About this file

Written by GovTribe AI · Aug 27, 2025

This file is a detailed technical drawing (00_00_02_Dwgs-B_001-100_22x34_04-20-2025_4.pdf) for the Navajo-Gallup Water Supply Project's San Juan Lateral - Reach 1 Intake and River Pumping Plant located near Farmington, New Mexico. The drawing set provides comprehensive site plans, excavation details, utility layouts, and grading specifications for a new water infrastructure project involving a river intake, pumping plant, and associated infrastructure.

Key technical elements include a cement-bentonite slurry cutoff wall, detailed excavation plans for various site features (intake channel, settling channel, outlet channel), a 42-inch pipeline connection, utility installations, gravel surfacing, and precise grading control points. The project involves multiple structures and infrastructure components across approximately 125 acres, with elevation changes ranging from 5075 to 5100 feet. The drawings are prepared by the Bureau of Reclamation and dated April 2025, indicating an upcoming construction phase for this water supply infrastructure project serving the Navajo Nation and surrounding regions.

2. Survey control points provided by Four Corners Construction Office dated 06/26/2024.

3. All control points are shown in New Mexico State Plane Coordinate

System, West Zone (NAD83) horizontal datum. A grid to ground scale factor of 1.000286319627 was used. All distances shown on this drawing are in ground.

4. Reference Specifications for fire hydrant information. Install (2) guard posts on the south side of the fire hydrant, provide 48" minimum clearance from the fire hydrant to the guard post. Install guard posts to avoid conflict with the fire hydrant valve access and the fire hydrant lateral. See 40-D-60002 for detail.

5. Reference Structural drawings for concrete apron information.

6. Line and curve table dimensions are labeled to the concrete pan centerline.

7. Drawing numbers are 1695-D-XXXXX unless otherwise specified.

GENERAL NOTES

1. General Notes, Symbols, Abbreviations, and Pipe Classification apply to all plan and profile drawings.

2. Stations are approximate and may be varied as directed.

3. Minimum earth cover over the top of the pipe shall be 3.5 feet unless the line pipe is at an existing wash, or at a roadway, and then the minimum cover is 5 feet, unless otherwise noted.

4. Hydraulic grade line elevations (H.G.L. El.) shown are for the design Q of 71 cfs in 42" diameter line pipe at steady state for Reach 1.

5. Unknown elevations and diameters of existing utilities shall be determined by the contractor and reported to the COR in time to allow adjustment of grades and design if required before contractor submits pipe, fittings, and miter bends for approval.

6. Grid based on New Mexico State Coordinate System, West Zone (NAD83) horizontal datum. A grid to ground to grid conversion factor is 1.000286319627 was used.

7. All distances shown on this drawing are in ground.

8. CAUTION: Call New Mexico One Call 811 before you dig.

PIPE CLASSIFICATIONS

The line pipe is designated as 42B425, 42B325, 42D450, etc. The 42 indicates the nominal pipe diameter in inches. The letters B, C, and D denote cover class of 10, 15, and 20 feet respectively, of design earth cover over the top of the pipe. The number 425, 325, etc. denotes the maximum allowable hydrostatic pressure head, in feet, measured at the centerline of the pipe.

NOTES

1. Contractor to verify existing grades and utilities prior to construction in accordance with the specifications. Notify engineer of any conflicts or discrepancies immediately.

2. All dimensions are in feet unless otherwise noted.

3. Install observation wells in accordance with Contractor's approved submittal.

4. Unwatering to be performed as needed to control seepage, water inflow from excavated slopes, and runoff in accordance with Contractor's approved submittal.

5. The removal and control of water systems shall be installed to avoid interference with earthwork equipment and to allow uninterrupted access to excavated foundation surface.

6. Three evenly spaced 6-in diameter core hole through concrete slab for observation and pressure relief of groundwater. 18-in diameter and 2-ft high segment of PVC to be sealed in place at top of core hole for sediment observation purposes. Add sandbags (2-ft high) and "sump" pump as directed by COR.

7. Post-construction C-B slurry cutoff windows at a maximum 125-foot interval along the alignment and no less than 25 feet away from channel walls.

8. C-B slurry cutoff wall alignment may be adjusted as approved by COR.

NOTES:

1. Contractor to verify existing grades and utilities prior to construction in accordance with the specifications. Notify COR of any conflicts or discrepancies immediately.

2. All dimensions are in feet unless otherwise noted.

3. Unwatering to be performed as needed to control seepage, water inflow from excavated slopes, and runoff in accordance with Contractor's approved submittal.

4. The removal and control of water systems shall be installed to avoid interference with earthwork equipment and to allow uninterrupted access to excavated foundation surface.

5. C-B slurry cutoff wall excavation and base shall extend a minimum of 3.0' below top of bedrock, or as determined by COR in the field, in accordance with the specifications.

6. Top of bedrock shown on drawings does not include decomposed materials overlying bedrock. See specification 53 10 00 for additional information.

7. Trim C-B slurry cutoff wall to depth of approximately 2.5 feet (El. 5094.5) below grade prior to placing slurry cutoff wall cap, in accordance with specification section 31 56 20 Cement-Bentonite Slurry Cutoff Wall.

8. C-B slurry cutoff wall cap shall consist of compacted backfill in accordance with specification section 31 23 10 Earthwork for Site and Structures.

9. For gravel surfacing details see (62037).

10. Protect existing utilities. Carefully excavate adjacent to utilities and structures.

11. Three evenly spaced 6-in diameter core hole through concrete slab for observation and pressure relief of groundwater. 18-in diameter and 2-ft high segment of PVC to be sealed in place at top of core hole for sediment observation purposes. Add sandbags (2-ft high) and "sump" pump as directed by COR. Remove and repair at the completion of associated work.

12. Remove in-situ soils from channel concrete walls and pipeline penetrations and clean sufficiently to achieve a tight seal with C-B slurry cutoff wall. Avoid damaging the existing concrete walls of the channels and existing pipelines.
