The Water Protection Act 1974 was enacted to provide for the prevention and control of water pollution in India. It established central and state pollution control boards with powers to regulate pollution. The Act applies to several states and union territories. The Central Pollution Control Board advises the central government on water pollution prevention and assists state boards. State boards implement policies at the state level and regulate industries through consent and standards. Major programs initiated under the Act include the Ganga Action Plan to restore the Ganga river and its tributaries through wastewater treatment in cities and towns located along the rivers.
