A solar driven irrigation apparatus for converting contaminated water contained in a contaminated water body into distilled water and using said distilled water for irrigating vegetation grown on the said irrigation apparatus, the solar driven irrigation apparatus comprising a cover in the form of a geometrical projection, being a dome extending along a vertical axis from a bottom end to a top end, the bottom end being in contact with contaminated water body when the apparatus is in operation; the cover comprising a wall, an opening, a semi-permeable mesh, a floatable base for supporting and enabling the cover to float over the surface of the contaminated water body, soil layer and a chamber, wherein: the wall, made of a transparent material, is adapted to be in thermal communication with the external environment for capturing solar heat and in optical communication with the opening for allowing passage of solar rays from the external environment to the opening; the semi-permeable mesh, which itself supports the soil layer and the vegetation to be irrigated, is located along the top of the wall, the chamber is the internal space of the geometrical projection located between the wall, the semi-permeable mesh and the opening; the chamber being adapted to be in fluid communication with the opening for receiving vapor formed and allowing the vapor to pass through the semi permeable mesh into the soil layer, which condenses said vapor forming distilled irrigation water; the opening is adapted to be in optical communication with the wall and the surface of the contaminated water body for allowing passage of the solar rays from the wall to the surface of the contaminated water body for heating the contaminated water to form a vapor, and adapted to be in fluid communication with the surface of the contaminated water body and the chamber for allowing passage of the vapor from the surface of the contaminated water body inside the chamber. the wall, made of a transparent material, is adapted to be in thermal communication with the external environment for capturing solar heat and in optical communication with the opening for allowing passage of solar rays from the external environment to the opening; the semi-permeable mesh, which itself supports the soil layer and the vegetation to be irrigated, is located along the top of the wall, the chamber is the internal space of the geometrical projection located between the wall, the semi-permeable mesh and the opening; the chamber being adapted to be in fluid communication with the opening for receiving vapor formed and allowing the vapor to pass through the semi permeable mesh into the soil layer, which condenses said vapor forming distilled irrigation water; the opening is adapted to be in optical communication with the wall and the surface of the contaminated water body for allowing passage of the solar rays from the wall to the surface of the contaminated water body for heating the contaminated water to form a vapor, and adapted to be in fluid communication with the surface of the contaminated water body and the chamber for allowing passage of the vapor from the surface of the contaminated water body inside the chamber.
