Water supply systems and aquatic ecosystems belong unambiguously to the most vulnerable fields of national engineering infrastructure. It follows from risk analyses that they may be threatened considerably by action of natural influences and many anthropogenic events. Any threat or damage to the water management infrastructure always results in a decrease in housing standard, development of emergency regimes in health services, food production, accommodation services of towns and municipalities and simultaneously an impairment of fire security of built-up areas.
The subject evaluates, using the methods of risk analysis, the basic types of risks endangering aquatic ecosystems used for water supply systems, specifies emerging natural risks and anthropogenic hazards acting on water sources and production-technical facilities of public water supply systems. Based on the results of analyses, their comparison with development in the world and the use of new scientific knowledge of the given field, it makes the student familiar with the possibilities of real risk minimization.
