North Powder-Rock Creek Pipeline

The North Powder–Rock Creek Pipeline project is located approximately 12 miles northwest of Baker City, Oregon. The project replaced over seven miles of corroded steel pipeline with polyvinyl chloride plastic pipe. The pipeline serves 17 irrigation turnouts with a design capacity of over 24 cubic feet per second. The largest pipe diameter is 27 inches.
Unique features of the design include the following:

  • Supplied water to the pipeline through two inlet structures located two miles apart on separate creeks.

  • Performed a detailed surge analysis for cost effective pipe sizing.

  • Buried one mile of large diameter pipeline five feet below the center of a winding mountain road.

  • Regulated multiple inlet flows with an inline throttle valve.

  • Regulated system pressure with high capacity, multiple valve pressure reducing stations.

  • Installed numerous vacuum relief, air release, and pressure relief valves to protect the pipeline.

  • Installed both electromagnetic and mechanical flow meters throughout the system for water management.

The project was designed in early 1999. Construction began in the fall of 1999 and was completed in the spring of 2000 at a cost of approximately $2,000,000.
