This policy paper is part of Project Ô − Demonstration of planning and technology tools for a circular, integrated, and symbiotic use of water, and of WP3 dedicated to the Integrated water management, planning and circular economy (CE). It assesses the integration of water and land related issues in national CE action plans of a set of European Union (EU) member states. <br> Water policies need to tackle the impact of water use by forging new objectives of sustainability and resilience. These objectives, heightened by increasing problems of water scarcity, converge with the CE concept that urges to go beyond linear “take-make-dispose” models and favours closed loops of resources such as materials or other environmental resources, like water. Water reuse has been pursued by several policy approaches, including a sectorial approach by means of water policy, or, expectedly, an integrated approach, by means of a CE policy. Both should be intrinsically related to spatial planning, because the implementation of a water reuse system, with new water loops, is influenced by the territorial allocation of different economic activities and may be conditioned by spatial planning regulations and the related decision-making processes.
