the need for safe drinking water. In India, water-borne diseases
cause more than 1.5 times the deaths caused by Aids and double
the deaths caused by road accidents. With much of India's
population lacking access to safe drinking water or the resources
to source it, the delivery of safe, convenient and affordable
water has been a critical challenge that Tata Swach aims to
Affordable and safe
The vision for Tata Swach is to reduce the incidence of water-borne
diseases by making safe drinking water affordable to millions.
Built around a bulb-like water purifier made of natural rice
husk ash and nano-silver particles, Tata Swach is designed
for convenience and affordability. Tata Swach purifies a litre
of water at a cost of a mere 10paise (100 paise =1rupee; approx
Rs45 = US$1).
Once the purification power of the bulb gets exhausted (after
around 3,000 litres), it stops functioning. Tata Swach has
an additional feature called Tata Swach Lock designed to safeguard
customers from counterfeit products.
Around 14 patents have been filed for the Tata Swach purifier.
Its performance capabilities have been tested across reputed
laboratories in India, the UK and the Netherlands as per USEPA
