Since the below steps will involve a tremendous amount of job cancellations that require pausing and un-suspending construction, designate a meeting zone directly above the dig site to ensure a steady and close supply of free dwarves to respond each time. Now is also a good time to enable Pump Operating (under Engineering) on as many dwarves as possible to ensure steady water pumping. | Since the below steps will involve a tremendous amount of job cancellations that require pausing and un-suspending construction, designate a meeting zone directly above the dig site to ensure a steady and close supply of free dwarves to respond each time.

They only differ in a down vs. up/down staircase and constructed vs. natural walls or stairs. The procedure from now is the same for both of them. Since multi-level aquifers are more [[Fun]], we will use the latter one for the rest of this tutorial. | They only differ in a down vs. up/down staircase and constructed vs. natural walls or stairs.

Yet every time your carpenters or masons get the chance to touch the wall, its construction will proceed a little bit and will be done eventually. Just be patient and keep unsuspending the work.

Congratulations to your 4×2 hole through the aquifer. Be very careful not to mine the first non-aquifer layer any wider than your secured staircase dimensions. The aquifer above this level would flood it. Leave at least one layer of stone between your aquifer and the layer where you want some spacy rooms. | Congratulations to your 4×2 hole through the aquifer.
