[[File:Double-slit-name.png‎|frame|right|The two name-giving slits are highlighted]]

QuantumMenace has developed a very easy method how to dig through an [[DF2012:Aquifer|aquifer]] of an unknown depth commonly known as the '''double-slit method'''. Its name derives from two channeled-out slits at the sides of a 2&times;2 area.

The slits are used to break into the aquifer layer below, hence their ramps are flooded (blue). Water can be pumped from one slit to another slightly faster than the aquifer is flooding it. While a dwarf operates the pump, another dwarf can access the source slit via the ramp and seal off the surrounding walls of the aquifer one by one.

== Draining an aquifer ==

Before we will have a look at the double-slit method itself, it is good to know these basic things about the aquifers and how to drain them.

Aquifers produce infinite amounts of water, but they can also absorb infinite amounts of it. We can drain an aquifer into itself either within one z-level or across multiple z-levels. 

=== Draining across multiple z-levels ===

QuantumMenace's double slit method uses this kind of aquifer draining for all but the lowest aquifer level. Once one of the lower aquifer levels has been cracked open, it can absorb all of the water being produced by the aquifer level above it. 

{|class="wikitable1"
|-valign="top" 
| [[Image:Aquifer draining.png|left|350px|]]
|}

=== Drain within one z-level ===

The double-slit method uses this for the lowest aquifer level. Here we pump out the water from a tile being flooded by the aquifer to the level above it (which is already secured) and let it flow back down to another tile where it becomes absorbed by the same aquifer layer again. Note that the target tile of the aquifer must be cracked open (e.g. by downstairs or a channel) to be able to receive water.

{|class="wikitable1" style="padding-top: 2em"
|-valign="top" 
| [[Image:Aquifer_pump_scheme.png|left|600px|Water flow between the two slits.]]
|}

== Tutorial embark setup ==
The double-slit method will be presented in a form of a play-along tutorial. Train it on an embark which you don't intend to play after you've made it through the aquifer. Try to embark at some forested place near the ocean where multi-level aquifers are almost guaranteed. Take this embark setup:

* 1 Proficient Miner
* 4 Proficient Carpenters
* 2 Proficient Wood cutter

You can sell the anvil, one pick, and all quivers, splints and crutches to buy loads of wooden logs. It will save you time cutting down trees.

Make sure you have at least one (battle) axe and one 1 pick to cut down trees and mine.

== Procedure ==

=== Preparation ===

Using your logs of wood, build a carpenter's workshop and craft all the parts necessary to build a pump, i.e.:

* a [[DF2012:Block|block]]<br />
* an [[Trap_components#Enormous_corkscrew|enormous corkscrew]]
* a [[DF2012:Pipe section|pipe section]]

==== Find out what you are dealing with  ====

===== Access the aquifer =====

Dig a 2&times;2 staircase down to the aquifer

{|class="wikitable1"
|-valign="top" 
| [[Image:Safe-layer.png‎|frame|left|Your last non-aquifer layer]]
| [[Image:Aq01.png‎|frame|left|Your first aquifer layer]]
|}

===== Check whether there is more than one level of the aquifer =====

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq02.png‎‎|frame|left|Dig downstairs next to your 2&times;2 stairs.]]
| [[Image:Aq03.png‎|frame|left|Dig up/down stairs into the aquifer below.]]
|}

When digging the up/down stair into the aquifer, better pause the game and use {{K|.}} One-Step to see the revealed tile below the first aquifer level before it gets flooded.

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq04.png‎‎|frame|left|The up/down stairs have just been dug and are not yet flooded.]]
| [[Image:Aq05.png‎|frame|left|Check the description of the tile revealed below them.]]
|}

If it says "Damp X" (X is the name of the stone/soil), it is another aquifer level and we proceed dealing with the upper aquifer levels. If it is regular stone (not damp), we will be dealing with the lowest aquifer level.

=== Dealing with the upper aquifer levels ===

We want to drain one level of the aquifer into another further below.

==== Drain the upper aquifer level to the lower one ====

We need access to the lower aquifer level and crack it open.

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq06.png‎|frame|left|Dig down stairs left and right of your 2&times;2 stairs.]]
| [[Image:Aq07.png‎|frame|left|Dig up/down stairs into the aquifer level below. They will quickly become flooded.]]
|}

Now we will pump the water from one slit into the other. A pump can only be placed on a floor, not a staircase.

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq08.png‎|frame|left|Construct two floor tiles instead of two up/down stairs between the slits.]]
| [[Image:Aq09.png‎|frame|left|Build a screw pump there (e.g. pumping from the west).]]
|}

Unfortunately, this pump won't work if there is stairs in its source tile.

