Legislation on waste/pollution control took into account not only the generators of waste but also the receiving environments. Limits were laid down in terms of standards for effluent or emission. Depending on the type of waste generator, there were specified limits for volume of waste and  characteristics of waste.

The objectives of the case study by TIDE supported by Arghyam on the Tirupur textile industry cluster included:

A national discussion is underway in India on water management issues, with a significant emphasis on decentralization of water supply systems.  Rashtriya Jal Biradari of Rajasthan held a conference in New Delhi in June 2004 (indiatogether.org, July 2004) to propose policies and steps to address India’s water problems.
