STORAGE OF PLUVIAL WATERS IN THE WATER TABLE AS A SOLUTION FOR WATER SHORTAGE IN THE BRAZILIAN NORTHEAST REGION
Given the percentage of available drinking water and population growth, if humanity does not change its habits, it may end in the coming decades. Despite the natural cycle of water, which causes this good not to run out, human interference can make it scarce. With this in mind, it becomes feasible to promote the recharge of the aquifer and to use the groundwater as a source of supply. The study presented below refers to a project that consists of facilitating the infiltration and storage during the rainy season of rainwater in the groundwater, so that they are returned to consumption in agriculture in times of water crisis, through wells. It was thought with emphasis for facilities where there is water shortage, that is, places where drought is prevalent for most of the year. The storage and use of groundwater in these regions brings many benefits, solving the problem of water scarcity, in addition to occur in a practical and inexpensive way, since the wells can draw water of any depth. For this, the study of the soil profile, through the standardized tests available, should be made to know its permeability characteristics, as well as the existence and height of the water table. It is essential that in the region the aid of a maintainer is used for the temporary storage of water precipitated on the surface, preventing it from flowing quickly and randomly.
