Northwest Pipe Company (NWPX), the engineered welded steel pipe products for the water transmission market, was selected by Oscar Renda Contracting to supply pipe for Reach 4C through Reach 8 of the Navajo-Gallup Water Supply Project.
The Navajo-Gallup Water Supply Project is a multi-phased major infrastructure project underway in northwest New Mexico. The U.S. Bureau of Reclamation in conjunction with the Navajo Nation is constructing the project. Once complete, the project will convey reliable municipal and industrial water supply from the San Juan River to the eastern section of the Navajo Nation, the southwestern portion of the Jicarilla Apache Nation, and the City of Gallup. At build-out, the project will encompass 280 miles of pipeline, several pumping plants, and two water treatment plants.
These areas currently rely on a rapidly depleting groundwater supply. Groundwater levels for the City of Gallup have dropped approximately 200 feet over the past 10 years and over 40% of Navajo Nation households haul water to meet their daily needs. This project will provide a long-term sustainable water supply for approximately 250,000 people by the year 2040 with an annual delivery of over 37,700 acre-feet of water from the San Juan Basin.
Reach 4C through Reach 8 covers over 28 miles and runs through San Juan and McKinley Counties in New Mexico. Engineered water pipe for these sections consists of a 42-inch and 48-inch spiral-welded steel pipe with cement mortar-lining and polyurethane coating. The Company will manufacture over 7,300 tons of pipe for this project.