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq10.png‎|frame|left|Remove the downstairs from the source file (channel it out).]]
| [[Image:Aq11.png‎|frame|left|Start pumping.]]
|-valign="top" 
| [[Image:Aq12.png‎|frame|left|Now your miner can access the stairs previously flooded.]]
| [[Image:Aq13.png‎|frame|left|Mine two up/downstairs into the lower aquifer level.]]
|}

Here, too, you can {{K|.}} one-step to peek under the second layer of your aquifer. Once the up/down stairs are dug, disassemble the pump, turn it to the other direction and dig more stair there. (Don't forget to channel out the downstairs in the pump's source tile.) You should end up with something like this:

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq14.png‎|frame|left|Lowest non-aquifer level (or a secured aquifer level)]]
| [[Image:Aq15.png‎|frame|left|First aquifer level (being drained into the level below)]]
|-valign="top" 
| [[Image:Aq16.png‎|frame|left|Second aquifer level (receiving aquifer water from above)]]
| [[Image:Aq17.png‎|frame|left|The level below the second aquifer level]]
|}

Now you can stop and dismantle the pump. The upper aquifer level is being drained into the lower one and is accessible without the help of a pump.

==== Secure the upper aquifer level ====

You can now secure the upper aquifer level by cautiously walling it off. The procedure described here takes about one in-game month per level of aquifer. It involves building walls to seal the aquifer off. To build walls more quickly, build them out of [[block]]s, rather than stone or wood. To get the least amount of job cancellations, build them in the order suggested here.

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq18.png‎|frame|left|Dig the aquifer tiles to the north and south of the slits.]]
| [[Image:Aq19.png‎|frame|left|Build walls there.]]
|-valign="top" 
| [[Image:Aq20.png‎|frame|left|Dig and build walls here.]]
| [[Image:Aq21.png‎|frame|left|Dig and build walls here.]]
|}

Now the water from the aquifer will start to push your miners and workers around, so better be careful and to this step by step. Expect some job cancellations. You can minimize them by building out of blocks (e.g. wood blocks) rather than normal logs (or stone):

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq22.png‎|frame|left|Dig one staircase.]]
| [[Image:Aq23.png‎|frame|left|Dig one wall.]]
|-valign="top" 
| [[Image:Aq24.png‎|frame|left|Build one wall.]]
| [[Image:Aq25.png‎|frame|left|Proceed until you have this.]]
|}

Now you have secured one level of the aquifer. If there are at least two other levels below this one, you can repeat the procedure described in [[#Dealing with the upper aquifer levels|Dealing with the upper aquifer levels]]. Else, follow the procedure described in [[#Dealing with the lowest aquifer level|Dealing with the lowest aquifer level]].

=== Dealing with the lowest aquifer level ===

If you have come here after you've been drilling through several aquifer levels above, your starting point looks like this:

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq25.png‎|frame|left|Secured level above the lowest aquifer layer]]
|}

Or you were just lucky and have encountered only a one-level aquifer. In that case you are starting with this:

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq26.png‎|frame|left|Secured level above the lowest aquifer layer]]
|}

In any case, we must now prepare our grounds for pumping the last aquifer level from one slit to another. 

==== Preparing the grounds ====

If your slits aren't filled with nothing but stairs, this is really easy:

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq27.png‎|frame|left|Dig three channels and build floors for a pump.]]
| [[Image:Aq28.png‎|frame|left|Build a pump pumping from the west.]]
|}

Once you have this, you can proceed with [[#Walling off the last aquifer level|Walling off the last aquifer level]]

If, however, your slits are filled with nothing but up/down stairs, things become more complicated. Pumps cannot pump from a source tile which has stairs. Yet you must keep both slits accessible for your dwarves. 

==== Walling off the last aquifer level ====

[[Category:DF2012:Guides]]


= Junk =

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

1. Make yourself an access to the aquifer layer:

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq02.png‎|frame|left|1. Channel out one tile at each side of your staircase like this.]]
| [[Image:Aq03.png‎|frame|left|2. This is how the aquifer level looks now.]]
|-valign="top" 
| [[Image:Aq04.png|frame|left|3. Build a floor replacing the stairs between the channels.]]
| [[Image:Aq05.png|frame|left|4. Build a pump there, pumping from the west (make sure one of your dwarves has the [[DF2012:Building designer|architecture]] labor enabled).]]
|}

2. Make sure you have at least one dwarf with the [[DF2012:Pump_operator|pump operating]] labor enabled. Start pumping the water from one side to another. And build walls around the first quadrant.

