Some countries have a law that permits communities to secure the right of access to water sources owned by private parties. This law can be enforced (with fair compensation in general for the owner) . However the law is not enough. Local governments ( municialities) ar often loath to apply the law especially when th owner of the water source is a powerful landowner or cattle rancher.
