The use of GIS (Geographic Information Systems) has been widely used for urban waters management. One step in the development of this field has been to use GIS information not just for mapping and consulting, but also to analyze trends and make decisions by means of the applications provided by spatial analysis. Spatial analysis in GIS comprises a group of procedures used to carry out the study of the territorial structures and relations based on the knowledge about the position and features of the geographic entities resulting from the variables involved. This paper proposes its implementation for the processes of planning and decision making within a water supply company, which is illustrated by practical cases with real data. [ABSTRACT FROM AUTHOR]

Companies devoted to water supply and sewerage service activities usually have a series of drawbacks such as the poor system knowledge due to lack of data about networks and low trustability of the existing information, as well as the poor usage of tools to improve management. It is compulsory to stop deterioration of these systems so as to make them more efficient. The most effective means to achieve that goal is by using tools like geographic information systems (GIS). In this paper, the authors carry out an analysis of the use of GIS in water management companies. They explain GIS design as applied in Aguas de la Habana enterprise, as well as its links with other technologies that can be applied to any other water supply and sewerage company.
