¶ Pilot Project^[1]

• These wells are designed in-house by Delhi Govt itself, led by Satyendar Jain^[2]
• As part of a pilot project to determine whether the use of modern technology can result in more water augmentation or not
• Delhi government constructed 30 Modern extraction wells in Oct 2021
• Constructed in the premises of Sonia Vihar Water Treatment Plant

Result: After the success of the pilot project the government will now build 70 more such wells in the same premises spread over 150 acres

¶ What are Modern Extration Wells^[1:1]

• High Capacity: These “modern extraction wells” can provide 6-8 times more water than ordinary wells. The capacity of each well is to supply 1.2-1.6 million gallons of water per day (MGD)
• Bigger than Ordinary wells: Ordinary wells have a diameter of 0.3 metre while these new wells have a diameter of 1-1.5 metres and a depth of 30 metres
• NO WTP required: The modern wells are designed in such a way that water gets purified within the premises and does not require any additional water treatment
• No effect on groundwater levels: The groundwater will be automatically replenished during the rainy season, so the extraction of water from the well will not have much effect on groundwater levels
