This Deliverable is inserted in the Work Package 3 of Project Ô dedicated to ‘Integrated water management, planning and circular economy’. It studies the main features of the policy and planning set-up in place of the four demo sites of Project Ô. For this purpose, it develops an analysis primarily focused on the circular economy policies, water resources planning and spatial planning contexts. It seeks to understand how the current set-up, as established by policy and planning documents, are prepared to accommodate innovative water loops to foster water circular economy (WCE). In the end, it aims to contribute to the identification of major drivers and barriers for the transition to WCE in the perspective of water reuse. The water-land-use nexus approach for WCE requires integrative resource approaches, enabled by policy and decision-making instruments and processes. Alternative water systems, when altering outer water loops, water producers and users, may challenge policy and planning decision making and related tools. Are these concepts on the way to becoming institutionalised in the national policies for circular economy (CE) and in the water resources and spatial planning documents? This Deliverable explores this research question.
