It’s a known fact that in many parts of the world, a basic requirement such as clean drinking water, is still not available. Be it poverty or any other factor it brings us face to face with a dreadful situation.Here’s a water purifier introduced by Tata in India which looks like a real wonder for the not so privileged because it doesn’t run on electricity nor does it need flowing water for activation.

A 2 feet tall purifier, it involves a filter made of paddy husk ash [has an effective cleansing ability] with particles of microscopic silver [kills waterborne bacteria] that has the capacity to purify 3000 liters of water before being substituted by a new one.

It has been named the Tata Swach and will be  available in the form of 19-litre Swach models one of which is priced at Rs.749.00 ($16.11) and the other at Rs.999.00 ($21.48)[materials differ]. Originally planned for use in Tsunami affected areas this sure does look like a boon not only for the billion people unable to access clean drinking water but for use in emergency situations as well.
