Abstract
Leakage of water distribution networks is the most common reason of undesirable losses of potable water. Problems associated with water main leaks pose growing concern around the globe. These problems include water and energy loss, in addition to the risk it poses to structural damage of adjacent properties. In current practice, not all water leaks can be detected in a timely and cost effective manner. This paper presents a study conducted for detection of water leaks in underground pipelines, and identification of their respective locations using thermography infrared camera. The paper describes the field work and the experimental protocol which were carried out over 2 years in three different locations in greater Montréal (Canada) area in order to investigate factors that affect the applicability and limitations of using IR camera in water leak detection. These factors beyond those studied in previous work carried out by American Water Works Association and National Research Council. The paper presents a model developed to determine approximate location of leaks in water mains. The developed model was then applied successfully to detect and locate leaks in water mains in fall and spring seasons. It failed, however, to detect leaks in the summer and winter due to high pavement temperature and the snow coverage, respectively.

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 it
