Rainwater Harvesting Scenario in 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.

In Delhi approximately 13 per cent (Source: Zerah., M Helene, 2000, Water – Unreliable Supply in Delhi, French Research Institute of India) households do not receive water every day and in Rajkot, Gujarat, water availability in April 2000 was only for 30 minutes every alternate day.
