Easements have a way of coming back to haunt you. Prior owners had given a power company a "lease" (very unusual, and not well described in the paperwork) about 100 years ago to run transmission poles across the property. Those poles were removed in the 1950's. The "lease" made the property unsaleable (no one wanted a hassle with the power company). Fortunately, the power company agreed to comply with the law in exchange for $5,000 for "documentation costs". The law was unquestionably on my side. Could have been much worse, so I was glad to pay it.

Will the water line benefit you in any way?
