The management of water loss in historically grown drinking water networks is a major challenge for water supply utilities. According to the state of the art, the sectorization of the distribution network into measurement zones is an efficient method of water loss management. Such zoning is to be planned in a targeted manner in order to maintain the desired meshing and consequently the redundancy of the system in the best possible way but still generate measuring zones that enable a fast detection of new leaks to be recognized quickly. In addition, dividing the network into zones enables an assessment of the amount of water loss (water balance) in theses zones and thus a better identification of problematic sub-areas. This also serves as support for the renewal planning. Hence the major task in this project is to develop and apply a proper sectorization algorithm for the water distribution system of the city of Graz.
