&lt;div&gt;== The Repeater ==&lt;br /&gt;
&lt;br /&gt;
Actually there ARE faster versions of this - that's 2 or more desynchronized repeaters. --[[User:Digger|Digger]] 05:33, 1 March 2008 (EST)&lt;br /&gt;

Can anyone else get the repeater to work without using masterpiece mechanisms in the pressure plates?  I can't, so I'm assuming you need masterpiece mechanisms.  Too bad I don't have a mechanic capable of that yet &amp;gt;_&amp;lt; --[[User:Sukasa|Sukasa]] 23:07, 5 April 2008 (EDT)&lt;br /&gt;

Re: The Memory setup.&lt;br /&gt;
&lt;br /&gt;
In the current example; You can't actually build it. It took me a bit of thinking and working, but I managed to make a system that efficiently (as far as I could tell) used space to make memory switches or registers, depending on what you want to call them.&lt;br /&gt;
&lt;br /&gt;
Start with:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;

&lt;br /&gt;
While you're in the Mining mood, go down a z-level and clear out AT LEAST this one z level lower:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
################&lt;br /&gt;

###.#.###.#.####&lt;br /&gt;
################&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Note that this is the minimum required; If you're using a large pool you'll need more to make sure you don't flood your mechanism level.&lt;br /&gt;
&lt;br /&gt;
Place hatches on all the channels EXCEPT the far left and far right triple channels. Place axles, gears, and Pressure Plates so you end up with:&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
################&lt;br /&gt;

&lt;br /&gt;
Finally, put waterwheels over the channels, hung off of the axles. You *should* be able to figure out where the pumps should go, but remember to link your hatches and pressure plates BEFORE building the pumps, because you won't be able to reach them again without digging another stair. To get the water to flow, you just dig out that wall between the water wheel and the pool by digging a channel one z above it. I'm not *sure*, but you may need to put a second or third water wheel inline with the first one for this to actually provide you enough power. STILL, this setup gives you a grand total of 8 memory registers, plenty to do whatever you want with whatever devious traps you have in mind. (I use it to operate bridges over magma channels.)

Should nuggets be labelled as such in the list? Before they are mined they are referred to as 'Native &amp;lt;metalname&amp;gt;', and are only labelled as nuggets once mined. Perhaps the table should be changed to indicate this. --[[User:TangoThree|TangoThree]] 09:14, 20 January 2008 (EST)&lt;br /&gt;

&lt;div&gt;Toady mentioned somewhere that, at the moment, only subterrainian water sources can grow towercaps. He then explicitly mentioned underground rivers and lakes, but would an aquifer work as well? If so, given the scarcity of underground water sources, this would provide another bonus to having an aquifer.[[User:Thexor|Thexor]] 20:10, 31 October 2007 (EDT)&lt;br /&gt;

&lt;br /&gt;
== My plan for dealing with an aquifer ==&lt;br /&gt;
&lt;br /&gt;
The DF Map Archive has never worked for me, so I was unable to make use of the link to the example.&lt;br /&gt;
Also, I was playing on a map entirely covered in a layer of aquifer, so I couldn't mine any stone for mechanism purposes.&lt;br /&gt;
Fortunately, I had tons and tons of wood (if you're gonna be on an aquifer map, you might as well get a heavily forested one)&lt;br /&gt;
I discovered that because of the way mechanical buildings are handled, you can use a pump as a pretty reasonable surrogate for gear assemblies - and currently, you don't need stone to make pumps, because wood blocks can be used in place of stone blocks.&lt;br /&gt;
&lt;br /&gt;
So, here's how I dealt with the aquifer:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
          &lt;br /&gt;
Legend: &lt;br /&gt;
&lt;br /&gt;
  |&lt;br /&gt;
^,V,&amp;lt;-,-&amp;gt;: Pumps, oriented to pump from dash to &amp;quot;arrow&amp;quot; point for clarity&lt;br /&gt;
|&lt;br /&gt;
w: water-filled channel&lt;br /&gt;
&amp;gt;: down stairway&lt;br /&gt;
&amp;lt;: up stairway&lt;br /&gt;
X: up/down stairway&lt;br /&gt;
=,ǁ: horizontal axles&lt;br /&gt;
#: normal walls&lt;br /&gt;
*: banks of waterwheels (with channels dug under them, of course. &lt;br /&gt;
Build the horizontal axle first so they'll hang off it)&lt;br /&gt;
&lt;br /&gt;
A note: the amount of effort it takes to wall off a square with this method &lt;br /&gt;
is pretty much constant with regard to size, which means that it's better to build a great&lt;br /&gt;
big aquifer-free area and not need most of it than to build a small one and realize you're &lt;br /&gt;
gonna have to expand it. Also, great big ridiculous projects are more fun!&lt;br /&gt;
&lt;br /&gt;
So, to build one wall of the new floor (I ended up doing both parallel walls at the same time):&lt;br /&gt;
&lt;br /&gt;
##########################&lt;br /&gt;
#.wwww&amp;gt;..................#&lt;br /&gt;

