Procedure for evacuation of groundwater, characterized by the perforation of the ground at a point where there is an underground liquid vein to reach it, placing inside the perforation an open tube or boiler and inside it a tube also open, isolating the inside of the boiler by means of placing a surface concrete bench between it and the ground and a cover between the boiler and the inner tube; a valve is installed in the lid between the boiler and the inner tube, which allows the introduction of pressurized air in an amount such that it is able to overcome the pressure due to the height of the water column between the interior level reached and the outside exit through the central tube, whereby the water leaves the end of said central tube spontaneously and in a continuous manner, by the pressure of the interior air that becomes permanent by closing the valve that served for its introduction.
