Abstract
The intricate nature of water distribution networks and the challenge of managing seasonal water consumption variation pose a significant hurdle for water utilities striving for low energy consumption. The performance of pumps, which are the backbone of these networks, directly influences the energy required for distributing drinking water. Such conditions are modelled using MIKE+ for the water distribution network of Ebeltoft, Denmark. The waterworks Egedal in the study area provided data regarding pipes, components, and water consumption, among other databases, as input data for the model. In addition, pressure sensors were installed in 5 locations along Ebeltoft for the model calibration and validation stage, and data was downloaded... (More)

In addition, pressure sensors were installed in 5 locations along Ebeltoft for the model calibration and validation stage, and data was downloaded from SCADA. The model calibrated and validated was used as input data to model the 10 % leakage in the pipes. After this, low and high-demand scenarios were simulated to assess the pump’s energy consumption. The pump efficiencies for Zone 2 and Zone 3 were too low compared to Zone 1. Overall, the high-demand scenario had pumps working at increased efficiencies (6 and 7 %) compared to the low season. It was concluded that pumps were overcapacity for Zones 2 and 3. An alternative proposed is to install a pump with lower capacity, at least during the night hours. (Less)
