This work proposes a mechanism able to automatically cat- egorize different types of faults occurring in critical infrastructures and especially water distribution networks. The mechanism models the rela- tionship exhibited among the sensor datastreams based on the assump- tion that its pattern alters depending on the fault type. The first phase includes linear time invariant modeling which outputs a parameters vec- tor. At the second phase the evolution of the parameter vectors is cap- tured via hidden Markov modeling. The methodology is applied on data coming from the water distribution network of the city of Barcelona. The corpus contains a vast amount of data representative of nine net- work states. The nominal is included for enabling fault detection. The achieved classification rates are quite encouraging.
