The GPIE team (Gestion Patrimoniale des Infrastructures liées à l'Eau)

In France, the construction of water networks was essentially carried out from the end of the 19th century to the present day and reached its peak in the 1970s and 1980s.

Now that the initial service works have been completed, the public authorities and the managers of these networks are faced with the question of securing them.

This problem, which concerns both the management of water resources, the sustainability of infrastructures and health safety, leads to the implementation of a patrimonial management.

Water-related infrastructures constitute a high-value asset with a long service life, and their management must therefore be part of a long-term approach that takes into account changes in their environment, particularly those linked to global changes and new technologies.

It is at the crossroads of technical, organizational (service), economic and financial (costs and benefits), environmental (resources) and societal (territorial governance, users) issues, which call for responses from interdisciplinary approaches, mobilizing engineering sciences, mathematics and human and social sciences.

The research conducted within the GPIE team aims to produce knowledge, methods and tools to help public authorities and managers build optimized strategies for the management of water-related infrastructures.

They are organized around three axes: the evaluation and control of performance and risks related to infrastructures, the optimization of asset management strategies within the framework of a long-term vision, and the design and development of operational methods and tools.
