About this file

Written by GovTribe AI · May 16, 2025

This document contains detailed engineering and architectural drawings for the Navajo-Gallup Water Supply Project's Pumping Plant No. 1, located in San Juan County, New Mexico. The comprehensive set of technical drawings covers multiple aspects of the pumping plant, including civil site details, structural excavation, masonry design, grading plans, and manifold piping layouts. The plant will include multiple pumping units (Units 1-7), air chambers, suction and discharge manifolds, and supporting infrastructure such as electrical and HVAC enclosures, with a primary datum elevation of 5076.50 feet.

The drawings specify intricate technical specifications for the facility, including 42-inch standard steel piping, butterfly valves, air release valves, blowoff valves, and complex piping configurations. The site includes detailed grading plans with specific elevation changes, riprap berms, concrete pans, and drainage considerations. The plant is designed with multiple mechanical and electrical components, including vertical turbine pumps, air compressors, and control systems, with provisions for instrumentation, level monitoring, and system controls. The project is being executed by the Bureau of Reclamation and is part of the larger Navajo-Gallup Water Supply Project, aimed at providing water infrastructure for the Navajo Nation in New Mexico.

SITE PLAN

DENVER, CO

1695-D-61860

NOTES:

1. Contractor to provide erosion and sediment control for the site until final stabilization is achieved. Erosion control activities shall include but are not limited to:

1.a. Installing a silt fence around perimeter of disturbed areas.

1.b. Seed and mulch disturbed areas outside the proposed chainlink fence and riprap areas for permanent soil stabilization.

1.c. Install erosion control blankets on disturbed soils with 4:1 slopes or greater.

2. Reference Structural drawings for concrete apron information

3. See 40-D-60002 for guard post details.

4. Line and curve table dimensions and bearings are labeled to the flowline of the concrete pans and the gravel yard extents.

5. 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.

6. See (61867) for concrete pan, concrete chase, cutoff wall, and gravel surfacing details.

7. Reference Specifications for fire hydrant information. Install (4) guard posts around the fire hydrant, provide 48" minimum clearance from fire hydrant to guard posts. Install guard posts to avoid conflict with the fire hydrant valve access and fire hydrant lateral.

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

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. Yard elevations are shown to top of gravel unless otherwise specified.

3. Provide 6% minimum grade away from the building in gravel areas for 10' minimum.

4. Slope concrete stoops and aprons away from the building at 2.0% slope. Re: Structural for grading information within enclosures.

5. Install erosion control blankets on disturbed slopes sloped at 4:1 or greater.

6. All vertical elevations are based on the NAVD88 vertical datum.

7. Contours shown are based off of lidar data provided by Atlantic and survey elevations provided by the Four

Corners Construction Office.

8. 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.

9. Improvements to the main road and the existing CMP culvert beneath the main road are shown on drawings

61869 & 61870.

10. Taper the gravel surface from flush with the concrete walk to a 6" min. depth to provide an outfall for the trench drain. Paint the edge and top 4" of the concrete walk's edge where the vertical clearance from concrete to gravel is less than 6".

11. See (61860) for locations of riprap berms where soil and gravel shall be used to fill riprap rock voids.

12. See 40-D-6552 for details regarding bedding and embedment placement about RCP Culverts. Refer to

Specifications for CLSM bedding and embedment depth requirements.

NOTES

1. At angle points that do not require miter bends, long radius curves

(vertical and horizontal) shall be constructed by pulling joints.

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 or traffic, and then the minimum cover is 5 feet, unless otherwise noted.

4. All joints are to be restrained under wash crossings between the stations identified on the plan and profile.

5. Where the line pipe crosses an existing pipe, a minimum clear distance of 2 feet outside to outside between line pipe and existing pipe shall be provided unless otherwise directed. The backfill between the crossing pipelines shall be controlled low strength material (CLSM) as stated in the specifications.

6. Hydraulic grade line elevations (H.G.L. El.) shown are for the maximum static HGL upstream of Pumping Plant 1 on Reach 2.

The HGL downstream of the Pumping Plant 1 on Reach 2 is design Q of 71 cfs at steady state.

7. 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.

8. Grid based on New Mexico State Coordinate System West Zone.

9. Reach 2 and 3 Ground to grid conversion factor is 0.999713762328.

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

PIPE CLASSIFICATIONS

The line pipe is designated as 36B425, 36B325, 36D450, etc.

The 36 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 letter K denotes steep pipe sections. The letters HDD denotes Horizontal Directional Drill. The number 425, 325, etc. denotes the maximum allowable hydrostatic pressure head, in feet, measured at the centerline of the pipe.

PLAN

DENVER, CO

1695-D-61868

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. Profile view elevations are shown to top of gravel unless otherwise specified.

3. For improvements to the main road and the existing CMP culvert beneath the main road, see drawings (61869) and (61870).

4. All vertical elevations are based on the NAVD88 vertical datum.

5. Contours shown are based off of lidar data provided by Atlantic and survey elevations provided by the Four Corners Construction

Office. Cross sections of the existing drainage channel are based off of survey elevations provided by FCCO on 1/2/24.

6. 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.

7. A 100-year flowrate of 24.8 cfs was calculated for the off-site basin tributary to the existing drainage ditch. The off-site basin flowrate was analyzed to determine the capacity and 100-year water surface elevation (WSEL) in the ditch. The peak flowrate discharged from the Pumping Plant 1 site is expected to occur before the peak flow from the off-site basin.

MISCELLANEOUS METALWORK

For abbreviations, concrete symbols, and additional concrete outline general notes, see 40-D-60003.

Structural design for cast-in-place structural concrete is based on concrete with a minimum compressive strength of 4,500 pounds per square inch at 28 days.

Dimensions not shown are the same dimensions for identical details and sections shown elsewhere on the drawings.

Where concrete with varying thickness is shown on the drawings, vary thickness of concrete uniformly between dimensions and elevations shown.

Pipe sleeves and embedded piping 12 inches in diameter and larger are shown on the outline drawings. Smaller diameter pipe sleeves or piping may or may not be shown.

Not all embedded items are shown on the outline drawings.

Before placing concrete on grade, make sure that all buried material below the concrete is in place.

For details of method of building forms for successive lifts, see 40-D-5246.

For details of construction and contraction joints, see 40-D-5247.

All horizontal construction joints shall be thoroughly cleaned and roughened to a full amplitude of approximately 1/4 inch.
