Mumbai’s historic Banganga Tank has undergone a significant restoration effort, with civic authorities removing 10 metric tonnes of floral and ritual waste over a three-day cleanup drive. In addition, six aeration pumps were installed to improve water quality, boost oxygen levels, and safeguard aquatic life, addressing the recurring environmental challenges that follow the Pitru Paksha rituals.
The cleanup comes after disturbing reports of dead fish surfaced in the tank, highlighting the environmental consequences of ritual offerings. Officials noted that despite prior advisories, large quantities of flowers, food offerings, and other organic material continue to pollute the water, causing oxygen depletion and mass fish deaths. “Our repeated appeals to citizens to use collection bins and artificial ponds during rituals are often overlooked, leading to this annual challenge,” stated a BMC official from D Ward overseeing the operations. During the Pitru Paksha period, Banganga Tank attracts thousands of devotees performing pind daan ceremonies. To manage waste effectively, the civic body had installed dedicated collection bins, mobile toilets, and temporary storage containers across the site. Despite these measures, officials observed that some ritual materials were still discarded into the tank, necessitating a large-scale removal effort.
The BMC’s Solid Waste Management Department executed the operation systematically, collecting six metric tonnes on the first day of the drive, followed by two tonnes each on the subsequent days. The cleanup not only involved physical removal of floral debris but also water recirculation to restore oxygen levels, a critical factor for fish survival. “Water was continuously pumped out and aerated before being reintroduced, ensuring the dissolved oxygen levels improved significantly,” the official added. Experts note that while such cleanup drives address immediate concerns, long-term ecological sustainability requires enhanced public awareness and stricter enforcement during religious ceremonies. Environmentalists have suggested integrating green practices into rituals, such as biodegradable offerings and centralised collection points, to reduce the recurring pollution cycle.
The initiative reflects Mumbai’s broader commitment to maintaining eco-friendly and sustainable urban water bodies. By combining mechanical intervention with citizen engagement, authorities aim to create a model for urban heritage site conservation that balances cultural practices with environmental responsibility. The BMC also intends to monitor water quality regularly, ensuring aquatic life thrives and the tank remains a safe, clean landmark for residents and visitors.
