This paper proposes a new sensor placement approach for leak location in water
distribution networks (WDNs). The sensor placement problem is formulated as an integer
optimization problem. The optimization criterion consists in minimizing the number of non-
isolable leaks according to the isolability criteria introduced. Because of the large size and
non-linear integer nature of the resulting optimization problem, genetic algorithms (GAs) are
used as the solution approach. The obtained results are compared with a semi-exhaustive …

In this paper, a sensor placement approach to improve the leak location in water distribution
networks is proposed when the leak signature space (LSS) method is used. The sensor
placement problem is formulated as an integer optimization problem where the criterion to
be minimized is the number of overlapping signature domains computed from the original
LSS representation. First, a semi-exhaustive search approach based on a lazy evaluation
mechanism ensures optimal placement in the case of low complexity scenarios. For more …
