The 'Dagduseth Halwai' Ganesh idol in Pune was immersed after a 20-hour long procession.
The immersion processions of Ganesh idols had begun yesterday amidst much fanfare and tight security, marking the culmination of the Ganesh festival that began on August 25.
Around 7,000 'sarvajanik' (public) idols and over 33,000 'gharguti' (home) idols were immersed here till 7 am today at various spots, which included beaches, natural and artificial ponds, an official from the Brihanmumbai Municipal Corporation (BMC) told PTI.
Many idols were immersed in artificial ponds, set up by the BMC to prevent pollution of natural water bodies.
Chanting 'Ganpati Bappa Moraya, pudhchya varshi lavkar yaa' (Lord, come back quickly next year), devotees from all walks of life and age groups flooded the streets.
The lengthy processions could not dampen the spirit of the devotees who were seen singing and dancing on the streets.
The authorities had also deployed helicopters and drones for surveillance.
Lifeguards were deployed at various water bodies, while control cells and first-aid centres were set up across the city. Motor boats and ambulances were also kept ready for any exigency.
The civic body had also set up portable toilets.
As many as 9,000 BMC employees oversaw the immersion proceedings.
The BMC had appealed devotees to inform the civic authorities if they needed any assistance or if they were stung by jelly fish or sting ray along the beaches.
