That was my first thought - how will the water be purified or filtered? Will you need to add a filtration system to your taps? I would be concerned about drinking the water caught in the tank. As Bermy Girl said, our water is purified before it even enters the tank. In the old days, a Bermuda roof was made of limestone slate. Now, with building technology so advanced, they have prepared a white wash that effectively does the same thing.
We were taught the value of water at a young age and practice water conservation in many ways. Don't leave the tap running when you brush your teeth...
