The safety of water supply system (WSS) functioning should be examined interdisciplinary in the scope of drinking water health as well as quality and quantity of natural water resources. There are three basic safety barriers of water supply system: prevention, security and counteraction. These barriers make serial structure and reduce the risk associated with public water pipe. Compensation and reduction methodology of integrated risk in the safety-health-environment system has been presented. Based on this, the basic rules of critical management have been formulated to the effect of stocks and society preparation for the case of undesirable event occurrence which caused threat to life, restore, environment and infrastructure. ...
