Abstract: Clean potable water is a human birthright as much as clean air. Its demand increasing day by day due to several factors, viz. industrialization and human’s population growth around the globe etc. Solar stills have long been recognized to have clean and potable water in remote areas. Easy-to-operate and very low maintenance may be one of the major regions behind it. In present work, the real situation near the seashores, where wet sand is available in abundance quantity containing brackish water. A laboratory scale of 1m2 basin area has been used to conduct experimentation Experimental result paves the way to have purified water on the coastal area using solar energy only with a low-cost setup. The two experimental arrangements were compared for the heat and mass transfer within the single slope solar still and the yield in the month of May at Raipur (Latitude 21.16N and longitude 81.42 E) India. It has been observed that the daily distillation yield is more in the second case where the surrounding mass of sand has been converted as heat storage that enhances heat and mass transfer. The wet sand top surface temperature that resembles the water temperature of solar still of both arrangements and a neural network model was developed to forecast the yield of solar still considering nine input parameters
