When I bought my land in Burleson, the previous owner insisted on reserving the rights to any commercial water sales. I specifically made sure the deed stated that the surface owner retained the rights to pump any water that would be used on the property. When I got my well permit, to pump for duck ponds and irrigate trees, it left the head guy at post oak savannah scratching his head because it leaves both owners with full rights to the allotment from under the land. I also wanted to make sure any future owners were protected by the language in the deed. He basically said if it ever came to a head that they wouldn't get in the middle and it would have to be decided by a court.
Suspect there's a lot of water issues that won't be an issue until they are. Maybe 5 years, maybe 500.
