FIWARE is a smart solution platform, funded by the EC (2011-16) as a major flagship PPP, to support SMEs and developers in creating the next generation of internet services, as the main ecosystem for Smart City initiatives for cross-domain data exchange/cooperation and for the NGI initiative. So far little progress has been made on developing specific water-related applications using FIWARE, due to fragmentation of the water sector, restrained by licensed platforms and lagging behind other sectors (e.g. telecommunications) regarding interoperability, standardisation, cross-domain cooperation and data exchange. Fiware4Water intends to link the water sector to FIWARE by demonstrating its capabilities and the potential of its interoperable and standardised interfaces for both water sector end-users (cities, water utilities, water authorities, citizens and consumers), and solution providers (private utilities, SMEs, developers). Specifically we will demonstrate it is non-intrusive and integrates well with legacy systems. In addition to building modular applications using FIWARE and open API architecture for the real time management of water systems, Fiware4Water also builds upon distributed intelligence and low level analytics (smart meters, advanced water quality sensors) to increase the economic (improved performance) and societal (interaction with the users, con-consensus) efficiency of water systems and social acceptability of digital water, by adopting a 2-Tier approach: (a) building and demonstrating four Demo Cases as complementary and exemplary paradigms across the water value chain (Tier#1); (b) promoting an EU and global network of followers, for digital water and FIWARE (cities, municipalities, water authorities, citizens, SMEs, developers) with three complementary Demo Networks (Tier#2). The scope is to create the Fiware4Water ecosystem, demonstrating its technical, social and business innovative potential at a global level, boosting innovation for water.

IDEATION (InlanD watErs in the digitAl Twin OceaN) aims to prepare the development of the digital twin of the inland waters (rivers, lakes, reservoirs, wetlands, snow, and ice) addressing activities to be developed and to make it integrated and interoperable with the DTO for a unified digital twin of ocean and waters (addressing the hydrosphere as a whole). IDEATION will be based on a cross-border cooperation, involvement, and commitment of stakeholders at European level by following the Water-oriented Living Labs (WoLLs) approach. Stakeholders will be engaged via Multi-Stakeholder Forums (MSF), using a range of different engagement methodologies (e.g., focus groups, workshops, interviews, questionnaires) depending on goals of the engagement and specificities of the context. A comprehensive review will be performed to make an open knowledge inventory for inland water systems (OpenKIWAS). IDEATION will co-design the IDEATION reference architecture defining a set of building blocks, interfaces and standards to make data, models and technologies interoperable and integrable with the DTO. Putting together all the results from the MSF, OpenKIWAS, and the IDEATION reference architecture, a roadmap for the integration of inland waters in the Digital Twin Ocean will be created providing a preliminary breakdown of the work, with priorities of implementation, into a stepped approach. The consortium members have high experience on EU project coordination and participation, the majority of them already worked together in research projects.

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’.
