Longest Canadian PipeDiver Inspection: 18.6 km Electromagnetic Inspection for the City of Winnipeg
Bibliographic record
Abstract
The City of Winnipeg retained Pure Technologies, a Xylem brand (Pure Technologies), to conduct a condition assessment of the prestressed concrete cylinder pipe (PCCP) on the 1,650-mm Branch II Aqueduct in Winnipeg, Manitoba. On September 21, 2022, Pure Technologies used its proprietary PipeDiver platform, a non-destructive electromagnetic inspection technology to locate and identify pipes that have broken prestressing wire wraps. The inspection covered a cumulative distance of 18.63 km and spanned a total of 3,826 pipes from the Deacon Water Treatment Plant to the South Cell of the Wilkes Reservoir. Analysis of the data obtained during the inspection determined that 33 pipes in the 1,650-mm Branch II Aqueduct displayed an electromagnetic anomaly consistent with prestressing wire damage, ranging from 5 to 20 broken wire wraps.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
