Abstract/Summary Mine sites manage releases of water to ensure compliance with regulation of the use of water resources and the protection of surrounding environment. License conditions restrict discharge to downstream watercourses to specific conditions of flow and concentration to minimise impacts on receiving waters. Traditionally, mine sites comply with discharge restrictions by undertaking detailed hydrological analyses of relevant catchments. Such studies can predict which rainfall event may lead to non-compliance. The underlying assumption is that the only factors that can influence the discharge risk are rainfall and runoff. However, a mine water system is not limited to its catchment. It also comprises additional inputs and outputs, stores and tasks, such as ore processing and dust suppression. These connected elements constitute a complex system with feedbacks, so that a perturbation in the water system leads to changes in the water balance status. We demonstrate that a systems modelling approach can be used to design a site water management system that balances the dual risks of discharge and running out of water. The approach has been applied to a range of mining operations resulting in the capacity to understand the implications of wide spread implementation of leading practice water use and loss rates.
