ABSTRACT
The interconnection of themes such as environment, health and sanitation are increasingly central to society. The concerns arise from the irresponsible form of human relations established with the environment, characterized by the excessive and inconsequential way of using the goods of nature. Such conduct has had unpredictable environmental impacts, which, in most cases, go beyond the borders between national states. In this context, transboundary river basins are characterized by comprising two or more States, constituting a defined area for planning, management, cooperation in the field of sanitation. The study aimed to raise the debate on topics such as sanitation and environmental health in transboundary watersheds. In methodological terms, the bibliographic review and the documentary study were chosen, having as object of analysis the Brazil-Uruguay Treaty of the Mirim-São Gonçalo Hydrographic Basin. The results point to the need to expand knowledge about management instruments in transboundary watersheds. The institutional socio-political articulation between the actors must be intensified, with an emphasis on cross-border coverage, allowing the adoption of integrated basin plans, as well as action strategies in different demands, settling conflicts and generating a scenario of reciprocity, appreciation of citizenship and environmental sustainability.
