In 2007, the Federal Law 11.445 created the National Policy for Basic Sanitation - NPBS, which established national guidelines for basic sanitation services. In 2010, the Federal Law no. 12.305, which established the National Policy for Solid Waste - NPSW, came into force. However, many are the obstacles faced by municipalities so that the NPSW can, in fact, be put into practice. Besides the presence of active or deactivated dumps - and, in this second situation, those without environmental recovery works - there is a lack of regularity in the collection, lack of vehicles and specific machinery, among several other problems. The territorial governance model proposed in the research seeks to point out the relevance of sharing the protagonism of public management - instead of an exclusively state management - with other two segments, in order to create an environment oriented to an effective management. In this new perspective, management, in line with the legislation, would also guarantee the financial autonomy of management, thus relieving the municipal budgets. Therefore, it is considered, for these reasons, the need for a territorial governance capable of establishing rules for cooperation and intersectoral co-participation in the territory of the Iguaçu river basin in Rio de Janeiro. It is believed that this model is at a higher level among others that instrumentalize the provision of services to the population, since, through it, the participants, with strengthened autonomy, agree on the rules that they will follow, as a way to enable the effective provision of public services. Therefore, the democratic sharing between the state agency, organized civil society and the business sector - in the actions, targets and in the mobilization of resources for the management of urban solid waste, in its planning, execution and assessment stages - is considered a vital transition to be put into practice.
