EFFINET addresses three main management problems in urban water system: optimal operational control, real-time monitoring and demand forecasting. Real-time optimal control deals with operating the main flow and pressure actuators to meet demands using the most sustainable sources and minimizing electricity costs through model predictive control techniques. Real-time monitoring of water quantity and quality refers to the continuous detection and location of leakage and or water quality breaches. Demand forecasting is based on smart metering techniques and includes modeling of consumption patterns as well as a service of communication to consumers. The project will provide an integrated software platform and two real-life pilots in Barcelona (Spain) and Lemesos (Cyprus).
