India, Jan. 28 -- In a bid to address future drinking water needs of the national Capital, the Delhi Jal Board (DJB) is planning an extensive survey of borewells to ascertain the volume of groundwater extraction.

According to officials, with limited water sources of its own, the city's dependence on groundwater is likely to increase in the future, prompting the need for a new borewell policy.

"By 2051, the population projection is 3.21 crore, for which approximately 1,566 MGD of water will be required. With no new sources of water expected to emerge in the near future, the supply needs would be primarily dependent on groundwater," a government official said.
