TATA Swach® Nanotech Water Purifier
 |
|
The vision for TATA Swach® is to reduce the incidence of water
borne diseases by making safe drinking water accessible to the “have-not's”. |
|
|
|
The key component of the TATA Swach® water purifier is its cartridge,
the TATA Swach® Bulb™. This bulb runs on its unique advanced TSRF technology, around
which 14 patents have been filed so far. The Tata Swach ® Bulb purifies upto 3000
liters of water and like an electric bulb, it fuses after its power expires and
prevents water from passing once its purifying capacity is exhausted. |
|
|
|
TATA Swach® is the world’s lowest cost purifier,
providing safe drinking water at 12 paise per liter. |
|
|
|
It is not only effective against water borne bacteria and virus, but also meets
the USEPA performance norms for bacteria. |
|
|
|
|
|
A unique feature in the TATA Swach® bulb is the TATA Swach® Fuse™. |
|
|
|
The TATA Swach® bulb is packed with a purification medium which
has the capability to kill bacteria & disease causing organisms. In the process
of killing, the purification power of the admixture gets consumed and after around
3000 liters, this gets completely exhausted, rendering the bulb ineffective.
|
|
|
|
However, impure (bacteria laden) water & pure water may both appear “clear”
& almost similar to the naked eye. It was thus important that the user is made
aware when the purification capacity of the admixture gets exhausted so as to ensure
that the user replaces the Tata Swach bulb in time and thereby protects herself
from drinking impure water.
|
|
|
|
To achieve this, a unique fuse is incorporated which functions as auto-shut-off
technique which actually stops the water flow when the purifying capacity gets exhausted. |
|
|
|
The fuse also has the ability to indicate remaining life and consumed life of the
cartridge, thereby giving the user enough warning & lead-time for procurement. |
|
|
|
The TATA Swach® Lock™ is an additional feature which ensures that
the user always gets an original TATA Swach® Bulb™
and is hence protected from counterfeits which might have a negative impact on his
/ his family’s health directly. |
|
|
|
|
TATA Swach® has been an instance of collaboration between various
Tata Group companies. It was an idea that originated with TCS and was subsequently
picked up by Tata Chemicals and a joint team of both the companies improved &
perfected the technology and made the product meet USEPA standards. |
|
|
|
When the product was ready, the team realized that no off-the-shelf production machine
or process was available to mass manufacture such a product. The team discovered
that another Tata Group company, Titan Industries (makers of watches & other
precision instruments) had expertise in supplying automation solutions by using
its precision engineering capability arising out of watch manufacturing. Titan developed
the special assembly presses to undertake mass production. |
|
|
|
Thereafter, as TATA Swach® readied launch, help was sought from
Tata Business Support Solutions and Tata Teleservices Ltd to provide call center
and toll-free number facilities, as part of after-sales-service backbone for the
product. |
