What is the ruling on selling water?

Water originating from owned land is the property of its owner. He is permitted to utilize it and sell it. He also has the right to prevent others from accessing it, except in cases of extreme necessity, such as for drinking. As for other types of water, selling them is not permissible. Accordingly, there are four types of water: private, public, rainwater and floodwater, and well water in deserts. Each has its own ruling regarding ownership and utilization. If a person prepares ponds to collect rainwater, he owns the water collected in them, and selling it is permissible.
