A solar still system for converting contaminated water contained in a contaminated water body into distillate water, the contaminated water body having a water surface, the solar still system comprising:
- a cover in the form of a geometrical projection comprising a wall, an opening and a chamber, 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 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 vapour, and adapted to be in fluid communication with the surface of the contaminated water body and the chamber for allowing passage of the vapour from the surface of the contaminated water body inside the chamber;
- and
- the chamber is defined by the wall, the chamber being adapted to be in fluid communication with the opening for receiving the vapour formed and condensing said vapour at the internal surface of the chamber wall for forming condensed distillate water therefrom,
- wherein the geometrical projection form of the cover is a dome extending along a vertical axis from a bottom end to a top end, the bottom end being in contact with the contaminated water body when the solar still system is in operation, and wherein a conduit in fluid communication with a condensed water collector is used for directing the condensed distillate water outside the chamber;
- a water transportation apparatus comprising:
- evaporation zones for converting water into water vapour;
- condensation zones for condensing the water vapour into condensed water, the condensation zones being in fluid communication with the evaporation zones;
- water vapour conduits adapted to enable the fluid communication of the water vapour between the evaporation zones and the condensation zones, wherein said water vapor conduits extend along a vertical axis that is perpendicular to a sea level axis;
- condensed water conduits adapted to enable the fluid communication of condensed water between the condensation zones and the evaporation zones;
- wherein the evaporation zones and the condensation zones alternate in position along a water transportation path between a water source site and a water destination site for enabling the transport of the condensed distillate water from the water source site to the water destination site through alternating processes of evaporation-condensation and condensation-evaporation of the water, wherein the water source site is off-shore and the water destination site is a land reservoir, and
- wherein a series of evaporation and condensation processes in the evaporation zones and the condensation zones lead to an overall transport of water from the water source site to the water destination site along the water transportation path.
