You are right, I should have specified that tap water quality doesn't include the taste of it.

Apart from that Belgium tap water is perfectly safe to drink! I don't know specifics about the tap water in Belgium but something as simple as a carbon filter removes Chlorine and a lot of the bad taste!

I have been to Belgium before, to Brussels and Leuven, as far as I remember I liked the tap water better in Leuven, but that's just anecdotal. What I want to say with that is that tap water usually varies from area to area.
