Automatic (Electric) ground water(ing)

The metal shop has an electrical ground that we need to keep moist.

The problem is that it is in a ~1" diameter hole bored in the concrete floor. I wan to feed it as much water as possible while avoiding overflowing onto the floor and creating a puddle. It’s up against the wall behind a bunch of stuff, so a puddle would need to get pretty big before it was noticed.

There seem to be a myriad of automatic soil moisture maintenance schemes for gardening, but I have no experience with these, and I suspect they are both far more complex that we need and likely high maintenance.

Any suggestions on solutions? Maker friendly would be nice.

Apply this same principle

but perhaps with a tube attached to the bottle to feed the 'hole.
Gist: when the water pressure in the lower vessel is low enough for the vacuum in the upper vessel to draw air, water is allowed into the lower vessel in equal volume, so they stay in equilibrium (within a range).
Many variations on the animal-waterer have been used over the years, this was just a cute story about one.

Perfect!

And just use a one or two liter soda bottle and a 3D printed adapter so we can feed a small hose and get the bottle up where it’s visible. .

Up to you, but you can just cut a hole in the lid & stick the hose through…
(not that I want that, as I’d love to know more about how you go about 3dprinting the thing with appropriate screw threads & all, but I suspect there’s a ready-made out there, so I’d learn little to nothing about finding the right thread ptich/diameter specs, etc. so…)

Just thinking about leaks if it’s a few feet off the floor.

Will it be easily bumped, dislodged, etc?

Not if I tywrap it to the ground rod…

Oh, the cap…

Probably not. The bottle will be mounted to the wall. But I’m a firm believer in the old Bell System motto: “build it stout, out of things you know about” and just not confident in a press fit. My wife calls it “the Osman overkill” It’s hereditary - I got it from my dad.

Now I just need to round up some two liter soda bottles and caps. I don’t use them anymore.

I can save you one or two.

Thanks. A couple with caps would be great.

I can drop this one off tomorrow afternoon if you like.

All I really need are the bottles and caps. Can’t is the bowls for this. Thanks
