The development offers all the editing, analysis and results presentation that characterize GIS.Within its potentials, one can find the customized tools for the work on the aqueductinfrastructure (Figure 1), with the purpose of demarcating failures or scheduled shut downs, areasaffected by the lack of water, connections to the network’s mathematical models, studies of waterlosses, direct ties with the users and follow-ups during the maintenance periods. Likewise, it hasspecific developments for the management and assessment of the sewerage network, as well asfor the elaboration of new supply, sewerage, and rainwater drainage projects.The use of geographical locations is an important function used by the system to defineexploitation parameters. The multi-user editing on the Data Base makes the system provide fastinstruments for constant update. GisAgua can be the entrance and exit point for an importantnumber of computer applications of general use in a water supply company.The project GisAgua-Aguasde La Habana has become anessential tool for thedevelopment of the hydraulicand sewerage infrastructureof the capital city. It isconsidered to be of a greatuse for the planning andstrategies in a short,medium, and long-term, dueto its ability to generatemulti-criteria studies withgeographically referencedcomponents. It has become aconnection interface withentrance and exit points forthe company’s diversecontrol, management andoperation computer systems.The tool goes beyond theborders of Aguas de LaHabana by becoming anessential information sourcefor urban growth andterritorial organizationprojects, and studies onrational and productive useof water. The aforementionedproject has laid thefoundations for thedevelopment of water andsewerage informationsystems in Cuba byestablishing the needs for itsefficient development.
