Not OP and not in a commune, but they might have a similar setup as a rural naturist resort I am a member at. Well water with a storage tank and filtration system, septic tanks, and for trash either a dumpster that gets emptied by a county garbage collection truck every now and then, or just toss the garbage bags in the back of a pickup truck and drive them to the county dump.

OP mentioned wifi in all the buildings so it's safe to say they're not fully off-grid

Amtrak here in the states has showers on some lines. I'm planning on doing the Texas Eagle from Dallas to Chicago sometime, and they advertise public showers on the trains available to anyone (not just so sleeper room holders).

Roombas? Are you referring to those mobile cat thrones? ;)

Is synthetic bone grafting to prevent loss of teeth due to periodontal disease a good treatment or a scam? It was extremely expensive and I'm told that my teeth may still fall out due to reabsorbtion later on (not guaranteed, but a possibility). Just curious on your opinion of that procedure.
