Delhi government plans reclaimed water policy to ease scarcity

The Delhi government has begun preparations to launch a comprehensive reclaimed water policy scheduled for 2026, marking a significant step toward tackling the city's persistent water shortage challenges. The policy framework is designed to promote the utilization of treated wastewater in sectors traditionally dependent on freshwater supplies.

Under the proposed policy, construction projects and horticultural operations will be encouraged—and potentially mandated—to adopt treated reclaimed water for their operations. This shift aims to reduce the burden on the city's freshwater reserves while creating a sustainable alternative water supply stream for non-potable applications.

The initiative reflects growing recognition among urban planners that water recycling and reuse can significantly mitigate supply constraints in metropolitan areas. Construction sites generate substantial water demands for concrete mixing, dust control, and other processes, while gardens and landscaping projects similarly consume considerable quantities of water. By redirecting treated wastewater to these sectors, the policy seeks to free up freshwater resources for domestic consumption.

The reclaimed water policy is part of broader water management strategies being implemented across Indian cities grappling with seasonal shortages and climate variability. If implemented effectively, the 2026 policy could serve as a model for other water-stressed urban centers in the region seeking sustainable alternatives to conventional water sourcing.
