For financial and organisational reasons, these water resources plans are progressively being implemented, with priority given to scenarios that consolidate the local structure. Prior to the implementation of the federal government’s public policies for the construction of water and sanitation utilities at national level, inter-institutional collaborative agreements became official between the federal public administration’s departments and institutions. Human, financial, infrastructural and technical resources were coordinated through these agreements in order to develop studies and projects, and implement basic infrastructures and utilities in low human development indicator municipalities.
