The Delhi government has earmarked over 30 sites for immersion of Durga idols on Sunday to ensure safety of devotees and compliance with environmental regulations.

According to the regulations, immersion of idols in rivers, including the Sahibi River, a tributary of the Yamuna, is strictly prohibited.

As an alternative, the administration has identified artificial ponds at several places, a statement said, adding that guidelines in this regard were issued to the sub-divisional magistrates (SDMs) a month ago.

The Irrigation and Flood Control Department has been directed to ensure timely completion of these ponds.

SDMs and DDA officials will inspect all sites.

Violation of the guidelines will attract a fine of ₹50,000 enforced by the Delhi Pollution Control Board.
