Clara Pur (CP) produces drinking water by means of solar sea water purification.

Solar thermal energy is used to make drinking water out of: saltwater, untreated, ground- and surface water. Sustainable self-supply with drinking water for housing estates, hotels, villages and business establishments in regions with water scarcity, but with an abundance of sunshine is supplied thanks to CP. Arsenic/inorganic arsenic that is naturally present at high levels in the groundwater of a number of countries is removed. CP produces drinking water at the point of use, which solves the distribution problem : in many cases water must be transported, by ship or by truck but can not be consumed immediately after transport, it must be treated. CP approaches two basic problems in the supply of drinking water: water treatment and distribution of clean water.
