Abstract: Procedures for projecting future water needs have ignored the spatial distribution of consumers. However, with a GIS approach to water demand forecasting and supply planning the spatial dimension of M&I water uses can be modeled. Using the map overlay capability of GIS to represent the geographic variation of parameters which explain the water demand of consumers, spatially disaggregated water demands are computed for water system service areas. Supplies available to the service area are maintained in a data base and allocated to satisfy the demands. The GIS model is now operational for Utah's Wasatch Front, the most rapidly growing urban region of the State.
