How do I give my injured dwarf water?
1. I've got a well
2. I've got empty buckets
3. I have practically all my dwarfs with "Healthcare" on.
He is injured on his right lower arm, and it says he is Unconcious. He doesn't have the the words Thirsty in his wounds menu anymore.
My question is, I don't have a hospital or any doctors, will a dwarf with the "Healthcare" labour on grab a bucket and give him some water? or do I need to assign or click something?
If it doesn't show that he's Thirsty, I suppose you've already given him water.
Health care usually just happens. If you don't have a hospital, a Dwarf will rest in their own bed (or not at all, sometimes. I've had injured Dwarves ignore injury until I finish my hospital, at which point they suddenly rush off to rest). If they don't have their own bed, they might choose one at random (or, again, not at all).
Any Dwarf with the Feed Patients/Prisoners labor might grab a bucket and go help them all on their own, but it's a slightly low-priority job so sometimes it takes them a little while.
Careful of lye production, as it tends to eat up your empty buckets until you do some crazy work-around or start up a milking industry.
Does walking through a brook clean a dwarf?
What makes me wonder is due to the fact that dwarves don't actually get wet when walking over a brook tile...
The top of the brook is actually a sort of floor. It can be removed with the "channel" designation. In fact, you
have to channel your brook out in order to set up water wheels on it. I suppose if you do this for the entire brook then you'd need to then channel ramps to get in and out of it. Then your Dwarves could get wet, get clean, and drown because they're terrible swimmers. Or get eaten by crocodiles. Or carp. Or suddenly get frozen into blocks of ice when the river freezes.
