Abstract
The Geographical Information System is well suited as a tool for assisting with water supply problems. It not only carries out the inventory functions, as to what lies where, but assists with the manipulation of the data and the extraction of information for modelling and decision making. This section will describe the fundamental features of GIS directly relevant to water supply projects, and the ways that data are stored in a GIS. The Digital Elevation Model (DEM), which is of great importance to hydrology and water supply, will be considered in some detail. In terms of cost for implementing a GIS solution: manpower, data acquisition, software and hardware rank in about that order. Manpower is a very difficult aspect to specify for a project, so it will only be discussed briefly. Manpower depends as much on existing skills, training requirements and workloads for existing staff as on the GIS. The other three aspects are discussed with respect to the current state of the art; however technology is likely to change in the future.
