Natural water is seldom chemically pure. When it rains, organic and inorganic suspended particulate matter, gases, vapours, mists, etc. in the air get dissolved in water, through which it reaches the earth's surface. In addition, water carries surface pollutants and contaminants during its flow over the ground. Water, which percolates into the ground, dissolves various salts and becomes rich in total dissolved solids. Thus, it acquires a number of impurities while in its natural state. This necessitates adequate treatment of naturally occurring water before it can be used for domestic, industrial, commercial, agricultural or recreational purposes. The extent of treatment will depend on the end use of the treated water. Use of the treated water even once adds considerably to the amount and variety of pollutants. This necessitates further treatment of the water before it can be reused, although it is not strictly necessary to have water of uniformly high quality for each of the above uses. In view of the limited availability of water for meeting our growing demands, and in the interest of protecting the environment, it is essential to think and act in terms of reducing water consumption, reusing and recycling once-used water, and minimizing the pollution effects of waste water resulting from a variety of uses. In this project, a simple technique is introduced to converts dirty water into clean water. The material which are required are Coal (100 grams), Sand (200 grams), Tissue papers and water bottle with cap. These materials are easily available. The requirement of sand and coal depends on the size of the bottle. First take the bottle cap and make some small holes in it and cut the bottom portion of water bottle. After cutting the bottom of the bottle place a tissue paper inside the bottle. In the tissue paper which is inside the bottle put some sand about (100grams) in it. After that wash the coal (100grams) and place over the sand in the bottle and then pour the remaining sand into the bottle. Close the mixture with tissue paper over the water bottle. Now close the water bottle with the cap with small holes. You can pour the dirty water on the top and get clean water in the bottom. This is a simple way of co
