摘要：The worldwide production of potable water represents a without cease enormous challenge. Each year 80 million new persons seek their rights for aqueous resources over the earth surface. Unhappily almost three billion new inhabitants for the next fifty years will be born in lands where scarcity of water is already nowadays present. Brazilians seem not worried with their water reserves forgetting that one deal with a renewable but not inexhaustible wealth. As the administration of urban occupation process reveals its inadequacy in terms of capacity to face water provision in a situation of demand bigger than supply, it is noticeable the conflict between the concessionary company, the municipal public government and citizens of the community, reaching to a point of real degradation of urban, environmental, social, sanitary and economic conditions which culminate in an urban catastrophe. Adding problem is the exodus from rural communities and from big cities whose inhabitants search for better life conditions in smaller urban centres. Water is becoming an expensive wealth. The general objective of the research is to prove the necessity of adoption of a model to support the administration of the urban occupation process, concerning the capacity of the water supply system. Florianopolis attract in the last decade significant number of new inhabitants. With the preconceived idea of establishing as area of study one that could be evaluated through daily water measurements of macro-meters, the elected area was the District of Santo Antonio de Lisboa. The application of linear regression statistical method demonstrates significant correlation between data obtained from the studied area and the ones from Ponta do Sambaqui neighbourhood (pilot area). Thematic maps directed to Ponta do Sambaqui, dealing with number of days that each residence suffered lack of water and number of days of water rationing per habitation, demonstrate de necessity of adoption of the urban management model proposed. Ultimately, the inconvenience of lack of tradition, which leads to, the non-use of topographic maps by de concessionary company, was demonstrated. As consequence of what one would expect from results, other secondary propositions were made, i.e. the direct participation of the inhabitants in the urban management process concerning the water supply system and the permanent concourse of the universities in the evaluation and solution of problems of such importance
