This paper outlines one possible approach to the comprehensive technical audit of water distribution networks. Based on practical experience, discussions with domestic and foreign operators, and knowledge gained from international projects, the paper proposes technical indicators, methods for their determination and criteria for evaluating the values reached by these indicators. The proposed procedure is based on the FMEA (Failure Modes Effects and Analysis) method, used in the general theory of risk analysis. The results of this method were employed to evaluate the technical condition of the water distribution network in Pilsen, Czech Republic.
