    Abstract: The invention relates to a computer-implemented method for detecting fraud by a consumer in the consumption of a utility, such as water, when an abnormal event in a utility distribution network is detected, comprising obtaining consumption readings (a 1 , a 2 , a 3 , a 4 ) of the utility of the consumer; generating a time-series forecasting model (â 1 , â 2 , â 3 , â 4 ) of the consumption of the consumer; calculating prediction errors (e 1 , e 2 , e 3 , e 4 ) between the time-series forecasting model and the consumption readings before and after the abnormal event; clustering the prediction errors (C1, C2, C3) in time sequences; and detecting that the consumer is potentially committing fraud if the number of clusters of prediction errors is more than one.
