Mahakumbh 2025: Lessons for India’s Urban Waste Crisis

The Mahakumbh 2025 event, which hosted nearly 660 million people over six weeks, successfully implemented a large-scale, efficient waste management system that offers a blueprint for India's struggling metropolitan cities.
Key strategies included the use of advanced sewage treatment technology, bio-CNG generation, and a dedicated 15,000-person sanitation workforce.
Researchers recommend that the Indian government scale these models by investing in permanent waste-to-energy facilities and adopting circular economy frameworks in urban centers.

The event utilized 10 sewage treatment plants (STPs) treating 340 million liters of sewage daily, employing drain-tapping to protect the Ganga and Yamuna rivers.
Technological innovations included the Hybrid Granular Sequencing Batch Reactor (hgSBR), developed by the Bhabha Atomic Research Centre, to improve water reusability.
Massive temporary sanitation facilities were deployed, including 12,000 fiber-reinforced plastic toilets, 20,000 community urinals, and 16,100 prefabricated steel toilets.

A bio-CNG plant was commissioned to convert wet waste from food and temple offerings into energy and manure.
Many infrastructure assets, such as the STPs and monitoring stations, are permanent and capable of serving nearby localities after the event concludes.
Real-time water quality monitoring stations were established to track pollution levels and encourage public awareness regarding river conservation.

Authors stress the need to formalize the sanitation workforce, addressing issues like caste-based stigma, low wages, and a lack of social security.
Policymakers are encouraged to integrate waste management education into school curricula to foster long-term behavioral change.
Success in urban areas requires strict prohibitions on single-use plastics and sustained budget allocations for waste treatment technology, matching the intensity and planning seen during the event.