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq06.png|frame|left|1. Designate these two tiles to be dug]]
| [[Image:Aq07.png|frame|left|2. First build the wall on the south (expect a lot of cancellation spam).]]
|-valign="top" 
| [[Image:Aq08.png|frame|left|3. Then the wall on the north]]
| [[Image:Aq09.png|frame|left|4. Then these two walls (build them one by one).]]
|}

3. Deconstruct the water pump, build it facing the other direction and start pumping again. Build walls around the second quadrant accordingly.

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq10.png|frame|left|1. Start with the southern one]]
| [[Image:Aq11.png|frame|left|2. Proceed until you achieve this]]
|}

4. Deconstruct the pump and the floor tiles in your non-aquifer layer and construct an up/down staircase there instead.

{|class="wikitable1"
|-valign="top" 
| [[Image:Aq12.png|frame|left|1. Pump and floor deconstructed]]
| [[Image:Aq13.png|frame|left|2. Stairs built]]
|}

5. The procedure for building walls in the third quadrant differs slightly from what you have been building until now.

{|class="wikitable1"
|-valign="top" 
|[[Image:Aq14.png|frame|left|1. Dig a channel to the left and right and build a water pump between them (e.g. pumping from the east) and start pumping.]]
|[[Image:Aq15.png|frame|left|2. Don't dig under your stairs. Instead, build a wall in place of the south-eastern channel tile.]]
|-valign="top" 
|[[Image:Aq16.png|frame|left|3. Continue walling off the the third quadrant by building this wall in the north.]]
|[[Image:Aq17.png|frame|left|4. Proceed building in until it looks like this. You mustn't dig the wall under the stairs. It will serve us as water sink.]]
|}


6. Now for the last quadrant. We deliberately haven't dug the North-East wall under the stairs. Despite it being aquifer and leaking water, we need it to use it as a water sink now. Remember, aquifers can receive infinite amount of water, too. Deconstruct the pump and build it to pump to the opposite direction. It will spill some water on its level while pumping, but it isn't dangerous.

{|class="wikitable1"
|-valign="top" 
|[[Image:Aq18.png|frame|left|1. Designate these two aquifer walls to be dug.]]
|[[Image:Aq19.png|frame|left|2. Proceed with the northern wall.]]
|-valign="top" 
|[[Image:Aq20.png|frame|left|3. Then bulid these other three walls.]]
|[[Image:Aq24.png|frame|left|4. Deconstruct the pump and the floors and construct Up/Down stairs there.]]
|}

7. We will now deal with the last piece of aquifer. 

{|class="wikitable1"
|-valign="top" 
|[[Image:Aq21.png|frame|left|1. Deconstruct the wall marked with the "C" to gain access to the last aquifer tile. Aquifers don't leak diagonally, so we are safe here.]]
|[[Image:Aq22.png|frame|left|2. Mine the last piece of the aquifer on this level.]]
|-valign="top" 
|[[Image:Aq23.png|frame|left|3. It will produce 7 units of water wetting the ground a bit.]]
|[[Image:Aq25.png|frame|left|4. Dig downstairs to check whether there is another aquifer layer below.]]
|}

When you are digging the downstairs, better have the game paused and proceed step by step ({{K|.}} One-Step). There is usually some water on the level where you are digging from, which would immediately run down the stairs you're digging and make the level below damp. The only way to tell whether there is an aquifer below is to stop the at the very moment when your miner reveals the first tile of it. If it is damp before the water from your level has run down on it, it is another aquifer level.

{|class="wikitable1"
|-valign="top" 
|[[Image:Aq26.png|frame|left|5. Construct up/down stairs on top of the downstairs to have an access to this level once the ramps are removed.]]
|[[Image:Aq27.png|frame|left|6. Deconstruct the redundant walls.]]
|}

8. Level done

{|class="wikitable1"
|-valign="top" 
|[[Image:Aq28.png|frame|left|Enjoy your first secured aquifer layer.]]
|}

If you see there is another aquifer layer below, you repeat the steps in sections 1-8. To dig through one layer of aquifer this way will take you 2 or 3 months in-game time.

+Here, too, you can {{K|.}} one-step to peek under the second layer of your aquifer. Once the up/down stairs are dug, disassemble the pump, turn it to the other direction and dig more stair there. (Don't forget to channel out the downstairs in the pump's source tile.) You should end up with something like this:

+You can now secure the upper aquifer level by cautiously walling it off. The procedure described here takes about one in-game month per level of aquifer. It involves building walls to seal the aquifer off. To build walls more quickly, build them out of [[block]]s, rather than stone or wood. To get the least amount of job cancellations, build them in the order suggested here.

