Los Arenales aquifer is a sandy groundwater store over 7,500 square kilometres located in the Autonomous Region of Castilla y Leon, Spain. Since the mid-20th century, the expansion of irrigation has led to a decline in groundwater level of more than 20 meters. This Aeolian sand aquifer, with basins up to 55 metres thick, is also very vulnerable to drought. In order to mitigate this impact, the Spanish Ministry of Agriculture developed Managed Aquifer Recharge (MAR) facilities in three pilot zones. The project, building works, tracking and further monitoring was entrusted to Tragsa Group, a MARSOL project partner.
After more than a decade of operation, MARSOL intends to provide technical solutions for MAR technology, in order to improve the facilities efficiency and nearing the MAR technique to agroindustry, the principal activity in this area.
