The invention refers to a device and a process for extracting water from the environment. The device comprises a means for capturing water from the environment by means of a liquid desiccant, an extraction chamber, a first duct through which liquid desiccant with water flows from the capture means to the extraction chamber, a second duct through which liquid desiccant flows from the extraction chamber to the capture means, a reservoir for depositing extracted water, a third duct through which water flows from the extraction chamber to the reservoir, a vacuum generator whose suction point and discharge point are operationally connected to the reservoir in order to suction the gas present in the reservoir and transfer gas into the reservoir, and a control device that controls the vacuum generator. The operation of the vacuum generator creates a pressure and temperature gradient that leads to evaporation of the water in the extraction chamber.
