Abstract: Most of our earth surface is covered by water; however, less than 1% of total available water is fresh water which is mostly available in lakes, rivers and underground. Again, about one-third of that potential fresh water can only be used for human needs due to mixed factors. Approximately 1.1 billion people in this world have inadequate access to safe drinking water. There are 26 countries that do not have enough water to maintain agriculture and economic developments. At least 80% of arid and semiarid countries have serious periodic droughts. A third of Africans and most of Middle-East people live without enough water. This experiment was performed at the National Centre for Energy Research and Development, University of Nigeria, Nsukka.15 litres of salty water was poured inside the solar distillation basin with black surface absorber to enhance absorption of solar radiation. The experiment was monitor daily and appropriate quantity of water produced was recorded. The result gave maximum yield of 3.3 litres of distillate. The atmospheric temperature produced varied from 27°C to 31 °C. The bar chart represented 3 hourly production of distillate from day 1 to day 4.
