To be effective, a geographic information system must be created with its intended use, available source materials, and budget considerations in mind. Most utilities throughout the United States and abroad are planning or implementing an automated mapping–facilities management–geographic information system. The database acquisition and conversion process is typically the most expensive and time‐consuming part of implementing such a system. Many agencies convert water or sewer facility data immediately after a land and parcel database is developed. This article highlights the key technical issues associated with creating a geographic information system database to support water utility operations and applications. It describes database concepts and provides an overview of the data conversion process. Alternative approaches for developing a base map and converting water facility data are described, and technical issues relating to accuracy, symbology, feature content, conversion methodologies, and quality control are discussed.
