The Potchefstroom Campus of the North West University contains old water pipelines that are not well documented. Many of the newer water pipelines are not well documented either. A central data storage system that could contain the information with ease of access to update and retrieve information of these waterlines is lacking. There is a need to find a way that existing potable water network data could be represented and stored with GIS. The solution would contribute to the management of the water system on Campus. The aim of this study is to create a seamless geodatabase as a pilot project for the potable water infrastructure at the Potchefstroom Campus of the North West University. The pilot project focuses on buildings E4 and E6. ArcGIS 10 was selected to serve as the key software system that would be applied as a medium to solve and represent the problem. ArcGIS geodatabase serves as a container to store spatial data with. Data with regard to the potable water system was collected from various sources of which available electronic and hard copy CAD data was the general format. A file geodatabase was created in ArcCatalog with a standard co-ordinate system as reference to the data. ArcMap was applied for 2D editing and georeferencing of the CAD drawings which were followed by a composition of attribute data for the created features. The end result was represented in ArcScene for 3D visualization and 3D analysis. It also provided ease of access to the attribute information and relationships and the capability to perform the shortest route analysis.
