Corrosion control project crews make the crucial connections 

Crews haven’t let Portland’s warm summer weather slow them down. They’re keeping up the pace and have made impressive progress, starting with the installation of the silos back in May. In August, they completed pipeline boring across SE Lusted Road and are now making the final connections for the improved corrosion control facility’s pipeline system. They anticipate this work, along with final grading, to be complete in September. 

Pipeline drilling on private property off Lusted Road; anticipate noise

Pipeline drilling begins off Lusted Road, east of Altman Road, and is expected to be completed Thursday, Sept. 2. This activity is on private property and not in the right-of-way or public roads. Work hours will be between 8 a.m. and 5 p.m. Anticipate noise, typically ranging from 70 to 80 decibels, comparable to a medium-sized tractor.

About the Bull Run Treatment Projects

To comply with federal Safe Drinking Water Act regulations, the Portland Water Bureau is building a water filtration facility, new pipelines, and an improved corrosion control treatment facility. The Bull Run Treatment Projects will provide consistent, high-quality drinking water that meets today’s water quality standards, help address aging infrastructure concerns and future risks and regulations, and improve system resilience to help keep our water safe and abundant for generations to come.
