I probably don't use as much water as some of you do, but I have to say that I have not used a hose in years.
I have two 5 litre containers that came when I bought drinking water somewhere. The label is long gone, I think it was in Spain. They are strongly built of thick plastic and have a nice handle - you don't see them every day, so I kept them. One is for refilling my tank. The other is for drinking water only.
The one for filling the tank is kept full and that is my reserve water for when the tank runs dry. That has happened exactly once, when I didn't see any source of water for over a week.
Otherwise, I fill the tank with the container. My tank says it is 34 litres, but seems to be less than 30. So worst case, it is 6 trips to the tap. Usually it is only 2 or 3 and that is about twice a week.
I'll bet that most of the time I can refill in less time than if I had to fool with unreeling a hose, getting it to work, and reeling it back up again.
I understand that this is not so useful if you go through a 100 litres a week...
Here in the French Alps, there are fountains and springs all over the place, so clean water is easy to come by. I bet nobody has a hose attachment to fit a 500 year old fountain outlet.
