to what extent has water scarcity affected delhi?

Answer 1

According to a World Bank study, of the 27 Asian cities with populations of over 1,000,000, Chennai and Delhi are ranked as the worst performing metropolitan cities in terms of hours of water availability per day, while Mumbai is ranked as second worst performer and Calcutta fourth worst (Source: Background Paper - International Conference on New Perspectives on Water for Urban & Rural India - 18-19 September, 2001, New Delhi.)
Delhi: The nation's capital is perpetually in the grip of a water crisis, more so during the dry season, when the situation gets particularly worse. As the demand-supply gap widens, more groundwater is being exploited. Of the water supplied by the municipality, approximately 11 per cent comes from groundwater reserves and remaining from the Yamuna river. It is, however, difficult to establish the total quantity of groundwater extracted because a large number of tubewells (owned by individuals, industries and bottled water companies) remain unregistered.
NEW DELHI: This could figure in Ripley’s believe it or not! Summer sizzle has not spared even the country’s first citizen from getting exposed to harsh urban realities. Rashtrapati Bhavan, one of the most imposing symbols overlooking the Republic’s corridors of power, is facing water shortage. You may even get to see tankers supplying water to the president’s estate — just like a shoddy lane tucked away in a corner of any metro.

Faced with water shortage, Rashtrapati Bhavan officials have sought additional supplies from Delhi Jal Board (DJB). With summer scorching the capital, the situation is such that president’s estate wants DJB to supply water on immediate basis through tankers. When contacted, DJB member(water supply) RK Garg told ET: “We have received a correspondence from Rashtrapati Bhavan on the water situation. We have resorted to immediate action. The Upper Yamuna Board has also been apprised of the situation.”
