Well good luck with that (sneaking in another well). In parts of Texas irrigation wells are already metered with plans to meter domestic wells on the drawing board. You won't find a well driller anywhere that will drill an unauthorized well. It's illegal and they'd lose their license. Plus the authorities have GPS reading and aerial views of all property within their jurisdiction.

That certainly sounds like it would be a challenge.

BTW... I wouldn’t even try to get a well driller involved.

I have what I “think” might be a spring. It’s not near my well.

Using a backhoe I have on my tractor, I have dug down about 6” from what was always a wet spot in a field. I would have gone deeper, but it turns to solid rock, large and thick shale rock.

I have dropped a sump pump into the water filled hole and every time the pump takes the level down, about 40 minutes later, the hole is full of water again. This occurs even during the driest part of the year. The water is clear, smells good and it’s very cold.

I don’t know anything about this stuff, but I think I might have a spring and if I do... there is my extra water source. ;>) At the very least, it seems that I should be able to bury a storage tank in nearby soft ground and use the source to keep it filled for gardening water.
