ABSTRACT
In recent years, significant changes in management and in the attitude to the modernization of contemporary water supply systems (WSS) have been observed. Intensive research development, often conditioned by market needs, has caused a rise in new technologies associated with applied materials, as well as principles, of WSS operations. Technical progress and research development have led to WSS being treated as a complex process. It is necessary to assess the WSS operation rules based on an interdisciplinary approach to its operation analysis. This problem is difficult to solve due to the degree of complexity of WSS. The operation of modern water-pipe networks involves a combination of different fields of knowledge, such as: system engineering, reliability and safety theory, stores and queuing theory, administration of human and material resources, and economics (Denczew & Królikowski 2003, Pollard 2008). The proper realization of the exploitation process should include organization and modernization works, which ensure that the required technical condition of items is met, as well as detailed technical, economical and reliability analyses.
