Abstract: 

In this paper, we demonstrate the application of different sensor location optimization strategies in drinking water distribution networks, with aims such as maximization of distribution network coverage with redundancy and optimization of contamination source identification. We present and compare results of these different approaches applied to hydraulic models of a real drinking water distribution network in the Netherlands. The selection of results presented in this paper illustrates that it is important for a water company to decide what its main objective is with regard to water quality sensors before installing them in the field. Different optimization criteria for their spatial configuration result in very different configurations, which may perform well for one purpose but much less so for another. However, some sets of objectives are compatible in the sense that a configuration optimized for one objective also performs well for the other.
