Once the water cools you can put it into a bottle. I prefer glass. I used to be able to get 2L but the biggest now is 1.7L. I then put the bottle of water into the fridge to finish cooling. And then everyone can just take a glass and pour what they want in. I usually do a bottle in the morning and about lunch time. Obviously it gives a bit extra work. But it is more costly to buy bottled all the time.
