Agricultural irrigation is a far bigger problem, particularly because existing systems are hugely wasteful due to subsidies (water and even the electricity to pump it is often free), leakage and corruption.
> How many litres of water does it take to make a litre of mineral water?
Interesting question, I found this article[1] which says:
- for North American companies, it takes 1.39 liters to make one liter of water
- That's less than the global averages of a liter of soda, which requires 2.02 liters of water
- A liter of beer, meanwhile, needs 4 liters of water, wine demands 4.74 liters. Hard alcohol, it turns out, is the greediest, guzzling 34.55 liters of water for every liter
