Nice rant, but you should read the article.

This has not much to do with water consumption, but it describes to chemically dissolve corpse flesh instead of burning it. The bones will remain and they have to grind them down.

“Water Cremation” just sounds a lot nicer to potential customers and might remind of a funeral at sea. Bringing grandpa to the “Flesh Dissolver” would be a more appropriate term but probably bad for business.
