Resumo
Due to the numerous cases of population supply problems due to low water availability, this subject has become one of the references for the management of water. The lack of studies directed at settlement communities makes this management difficult and the reality of the families is unknown. In order to determine the consumption and availability of surface and underground water and the respective specific flow rates in settlements in the state of Goiás, settled communities from the Regional Superintendence 04 of the National Institute for Colonization and Agrarian Reform (INCRA) were selected. The aquifers and study basins were identified according to the location of 62 communities. Through data analysis and methodological application it was possible to obtain estimates of water availability for each community, using the parameters of reference flow rate in 95% of the time (Q95) and exploitable volumes of groundwater and deep aquifers, thus making it possible to calculate the specific flow rates for each resource analyzed. The demands for consumption and for the development of activities were stipulated in order to establish correlation with the results found. It was observed that with regard to surface resources the demands can be met in 64.52% of the settlements, as for the underground resources this index remained at 100% for deep aquifers and 80% for groundwater aquifers. This demonstrates the importance of knowledge regarding the use of resources for the supply of each family and that allows each of these communities to understand the water situation and promote the management of these water resources.
