The Delhi government is considering making rainwater harvesting mandatory for all new borewell permissions as part of efforts to address the city’s worsening groundwater situation. The proposed measure aims to ensure that groundwater extraction is balanced with recharge activities, especially as several areas face declining water tables due to excessive withdrawal. The proposal was announced by Delhi Public Works Department (PWD) and Water Minister Parvesh Sahib Singh Verma, who said the government is examining ways to link borewell approvals with groundwater conservation measures.

He stated that the move would help ensure that groundwater extracted through borewells is matched by efforts to replenish underground water reserves. “The government is examining measures to make rainwater harvesting mandatory for all new borewell permissions, ensuring that groundwater extraction is matched by groundwater recharge,” Verma said. The proposal is part of broader efforts to improve water management in the national capital, where groundwater levels have become a growing concern due to rising demand and limited natural replenishment.

The proposed rule has not yet been officially notified by the Delhi government. Authorities have also not announced the timeline for implementation, the categories of properties that would come under the regulation or the specific technical requirements that applicants would need to fulfil before receiving permission for a new borewell. Under the proposed framework, individuals or organisations seeking approval for a new borewell may have to demonstrate that rainwater falling on their property can be collected and directed towards groundwater recharge systems. This could involve installing rainwater harvesting structures designed to capture runoff and allow it to seep back into underground aquifers.

The move comes amid concerns over the rapid depletion of groundwater resources in Delhi. In many parts of the city, groundwater is being extracted at a faster rate than it is naturally replenished, leading to falling water levels and increased pressure on existing water supply systems. Rainwater harvesting has been promoted as an effective method to conserve water and improve groundwater availability. By collecting rainfall during the monsoon season and using it for recharge, authorities aim to reduce dependence on underground water sources and improve long-term water security.

Delhi has previously introduced measures encouraging rainwater harvesting in buildings and institutions, but implementation and compliance have remained challenges. The proposed link between borewell permissions and recharge systems could make groundwater conservation a mandatory part of new extraction projects. Experts have repeatedly highlighted the need for sustainable groundwater management in rapidly growing cities like Delhi.

Increased urbanisation, reduced open spaces and heavy dependence on borewells have affected the natural recharge process, making conservation measures increasingly important. If implemented, the proposed policy could change the process of obtaining new borewell approvals in Delhi by making water conservation an essential requirement. The government is expected to finalise details after further examination, including technical guidelines and the scope of properties that would be covered under the new framework.
