Dog River Pipeline Replacement Design Complete, Getting Ready for Construction

Dog River Pipeline Head GateThe City recently achieved a big milestone and completed design for the Dog River Pipeline Replacement project. The Dog River is an essential source of drinking water that provides more than half of the City’s annual water supply. With the new pipeline, the City is taking strides to improve reliability and resilience of the water system by replacing a 3.5-mile aging wooden pipeline in Mt. Hood National Forest.

Now that pipeline design is wrapped up, the City is working with key project partners at the Forest Service and gearing up for two seasons of construction. In the next few months, the pipeline corridor will be cleared of trees and brush to prepare for summer construction activities. The work is planned over two seasons to allow for mountain weather.

To keep customers and recreation users up to date on the latest, the City created a project webpage with background materials and upcoming milestones. For more project information and to sign up to receive project announcements visit
