Abstract: The high economic and environmental costs of large water supply projects are forcing engineers to consider not only alternative means of increasing system reliability, such as interconnections, water reuse, and demand management, but also the option of accepting a lower standard of reliability. There is a need for improved computer-based methods for estimating and optimizing the reliability of bulk water supply and transmission for public water systems while considering all significant sources of supply unreliability. The purpose of this paper is to survey the application of reliability models to bulk water supply systems and to highlight some promising new approaches.
