Water supply system is complicated technical system which belongs to underground urban infrastructure. Its accurate functioning determines everyday live stabi lity of citizens. Risk analysis is a key phase of t he process of water supply safety management. The aim of this paper is to present new propose of methods for risk of the first type (associated with quantity of supplied wa ter) and the risk of the second type (associated wi th quality of supplied water) analyses in water supply system. Th e paper contains the description of matrix methods for risk analyses and methods describing cause-and-effect re lationship of failure events (fault tree analysis).
