Not the same thing, but we have an easement along the back property line that was originally for "occasional" access to power lines and a sewer trunk line that follows the property line as well. There is an old gravel "road" that predates the subdivision for access.
The power line guys are at most an occasional foray for branch lopping--in fact I can't remember the last time I saw them use it.
The sewer guys on the other hand have adopted it like their own road--almost daily access with their 4x4s. They rebuilt the pumping station that is at the end of the old easement road, and now they drive down almost daily, and perform "tests" and sleep in their trucks. What's worse is they also have dumped loads of asphalt millings and gravel and regraded a road that they do not own, and for which there is no permission given for them to do so.
When I have questioned them (and asked politely not to block my own little back "entrance" off the old road while they have done so), all I have got was attitude and they have just let the **** pile up so it is harder for me to get onto the usable part of my driveway.
Meanwhile it has also become the informal walking path for the dog walkers, since it joins up with the small public park at the end of the old road.
I've gone far enough to know that the Sewer District guys are taking advantage, and who the local lawyer is who has had success teaching folks like this some manners, but so far have not had the spare cash to get the matter solved, either the the county purchase of the whole easement or other arrangements.
