This paper presents a methodology to detect real water losses in urban water networks. The
proposed method is based on the combined use of the DMA economical water balance confidence
intervals for a period of time longer than a month (a trimester, semester or year) with appropriated night
flow ratio intervals. This method allows distinguishing between real and apparent water losses in a given
DMA. The use of uncertainty models allows taking into account measurement uncertainty of the flow
data sensors. The use of different periods of time allows the stabilization of the results. This methodology
is illustrated in a DMA of the Barcelona water distribution network using real data.
