Which law is that? And in which language?
In French for example "potable" means "drinkable (without problems)"
I think you are a little inaccurate with your suggestion that
drinking_water is an antonym of waste water/sewage. There is plenty of
water out there which is neither - lakes and rainwater for example, and
plenty of water which is even worse than sewage (industrial waste
stuff).
