The topic of Global Agenda 21 related to drinking water supply and sanitation was necessary and adequate to the Brazilian reality and a challenge that should be faced in 1992 by the country and the government. Thus, based in 1992 information existing, it is clear the great importance of the execution and implementation of actions related to water supply and sanitation in the day to day investment and planning following Brazilian Agenda 21.
Which is observed on the evolution historic of sanitation activities between 1992 and 2015 is that despite the total amount of investment have increased steadily over the years, inequality of sanitation and water supply conditions between regions remains uneven, as identified in 1992. Since the signing of the Brazilian Agenda 21, the evolution in the legal and institutional framework, as well as new ways of planning and diagnosis of the real situation of sanitation services (including intermittent data, for example), has contributed not only to be known to real situation of sanitation in Brazil, but also as tools to be made better investments. However, the need for investments in the implementation, expansion and maintenance of water and sewage infrastructure in Brazil is significant and urgent: the deficit and inequalities between regions are large and need to be overcome. Although the data show wide necessity of structural measures, it is noteworthy that the non-structural measures, i.e. those whose purpose is to provide management and administrative support in the provision of services, must also be applied to ensure the sustainability of services and their organization.
About rural sanitation, it is clear that the desired Agenda 21 Global and its correspondent in Brazil in 1992 is still far from being met. Few programs for rural sanitation, although the experience of Integrated System of Rural Sanitation (SISAR) has been successful. The National Basic Sanitation Plan (PLANSAB) brings a specific program for basic sanitation for rural communities and traditional population, but the National Rural Sanitation Program began only in September 2015.
It is also noted that the goals set in PLANSAB are important to expand and provide quality sanitation services, as well as being the basis to monitor and supervise the implementation of the proposed works, projects and programs. However, it is not possible to follow the evolution of the indicators, as a new and updated national sanitation research has not yet been released, so it is still not possible to say whether the planned actions are applied in fact.
Finally, the Brazilian Agenda 21, on the topic of sanitation and water supply, has been developing and evolving since 1992. This development occurred not only in terms of service and quality, but also from an institutional point of view, although more investment is needed to achieve the universalization and equity of services in quantity and quality for all, in all regions.
