Full Description

The reclaimed water system of the City of Tucson, Arizona currently serves 250customers with a total 1999 annual demand of 9,300 acre-feet. The reclaimed waterdistribution system, with 85 miles of pipeline, serves an area of approximately400 square miles. Reclaimed water is used for turf and landscape irrigation atgolf courses, schools, parks, street medians, limited agricultural uses, commonareas of commercial and multi-family residential complexes, and some singlefamily homes. This paper discusses how a Geographical Information System (GIS)database was developed and utilized to efficiently identify and prioritizepotential reclaimed water customers. Initially, a comprehensive search of a 1,200square-mile study area identified all potential customers. The search wasaccomplished by querying Pima County (the county in which Tucson is located)databases to locate land parcels with uses generally associated with turfirrigation, such as golf courses, parks, schools, agriculture, hotels/resorts,cemeteries, and uses with large common areas, such as commercial and multi-familyresidential. The search identified nearly 1,500 potential new customers with anestimated annual demand of 33,000 acre-feet. The GIS database was then used toassess the geographical distribution of demands and demand densities in order toprioritize areas for system improvements and service expansion. Finally, thedatabase was utilized to prioritize areas for potential infill of the existingreclaimed distribution system. Information presented in this paper will behelpful to communities that wish to identify potential customers within a largeplanning area, and to establish a database that can be utilized to plan systemexpansions and to market their reclaimed water programs.
