AB - Water utilities face a challenge in maintaining a good quality ofservice under a wide range of operational management and failure conditions.Tools for assessing the resilience of water distribution networks are thereforeessential for both operational and maintenance optimization. In this paper, anovel graph-theoretic approach for the assessment of resilience for large scalewater distribution networks is presented. This is of great importance for themanagement of large scale water distribution systems, most models containingup to hundreds of thousands of pipes and nodes. The proposed frameworkis mainly based on quantifying the redundancy and capacity of all possibleroutes from demand nodes to their supply sources. This approach works wellwith large network sizes since it does not rely on precise hydraulic simulations,which require complex calibration processes and computation, while remainingmeaningful from a physical and a topological point of view. The proposal isalso tailored for the analysis of sectorised networks through a novel multiscalemethod for analysing connectivity, which is successfully tested in operationalutility network models made of more than 100,000 nodes and 110,000 pipes.
