Drinking Water distribution systems as well as other technical networks represent an important accounting capital. Water networks are an assembly of technical devices, most of them are buried. This makes their diagnosis more difficult and requires the implementation of a policy, known by «asset management. This requires planned actions in the short, medium and long term. It aims to describe the state of the asset by developing specific tools in a first time and plan the actions needed to maintain its state in a second phase. The current research deals with the problematic of pipes prioritisation for rehabilitation. The developed approach is based on the discrimination of pipes by a spatial and temporal analysis starting from a simple idea: the diagnosis is often unaware dimensions: topology and evolution of failures pattern. Thus, detailed approach provides a holistic vision of the network by identifying areas with high failures, called "hotspots" and their evolution over time. Therefore, this research allows a visual representation using the network topology; such representation provides a resolution of the network and can be used to evaluate, a priori, the effectiveness of the rehabilitation policies according to their incidence on hotspots' decrease.
