Delhi Jal Board (DJB) has announced plans to construct 500 new rainwater harvesting systems across the national capital as part of efforts to strengthen groundwater recharge, improve water conservation, and enhance long-term water security.
The initiative was announced by Delhi Water Minister Parvesh Verma, who said the project forms part of a broader strategy to address groundwater depletion and improve sustainable water management across the city.
According to officials, the proposed rainwater harvesting structures will be installed at suitable locations across Delhi, including government premises, public institutions, residential areas, and other sites identified for groundwater recharge.
The new systems are expected to capture and channel rainwater into the ground during the monsoon season, helping replenish declining groundwater levels while reducing dependence on external water sources.
Officials stated that the project will complement existing rainwater harvesting infrastructure already operational across the city and contribute to improving groundwater availability in water-stressed areas.
The initiative is part of Delhi’s wider water conservation programme aimed at promoting efficient water management practices and increasing resilience against growing water demand driven by urbanisation and population growth.
The Delhi Jal Board has also been working on measures to revive water bodies, reduce water losses, improve distribution infrastructure, and expand wastewater treatment and reuse capabilities as part of its integrated water management strategy.
Experts have highlighted rainwater harvesting as one of the most effective methods for groundwater recharge in urban areas, particularly in cities facing increasing pressure on water resources and recurring groundwater depletion.
Officials noted that the additional 500 systems will help maximise the utilisation of seasonal rainfall, reduce runoff losses, and strengthen Delhi’s efforts toward sustainable urban water management.
The project comes at a time when several Indian cities are focusing on water conservation initiatives, climate resilience measures, and sustainable infrastructure solutions to address future water challenges.
Industry experts believe the large-scale deployment of rainwater harvesting infrastructure can play a significant role in improving groundwater sustainability, reducing water scarcity risks, and supporting long-term urban environmental management across the capital.
