Abstract-In the 1970s, São Paulo State defined qualitative frameworks for its water resources based on main economic activities to be developed on rivers basins. Sometimes objectives are too far from the actual moment, and that temporal dimension horizons can be better defined on participative and technical basis. Actually is being studied a criteria to subsidize delimitation of intermediary objectives that supports the planning process to be continuously developed on a more intensive progressive perspective. Once the planning have being elaborated on a participative foundation among municipalities, State government and society, a criteria approved by the stakeholders can help on reducing the natural conflicts when stablishing planning products. The proposal presented in the actual paper was approved preliminarily and is submitted to further studies actually.

The need to control pollution is a relevant environmental issue in Brazil, and in the world. Population growth demands a greater exploitation of natural resources, in many cases, above the natural recovery capacity of ecosystems. The decontamination of a river or lake involves, among other forms of intervention, the management of sanitation services, thus allowing the qualitative improvement of water resources. The progressivity of the supply of sanitation infrastructure will allow the attendance of the regular areas with collection and treatment of sewage. On the other hand, in order to achieve their goals, it is also necessary to address the social issue, the precarious housing, and especially the irregularly settled ones, which demand greater efforts to provide sanitation services.
