There Are Reasons Why Some Things Aren't Done

Quite:

Members of Alberta's Hindu community are asking the City of Calgary to provide a designated spot along the banks of the Bow River to scatter the ashes of loved ones, in line with their faith.

It's traditional in Hinduism and other religions, including Sikhism, for ashes to be placed into flowing water after a cremation. Similar riverside spaces for the ritual have been provided around the world in cities that have large Hindu communities.

 

I'll leave this here: 

Manoj explains, “According to Hindu rituals, ashes or ‘Asthiyan’ are not taken home after cremation. The kalash containing ashes has to be left with a purohit at the ghat who charges exhorbitantly. After a few days, while performing rituals, the ashes are immersed in Ganga. But the ritual adds to the pollution in the river Ganga or other river in which the ashes are immersed. We therefore, had decided to set up a ‘Asthi Kalash’ bank and encourage people to bury ashes in ground.”
