In this paper, the causal feedback relationships among the components that make up the working mechanism of water supply systems management, including key factors and their relationship to the management of water pipes, were identified based on the conceptual framework established for water supply systems management. Subsequently, a system dynamics computer simulation model, which can be used to aid efficient management of water supply systems, was developed. The computer model consisted of water supply, pipe maintenance, and water supply business finance sub-models. The model was verified using historical data from a water supply service case study. Using the verified model, long-term managerial and operating conditions of the case study system were predicted under optimistic, basic, and pessimistic management condition scenarios. In addition, sensitivity analyses on major indicators of the case study system have been presented to show that the developed model can facilitate identification of the best policy for achieving a specific management objective of a water supply system.
