank Coluccio Construction Company in the Fall of 2014 to install 3900 lineal feet of steel pipe pulled through a tunnel beneath the Willamette River. A continuous, around-the-clock operation methodically executed the pipe pullback process to place the underground water system.
This fast track project, in an urban setting with strict environmental restrictions was a key part of the broader Lake Oswego –Tigard Water Partnership to update an old system and establish secure, dependable drinking water for both Lake Oswego and Tigard. Once all phases of the project are complete, the pipeline will carry up to 38 million gallons of water a day.
