Abstract
Water distribution systems (WDSs) face numerous challenges in providing service to their customers. An especially difficult challenge occurs when several pipes in the system fail simultaneously. Simultaneous failure is more likely to occur in older networks or systems located in harsh climatic conditions. Previous studies have focused on WDS reliability when pipes fail individually. The current research proposes a technique to determine the reliability of a WDS experiencing different degrees of simultaneous pipe failure and to assess errors in reliability that occur when an inappropriate level of simultaneous failure is assumed. The model was applied to two case studies including a hypothetical small system and an actual WDS. Comparing the various states of reliability provided valuable information about system sensitivity to simultaneous multipipe failures. Results demonstrated that a system may be able to achieve a higher level of reliability if more realistic expectations of simultaneous failure are assumed.

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
