For the adequate development of the cities, it is necessary: qualification of the professionals of the cities better to manage the problems existing; creation of state programs of support federal to take care of to the necessities of the cities in the advising and the incentive of preventive programs of planning; development of programs directed toward the financing of sanitary systems and flood control for the cities. the main one: to have more investment and in correct way in systems of basic sanitation. CONCLUSION Under supplying aspects, the lack problems d' water that occurs currently in the world, and especially in Brazil, results of low the efficiency in supply and great volumes of losses, over all in aduo. However, valley to stand out that the integrated management of waters must be carried through under sistmica vision, involving the water that flows off visible for the rivers; the water that infiltrates in lands and of the support to the development of its vegetal or cultivated covering; the water that infiltrates and circulates for the subsoil of the hidrogrfica basin in I appraise and that it goes to empty in the rivers during the periods without rains, feeding its discharges of base; the rain water caught for the watering holes and I reuse of the water in cities, in the industries and agriculture (Rebouas, 2004). Unhappyly, it is not this model of management that if practises in Brazil, where domestic sewers contaminate the river to the sum of the captation for supplying. , In a similar way little recommendable it is the water captation of wells, of over all low depth, in populated areas where it does not have net and treatment for domestic sewers and these infiltrate contaminating the ground and the underground water. In fact, the concepts of integrated management also presented are transgressed in diverse situations inside and outside of the country, as in the case presented on the Great So Paulo, where sources receive pollution for domestic sewers. .
