Dealing with aquifers
« on: October 24, 2010, 08:41:53 pm »

I was working on some magma pipes for my volcano fortress when I got a "wet stone" warning, and discovered that I had hit an aquifer. The aquifer is located right where I need my pipes, and extends several z levels upward and downward, blocking my attempts at draining it until I could fill it. Is there any way I could get the aquifer to stop producing water so that I could get a dwarf in and wall off the leaks?

Nope.

Unfortunately, you'll need to use either a lot of natural ground, or a lot of pumps. If it extends "several levels," I'd say it's really not worth the effort.

I guess I'll have to look for another volcano then. Oh well, thanks for the help, I would've wasted a lot more time trying to fix it.

You're lucky you're on an embark with a volcano. Cast Obsidian can clear /MANY/ levels of aquifer, but is quite hard to do.

I do it by channeling a large square out untill it hits the first level of the aquifer. (Make sure this square is MASSIVE. I tend to try for 10x10, but it should work on smaller squares.)
Channel down untill you hit water. Pour in magma. Channel down leaving one wall of obsidian behind as to not reopen the aquifer, and pour magma in again.
Should be repeatable in the shape of a reverse pyramid... And incase you're wondering, you don't have to make it smaller each level, just on the aquifer levels.

So THIS is how migrations start.

"Outside" exposure during winter might work if your biome's water freezes during winter.
Also you could drop in rings of normal stone if magma casting does not work.

Engraved on the monitor is an exceptionally designed image of FPS in Dwarf Fortress and it's multicore support by Toady. Toady is raising the multicore. The artwork relates to the masterful multicore support by Toady for the Dwarf Fortress in midwinter of 2010. Toady is surrounded by dwarves. The dwarves are rejoicing.

well you could drypump the borderarea to the aquifier and keep digging + smooting a way through^^ or use the cavein method (see wiki or search the related thread in here for pics)

Easiest way if you have a little stone and wood available is the pump and smooth method. Takes very little time and is very simple if you understand the concept. The cave-in method is okay if you understand it but far more time consuming and more difficult.

Just dig down, pump out the water while you smooth the walls and repeat until you're through the aquifier.

The orange things are stairwells, the blue is water that you're pumping, and the brown lines are the walls you need to smooth. It's a side view of three z-levels (the top being ground).
