Yves Le Gat – Researcher in Applied Statistics for Infrastructure Asset Management

Yves Le Gat conducts research as part of the Gestion Patrimoniale des Infrastructures liées à l’Eau team. This team of a dozen people works in an interdisciplinary environment, combining engineering sciences, sociology and economics.

Yves Le Gat builds probabilistic models that enable local authorities to anticipate the deterioration of water and wastewater networks with a view to prioritising their renewal. The models simulate the impact of a management decision – to repair, renew, reinforce or relocate – in the short, medium and long term on the network and its users. Using a multidisciplinary approach, the simulations measure the impact of management choices (budget, prioritisation of works, coordination with third-party infrastructure) on the quality of the service provided to users (continuity, preservation of water resources, quality of the water distributed). Asset management is an international concern that has led the team to work on major European projects in collaboration with a number of local authorities organising water and wastewater services.

In addition to targeted research, the team also carries out consultancy work in French overseas territories and abroad, as well as offering training.
