In order to run water lines, power lines, gas lines, etc. on your property you have to (or at one time the original owners of the property) sign a right-of-way which is "giving" that person ownership of that piece of your property to do their business. This also gives them the right to do upkeep, maintainance, whatever they need to do, or want to do legally. To see who gave them the right to be on your property you need to look at your property easement which you should have gotten when you purchased your land. The title company (that you had to pay) is supposed to reserch this for you so you know. That's their job. You can also go look up easements at the courthouse on the land plot map. The prob is that once the easement is given (reguardless of who or how long ago) it stays with the property from now on. As belonging to that entity, they can do with it as the want. You no longer own that area. Also, the mineral rights, if not sold to someone else by original owners or an owner before you, stay with the land an are therfore yours--ie to the center of the earth. Most mineral rights were sold years ago to corporations therefore you don't own to the center of the earth unless you have the mineral rights to your land. This can also be checked at the courthouse--who owns the mineral rights. That being said, you CAN NOT sell the sky above your property nor can someone buy it. You DO own it, and as such it can be tresspassed upon. What I'm getting at is if you climb the pole, it's THEIR POLE even if it's on your property---tresspassing. If you dig the gas main, it's THEIR GAS MAIN even if it's on your property. But it's YOUR AIR----tresspassing on THEIR part. -----Or I might be all wrong.
