National Water Policy is finalised and adopted by
National Water Resources Council. Several States have formulated their
State Water Policies, by and large as per the provisions of National
Water Policy. The States implement these policies as per their
requirement and priorities.
The third Minor Irrigation Census has counted 5.56 lakh tanks and
storages in India. The storage capacity of these tanks and storages was
not surveyed.
The average annual water availability for the country has been assessed
as 1869 billion cubic meters (BCM). Due to topographic, hydrological
and other constraints, the utilizable water has been estimated to be
about 1123 BCM comprising 690 BCM of surface water and 433 BCM of
replenishable ground water. The National Commission for Integrated Water
Resources Development (NCIWRD), in its report in 1999, had assessed
that the annual water requirement by the year 2025 and 2050 will be
about 843 BCM and 1180 BCM respectively.
