It has been studied that major drawbacks in formulating the requirements for the reliability of water supply and sewerage systems in existing regulations are related to the fact of their being formulated in the first part of the XXth century. These regulations dont take into account the latest achievements in the reliability theory appeared and developed successfully in the second part of the XXth century. Among these achievements there is a methodologically correct selection of indices for estimating the reliability of complex technical systems. The selection of science-based reliability indices for water supply and sewerage systems and their introduction in the existing regulations is the task of primary importance.
