Criticality assessment model for water distribution networks

The Canadian Infrastructure Report Card of 2016 rates the water system as 'good', but with 29% of pipelines in fair to poor condition, demanding urgent repairs costing $60 billion. Municipalities struggle to prioritise asset rehabilitation due to financial constraints. This study aims to develop a criticality model for water pipeline prediction, integrating expert insights. Three dimensions - economic, environmental/operational, and social - are assessed using the paprika technique. Sensitivity analysis identifies key factors influencing criticality. The model combines criticality and performance indexes to form a priority index, aiding municipalities in strategic capital planning. By pinpointing critical areas requiring immediate attention, this model enhances infrastructure management decision making.
