how much is Coca-Cola[1][2] to blame for this. Afaik it has been the center of criticism in India for over a decade now:
Coca-Cola operates 58 water-intensive bottling plants in India. In the southern Indian village of Plachimada in Kerala state, for example, persistent droughts have dried up groundwater and local wells, forcing many residents to rely on water supplies trucked in daily by the government.
I'll assume that every ounce of bottled water or soft drink replaces water that people would have drank anyway, and possibly with more efficiency - a larger percentage of the (expensive) bottled water gets used on the unalienable human need to drink than if the same water was piped to houses and used for both drinking and washing.
The plants may be blamed for transferring water scarcity from places where the drinks are bought and drunk to the places where the bottling plants are operated, but not for creating water scarcity.
