About this file

Written by GovTribe AI · Aug 4, 2026

This file is a technical drawing document (22" x 34" format) for the NGWSP Cutter Lateral Reach 21 Booster Plant project dated June 23, 2025. The drawing serves as part of the 90% draft specifications and design documentation for the proposed booster plant facility located approximately 26 miles south of Bloomfield, New Mexico in San Juan County. The booster plant is a critical component of the larger Navajo-Gallup Water Supply Project (NGWSP), which aims to convey municipal and industrial water supply from the San Juan River across approximately 300 miles of pipeline infrastructure serving the eastern Navajo Nation, southwestern Jicarilla Apache Nation, and the city of Gallup, New Mexico.

This drawing is issued by the U.S. Bureau of Reclamation's Upper Colorado Basin Region and Four Corners Construction Office as part of a Sources Sought notice (Solicitation Number 140R4026B0003) designed to identify small business contractors capable of serving as prime contractors for the booster plant construction. The NAICS code 237110 (Water and Sewer Line and Related Structures Construction) applies, with a small business size standard of $45.0 million. The technical documentation provided supports the agency's evaluation of potential contractor capabilities and bonding requirements, and will inform the government's acquisition strategy for a potential future total small business set-aside solicitation.

NOTES

1. Sloping, shoring, percent of compaction, and benching shall be in accordance with the Specifications.

2. Provide erosion control blankets on slopes greater than or equal to 4:1.

3. Contractor shall verify existing grades and utilities prior to construction in accordance with the Specifications.

Notify resident engineer immediately of any conflicts or discrepancies.

4. Spot elevations are shown to top of gravel, top of finished grade, or flowline unless otherwise specified.

5. Contractor to extend existing tank's perimeter drain outfall pipe to daylight and provide positive drainage.

6. See specifications for geotextile fabric information.

7. Clear and screen area for vegetation, large rocks, etc.

before grading and backfilling. See Specifications for additional information.

Swale should connect to stilling basin. Stilling basin on 62347 should be added to 62347

Stilling basin plan shape should be the saem as on sheet 62347

Note 2. Change from 4:1 to 6:1.

Note 6 Add geomembrane

Add coir wattles at the mid-point and toe of all tank site sideslopes.

Need to add installation details. I think NGWSP 4A and 4B has the latest drawings.

1. Drawing not to scale.

2. O.D is the outside diameter, in inches, of the pipe actually installed.

3. Dn is the nominal pipe diameter.

4. CLSM is Controlled Low Strength Material. See specifications for details.

5. Sloping, shoring, and benching shall be in accordance with Reclamation

Safety and Health Standards.

6. CLSM is required in the bedding for all pipe types.

7. Warning tape and tracer wire not shown for plastic pipe types, but are required. See specifications for details.

8. Other material may be submitted in lieu of soil pads for approval. Soil pad materials must not exceed the compressive strength of the CLSM.

9. CLSM is required for the embedment when there is expansive soils and the native trench material's plastic index exceeds 25 as listed in Table

1.2 of Reclamation's Earth Manual.

10. CLSM is required for the embedment when saturated soil is encountered in the pipe trench.

11. Install pipe based on these specifications or pipe manufacturer's, whichever is more stringent.

NATIVE MATERIAL PROPERTIES

MATERIAL TYPE 1 - Typical trench wall materials would be rock; materials described as shale, claystone, mudstone, siltstone or sandstone; highly cemented soils; sands, gravels, and silty or clayey material with in-place densities of 95% Standard Proctor or higher.

MATERIAL TYPE 2 - Typical trench wall materials would include silty or clayey material or sands and gravels with in-place densities between 85% and 95% Standard Proctor.

MATERIAL TYPE 3 - Typical trench wall materials would include elastic silts, low density silty or clayey soils, or low-density cohesionless soils with a density below 85% Standard Proctor.

Trench Material Type locations, based on the above Native Material Properties and geology investigation, have been identified and correspond to minimum side clearance widths listed in the Side Clearance Table. Material Type 1's inferred bedrock surface is shown in the profile on drawings. Material Types 2 and 3 locations are listed in Table 31 23 22A in the specifications.
