The Maha Kumbh 2025 in Prayagraj, one of the planet’s grandest spiritual congregations, achieved a remarkable milestone by recycling 600 tons of floating waste, blending faith, innovation, and eco-consciousness on an unprecedented scale. With an estimated 55 crore devotees flocking to the Sangam, the Uttar Pradesh Government rolled out ambitious infrastructure and ecological initiatives to elevate the pilgrimage while safeguarding the environment.

A standout effort was the unification of the Ganga’s three divergent streams into a single, seamless flow via a 2.5-kilometre dredging operation. This pioneering project, powered by 83 high-capacity dredgers running non-stop for 20 days, reclaimed 22 hectares of land—expanding the Mela grounds and boosting accessibility. Over six lakh cubic meters of sand and sediment were cleared, enhancing water flow and optimizing space for devotees.

Anil Garg, Principal Secretary of the Irrigation and Water Resources Department, hailed it as a groundbreaking triumph. “Reclaiming land equal to 1,000 tennis courts and enlarging the Sangam area to host two lakh pilgrims simultaneously is a feat etched in history,” he remarked.

Gaurav Chopra, Managing Director and Co-founder of Cleantec Infra, underscored the project’s intensity. “Executing this in just two months was a Herculean task, but we’re proud to have partnered with the UP Government to make it happen,” he said. Three cutting-edge dredging machines worked tirelessly, shifting massive sediment volumes to meet the deadline.

Keeping the Ganga pristine was equally critical. Under the Swachh Bharat Mission, advanced trash-skimming tech was deployed, collecting 10-15 tonnes of floating waste daily—surging to 20-25 tonnes on peak days—culminating in the record-breaking 600-ton haul. “Maintaining the Ganga’s cleanliness amid such a colossal event demanded pinpoint precision,” Chopra noted. “Our skimmers operated 24/7, intercepting waste in real time to keep the water flowing clean. The collected debris was then processed sustainably, reflecting our green commitment.”

Chopra emphasized that mega-events need not sacrifice ecological duty. “We’ve proven sustainable waste management can thrive even at this scale. Mechanized cleaning isn’t just for one-off spectacles—it should be a continuous strategy for India’s water bodies,” he urged.

Maha Kumbh 2025 emerges as a shining testament to how engineering, technology, and environmental stewardship can harmonize to manage massive gatherings while preserving nature. Its innovations offer a scalable playbook for sustainable event management, poised to inspire global gatherings for years to come.
