27- WATER RESOURCES
THE Ministry of Water Resources, River Development, and Ganga Rejuvenation lays down policies and programs for the development and regulation of the water resources of the country. It covers sectoral planning, coordination, policy guidelines, technical examination and techno-economic appraisal of projects, providing central assistance to specific projects, facilitation of external assistance and assistance in the resolution of inter-state water disputes, policy formulation, planning and guidance in respect of major, medium and minor irrigation, groundwater management, command area development, flood management, dam safety and river development and Ganga rejuvenation (including its tributaries rejuvenation), regulation and development of inter-state rivers, implementation of awards of Tribunals, water quality assessment, bilateral/external assistance and matters relating to rivers common to India and neighboring countries.

- The average annual water availability of any region or country is largely dependent upon hydro-meteorological and geological factors and is generally constant.
- As per National Commission on Integrated Water Resources Development (NCIWRD) report, the total water availability of the country received through precipitation is about 4000 Billion Cubic Meter (BCM) per annum.
- After evaporation, 1869 BCM water is available as a natural runoff.
- Due to geological and other factors, the utilizable water availability is limited to 1137 BCM per annum comprising 690 BCM of surface water and 447 BCM of replenishable groundwater.
- The average annual per capita water availability in the years 2001 and 2011 was assessed as 1820 cubic meters and 1545 cubic meters respectively which may reduce further to 1340 and 1140 in the years 2025 and 2050 respectively.
- Water stressed condition: Annual per-capita water availability of less than 1700 cubic meters.
- Water scarcity condition: Annual per-capita water availability below 1000 cubic meters.
- Due to the high temporal and spatial variation of precipitation, the water availability of many regions of the country is much below the national average and can be considered as water-stressed / water scarce.
- Total requirement of the country for different uses for high demand scenarios for the years 2025 and 2050 has been assessed as 843 BCM and 1180 BCM respectively.
National Water Policy

- It accounts for 28 percent of India’s water resources, holds about 26 percent of India’s landmass, and hosts 43 percent of the population.
- The main stem of the river traverses 5 major states namely, Uttarakhand, Uttar Pradesh, Bihar, Jharkhand, and West Bengal, and travels 2525 kms.
- The Ganga River basin including all its tributaries covers about a million square kilometers area in 11 states in the country.
- The river is home to some exotic marine life such as gharials, turtles, Gangetic dolphins, and golden mahseer etc.
- On important religious/spiritual days, millions of people converge on its banks in select cities to pray and bathe in the waters, and for them, a clean Ganga holds great value.
- More than 120 million people came to the city of Allahabad for pilgrimage in 2013, making it the largest gathering in the world.
- The major source of pollution in the river is untreated domestic and industrial liquid waste thrown into it.
- About 70 percent of the pollution is from untreated domestic sewage, 20 percent is from toxic industrial wastewater and 10 percent is from non-point sources such as agricultural runoff, open defecation, dumping of solid waste disposal, etc.
