  • The Navajo-Gallup Water Supply Project will provide a reliable long-term municipal and industrial water supply to the eastern section of the Navajo Nation, southwestern portion of the Jicarilla Apache Nation, and the city of Gallup, New Mexico.
  • These areas currently rely on rapidly depleting groundwater of poor quality and inadequate to meet current and future demands of more than 43 Navajo chapters including fort Defiance and Window Rock in Arizona, the city of Gallup, New Mexico, and the Teepee Junction area of the Jicarilla Apache Nation.
  • The project will divert 37,376 acre-feet of water annually from the San Juan River Basin and convey it via approximately 280 miles of pipeline, several pumping plants, and two water treatment plants.
  • This water supply will support a future population of approximately 250,000 people by the year 2040.
  • The project was authorized for construction by the Omnibus Public Lands Management Act of 2009 (P.L. 111-11) on March 30, 2009 as a major component of the Navajo Nation San Juan River Basin Water Rights Settlement in New Mexico.
  • The legislation requires the completion of all project feature construction no later than December 31, 2024.
  • Based on October 2011 prices, the total indexed construction cost estimate for the project is approximately $995,000,000. P.L. allows for future indexing of costs based upon engineering indices.
  • The Claims Resolution Act (P. L. 111-291) provides access to up to $60 million in mandatory funding for the project in each of fiscal years 2012, 2013, and 2014. The mandatory funding is designated for several water rights settlements of which NGWSP is the first priority (in accordance with P.L. 111-11). In addition, $24.8 million was requested in the President’s fiscal year 2012 request.
  • The start of project construction is dependent on completion of various permitting, land acquisition, and contract activities and is scheduled to begin in 2012.
  • As one of the 14 infrastructure projects identified by the Obama Administration to be expedited through the permitting and environmental review process, Reclamation is working with federal, non-federal, and Tribal entities to facilitate construction activities as soon as possible.
  • Once project construction begins, it is anticipated that between 400-450 jobs will be created. As the project reaches the peak of construction activities, it is anticipated that a total of 600-650 jobs will have been created.
  • The overall project schedule is determined by the Project Construction Committee consisting of representatives from Reclamation, city of Gallup, Navajo Nation, Jicarilla Apache Nation, and state of New Mexico. The project schedule is driven by funding provided through Congress and state of New Mexico.
  • In addition to Reclamation, the city of Gallup, Navajo Nation, and Indian Health Service will simultaneously perform design and construction tasks for various project reaches under their own authorities in accordance with financial assistance agreements with Reclamation.