+Now the water from the aquifer will start to push your miners and workers around, so better be careful and to this step by step. Expect some job cancellations. You can minimize them by building out of blocks (e.g. wood blocks) rather than normal logs (or stone):

+Now you have secured one level of the aquifer.

+=== Dealing with the lowest aquifer level ===
+If you have come here after you've been drilling through several aquifer levels above, your starting point looks like this:
+{|class="wikitable1"
+|-valign="top"
+| [[Image:Aq25.png‎|frame|left|Secured level above the lowest aquifer layer]]
+|}
+Or you were just lucky and have encountered only a one-level aquifer. In that case you are starting with this:
+{|class="wikitable1"
+|-valign="top"
+| [[Image:Aq26.png‎|frame|left|Secured level above the lowest aquifer layer]]
+|}
+In any case, we must now prepare our grounds for pumping the last aquifer level from one slit to another.
+==== Preparing the grounds ====
+If your slits aren't filled with nothing but stairs, this is really easy:
+{|class="wikitable1"
+|-valign="top"
+| [[Image:Aq27.png‎|frame|left|Dig three channels and build floors for a pump.]]
+| [[Image:Aq28.png‎|frame|left|Build a pump pumping from the west.]]
+|}
+Once you have this, you can proceed with [[#Walling off the last aquifer level|Walling off the last aquifer level]]
+If, however, your slits are filled with nothing but up/down stairs, things become more complicated. Pumps cannot pump from a source tile which has stairs. Yet you must keep both slits accessible for your dwarves.

+|}
+. Make sure you have at least one dwarf with the [[DF2012:Pump_operator|pump operating]] labor enabled. Start pumping the water from one side to another. And build walls around the first quadrant.
+{|class="wikitable1"

+| [[Image:Aq09.png|frame|left|4. Then these two walls (build them one by one).]]
+|}
+. Deconstruct the water pump, build it facing the other direction and start pumping again. Build walls around the second quadrant accordingly.
+{|class="wikitable1"

+| [[Image:Aq10.png|frame|left|1. Start with the southern one]]
+| [[Image:Aq11.png|frame|left|2. Proceed until you achieve this]]

+| [[Image:Aq12.png|frame|left|1. Pump and floor deconstructed]]
+| [[Image:Aq13.png|frame|left|2. Stairs built]]

+. The procedure for building walls in the third quadrant differs slightly from what you have been building until now.
+{|class="wikitable1"
+|-valign="top"
+|[[Image:Aq14.png|frame|left|1. Dig a channel to the left and right and build a water pump between them (e.g. pumping from the east) and start pumping.]]

+|-valign="top"
+|[[Image:Aq16.png|frame|left|3. Continue walling off the the third quadrant by building this wall in the north.]]
+|[[Image:Aq17.png|frame|left|4. Proceed building in until it looks like this. You mustn't dig the wall under the stairs. It will serve us as water sink.]]
+|}
+. Now for the last quadrant. We deliberately haven't dug the North-East wall under the stairs. Despite it being aquifer and leaking water, we need it to use it as a water sink now. Remember, aquifers can receive infinite amount of water, too. Deconstruct the pump and build it to pump to the opposite direction. It will spill some water on its level while pumping, but it isn't dangerous.
+{|class="wikitable1"
+|-valign="top"
+|[[Image:Aq18.png|frame|left|1. Designate these two aquifer walls to be dug.]]

+{|class="wikitable1"
+|-valign="top"
+|[[Image:Aq21.png|frame|left|1. Deconstruct the wall marked with the "C" to gain access to the last aquifer tile. Aquifers don't leak diagonally, so we are safe here.]]

+|[[Image:Aq25.png|frame|left|4. Dig downstairs to check whether there is another aquifer layer below.]]
+|}
+When you are digging the downstairs, better have the game paused and proceed step by step ({{K|.}} One-Step). There is usually some water on the level where you are digging from, which would immediately run down the stairs you're digging and make the level below damp. The only way to tell whether there is an aquifer below is to stop the at the very moment when your miner reveals the first tile of it. If it is damp before the water from your level has run down on it, it is another aquifer level.

-=== Stockpile of Cages ===
+If you see there is another aquifer layer below, you repeat the steps in sections 1-8. To dig through one layer of aquifer this way will take you 2 or 3 months in-game time.
