- Since the last two decades, the water consumption in Germany is decreasing, which
causes the water tanks and pipes in a water supply system to work inefficiently.
This paper proposes an approach for a decision support system, which helps to
decide how to plan new water tanks and resize existing tanks in water supply systems.
The approach uses a combination of network reduction, mathematical optimization
and hydraulic simulation. The mathematical optimization model is a nonconvex Mixed
Integer Quadratically Constrained Program (MIQCP), which is solved by a piecewise
linearization. As this may lead to many binary variables and therefore high computational
times, the size of the water supply system model is reduced before building the
optimization model. By applying several network reduction techniques there may
occur some hydraulic differences between the original network model and the reduced
network model. To make sure that the solution obtained in the optimization process
is feasible in the original water supply system, the solution is verified by a
hydraulic simulation tool.
