Abstract In the last decade, The Araucanía region has presented water scarcity, which is manifested critically in the summer months. At the present, structures that allow water storage in a sustainable way are needed, that generate a low impact on the environment and allow the preservation of underground resources for next generations, within the framework of this need, the application of a water accumulation system type DBI (low impact development) was carried out, with glaciofluvial soils present in the Region. To verify this accumulation system, different layers of glaciofluvial soils were classified, using granulometry and Atterberg boundaries. Once the soils that formed these strata were known, a stratigraphic profile was postulated that positioned the different layers strategically to allow the storage of rainwater. Later, the stratigraphic profile was tested, through an analogous aquifer model, which consisted of a system that allowed measuring the amount of water entering and leaving the stratigraphic profile. This model considered the scaling of granulometry and thicknesses and data of frequency, intensity, and percentage of infiltration of rainfall. Finally, it is recognized that the system is capable of storing water but must undergo adjustments to increase its efficiency. The system has high porosity values, varied values of permeability and transmissivity, therefore it is demonstrated if the location of the different layers of glaciofluvial soils changes, the general properties of an aquifer will change, being able to store water, however, the transmission of water obtained in the analogous model is very high, water it is transmitted in a short time, this model must be improved by the study of low permeability soils with compaction and permeability studies.
