Judy Reservoir to Mount Vernon Pipeline Project Underway

Posted Thursday, August 19, 2021

Construction is underway for Phase II of the Judy Reservoir to Mount Vernon Transmission Pipeline Project. The estimated cost for the two-year project is $35.6 million. Phase II will be installed within the right-of-way and private property in Mount Vernon and unincorporated Skagit County.

Installation includes 5.3 miles of 36-inch diameter welded steel transmission pipeline. Part of the project requires drilling under the Nookachamps Creek.

In 2010, Phase I of the Judy Reservoir to Mount Vernon Transmission Pipeline project was completed for $4.2 million. Phase I ran 1.6 miles and followed the Kulshan Avenue right-of-way in Mount Vernon.

Why do the project now?

The original 24-inch diameter concrete cylinder pipe was installed in the early 1960s. Large sections of the existing transmission line are virtually inaccessible most of the year because of surface and groundwater conditions. Recently, several significant line breaks have confirmed that the pipe’s useful life is ending.

Phase II is partially funded through the Washington State Public Works Board program and the Washington State Drinking Water State Revolving Fund Program, with federal funds coming from the U.S. Environmental Protection Agency.
