About 74 per cent of India's total population, currently about 1.25 billion, live in rural areas. More than one third of the water available to them is not potable. In a grim reminder that poor quality of drinking water leads to serious health problems, India has admitted that about 180,000 rural populated areas are afflicted by diseases which are caused due to impure, toxic organic and inorganic substances including tri-halo methane, chlorine, etc. Some states have reported multiple contaminations in drinking water and there is no doubt that the current water situation in India will get much, much worse unless suitable solutions are sought. Most existing purification methods not only remove the impurities but drain out the essential minerals as well. Moreover, they are expensive and require extensive maintenance. Thus a natural filter comprising of bamboo, gravel, pebble and other locally available natural adsorbents is a great alternative to carry out water purification. What makes this filter unique is the use of bamboo charcoal which is not commonly used in any filter designed for domestic purposes.
