are tested against several true-to-life usage cases (e.g., contamination of a municipal storage tank, contamination of a major water trunk line, contamination of a local supply line) using several families of contaminants such as organic compounds, toxic waste, and radioactive material. Trials and measurements of individual components of the system as well as the entire completed system are performed in special hydraulic test networks set up in three different water utilities. Applying the SAFEWATER system or any component thereof will enhance a water utility's ability to rapidly detect a contamination event, analyze its repercussions using real-time hydraulic models, mitigate the damage using simulation tools and swift operating procedures, and deal more effectively with the event using a comprehensive event management tool. Figure 3 provides an overview of the structure of the SAFEWATER system. The key module is the Event Management System (EMS), which handles incoming events and provides decision support in case of a crisis (as well as for routine operations). The Event Detection System (EDS) breaks ground by detecting potentially dangerous constellations of water quality parameters currently undetectable. These constellations may indicate a contamination of the drinking water network, or a so-far-unknown operational effect. In case of an event, it is important to quickly provide decision support regarding the best mitigation measures (e.g., opening/closing of valves). In the SAFEWATER system the hydraulic and water quality state of the network is simulated in real time. In case of an event, online response tools can predict the spread of the contamination and calculate optimal measures to minimize the impact of the contamination. The simulators can also be used in an offline context in order to train the operational staff. Furthermore, the simulators are used in order to train the event detection system. Within the SAFEWATER project, enhanced CBRN sensors are also being developed to provide the ability for early detection of CBRN contaminations. Project ResiWater Innovative secure sensor networks and model-based assessment tools for increased resilience of water infrastructures The German-French project ResiWater (2015 to 2018) aims to develop tools to prepare water utilities for crisis management and enhance their resilience with regard to three specific case studies: (1) collapse of water distribution systems, (2) water quality deterioration, and (3) cascade effects among water, energy, and IT infrastructures. The aim of this project is to develop enhanced sensors and secure sensor networks, self-learning monitoring tools, robust simulation models, and vulnerability and resilience 18 wateronline.com n Water Innovations WATERQUALITYANALYSIS Figure 2.
