A solar driven irrigation apparatus (2) for converting contaminated water contained in a contaminated water body (60) into distilled water and using said distilled water for irrigating the vegetation (136) grown on the said irrigation apparatus the solar driven irrigation apparatus comprising a cover (8) in the form of a geometrical projection comprising a wall (12) an opening (16) a semi permeable mesh (132) a soil layer (134) and a chamber (20) wherein the wall 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 top of the wall is covered by a semi permeable mesh which itself support a soil layer and the vegetation to be irrigated 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 chamber is defined by the wall the chamber being adapted to be in fluid communication with the opening for receiving the vapor formed and allowing the vapor to pass through the semi permeable mesh located on the top of the wall such that said vapor passes through the soil layer thereby condensing said vapor for forming a distilled irrigation water.
