Groundwater extraction for domestic purposes, especially in Delhi and its neighboring NCR districts, significantly contributes to the total withdrawals, according to government data shared in the Lok Sabha. The Minister of State for Jal Shakti, Raj Bhushan Choudhary, highlighted that 71.88% of Delhi's extracted groundwater is used for domestic needs.
Choudhary noted that the Central Ground Water Authority (CGWA) regulates extraction, issuing No Objection Certificates as per its guidelines. These guidelines, established on September 24, 2020, include charges for extraction based on quantum-linked slabs and compliance requirements. Enforcement includes penalties and environmental charges for illegal practices.
The installation of digital water flow meters is compulsory in all residential water extraction points. Moreover, rainwater harvesting is mandated for buildings on plots sized 100 square meters or larger. The 2025 post-monsoon assessment revealed a nationwide increase in groundwater levels, though some areas still face seasonal challenges due to various factors, including urbanization and climate change.
