Roof Top Rain Water Harvesting
Various States/Union Territories have made
rainwater harvesting mandatory by enacting laws or by formulating rules &
regulations or by including provisions in Building byelaws or through suitable
Government Orders. Details are given in Annexure. Data on quantum of
rainwater being harvested/ saved in the States is not maintained by any single
agency.
Four States/UT viz. Jammu & Kashmir,
Manipur, Mizoram and Lakshadweep have not made roof top rainwater harvesting
mandatory. In Jammu & Kashmir, as the stage of ground water development is
very low, the state does not feel it necessary to adopt any such regulation. In
Mizoram, rainwater harvesting is already a common practice; hence, the State
Government has not imposed any regulation for making it mandatory. In Manipur,
demonstrative projects of roof top rainwater harvesting are being taken up by
the State Government. In Lakshadweep, due to the hydrogeological conditions,
need for rainwater harvesting is not felt. Besides, Central Ground Water
Authority (CGWA) has been constituted under Section 3(3) of The Environment
Protection Act, 1986 and the Authority has issued directives to the Chief
Secretaries of all States and the Administrators of all UTs to take measures to
promote/adopt artificial recharge to ground water/rainwater harvesting. CGWA
has also taken up the matter with various Central and State government
organizations for adopting rainwater harvesting and recharge to the ground
water. A Model Bill has also been circulated to all the States/UTs which,
inter-alia, has provisions for rainwater harvesting to enable them to enact
ground water legislation for its regulation and management.
Central Ground Water Board (CGWB) has
prepared a conceptual document entitled “Master Plan for Artificial Recharge to
Ground Water in India” which envisages construction of different types of
Artificial Recharge and Rainwater Harvesting structures in the Country by
harnessing surplus monsoon runoff to augment ground water resources. The
Master Plan has been circulated to all State Governments & is also
available in Public Domain.

Resources Minister Shri Harish Rawat in written reply to a written question in
the Lok Sabha
