The proportional hazards model is applied to a case study water main break database to identify the hazard characteristics in relation to the factors causing breaks for various categories of the pipes. The analysis showed that a distinction could be made as of when a group of the pipes reach constant hazard stage by using the methodology of building the proportional hazards models for multiple pipe breaks introduced inTheory part of this issue. Effects of the environmental factors that affect the pipe failures are also analyzed and physical interpretations of the phenomena are illustrated. The methodology can provide guidelines on determining a category of pipes that needs more preventive rehabilitation or replacements.
