About this file
This document is a horizontal directional drilling (HDD) plan and profile sheet for the Navajo-Gallup Water Supply Project, specifically the San Juan Lateral - Block 2 - 3 project in New Mexico. The plan details the Nenahnezad Bluff HDD drilling location, with precise geographic coordinates and elevation data for multiple waterline installations, including an NTUA 18" Ø Waterline and an APS 36" Ø Waterline. The drilling plan includes technical specifications such as drill hole location (R2-22-18), pipe top elevations ranging from approximately 5321.2 to 5344.1, and specific geographic positioning data. The document is prepared by the U.S. Bureau of Reclamation, with design and technical approvals from multiple engineers and a supervisory geologist, and includes critical notes about construction equipment restrictions and post-installation requirements.