#.w&amp;lt;-ww-&amp;gt;w...............#&lt;br /&gt;
#.w&amp;lt;-ww-&amp;gt;w...............#&lt;br /&gt;
.... repeat until you will be clearing out enough space.&lt;br /&gt;
#.w&amp;lt;-ww-&amp;gt;w...............#&lt;br /&gt;
#.w&amp;lt;-ww-&amp;gt;w...............#&lt;br /&gt;

#.***................***.#     Also, they're what keeps the waterwheel from collapsing&lt;br /&gt;
#.***................***.#&lt;br /&gt;
#.***................***.#&lt;br /&gt;
##########################&lt;br /&gt;
&lt;br /&gt;
You can easily add more waterwheels to the south if you need moar powah.&lt;br /&gt;
If they haven't started yet, you can prime the waterwheels by running &lt;br /&gt;
one of the pumps manually for a few seconds.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Going from left to right (again, I did the two parallel walls here simultaneously):&lt;br /&gt;
&lt;br /&gt;
##########################&lt;br /&gt;
#........................#&lt;br /&gt;

##########################&lt;br /&gt;
&lt;br /&gt;
Note that when you rotate 90 degrees and start working on the new walls, you'll almost &lt;br /&gt;
certainly have to re-floor some aquifer channels.&lt;br /&gt;
&lt;br /&gt;
You'll want to make the inside of the pumped out area look like this:&lt;br /&gt;
&lt;br /&gt;
 ###&lt;br /&gt;
##&amp;lt;#&lt;br /&gt;
#++#&lt;br /&gt;
#+X#&lt;br /&gt;
#+.#&lt;br /&gt;
#+.#&lt;br /&gt;
#+.#&lt;br /&gt;
#+.#&lt;br /&gt;
#+.#&lt;br /&gt;
#+.#&lt;br /&gt;
#+X#&lt;br /&gt;
#++#&lt;br /&gt;
##&amp;lt;#&lt;br /&gt;
 ###&lt;br /&gt;
&lt;br /&gt;
Which means queue up the up/down stairways and the walls on the left side first, then&lt;br /&gt;
the two walls on the right. Water can flow through corners, but dwarves can't build &lt;br /&gt;
through that tight gap. You put in two stairways, one near each end, so that when &lt;br /&gt;
you rotate 90 degrees and do it again in the other direction you'll have a stairway pre-built.&lt;br /&gt;
&lt;br /&gt;
The main benefit of this two-pump system is that, in my experience, it minimizes the&lt;br /&gt;
amount of micromanagement you'll be doing. I found that I only had to unsuspend each&lt;br /&gt;
wall (that is, the entire thing, not individual segments) four or five times before it&lt;br /&gt;
was done, with the most egregious bits being the end walls (which is understandable,&lt;br /&gt;
they've got an unpumped area next to them).&lt;br /&gt;
&lt;br /&gt;
It does leak a very little bit; you should expect splatterings of 1 and 2 depth water all &lt;br /&gt;
over the place. If you see anything deeper over a non-channel square, something's sprung a &lt;br /&gt;
leak and it's time to call in the O-SHID and shut everything down.&lt;br /&gt;
&lt;br /&gt;
Note that your re-walling dwarves will be quite happy most of the time, what with all the &lt;br /&gt;
mist they'll be walking through constantly.&lt;br /&gt;
&lt;br /&gt;
Once you've got a square bit of area blocked off, you'll have to shift a bank of pumps back &lt;br /&gt;
one square, dig out all the remaining aquifer tiles in the center, and pump out the remaining &lt;br /&gt;
water. Then dig downward and hope you don't have to do this again!&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Anyway, I hope this is useful. I didn't put it this on the main article because it's like four AM here. [[User:Tacroy|Tacroy]] 07:33, 14 December 2007 (EST)&lt;br /&gt;

