This bit is almost certainly made up somewhere in the information chain of this article.

I grew up in an Indian village, not so well off. So were most of my relatives in the neighboring villages. I never witnessed or heard of such a thing.

In some places (covering around 5-10% population of India) there is a tradition of washing the feet of your elders on some ceremonial occasions but that water is never consumed. It mostly goes to some sacred tree or as an offering to some local deity, meaning that it is thrown around the deity in symbolism.

Edit: grammar

Some segements which are more pious do in fact, consume a small amount of water - but I've not heard of it happening as a daily ritual - only during ceremonies.
