Analysis and evaluation of hazards in emergency situations in water supply systems

Abstract

The new regulation concerning the quality of drinking water offers a number of delegations on the waterworks inform users about the quality of tap water. The study analysis on the public risk health should be prepared. In the paper the analysis and assessment method of the population and property related to failure occurrence of collective water supply systems is presented. Four categories of factors having impact on the multiplicative risk: purity category or probability of danger occurrence, material damage, loss of population health and security were adopted. On this basis four-parametric risk matrix was developed. In the study also examples of application methods were presented. The method can provide a planning tool in crisis management at the local government level.
