Abstract: Pure and distilled water is now serving as a basic daily necessity for human being functionality. Solar energy is widely being used for purifying the salt water with basic fundamental of evaporation and condensation through a solar still which captures the sunrays, evaporates the seawater, condensate the vapors and purifies the water. This method is the widely used green method for water distillation via set ups. This paper concentrates at water purification by modified stepped solar still with wire mesh and comparing it with a conventional still. Still with 4 steps with depth of 5 mm and 120 mm wide were fabricated on modified still. The efficiency of stepped stiller was altered up to 30.72%and the amount of distillate obtained was 1932 ml/m2 /day in case of conventional distillerand 2800 ml/m2 /day was for stepped one.
