The invention refers to a device for extracting condensation water by heating and cooling respectively of a transport medium (3) flowing in a pipe drawing (5,6). Said device consists of at least one pipe circulation circuit (4) comprising said pipe drawing (5,6), which alternating extends a first predetermined distance just under a ground level (7) constituting a heating level (8) and a second predetermined distance very much under said ground level (7) constituting a cooling level (9), said circuit (4) having at least two end portions (10,11) where the pipe drawing (5,6) having a 180° bending and between these crossing locations (12) of said pipe drawing (5,6) where it alternates from its upper extension in the heating level (8) to its deeper extension in the cooling level (9), the pipe or pipes of the pipe drawing (5,6) being in the heating level (8) or nearest the ground level (7) extract a condensation on its mantle surface (13) and are either intended to directly wet surrounding sand or ground (14) or comprise at least one condensation collector (15) enclosing around actual pipe sections for collecting the condensation water (2), which later on can be collected for drinking water or for watering objects.La présente invention concerne un dispositif pour extraire de leau de condensation par chauffage et refroidissement, respectivement, dun matériau de transport (3) qui sécoule dans une extension de tuyau (5, 6). Ledit dispositif est constitué dau moins un circuit de circulation à tuyau (4) qui comprend ladite extension de tuyau (5, 6), qui sétend en alternance sur une première distance prédéterminée juste en dessous dun niveau de sol (7), qui constitue un niveau de chauffage (8), et sur une seconde distance prédéterminée plus en dessous dudit niveau de sol (7), qui constitue un niveau de refroidissement (9), ledit circuit (4) comportant au moins deux parties dextrémité (10, 11) où lextension de tuyau (5, 6) présente un coude de 180 ° et, à des emplacements de cro
