Product development
Tata Swach was designed by Tata Research, Development and Design Centre (TRDDC) and Tata Chemicals with contributions from other Tata group companies. In 2004 the company developed a water purifier called Sujal. Tata Consultancy Services deployed thousands of these filters in the Indian Ocean tsunami disaster of 2004 as part of its relief activities.