== notes from nov1 version ==&lt;br /&gt;
&lt;br /&gt;
this is a cleaned-up chat log from #bay12games on Nov 01 11:07 (PST).  Pasting it here until the information works its way in to the wiki page.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sinoth&amp;gt; VeryInky: you seem to be the aquifer expert.  have you found a way to get around them without magma?&lt;br /&gt;
&lt;br /&gt;
&amp;lt;VeryInky&amp;gt; [[Pump|Pumps]]. But pumps require stone. If you have access to stone, the aquifer shouldn't be that much of a problem.  The key draining the aquifer square, then building floodgate.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sinoth&amp;gt; so the aquifer has a finite amount of water in it, unlike brooks and rivers?&lt;br /&gt;
&lt;br /&gt;
&amp;lt;VeryInky&amp;gt; Unlimited.  It's an infinite water source.  It's been sort of fixed in the new version, so getting past the aquifer is much easier.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sinoth&amp;gt; what changed to make it easier? don't see it on the dev_notes&lt;br /&gt;
&lt;br /&gt;
&amp;lt;VeryInky&amp;gt; Non dirt squares no longer automatically refill.  IN other words, it's now possible to make a wall and block the aquifer.  So you can build deeper; wasn't possible before.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sinoth&amp;gt; ah ok, thanks much :)&lt;br /&gt;
&lt;br /&gt;
&amp;lt;VeryInky&amp;gt; It's none the less MUCH easier with magma. Dig channels until you reach the aquifer, then divert magma into it. It turns into solid obsidian and you can just continue on.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sinoth&amp;gt; i wasn't aware you could build pumps solely with stone.  don't you need the [[enormous corkscrew|screw thing]], made out of metal or wood?&lt;br /&gt;
&lt;br /&gt;
&amp;lt;VeryInky&amp;gt; Requires a stone, but you can make the screw and pipes out of wood.&lt;br /&gt;

== Unmarked Aquifer? ==&lt;br /&gt;
&lt;br /&gt;
Is it possible to have an aquifer if it was not listed on the pick an area screen? Normally if you are going to enter an area with an aquifer, I have noticed that it shows you with a band of blue at the level that it is located, and the game asks if you are sure you want to settle there. In my case, there was no aquifer listed, and I received no warning, but I cannot go below a layer of yellow sand without hitting Damp Stone (actually it is Damp Loam)&lt;br /&gt;
&lt;br /&gt;
The map does have a river, do you get Aquifer with a river automatically?&lt;br /&gt;
:You only get information on the square that your local area is centered on. Thus you can have an aquifer on part of the map without it being listed. --[[User:Ikkonoishi|Ikkonoishi]] 21:12, 6 November 2007 (EST)&lt;br /&gt;

:Yeah, I had a section of chalk containing an unmarked aquifer in a mostly igneous area.. luckily I was able to just dig around it. [[User:Anydwarf|Anydwarf]] 01:57, 8 November 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
==Stone method==&lt;br /&gt;
&lt;br /&gt;
Some maps have an aquifer that doesn't span all of the map's biomes, in which case the aquifer is easy to avoid by paying attention to where the different biomes are situated.  Is that what this section is referring to, or can there really be &amp;quot;holes&amp;quot; in an aquifer? --[[User:Peristarkawan|Peristarkawan]] 02:46, 3 November 2007 (EDT)&lt;br /&gt;

