I am a student of IIT Madras. To fight this water crisis situation, we developed a system which can provide pure drinking water to the public. this system generates water using air. it produces the purest form of water which has 6-20 ppm TDS level. WHO recommend TDS level below 500 ppm safe.
we want to install these systems free of cost to slum areas of Chennai where people can't afford water can or tanker.
this system at least solves the drinking water issue. once this system will fulfill requirements in Chennai we can expand it to other cities also.
