Robbery at Charleroi airport

At Charleroi airport a small bottle of still water costs 3.30 euro.
And you cannot bring your water with you, because, for quite obscure reasons, water do not pass the embarquement control.
Isn’t there a sort of association for crime?
Shouldn’t the airport authorities being obliged to install free fountains after the control?
Water is a public good. Even on the plane.