:I have found rock pockets in an aquifer that were dry.  They are rare and hard to find, when they are there at all.  [[User:Geekwad|Geekwad]] 17:05, 6 November 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
::Rumours on the ofurms are that ore squares don't generate water, so if you can find enough in one place you can dig through them.  I don't know if this is accurate. --[[User:Lacero|Lacero]] 05:46, 8 November 2007 (EST)&lt;br /&gt;

So I read that a cave-in would make the aquifier mineable... Has this changed recently? I setup a cave-in as follows and the water's still flooding. Did I do it wrong?&lt;br /&gt;

I then dug out the * tile and caused the cave-in. The aquifier water is still all at 7 depth,&lt;br /&gt;
even after Bilging (having dwarves fill a pond elsewhere with the water from here)&lt;br /&gt;
was I supposed to hit the walls of the Aquifier level with the cave-in?&amp;lt;/pre&amp;gt; --[[User:CrushU|CrushU]] 10:57, 12 March 2008 (EDT)&lt;br /&gt;
&lt;br /&gt;
:AFAIK, the cave-in method is a bug exploit that you use to change the type of tile. You use the cave in to change the some of the aquifer tiles into non-aquifer tiles and then mine through the center. [[User:VengefulDonut|VengefulDonut]] 11:11, 12 March 2008 (EDT)&lt;br /&gt;
::Thanks, I'll still try it at some point, but I'll pump out water and make walls to go through it mainly.--[[User:CrushU|CrushU]] 11:51, 12 March 2008 (EDT)&lt;br /&gt;

&lt;div&gt;Toady mentioned somewhere that, at the moment, only subterrainian water sources can grow towercaps. He then explicitly mentioned underground rivers and lakes, but would an aquifer work as well? If so, given the scarcity of underground water sources, this would provide another bonus to having an aquifer.[[User:Thexor|Thexor]] 20:10, 31 October 2007 (EDT)&lt;br /&gt;

== My plan for dealing with an aquifer ==&lt;br /&gt;
&lt;br /&gt;
The DF Map Archive has never worked for me, so I was unable to make use of the link to the example.&lt;br /&gt;
Also, I was playing on a map entirely covered in a layer of aquifer, so I couldn't mine any stone for mechanism purposes.&lt;br /&gt;
Fortunately, I had tons and tons of wood (if you're gonna be on an aquifer map, you might as well get a heavily forested one)&lt;br /&gt;
I discovered that because of the way mechanical buildings are handled, you can use a pump as a pretty reasonable surrogate for gear assemblies - and currently, you don't need stone to make pumps, because wood blocks can be used in place of stone blocks.&lt;br /&gt;
&lt;br /&gt;
So, here's how I dealt with the aquifer:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;pre&amp;gt;&lt;br /&gt;
          &lt;br /&gt;
Legend: &lt;br /&gt;
&lt;br /&gt;
  |&lt;br /&gt;
^,V,&amp;lt;-,-&amp;gt;: Pumps, oriented to pump from dash to &amp;quot;arrow&amp;quot; point for clarity&lt;br /&gt;
|&lt;br /&gt;
w: water-filled channel&lt;br /&gt;
&amp;gt;: down stairway&lt;br /&gt;
&amp;lt;: up stairway&lt;br /&gt;
X: up/down stairway&lt;br /&gt;
=,ǁ: horizontal axles&lt;br /&gt;
#: normal walls&lt;br /&gt;
*: banks of waterwheels (with channels dug under them, of course. &lt;br /&gt;
Build the horizontal axle first so they'll hang off it)&lt;br /&gt;
&lt;br /&gt;
A note: the amount of effort it takes to wall off a square with this method &lt;br /&gt;
is pretty much constant with regard to size, which means that it's better to build a great&lt;br /&gt;
big aquifer-free area and not need most of it than to build a small one and realize you're &lt;br /&gt;
gonna have to expand it. Also, great big ridiculous projects are more fun!&lt;br /&gt;
&lt;br /&gt;
So, to build one wall of the new floor (I ended up doing both parallel walls at the same time):&lt;br /&gt;
&lt;br /&gt;
##########################&lt;br /&gt;
#.wwww&amp;gt;..................#&lt;br /&gt;

