If you do not have a house or permits yet, then any advice we could give would be acedemic. The county building department would have to okay any pump system and their requirements would determine whether you could build the house or not. I know that around here, the main sewer has to be extended to the property line before the lot can be connected to it. If they allowed a connection to the remote sewer system, you would most likely have to obtain easements from any intermediate property owners. But as an academic answer, if the pump is sized correctly, it can pump to almost any distance.
