New Delhi: The demand for water in the country for various purposes, including irrigation, drinking and energy, will increase to over a thousand billion cubic meters in 2025 from the present 81,30,000 crore litres, a Planning Commission report said.
The demand for irrigation in the country will increase by several billion cubic meters in the next 15 years. While it is estimated that farmers will require 688 billion cubic meters (BCM) of water for irrigation in 2010, the demand will increase to 910 BCM in 2025.
While the demand for drinking water is pegged at 56 BCM during the next year, it will increase to 73 BCM in 2025, the report of the Steering Committee of Planning Commission on Water Resources for 11th Five Year Plan (2007-12) said.
The report has quoted the data given by the standing committee of the ministry of water resources.
Similarly, while the industry requires 12 BCM of water per annum, the demand will increase to 23 BCM after 15 years. For generating hydro electric power, India will require 15 billion cubic meters of water compared to the 5 billion cubic meters it will require next year, the report adds.
‘Other’ users would require 72 BCM of water in 2025, while their demand during the next year has been pegged at 52 BCM, the report said.
In 15% of the blocks in the country, the annual extraction of ground water exceeds annual recharge and in 4% of the blocks it is more than 90% of recharge.
As the ground water recedes, wells have to be deepened and more energy has to be used to pump water, the report said.
