About this file
This document is a set of engineering drawings for the Navajo-Gallup Water Supply Project, specifically focusing on the Horizontal Directional Drilling (HDD) at the Nenahnezad Bluff site in New Mexico. The project involves multiple waterline installations, including NTUA (Navajo Tribal Utility Authority) and APS waterlines, with a proposed HDD crossing at station 2832+94. The drawings detail the site plan, geological profile, contractor use areas, and pipe laydown areas for the San Juan Lateral - Block 2-3 segment.
Key technical details include a horizontal directional drill with a total length of 1324 LF (linear feet), multiple waterline installations with top of pipe elevations ranging from 5321.2 to 5344.1, and specific geographic coordinates for the HDD entry and exit points. The project involves complex terrain navigation, with careful consideration of existing geological formations (Qal, Kpc layers) and topographical challenges. The Bureau of Reclamation, U.S. Department of the Interior, is the lead agency, with design and technical approvals completed by engineers Andrew Marner, K. Pelzer, and Timothy Steen.
