ABSTRACT
This chapter reviews water-supply systems and components, aspects of their design, and GIS concepts and tools that support these activities. Potable-water and irrigation supply systems are shown to be similar in some respects, although potable supplies require a great degree of positive control over quality. GIS tools are applied for assessment and evaluation of supply-facility alternatives. Estimation of demand is a fundamental GIS task that drives capacity requirements. Pipe networks and canal distribution systems are seen to be basic networks for which sophisticated simulation and optimization algorithms are applied. Selected case studies are reviewed.
