1. It is the need of the hour that we all immerse ganapati in the cement tanks constructed next to river bed for environmental reasons. Every year i see volunteers pleading devotees to listen to them and immerse the idols in the tanks
2. Devotees think that by doing so they are breaking the tradition and which is sensitive area
If one has to marry above two statements then can we look at fabricating metal tanks (big but not very high) and all sides of these tanks to have holes so water can pass/flow through them. Put these tanks in the river flow. People will immerse the idols in the tanks and after couple of days municipal guys can lift them by crane and do further processing. These can be used through out the year if people have to put nirmalya in the river and so on.