#.w&amp;lt;-ww-&amp;gt;w...............#&lt;br /&gt;
#.w&amp;lt;-ww-&amp;gt;w...............#&lt;br /&gt;
.... repeat until you will be clearing out enough space.&lt;br /&gt;
#.w&amp;lt;-ww-&amp;gt;w...............#&lt;br /&gt;
#.w&amp;lt;-ww-&amp;gt;w...............#&lt;br /&gt;
#.w&amp;lt;-ww-&amp;gt;w...............#&lt;br /&gt;

#.w^===^==============^..#     &lt;br /&gt;

#.wǁ..................ǁ..# &amp;lt;== These axles are a bit important. I didn't use them once &lt;br /&gt;
#.***wwwwwwwwwwwwwwww***.#     but had north-facing pumps, and nearly flooded the excavation room.&lt;br /&gt;
#.***................***.#     Also, they're what keeps the waterwheel from collapsing&lt;br /&gt;
#.***................***.#&lt;br /&gt;
#.***................***.#&lt;br /&gt;
##########################&lt;br /&gt;
&lt;br /&gt;
You can easily add more waterwheels to the south if you need moar powah.&lt;br /&gt;
If they haven't started yet, you can prime the waterwheels by running &lt;br /&gt;
one of the pumps manually for a few seconds.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Going from left to right (again, I did the two parallel walls here simultaneously):&lt;br /&gt;
&lt;br /&gt;

#.wǁwwwwwwwwwwwwwwwwwww..# &amp;lt;= Even though you can't see it (not even in-game!)&lt;br /&gt;
#.wǁ.....................#    there's channels under the axle here and above. &lt;br /&gt;
#.wǁ.....................#    They're fine just hanging out as long as they're  &lt;br /&gt;

#.***................***.#&lt;br /&gt;
#.***................***.#&lt;br /&gt;
##########################&lt;br /&gt;
&lt;br /&gt;
Note that when you rotate 90 degrees and start working on the new walls, you'll almost &lt;br /&gt;
certainly have to re-floor some aquifer channels.&lt;br /&gt;
&lt;br /&gt;
You'll want to make the inside of the pumped out area look like this:&lt;br /&gt;
&lt;br /&gt;
 ###&lt;br /&gt;
##&amp;lt;#&lt;br /&gt;
#++#&lt;br /&gt;
#+X#&lt;br /&gt;
#+.#&lt;br /&gt;
#+.#&lt;br /&gt;
#+.#&lt;br /&gt;
#+.#&lt;br /&gt;
#+.#&lt;br /&gt;
#+.#&lt;br /&gt;
#+X#&lt;br /&gt;
#++#&lt;br /&gt;
##&amp;lt;#&lt;br /&gt;
 ###&lt;br /&gt;
&lt;br /&gt;
Which means queue up the up/down stairways and the walls on the left side first, then&lt;br /&gt;
the two walls on the right. Water can flow through corners, but dwarves can't build &lt;br /&gt;
through that tight gap. You put in two stairways, one near each end, so that when &lt;br /&gt;
you rotate 90 degrees and do it again in the other direction you'll have a stairway pre-built.&lt;br /&gt;
&lt;br /&gt;
The main benefit of this two-pump system is that, in my experience, it minimizes the&lt;br /&gt;
amount of micromanagement you'll be doing. I found that I only had to unsuspend each&lt;br /&gt;
wall (that is, the entire thing, not individual segments) four or five times before it&lt;br /&gt;
was done, with the most egregious bits being the end walls (which is understandable,&lt;br /&gt;
they've got an unpumped area next to them).&lt;br /&gt;
&lt;br /&gt;
It does leak a very little bit; you should expect splatterings of 1 and 2 depth water all &lt;br /&gt;
over the place. If you see anything deeper over a non-channel square, something's sprung a &lt;br /&gt;
leak and it's time to call in the O-SHID and shut everything down.&lt;br /&gt;
&lt;br /&gt;
Note that your re-walling dwarves will be quite happy most of the time, what with all the &lt;br /&gt;
mist they'll be walking through constantly.&lt;br /&gt;
&lt;br /&gt;
Once you've got a square bit of area blocked off, you'll have to shift a bank of pumps back &lt;br /&gt;
one square, dig out all the remaining aquifer tiles in the center, and pump out the remaining &lt;br /&gt;
water. Then dig downward and hope you don't have to do this again!&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Anyway, I hope this is useful. I didn't put it this on the main article because it's like four AM here. [[User:Tacroy|Tacroy]] 07:33, 14 December 2007 (EST)&lt;br /&gt;

