Yes I also think static water would be a really good compromise for now. I like the idea to habe a bunch oft bucket types, e.g. al little bucket for only 10l water, a really big one for 35l and a tanker for much more water. In my opineon, one of the most important things will also be a pump.
I strongly agree here. I suggested this earlier, yet feel it slipped off into the past somewhere that I'm over-joyed you're bringing this back. We need various sorts of water containers for both thirst & to deal with cooking & crafting other stuff that needs water. Having various things to store water would also be a lovely asset to Rising World, especially when diseases & such shall play a big part in this game (Red51 teased he wanted such).
Coconut liquid containers (milk within at first to then put in water), water bottles (plastic & glass), cups, mugs, wooden wine containers, among various other sorts. Even found out that avocado shells can contain water within if you cut it directly in half. There's various ways to hold water that Red51 shouldn't have any problems or excuses as to not tend to thirst with storage issues
The issue would then be with 'purifying' the water to be drinkable which should be easily fixed if you use moss for the Medieval era (or fruits & veggies), or going with a purifying stick for 'modern' era. There's even industrial-grade gadgets to purify polluted water (not sewage context, yet water in general) so that should be fun to survive in within Rising World. Found this out when people whined of 'water shortages' that's a faux scare.
