Abstract:The present article reports a comparison between two distinct regions of the country, understanding that Brazil is a continental country and that the condition of the northeastern semi-arid region is very peculiar in relation to the other regions such as Rio Grande do Sul. Data from the water storage policies of the Northeast and Southern regions of Brazil. In the case study in question, the results of the surveys showed that the maximum capacity of the basins that supply Caxias do Sul is 62,435,920.70m³ for a population of 435,564 inhabitants, while the municipalities of Icó and Orós are supplied by two reservoirs Which total 2.166.382.000m³ of capacity, supplying a population of 86,845 hab. Comparing the maximum amount of water per inhabitant, the following proportion is 24,945.39m³ / inhabitant in Ceará and 143.34m³ / inhabitant in Rio Grande do Sul. In this sense, it was verified the differences in the water resources management policies with Availability to the population. The main difference in the planning and management of water storage in the two regions is due to the long periods of drought in the Northeast region, while the rainfall in the South region occurs more regularly during the year, and there is a need to store a large amount of water For a period of time that may be several years.
