摘要

During the period of the structural changes in the processes of the European integration and regionalisation, the issue of the water services quality standards, which is associated with the social, economic and demographic development of the country, becomes more and more important. A properly functioning collective water supply system (CWSS) should ensure a continuous water supply to the recipients, with a suitable quality and adequate quantity (required pressure), at a specific time. These parameters must be maintained at the required level, which in reality is not so simple. Also indicators used for assess water services reliability for recipients are proposed. These indicators clearly evaluates the consequences of failures and at the same time retains the simplicity of estimation, which allows for its widespread usage in risk management.