== notes from nov1 version ==&lt;br /&gt;
&lt;br /&gt;
this is a cleaned-up chat log from #bay12games on Nov 01 11:07 (PST).  Pasting it here until the information works its way in to the wiki page.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sinoth&amp;gt; VeryInky: you seem to be the aquifer expert.  have you found a way to get around them without magma?&lt;br /&gt;
&lt;br /&gt;
&amp;lt;VeryInky&amp;gt; [[Pump|Pumps]]. But pumps require stone. If you have access to stone, the aquifer shouldn't be that much of a problem.  The key draining the aquifer square, then building floodgate.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sinoth&amp;gt; so the aquifer has a finite amount of water in it, unlike brooks and rivers?&lt;br /&gt;
&lt;br /&gt;
&amp;lt;VeryInky&amp;gt; Unlimited.  It's an infinite water source.  It's been sort of fixed in the new version, so getting past the aquifer is much easier.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sinoth&amp;gt; what changed to make it easier? don't see it on the dev_notes&lt;br /&gt;
&lt;br /&gt;
&amp;lt;VeryInky&amp;gt; Non dirt squares no longer automatically refill.  IN other words, it's now possible to make a wall and block the aquifer.  So you can build deeper; wasn't possible before.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sinoth&amp;gt; ah ok, thanks much :)&lt;br /&gt;
&lt;br /&gt;
&amp;lt;VeryInky&amp;gt; It's none the less MUCH easier with magma. Dig channels until you reach the aquifer, then divert magma into it. It turns into solid obsidian and you can just continue on.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sinoth&amp;gt; i wasn't aware you could build pumps solely with stone.  don't you need the [[enormous corkscrew|screw thing]], made out of metal or wood?&lt;br /&gt;
&lt;br /&gt;
&amp;lt;VeryInky&amp;gt; Requires a stone, but you can make the screw and pipes out of wood.&lt;br /&gt;
The problem is getting that stone.  A stone.&lt;br /&gt;

== Technical Nomenclature ==&lt;br /&gt;
&lt;br /&gt;
I'm tired of being unsure of what to call either end of the pump so that other people can understand what I am saying. I propose that we come up with a particular set of terms to define how the pumps are setup in any description or example.&lt;br /&gt;
&lt;br /&gt;
My proposal is as follows.&lt;br /&gt;
&lt;br /&gt;
* Name: Screw Pump Block or Pump Block&lt;br /&gt;
* Acronym: SPB or just PB.&lt;br /&gt;
* Description: This is the end of the screw pump which is dark when the screw pump is being built. It blocks creatures and water.&lt;br /&gt;
* Symbol: %&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
* Name: Screw Pump Step or Pump Step&lt;br /&gt;
* Acronym: SPS or just PS.&lt;br /&gt;
* Description: This is the end of the screw pump which is light when the screw pump is being built. It can be walked on, and this is where the dwarf will stand to run the pump.&lt;br /&gt;
* Symbol: $ &lt;br /&gt;
&lt;br /&gt;
This will make it easier to tell where the pump faces when only a diagram is given. Such as the following. You can easily tell that the PB is on the left, and thus the pump is pumping right to left.&lt;br /&gt;
&lt;br /&gt;

Raw adamantine is magma-safe.  I know we all ''knew'' that, but I've tested it.  In particular, I built mechanisms out of raw adamantine and tested them on a raw adamantine floodgate.  All the loose stone has since melted, but the gate continues to open and close just fine.  And while raw adamantine is rare and valuable, at least it's less rare than bauxite....

