Policy and legislative barriers to close water-related loops in innovative small water and wastewater systems in Europe: a critical analysis

Members or HYDROUSA consortium (Marche Polytechnic university, Istanbul University, National Technical University of Athens, SEMIDE) published an article on Elsivier Journal of cleaner production. The paper analyzes the current policy and legislations related to water supply, wastewater treatment, water reuse and resource valorization within the context of decentralized state-of-the-art technologies applied in rural areas. The drawbacks in the current EU legislation that set barriers to close water-related loops in European countries are highlighted. A regulatory fitness check was applied to each type of loop to identify the key factors to accomplish the legislative compliance, and financing pathways were further evaluated at the EU level. As a possible solution, further development of an innovation deal approach is recommended to address the environmental, regulatory and financial gaps in water management through an integrated framework, providing ad-hoc policies and prescriptions for sustainable reuse of all water resources
