Drinking water in restaurants

Drinking water in restaurants

I have been reading with interest the comments from people in
your Speaker's Corner for the past few days.

We all know that water from a faucet in Indonesia is not safe
to drink. During a recent trip overseas I noticed that many
restaurants have notices to say that the water used in their
restaurant is purified. I never see those signs here.

Somebody told me that this is because restaurants here (even
expensive ones) just use tap water in their cooking, for making
ice, and even in the drinks they serve. Can this possibly be
true? Isn't this dangerous for our health? Aren't we entitled to
know whether the drinks they serve are safe, and the food is
cooked in clean water?

Are there any regulations about this? If so, who is in charge
of making sure that these regulations are followed?
