Water distribution networks are complex systems whose task is to deliver to the consumer a sufficient amount of water, of satisfactory quality. Reliability analysis of the operation is an important issue in the planning of further development and maintenance of the existing system. Reliability is considered from multiple standpoints, because besides a task to supply consumers, this domain includes the protection of consumers from potential danger. In this context it is necessary to consider isolation valve system installed in the distribution network whose mission is to exclude certain parts of the network. Segments of the distribution network are defined as parts of the network that can be isolated from the rest by closure of certain isolation valves. As water distribution systems have complex structures, it is necessary to apply the algorithm for defining segments. Presented algorithm has the task to, using the hydraulic models of water networks entered via standard software (EPANET,... 3Dnet ), define the network segments, accidental disconnection of the network as a result of the isolation of a segment, as well as a shortfall in water supply. Topological incidence matrices are utilized, which are used also in hydraulic models of water supply networks. Methodology used for segmentation is described through a simple example.
