Farmers in Coimbatore and Tiruppur have expressed grave concerns over the environmental impact of idol immersions during Vinayaka Chathurthi. Despite strict government guidelines on materials, the sheer volume of idols remains a critical threat to local water bodies.

  • TNPCB has banned Plaster of Paris (PoP), toxic dyes, and single-use plastics for idol making.
  • Designated sites like Sulur Lake and Vellakinar pond have been identified to prevent river pollution.
  • Farmers argue that the increasing quantity of idols offsets the benefits of using eco-friendly materials.

As the festivities of Vinayaka Chathurthi unfold, a significant environmental concern has emerged in the Coimbatore and Tiruppur districts of Tamil Nadu. While the district administrations have implemented strict protocols regarding the immersion of idols, local farmers are sounding the alarm over the escalating number of idols being immersed in water bodies, which they claim threatens the long-term health of their irrigation sources.

The Tamil Nadu Pollution Control Board (TNPCB), adhering to Central Pollution Control Board (CPCB) guidelines, has issued a comprehensive set of restrictions. These include a total ban on Plaster of Paris (PoP), harmful chemicals, thermocol, and synthetic dyes. The board has strongly advocated for the use of natural tree resins, straw, and dry flower components for idol decoration to ensure biodegradability.

Why This Matters

BozokMedia analysis shows that the transition to 'eco-friendly' clay idols is a step in the right direction, but it does not solve the problem of sedimentation. When thousands of clay idols are immersed in a small pond, they settle at the bottom, reducing the water-holding capacity and altering the chemical composition of the bed. G. Ranganathan, president of the Tamizhaga Vivasayigal Sangam (Coimbatore unit), noted that while material restrictions are welcome, the authorities are powerless to curb the sheer quantity of idols produced.

"The shift to clay is positive, but the scale of immersion is becoming unsustainable for our fragile freshwater ecosystems."

In Coimbatore, the administration has attempted to mitigate damage by designating Sulur Lake for the northern region and Vellakinar pond for the southern region. To prevent haphazard pollution, cranes will be used for immersion in Sulur, and tankers will provide water in Vellakinar. In a sustainable twist, the accumulated clay from the dissolved idols will later be repurposed to strengthen the lake bunds.

However, the situation in Tiruppur is more contentious. The Samalapuram Lake has been the designated site for the past 20 years. K.S. Thirugnanasambandan, chief coordinator of the Tamizhaga Noyyal Vivasayigal Padhukappu Sangam, has criticized this decision, stating that the lake is already heavily polluted. He argues that immersing 'purified' idols into an impure water body is contradictory and advocates for the identification of new, cleaner sites.

Did You Know?: Even 'natural' clay idols can cause anaerobic conditions at the bottom of ponds if immersed in excessive quantities, potentially killing bottom-dwelling aquatic organisms.
