Applied research for multi-scale asset management of the Walloon Water Company's drinking water supply network ; Recherche appliquée pour la gestion patrimoniale multi-échelle du réseau d'adduction d'eau potable de la Société wallonne des Eaux
International audience ; The Wallon Water Company (SWDE) and the National Research Institute for Agriculture, Food and the Environment (INRAE) joined forces from 2020 to 2023 to carry out the applied research project entitled ‘multi-scale asset management of drinking water networks’ (GePaME). This scientific program is based on a service-performance driven water infrastructure asset management, mainly in terms of preservation of drinking water resources (control of water losses), continuity of service (control of network failures), quality of water, and service pressure.

International audience ; The Wallon Water Company (SWDE) and the National Research Institute for Agriculture, Food and the Environment (INRAE) joined forces from 2020 to 2023 to carry out the applied research project entitled ‘multi-scale asset management of drinking water networks’ (GePaME). This scientific program is based on a service-performance driven water infrastructure asset management, mainly in terms of preservation of drinking water resources (control of water losses), continuity of service (control of network failures), quality of water, and service pressure. It adopts a multi-scale approach, which considers service performance from the local level (pipe segment) to the territorial level (District Metered Area (DMA), entire system) and from the short term (annual work programing) to the long term (investment strategy for the next decades). This requires being able to assess user vulnerabilities and knowing what elements of the network environment are affected by poor service performance. Furthermore, the methods and tools developed must take into account the operational organization and governance of the SWDE. ; La Société Wallonne des Eaux (SWDE) et l'Institut National de Recherche pour l'Agriculture, l'Alimentation et l'Environnement (INRAE) se sont associés de 2020 à 2023 pour réaliser le projet de recherche appliquée intitulé « Gestion patrimoniale multi-échelle des réseaux d'eau potable » (GePaME) .Ce programme scientifique s'appuie sur une gestion du patrimoine des infrastructures d'eau axée sur la performance des services, principalement en termes de préservation des ressources en eau potable (maîtrise des pertes en eau), de continuité de service (maîtrise des pannes des réseaux), de qualité de l'eau et de pression de service. Il adopte une approche multi-échelle, qui considère la performance du service depuis le niveau local (segment de canalisation) jusqu'au niveau territorial (secteur hydraulique, système complet) et du court terme (programmation annuelle des travaux) au long terme ( ...