&lt;br /&gt;
My proposal is as follows.&lt;br /&gt;
&lt;br /&gt;
* Name: Screw Pump Block or Pump Block&lt;br /&gt;
* Acronym: SPB or just PB.&lt;br /&gt;
* Description: This is the end of the screw pump which is dark when the screw pump is being built. It blocks creatures and water.&lt;br /&gt;
* Symbol: %&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
* Name: Screw Pump Step or Pump Step&lt;br /&gt;
* Acronym: SPS or just PS.&lt;br /&gt;
* Description: This is the end of the screw pump which is light when the screw pump is being built. It can be walked on, and this is where the dwarf will stand to run the pump.&lt;br /&gt;
* Symbol: $ &lt;br /&gt;
&lt;br /&gt;
This will make it easier to tell where the pump faces when only a diagram is given. Such as the following. You can easily tell that the PB is on the left, and thus the pump is pumping right to left.&lt;br /&gt;
&lt;br /&gt;

&lt;div&gt;I made some mockups of east-to-west pumps using Unicode characters, but we should really get some full-fledged graphical examples. --[[User:JT|JT]] 07:47, 31 October 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
Is it essential that the rear of the pump be adjacent to an open square over liquid?  I need to do some tests of that, I had assumed from my testing it was sufficient to have the pump just over liquid (so for example, have the rear square on a ramp into a lake) [[User:Matryx|Matryx]] 13:50, 31 October 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
:The rear end doesnt need to be over an open space it can be pumped straight out onto the ground. Fixing that now.--[[User:Lucid|Lucid]] 20:43, 31 October 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
::Uh, I found that when building a screw pump on open ground, above a mined-out section filled with 7 waters ont he floor below, nothing pumped through until I dug an 'Open Space' next to the pump handle. --[[User:Sukasa|Sukasa]] 20:52, 31 October 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
Is it possible to pump magma with a screw pump made of steel? [[User:Diabl0658|Diabl0658]] 04:55, 3 November 2007 (EDT)&lt;br /&gt;
:I'm going to try this, except I'll use a Bauxite block because I can and there's lots of Bauxite on my map, I'll let you know how it turns out. (My last attempt at pumping magma ended with fire and death; Wood Pipe section, Stone block, I can't recall what kind of corkscrew.) --[[User:CrushU|CrushU]] 21:27, 7 January 2008 (EST) [[User:CrushU|CrushU]] 21:27, 7 January 2008 (EDT)&lt;br /&gt;

