Research axis territories

The reuse of treated wastewater is integrated in territorial contexts where the management of water resources is a major component of building resilience against climate change. A "reuse-related question" has then to addressed within a given territory and can be declined at different scales (a watershed, a sub-watershed, a city ...) depending on the questions raised. Whatever the territory, the question of the place of water reuse, within the framework of an integrated management of water resources, requires multi-criteria approaches in order to define relevant reuse scenarios. The research carried out within the framework of the territories and water uses axis aims at :

• develop integrated and systemic approaches of territorial reuse to associate the different sources of treated wastewater with all their uses on a given territory;
• define and prioritize the constraints and criteria affecting the water reuse scenarios (economic, environmental, health, technological, multi-use, territory policy, co-benefits ... ) at the scale of a territory;
• integrate the temporal aspects (economic/usage - resources) on the definition of water reuse scenarios;
• to develop multi-criteria decision-making tools to define relevant and viable scenarios of wxater management and reuse;

This scientific axis is strongly linked to the sectors, risks and actors research themes and serves to feed the application axes, whether in urban or rural areas or in southern countries.
