The Optimum Dimension of Water Storage Tanks in Urban Water Supply Systems using a Dynamic Model

The pump stations are on of the main energy consumers in urban water supply systems, Therefore, it is very important to minimize waste of energy in these stations. Today, pumps are running at their highest possible mechanical efficiency due to their matured technology; As a result, efficiency improvement should be considered in other elements of the network. Among the constituting elements of urban water supply systems, storage tanks play an important role and significant energy saving can be achieved by optimizing their design. In this paper, capacities and dimensions of water storage tanks in different operating conditions in an actual water pump station have been simulated by dynamic modeling in Simulink/MATLAB software. The results could be used as recommendations for optimization of energy saving in water storage tanks in pump stations, the number of operating pumps in the network, the volume of stored water and so on in different operating conditions
