Navajo Gallup Water Supply Project Pipeline Design and Construction Evaluation
Bibliographic record
Abstract
The Navajo Gallup water supply project reach 24.1/25 project will convey water from the San Juan River to four Navajo Nation (Nation) communities in northwest New Mexico. These Native American communities are among the most water-underserved in the United States. The project includes 13.7 miles of 14- and 10-inch pipeline and a pump station with a capacity of 1,500 gallons per minute. The Nation elected to use PVC for the transmission line, and also utilized fused PVC pipe (FPVCP) for the first time. FPVCP was used for joint restraint sections and for sections of the line where pipe joints were undesirable. This included arroyo crossings, locations of potential contamination, and areas of potential down-surge pressures. This paper will discuss the rationale, benefits, costs, and trade-offs of using FPVCP to provide thrust restraint, reduce risk of pipe failure due to soil erosion, and mitigate risk of contamination at pipe joints. Both advantages and disadvantages of FPVCP will be discussed, as well as lessons learned during construction and design aspects that may be improved upon in future designs using FPVCP as part of typical buried PVC pipe systems.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
