Cover Story: Water distribution system monitoring needs advanced real-time control technologies to achieve maximum operational efficiency. This work proposes a state estimation methodology that enables inferring the operating speed of the system’s pumping stations from the monitored pressure and flow rate measurements across the system. The approach uses graph convolutional neural network theory linked to hydraulic models that generate a digital twin of the water system. It is validated on two benchmark hydraulic networks, where the proposed model effectively predicts the system’s state. The results of the evaluation metrics reflect a high predictive ability and that the prediction results adequately represent real data. View this paper
