The Use of Geographic Information Systems (GIS) in Upgrading Water Distribution and Sewerage Systems

The creation and use of spatial databases for the management of public water/sewer utilities in order to be in alignment with the EC standards represent nowadays an important tool in making both their quantitative and qualitative exploitation as efficient as possible. Starting from this aspect, this paper presents the stages in the achievement of spatial databases compiled in a GIs application and an example of converting the specific data on IT support, the building of a relational database, the way the connection between the spatial data and the descriptive ones is achieved within the model. Once these connections are established, the information can be used in various types of analyses and optimization modalities in the water/sewer systems. The large volume of graphic information that can be acquired today imposes its use simultaneously with the necessity of ensuring centralized data control in the database management system.
