One of the essential needs of a living thing on earth is the pure water and nowadays this valuable natural resource is facing severe scarcity problems. Solar distillation is a better choice to minimize this problem by harvesting solar radiation in solar still and thereby producing pure water from hard water or brine. In this work, an attempt was made to enhance the productivity of still by flat plate collector, sponge, the combination. Finally, the productivity of the simple still was compared with that of a flat-plate collector, sponge, the combination. Use of flat plate collector and sponge increases the overall temperature of the still water and enhance the evaporation respectively thereby this will improve the condensate production of the solar still. It was observed that productivity increased by 14% in case of still with a collector, 10% for still with a sponge and 17% for still with collector sponge combination when compared with simple still.
