Delhi’s Public Works Department (PWD) and Water Minister Parvesh Sahib Singh Verma propose making rainwater harvesting mandatory for properties seeking permission to drill borewells. The move is intended to address groundwater depletion by requiring recharge measures that offset groundwater extraction. Under the proposal, the requirement links borewell approvals to steps aimed at capturing and storing rainwater, so that water withdrawn from underground sources is matched by additional replenishment. The initiative is framed as a regulatory measure to improve groundwater management in the city and reduce pressure on aquifers. The proposal has been announced by the PWD and the water ministry, but specific implementation details, timelines, and any exemptions are not outlined in the provided reports. Overall, the plan focuses on balancing groundwater use with recharge through rainwater harvesting as a condition for borewell drilling.
