According to what I've read, this should work. Any hints to as why it doesn't? It's an ocean beach map, so there is no native usable water.

FILTHY SPAMMER.  TO THE PIT WITH YE.

dont click the damn links, im reporting it now.

Back to the OP,  Ive looked at the forums a bit and the general consenus about desal is everything works and nothing works.  Some people are getting screw pumps to work, sometimes they dont, then do for no reason after a while.  Reports also speak of wells placed straight on the ocean being drunk out of, but still filling buckets with salt water.  Id just dig down to the caverns for water.

  Anybody who has done the dwarvern science with the current version of DF who would like to give some verified info would be most appreciated

I constantly embark on Ocean biomes. I have never desalinated water. I have never had to. Dwarves happily drink from the well when neccesary. Hospital patients are not harmed by it. It acts just like water you would find in any other biome. And my wells plunge straight into the ocean.

Could be that Dwarf kidneys are better at concentrating salts than humans so they are able to drink sea water.

Fun physiology fact:  desert rats can survive by drinking seawater because its kidney can concentrate sodium far more efficiently than the human kidney

I'm also working in an ocean biome right now and having some problems.  A pit that I dug early on to get fresh water worked fine.  Its just a hollowed out and paved ditch outside next to the ocean, about two tiles away from the actual shoreline.  Ofttimes salty mist from ocean waves even lands in it, but dwarfs have been drinking out of it for years with no problem.  Once the ambushes started up I built a larger, more secure pond underground made entirely out of constructed blocks and pumped it full, but to my disappointment it turned out to be saltwater.  Some information...

-Seaside Pond works fine, it is "Outside Light Above Ground"
-Underground Pond is saltwater, it is "Inside Dark Subterranean"
-Seaside Pond is in a biome with no aquifer
-Underground Pond's biome has an aquifer, and is in fact filled with aquifer water

Those two things are the only differences I was able to think of between the two ponds.  And for now I am feeling like the problem lies somewhere in my salty pond being in an aquifer biome.  So OP, are you working with an aquifer or without?  I also want to get down to the bottom of this.  I think that I will build some wells now and see if that changes anything.

[Boogeyman]

Yes there are aquifers present. I also tried to make a small hole to gather rainwater, but it doesn't fill up.

I've yet to try out with wells into the saltwaters.

Try dumping all the water. Draining it completely. And then starting it again, but dont drain it out automatically.And put a well over your water collection area. I've done it fine, but theres clearly unseen forces acting here.

I have something new now after building the well in the Underground Pond.  A dwarf took the Give Water job and fetched a bucket of 'water laced with salt' from the well and brought it to a wounded soldier in the hospital.  The soldier drank it down and was no longer thirsty.  So I suppose that this pond isn't exactly worthless after all.

this will unfortunately only work on ponds that have the murky pool floor tiles.  dwarf made ponds won't fill up, unless it's built around a preexisting pond
