Avista Utilities to replace Oregon natural gas pipeline as part of 20-year infrastructure program

(UI) – The Roseburg Public Works Department announced that natural gas pipeline replacements will resume on Stewart Parkway before continuing onto Garden Valley Boulevard.

Starting Monday, Feb. 19, Avista Utilities and its authorized contractor, Michels Corp., will be replacing aging natural gas mains in the public right-of-way, streets and alleys.

Construction is expected to be completed by Tuesday, April 30. The project will begin on NW Stewart Parkway at the entrance to Walmart and continue south on Stewart Parkway to NW Garden Valley Boulevard, then west on Garden Valley Boulevard to NW Newcastle Street.

The pipe replacement is part of Avista's 20-year natural gas replacement program that began in 2012. The program focuses on replacing Aldyl-A pipe that is 1.25 inches to 4 inches in diameter and was installed before Jan. 1, 1987, or manufactured before January 1985. Replacement is required for natural gas utilities across the country.

Avista replaces infrastructure when the materials exceed their useful life or to accommodate future growth due to additional energy demand. Avista is continually updating equipment and infrastructure to increase the safety and reliability of its system.
