The implementation of programs like One Million Cisterns (P1MC), One Land Two Waters (P1+2) and the Fresh Water Program (PAD) are examples of actions for living with the semi-arid region that guarantee that rural populations have access to drinking water. In this sense, there is a need to understand how small municipalities with less than five thousand inhabitants are being supported by the coexistence programs created by the government to serve the population of these municipalities. The objective of this study was to evaluate the difficulties of access to drinking water in the 68 municipalities of the semi-arid region of Paraiba with less than 5,000 inhabitants. For this, the methodologies used were techniques of cross tabulation of data in a GIS environment of the information collected by the portals of the Ministry of Social Development and the Ministry of Environment about the programs in parallel with the SNIS data of the rural population supplied by general network of water. And it was found that there is vulnerability in water supply in these municipalities in the three programs presented.
