Ah, the ol' argument of boiled water will kill you. I used to get so worked up about this. It is astounding how persistent some cultural superstitions are.
The other belief that I feel best matches this one is that turning on the air conditioning during winter will stop people from catching colds.

@ray98, I am pretty sure that water treatment doesn't involve distillation. The energy cost would be astronomical, and the volumes a plant could process would be tiny.
I think that water treatment is mainly filtration, possibly with other processes thrown in.
The water treatment on the WSD website is filtration, chlorination (and a few other chemicals), fluoride added for good measure before it goes into circulation.
Let me explain. When I was a nipper, in our village, there were no direct water supplies to a house, we all used one communal tap for the whole village, so that meant storing water in buckets and it was advisable to boil the water before drinking. Over time, it became a habit, not just for villagers but Hong Kong generally - I think that's why many workplaces contract Watsons to supply drinking water today. My parents didn't lose this habit when we got to the UK, partially out of habit but partially to have a ready supply of hot water in a vacuum flask for making Chinese tea.
