In Wurm you only have water down at sea level.
You never find it flowing from higher elevations, and you can only get wells/fountains if you "detect" it above sea level.
You can't divert water to somewhere else as it does not flow.
I remember seeing this game on Indiegogo earlier but that isn't a site I usually think of. Perhaps when you get this out with a more developed alpha/beta you can do a second fund raiser on Kickstarter, like how The Repopulation had two campaigns and I think some other game, perhaps Novus AEterno, had one too.
