Water Tank Optimization Tool (WaTaOpt)


The Water Tank Optimization tool can be used to support the planning process for tanks in a water distribution system. It helps to decide at which places in the network a tank should exist and which dimension this tanks should have. To achieve a cost minimal solution a mathematical optimization model is used. This model can be solved via various optimization algorithms. In order to reduce solution times, WaTaOpt provides pre-processing techniques that reduce the size of the network model. The obtained solution is evaluated by a hydraulic simulation. If the solution is not satisfying, a modification process is performed until the solution is satisfying.
