Water supply system reliability management

The necessity of using modern techniques of monitoring, supervision and protection of particular subsystems and elements of the water supply system (WSS) in order to improve its reliability has been analysed. It is common that during WSS functioning various undesirable events (failures) may occur. They can cause losses of water, breaks in water supply and secondary water contamination in water-pipe network, which might seriously threaten consumers’ safety or even their lives. The main purpose of the work was to present new methods of the water supply system operation and safety reliability management utilizing information techniques. The paper also describes the modernization of an existing WSS in order to improve its functioning in terms of technical, economic and reliability aspects.
