Water critical infrastructures (CIs) are essential for human society, life and health and they can be endangered by physical/cyber threats with severe societal consequences. To address this, STOP-IT assembles a team of major Water Utilities, industrial technology developers, high tech SMEs and top EU R&D providers. It organizes communities of practice for water systems protection to identify current and future risk landscapes and to co-develop an all-hazards risk management framework for the physical and cyber protection of water CIs. Prevention, Detection, Response and Mitigation of relevant risks at strategic, tactical and operational levels of planning will be taken into account to generate modular solutions (technologies, tools and guidelines) and an integrated software platform. STOP-IT solutions are based on: a) mature technologies improved via their combination and embedment (incl. public warning systems, smart locks) and b) novel technologies whose TRL will be increased (incl. cyber threat incident services, secure wireless sensor communications modules, context-aware anomaly detection technologies; fault-tolerant control strategies for SCADA integrated sensors, high-volume real-time sensor data protection via blockchain schemes; authorization engines; irregular human detection using new computer vision methods and WiFi and efficient water contamination detection algorithms). STOP-IT solutions are demonstrated through a front-runner/follower approach where 4 advanced utilities, Aigües de Barcelona (ES), Berliner Wasserbetriebe (DE), MEKOROT (IL) and Oslo VAV (NO) are twinned with 4 less advanced, but ambitious ones, to stimulate mutual learning, transfer and uptake. Building on this solid basis STOP-IT delivers high impact through the creation of hands-on training, best practice guidelines, support for certification and standardization as well as by fostering market opportunities, also leveraging the EU water technology platform's multi-stakeholder network.

digital-water.city’s (DWC) main goal is to boost the integrated management of waters systems in five major European urban and peri-urban areas, Berlin, Milan, Copenhagen, Paris and Sofia, by leveraging the potential of data and smart digital technologies. DWC will create linkages between the digital and the physical worlds by developing and demonstrating 18 advanced digital solutions to address current and future water-related challenges; namely the protection of human health, the increase of performance and return on investment of water infrastructures and the involvement of citizens in urban water management. Areas of application of DWC digital solutions range from groundwater management, sewer maintenance and operation, wastewater treatment and reuse to urban bathing water management. DWC combines cutting-edge digital technologies such as augmented reality, open source software, cloud computing, real-time sensors, artificial intelligence, predictive analytics and decision support systems. DWC integrates the development of digital solutions in a dedicated guiding protocol to cover the existing gaps regarding ICT governance, interoperability, ontology and cybersecurity. Ultimately, DWC will provide an interoperable free flow of information among stakeholders and across the water value chain. DWC will generate the necessary conditions for co-creation and open innovation by the establishment of Community of Practices aiming at integrating stakeholder knowledge, ensuring the transferability of the digital solutions in other European or international contexts, supporting knowledge transfer beyond DWC and creating durable binding between European cities. The large scale assessment and communication of the benefits provided by the digital solutions in five major cities will serve as lighthouse, raising the awareness of European cities for a necessary digital transformation, and opening new market opportunities for DWC partners and European providers of digital solutions.

The vision of REFLOW is to develop circular and regenerative cities through the re-localisation of production and the re-configuration of material flows at different scales. More specifically, it will use Fab Labs and makerspaces as catalysers of a systemic change in urban and peri-urban environments, which enable, visualize and regulate “four freedoms”: free movement of materials, people, (technological) knowledge and commons, in order to reduce materials consumption, maximize multifunctional use of (public) spaces and envisage regenerative practices. Concretely, REFLOW aims at providing realistic best practices aligning market and government needs in order to create favourable conditions for the public and private sector to adopt circular principles. In order to provide critical examples of ways in which cities can adopt a CE model and reach the 2030 Sustainable Development Goals, REFLOW will create new CE business models (Distributed Design Market model, On-Demand System, Corporate Hacking and Corporate Pyramid) within 6 pilot cities (Amsterdam, Berlin, Milan, Paris, Vejle and Cluj-Napoca) and assess their social, environmental and economic impact. The project will make use of blockchain technologies in order to incentivise the circular practices in local ecosystems and data visualisation tools to enable continuous monitoring and optimisation of “urban metabolic” processes and rapid interventions management. Networks of sensors, urban computing and geo-localisation will capture data ensuring accuracy, integrity and interoperability of relevant data infrastructures, while data visualisation and standard templates will be available for effective communication, public consultation, and exchange of experiences.

The AquaNES project will catalyse innovations in water and wastewater treatment processes and management through improved combinations of natural and engineered components. Among the demonstrated solutions are natural treatment processes such as bank filtration (BF), managed aquifer recharge (MAR) and constructed wetlands (CW) plus engineered pre- and post-treatment options. The project focuses on 13 demonstration sites in Europe, India and Israel covering a repre-sentative range of regional, climatic, and hydrogeological conditions in which different combined natural-engineered treatment systems (cNES) will be demonstrated through active collaboration of knowledge and technology providers, water utilities and end-users. Our specific objectives are • to demonstrate the benefits of post-treatment options such as membranes, activated carbon and ozonation after bank filtration for the production of safe drinking water • to validate the treatment and storage capacity of soil-aquifer systems in combination with oxidative pre-treatments • to demonstrate the combination of constructed wetlands with different technical post- or pre-treatment options (ozone or bioreactor systems) as a wastewater treatment option • to evidence reductions in operating costs and energy consumption • to test a robust risk assessment framework for cNES • to deliver design guidance for cNES informed by industrial or near-industrial scale expe-riences • to identify and profile new market opportunities in Europe and overseas for cNES The AquaNES project will demonstrate combined natural-engineered treatment systems as sus-tainable adaptations to issues such as water scarcity, excess water in cities and micro-pollutants in the water cycle. It will thus have impact across the EIP Water’s thematic priorities and cross-cutting issues, particularly on ‘Water reuse & recycling’, ‘Water and wastewater treatment’, ‘Water-energy nexus’, ‘Ecosystem services’, ‘Water governance’, and ‘DSS & monitoring’.
