new intown - don't take things so personally. I gave information about the water supply based on what I've been told and what I've read (the same information others have seen, it appears). Regarding the car washing, I deliberately posted this in a separate comment to try and show that I wasn't misinterpreting your original point. I didn't mention it in relation to drinking water at all. I was simply trying to clarify the point you and MD were arguing about.

If you have information that shows that we shouldn't be drinking the water then please present it here for those who are worried. So far the only arguments you've provided for the water not being safe is the state of the tanks in the house (which I agree with), and that nothing works here in Qatar so we shouldn't expect the state of the art water treatment to work.
