Flow pattern mapping of a water distribution network is important for operators and managers for its efficient operation, maintenance and management. Such a pattern can be developed for a water supply system from flow paths, which can be generated by travelling in the opposite direction of flow in the pipes from a demand (withdrawal) node to a supply (input) node in a pipe network. Similarly, the information about pipes forming primary loops is an essential part of the data for the analysis of a water distribution system. The loop data do not constitute information independent of the link-node information and theoretically it is possible to generate loop data from this information. Presented herein is an algorithm for flow paths generation and its application in flow pattern mapping and loop data formulation including identification of the water supply boundaries of each input point in a multi-input source water distribution system.
