Abstract

The water mains burst in Seoul, Korea is one of the most frequently raised water management problems and the major reason can be found in the inefficiency in design and management of the network. The study developed a prototype system that allows the user to evaluate the level of deterioration and to design alternative water mains for simulation. The study suggests an evaluation scheme that models mains failure based on different variables such as pipe age, diameter, ground elevation, and pipe materials. Also, the user can interact with the system to create virtual pipelines that link the user-provided origin and destination points considering the efficiency in regional supply, distance, road network and construction cost. A shortest path algorithm called Dijkstra's algorithm was used for the pipeline simulation. The data was constructed using the GIS based on the residential blocks which are defined by supply region, water demand and street network. The system was applied to a test region in Seoul, Korea.
