The hydrologist in me always asks: why dig a well at the top of the hill? Surely that is more effort than digging it at the bottom of the hill where the water table is closer to the surface.

But I guess wells like this predate modern hydrology. And outhouses and such could be polluting the water as it flows down gradient. So the water at the top of the hill was likely cleaner and safer to drink…

I’d wish for clean drinking water in every well. ;)
