Abstract for: A System Dynamics Model for Integrated Water Infrastructure Asset Management

This paper presents the development of a system dynamics model as a decision support tool for the integrated asset management of water distribution and wastewater collection systems. The proposed system dynamics model integrates physical infrastructure with finance and consumer sectors, and enables user rate-setting and planning of integrated water infrastructure operational and capital works over the life-cycle of the infrastructure (10 to 100 year planning horizon). In practice, the proposed decision support tool helps water utilities to evaluate various management strategies for meeting infrastructure service and financial performance indicators, comply with legislations, and make optimized asset management decisions.
