A desalination system includes an evaporation chamber 47 for receiving, via an inlet 2, water from a salt water source. The chamber comprises a basin for filling with water and a canopy 11 arranged over the basin and adapted to direct solar energy onto the water. The canopy includes a plurality of condensate channels 34 formed on the internal surface thereof, which direct the condensate to a collecting channel 8. An outlet 13 directs collected condensate from the collecting channel, suitably to a storage tank 14 accessible for the supply of potable water, e.g. for drinking, agricultural or horticultural uses. The canopy can comprise one or more Fresnel lens. An underground irrigation system is also claimed wherein a plurality of pipes 16-22 of generally reducing diameter are connected to the storage tank of the desalination system. A soil composition of biodegradable organic materials can be located above the pipes, wherein the soil is layered with sand to form a top soil. A mesh blanket and a sand dune can be employed to prevent movement of sand particles by the wind. The irrigation system can be suitable for greening hot arid and semi-arid regions of the world. |
