Which ones? At least several of the largest theme parks chains do offer free water, you can google it. Many allow bringing refillable bottles. I’d speculate it might be a medical liability issue to not offer tap water to guests in a closed environment summer activity. None of that changes whether it’s profitable or a good idea to give away water or drinks. https://www.themeparkinsider.com/flume/200908/1350/ https://www.themeparkinsider.com/flume/200908/1350/