Has anyone confirmed the reynard diagram works? I was under the impression he meant it as conjecture [[User:VengefulDonut|VengefulDonut]] 14:10, 3 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
:just tested it. its fine [[User:VengefulDonut|VengefulDonut]] 14:19, 3 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
::In the reynard diagram tower are the fronts of the pump over the water on the square besides that?&lt;br /&gt;
&lt;br /&gt;
Maybe this is helpful?&lt;br /&gt;
&lt;br /&gt;
[[image:PumpWestExamplefix.png]]&lt;br /&gt;
&lt;br /&gt;
This is an example of a pump facing West in wonderful 3D.&lt;br /&gt;
&lt;br /&gt;
A: A square below the level of the pump without a floor where water is pumped from&lt;br /&gt;
&lt;br /&gt;
B: The point in which a dwarf operates the machine&lt;br /&gt;
&lt;br /&gt;
C: The three points in which water is deposited. [[User:MikeWulf|MikeWulf]]&lt;br /&gt;
:It's deposited only on the far C tile but leaks into the others from it [[User:VengefulDonut|VengefulDonut]] 09:27, 6 November 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
I can probably do a few of these for the digging article too if it is acceptable.&lt;br /&gt;
&lt;br /&gt;
:What program did you use to make that graphic? I wouldn't be able to make something like this unless I had a laser pen or somethin'. [[User:Schm0|Schm0]] 08:53, 5 November 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
::Just OpenCanvas with a graphic tablet. If the wiki wants uniform pictures I could probably do them.&lt;br /&gt;
&lt;br /&gt;
After seeing the new quote on the main page and seeing the bottom of this article, I'm totally opening up a dwarven gym with pumps and, if I can figure out how to make them use it, a swimming pool.  -[[User:EarthquakeDamage|EarthquakeDamage]] 20:46, 14 November 2007 (EST)&lt;br /&gt;
:Okay then, I'll put this bug in your head: If you build a pool with an adamantine floor, it'll look like lane markings :) [[User:Doctorlucky|Doctorlucky]] 03:45, 16 November 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
Just added a note that stacked pumps have to be built from the bottom up in order to fulfill their support requirements.  This may seem obvious to the initiated, but it frustrated me for quite some time. [[User:Doctorlucky|Doctorlucky]] 16:26, 16 November 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
I hear while draining ponds, screw pumps appear to create more water than they destroy, allowing some unexpected flooding. Does this mean, then, that you can take a single half-full square of water and eventually recycle it enough to fill a pond? Or is screw pump flooding just greatly exaggerated? --[[User:Knivesu|Knivesu]] 07:00, 3 December 2007 (EST)&lt;br /&gt;
:Actually got a chance to test it, appeared to create and destroy the same amount. Darn, and I was hoping for an automatic-refilling well. --[[User:Knivesu|Knivesu]] 22:38, 3 December 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
== Mud ==&lt;br /&gt;
&lt;br /&gt;
My screw pump seems to be producing a lot of mud and emptying it into the brook.  Is this going to do something bad to my water supply, or am I alright as long as I stay upstream of the mud? --[[User:Sk128234|Sk128234]] 13:08, 17 November 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
:I'm 99% certain that it's pretty much impossible at this point to contaminate a water supply. Heck, any pond shows as a &amp;quot;murky pool&amp;quot; and dwarves will use it freely, and making a pond by flooding a roomful of goblin invaders makes a perfectly usable pond despite the obvious issues of the rotting drowned goblins. So, there shouldn't be any problems either way. [[User:Kefkakrazy|Kefkakrazy]] 20:13, 19 November 2007 (EST)&lt;br /&gt;

&lt;div&gt;Should probably include some information on melting the ice, as this is a common question. [[User:Sinoth|sinoth]] 10:44, 16 November 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
Ice is listed as a fire-safe material, and fire-safe materials are listed as being usable for creation of magma-powered buildings. Does this mean one can make a magma forge out of ice stones? [[User:Rkyeun|Rkyeun]] 14:29, 24 November 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
I tryed to get water out of ice by dropping it a floor but it did not work. What am I doing wrong? [[User:Diabl0658|Diabl0658]] 23:49, 30 November 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
:It no longer seems to work as of 33d, I'm removing that part from the page [[User:Klada|Klada]] 20:55, 3 December 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
Regarding melting ice, I found that if you melt ice, drain it off to a 2 or 3, and then shunt the magma off somehow (happens often when magma first flows, due to ebb and flow of the magma waves) the 2-depth water will re-freeze, allowing you to re-thaw it into a 7-depth water. ... I found this out the hard way actually, since the magma waves caused successive re-thaws for the water to flood out my then-thought-to-be-way-too-big water pit. --[[User:CrushU|CrushU]] 21:20, 7 January 2008 (EST)[[User:CrushU|CrushU]] 21:20, 07 January 2008 (EST)&lt;br /&gt;
&lt;br /&gt;
==Value of ICE==&lt;br /&gt;
What's the material value of ice? 1? [[User:Noctis|Noctis]] 07:51, 31 December 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
:Whatever ice boulders are worth I would assume. Probably 2. [[User:Lightning4|Lightning4]] 08:31, 31 December 2007 (EST)&lt;br /&gt;
::0 Water is free so is ice. It doesn't even have a material entry it is hard coded in the game I think. --[[User:Ikkonoishi|Ikkonoishi]] 10:56, 31 December 2007 (EST)&lt;/div&gt;</summary>
