Generally, the root cause of these problems if it finds in the related institucional aspects with the management of the hdricos resources and the urban environment. This process occurs, mainly, because the cities had not developed institucional and economic capacity to manage the problem, whereas States and Union meet distant of the reality of the problem, what it makes it difficult to implement adequate a managemental solution (Tucci, 2001). In this in case that, the damages for society are significant and the legacy for the future generations associate to the lack of investment in the solution of these problems could be the return the unsatisfactory social pointers of the last decades. This work has as objective to point out the current situation of the public system of water distribution in Brazil. WATER DISTRIBUTION TREATED IN BRAZIL IN CURRENT DAYS Brazil presents an enormous diverse water potential candy for use, since the domestic consumption until the use in agriculture, however, this wealth of natural resources is being affected in some regions of the country. The processes of urbanization, industrialization and agricultural production have not taken in account the capacity of support of ecosystems (Rebouas, 1997 apud Brazil 2006). The majority of the rivers that cross the Brazilian cities is spoiled, being this considered the biggest Brazilian ambient problem. This deterioration occurs because the majority of the Brazilian cities does not possess collection and treatment of domestic sewers, playing in natura the sewer in the rivers. When net exists, does not have station of treatment of sewers, what it comes to still more aggravate the conditions of the rivers, therefore concentrates the load in a section. In some situations, the station is constructed, but the net does not collect the volume projected because a great number of clandestine linkings of sewer in the pluvial system exists, that of separate sewer passes the compound (Tucci, 2001).
