This article is a historical review of the events that occurred in the exploitation of the La Yarada coastal aquifer, located in an arid zone, located at the head of the Atacama Desert. The period in which exploitation has been in a balanced regime (recharge-ex-tractions) until the 70s and unbalanced since the 80s has been identified. It also identifies favorable and unfavorable management measures in the conservation of the aquifer system. Engineering measures were identified in the future, leading to the recovery and conservation of the aquifer, which consist of the incorporation of hydraulic barriers.
