@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.
You're right it doesn't. I was talking about Watsons distilled water which is also heated to 105 degrees celsius (presumably under high pressure to raise the boiling point of water).
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.
Not quite sure if you are addressing my post.
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.

So out of genuine interest, does your employer (that I assume to be a major international bank), order drinking water at the cost of hundreds of thousands of dollars annually or do they expect their employees to drink tap water?Original Post Deleted
Your answer will rest my case (one way or the other).
I drink from filtered water for 2 reasons:
1. Filtering fluoride
2. Filtering any possible heavy metals out there
I would boil it too if I weren't so lazy to press a water boiling button.
Suit yourself really. I'm concerned mainly cause I don't want to end up brain damaged and then wonder what if I paid more attention to what I take in.
