The access to environmental sanitation services, especially the collection and final disposition of solid residues, is fundamental for the public health and environment preservation, because by reducing the bad garbage disposition, there is a decrease of the endemic diseases and soil contamination. The investment in environmental sanitation is one of the great challenges for public managers, due to its wide relationship among the environment, public health, and local development. The present work sought to esteem the willingness to pay for the garbage collection service for the municipal district of Palmas, in Tocantins, through the contingent evaluation method. The obtained results indicate that the main decisive factors of the willingness to pay are: the level of income and the education.
