Ah, phew. Thought I'd missed something essential there. I just started a new fort in a freezing biome and luckily chose to strike the earth right next to a magma pipe, which is right next to the brook, so in the first 2 seasons I got a magma dump trap ready for those pesky orcs, if they even decide to come this far north.

Really? It wouldn't let me build it unless it was on top of some solid ground... maybe I missed something. I'll go deconstruct and try again, thanks.

I have a magma incineration chamber to deal with pesky orcs. It works very nicely until it's full, then I empty it (via holes under retractable bridges) but the tiles the bridges are anchored to hold a 1/7 tile of magma which must evaporate before anyone else can or will walk through the chamber. Is there any way to adjust the setup so that I can pull a lever and have the whole chamber nicely cleared of magma?

Well I think I might try some stuff out. Looking to make this fort my big one, where I settle down. It's got flux, magma, a brook, plenty of soil and rock, no bauxite yet though I'm in chalk and I think I can find bauxite there.

I'll probably mod something in if I can't find bauxite. I'll make a post if I find anything to contradict or modify the existing water/magma theories.

Yeah I will. Would you believe it I'm still being sieged? I'll give it a go without walls and see how effective it is. Might build a replica tower to compare it with magma too. Might be interesting to have magma spilling out all over the place although my guess is, as it flows slower, there'd be less leakage (assuming there's any with water).

Maybe I'm doing it wrong but my masons take ages to build anything. I have a stockpile at the bottom of the up/down stair scaffold but they still take forever. I'll try it without walls and see how it goes.

Sorry, I searched but couldn't find. I'd test but I'm currently in a fairly drawn out siege.

My question concerns pump stacks. Do I need to surround the pump stack with walls to prevent any water/magma spilling? Or will the pumps just naked on the side of a tower do the job happily?

Also, does mist consume any of the water that generates it? And, if the pumps will pump water upwards without containment, what if the power drops off? Will I get water dropping down from wherever it is on the stack?

I know that water flow can push things. Can it raise things? The reason I ask is that I'm planning an elaborate drowning chamber looking something like this:

%% |
W | |  ____
_ |___|

That's a poor side view. The W is the water source, %% is a pump pumping -> way and the ___ is the chamber. I'm gonna block the pipe with a hatch and open it when I want to flood the chamber. The water should then flow upwards from the floor (as opposed to the less convoluted 'through the wall' approach). It should flood as the chamber's on a lower level than the pump's output tile so hydrostatic water pressure should push it upwards. The question is, what if an unsuspecting orc stands on the hatch? Will it fall to the bottom of the pipe or will it be pushed upwards thanks to the water pressure? I would test this but due to a recent orc siege and a little gap in my power unit, I'm not rolling in dwarfpower to build it.

As a side note I know 7/7 water applies no force but the hatch square on the level of the drowning chamber, as far as I know, shouldn't have 7/7 water on it when the hatch opens. Unless chambers flood 7 units at a time... Can orcs swim?
