As major part of the State was underlain by hard rocks, watershed was taken as assessment unit for the entire State. After excluding hilly areas where slope was more than 20 per cent, the resources were estimated separately for command and non-command areas and separate methodology was used for estimation of groundwater resources for Hyderabad, officials said.
As per resource estimation for 2019-20, the total annual extractable groundwater resources are 15128 million cubic meter (mcm) (command area:6705 and non-command area:8423), which is 22 per cent more in comparison to 2017 resources (12367mcm).
Total groundwater extraction for all uses is 7576mcm (command area:2407 and non-command:5169), six per cent less in comparison to 2017 resources (8094mcm). Net groundwater availability for future irrigation use is 7139 mcm (command area:4197 and non-command: 2942), officials said.
