Thanks for all the replies. Our neighbor is an older gentleman, who's lived in the area between 10 - 15 years and remembers the original owners. We have a copy of the survey and there's no well noted. However, the survey shows the property in it's current layout and this place has been remodeled 2, 3 or more times. The neighbor believes the well is located right near my chicken coop/run, behind the garages, and mentioned that this area is usually green throughout the year. The spot that it could be located is more than 50 feet away and uphill of the septic tank.
What makes us more curious is that there is a chainlink fence that divides the septic area and the chicken area. On the septic side of the fence is a spigot sticking about a foot out of the ground and another knob in the ground. About a foot away on the other side of the fence is another spigot in the ground and another knob in the ground. There's no irrigation sprinklers on this side of the house. The septic is the older style, so we don't have grey water to irrigate with. The septic was pumped shortly after we made our purchase offer and approx. 6" - 12" of dirt had to be removed. So who knows what could be under the dirt?! The President of our POA is a surveyor, so I was also going to ask him to repin our property and see if he could find the well. Otherwise, I'll go ahead and call the appropriate agency and find out if there are records regarding this mysterious well. I'm hoping to get down to the county office sometime soon. I really want to see if I can find the original plans for the house. Right near this area, you can see the old concrete steps that used to lead down from some now-nonexistent door. We keep finding new things about this place. It's only 39 years old, but DH and I find it fascinating when we find something that was part of the original design. Like DDs room used to be a carport, so you can still see the exterior trim in her storage room and there's a spigot too. We removed an ugly welcome sign and found an electrical box for an intercom. We found another intercom piece in the guest house. When we moved in, we found out we had 2 septic tanks, not just one.
Does anyone else live in a house that keeps handing out surprises.
