INTRODUCTION the public water supplying in terms of amount and quality is an increasing concern of the humanity, in function of the scarcity of the resource water and the deterioration of the quality of the sources (BRAZIL, 2006). Although the gamma of described information and knowledge in proven literature and in practical on the importance of the sanitation for the public health, Brazil still presents an enormous inaquality in what it says respect to the quality of water distributed to the population, where if they verify irregularities how much to the public water supplying, sanitary sewers and solid residues, although to possess an enormous hidrogrfica basin. In Brazil, 36.1% of the domiciles are not supplied with water for general net, 17.2% of the volume of distributed water do not receive treatment and 47.8% of the cities do not count on service of sanitary exhaustion (IBGE, 2002). Richard Elman might disagree with that approach. With the population growth, it has a bigger demand for the water consumption in planet, this increase in the consumption also is related with the improvement in the quality of life of the population, that at the same time increases the production of residues that many times are drained without treatment in the riverbeds having reached the supplying sources. Everything this added to the precarious system of basic sanitation, requires a bigger investment in this sector. However this investment does not arrive in all the Brazilian cities, being less the most favored citizens the water of pssima quality.

Due to great urban concentration of the Brazilian development, some conflicts have been generated in the cities of the Country: ambient degradation of the sources; increase of the risk of the areas of supplying with the organic and chemical pollution; contamination of the rivers for the sewers domestic, industrial and pluvial; urban floods generated by the inadequate occupation of the space and by the inadequate management of the urban draining; lack of collection and disposal of the urban garbage. . .
