The first hydrogeological investigation for the definition of the Carracillo aquifer (Segovia) was carried out in order to plan the best possible artificial recharge works provided for within the framework of the Royal Decree-Law 9/1998 “El Carracillo Aquifer Recharge. Intake and Pipeline Work, Infiltration and Irrigation Adequacy (Segovia). These studies revealed the existence of two regions hydrogeologically favourable for water storage from flows derived from the river Cega: the first known as the paleo-landform site located within the irrigation area, and the second area called the storage area located in the eastern sector of the district.
In order to exactly estimate the minimum and maximum volume of water that has to be managed in the paleo-landform site over a period of five years, the Tragsa Group has carried out, at the request of the Ministry of Agriculture Fisheries and Food, some of the hydrogeological work, which included the exhaustive follow up of the piezometric behaviour of the aquifer and the detailed analysis of each of the external actions that have a direct influence upon it, such as the useful rain, the artificial recharge, the extraction by pumping, and the overland flow, amongst others.
