Prioritizing Water Distribution and Sewer Network Maintenance Activities

Asset management in water supply and sewerage infrastructures seeks correct planning and prioritization of the maintenance activities on their network elements. To determine the replacement priority for each network asset, an original priority model is utilized. It is based on a risk index that integrates both the probability and consequences of failure. Besides, when designing and performing work programs, water companies generally abide by the street's topography and other urban elements, such as complete streets or street sections. This work considers street sections between the two nearest intersections as the operational unit.
