Why is the Delhi Jal Board seeking NGT permission for borewells in the O-zone?

The Delhi Jal Board is seeking NGT permission to operationalize over 100 borewells in the O-zone to augment water supply ahead of the peak summer months.

How much water could the new borewells supply to Delhi?

Once approved and made functional, the borewells are expected to add an estimated 30-40 million gallons per day to Delhi's daily water supply.

What are the concerns regarding increased groundwater extraction in Delhi?

Experts are concerned that over 40% of Delhi's groundwater is already overexploited, and further extraction could increase the risk of aquifer contamination and is not sustainable.

Delhi eyes O-zone borewells for summer water

The Delhi Jal Board (DJB) has submitted a proposal to the National Green Tribunal (NGT) requesting authorization to operationalize more than 100 borewells. These borewells are situated in the O-zone, an ecologically sensitive area along the Yamuna floodplains where construction is generally prohibited. The objective is to significantly augment the city's water supply in anticipation of the increased demand during the upcoming summer months.

Officials estimate that once functional, these borewells could contribute an additional 30-40 million gallons of water daily to Delhi's supply. This initiative is part of broader efforts to bridge the gap between the city's current water supply capacity of approximately 1,000 MGD and its peak demand, estimated at around 1,260 MGD.
