Using Water & Water Pressure 🔅DWARF FORTRESS STEAM🔅

Dwarf Fortress features some pretty complex behavior in an attempt to simulate fluid mechanics.
One aspect of this behavior is seen in the form of pressure. The basic idea here is quite simple - certain forms of fluids movement exert pressure, causing them to potentially move upwards into other areas. Knowing how to manipulate pressure as needed allows you to quickly move fluids wherever you wish in your fortress allowing you to build things a dwarf can be proud of. Note that fortifications do not neutralize pressure.
There are three methods for neutralizing fluid pressure: diagonal connections, screw pumps, and active control systems.
Diagonal Flow: Liquids moving via pressure can only move to orthogonally adjacent tiles. When faced with a diagonal gap, pressure will fail to move the liquid, forcing the liquid to instead spread out. By forcing fluids through a diagonal connection you can prevent pressure from propagating past a certain point.
This does not work on a vertical basis - water only travels straight up and down to different Z-levels, never diagonally.
Water in a U-Bend
The key to understanding how high a z-level water will reach is to understand which tile(s) pressure is being exerted on. Pressure will cause the water level to go as high as the tile upon which pressure is being exerted, but no higher.
Water can be displayed in two ways, depending on the settings in d_init.txt. By default it is displayed with the symbols ≈ and ~, sometimes colored different blues, and white, showing ripples, and flow. Setting [SHOW_FLOW_AMOUNTS:YES] in d_init.txt will cause water to display using a depth indicator of 1 through 7 instead. Water can also take on other colors indicating contaminants such as blood, ichor, or goo.

Ancient Bridge Magic:
An old way to safely breach water or magma. =)
Miners are able to mine out tiles diagonally above them even if there is a bridge over their heads. First you dig out your magma/water tunnel to feed wherever in your fort you need it and dig it right up against the warm/damp stone. Then you channel against the warm/damp stone. Build a magma-safe bridge over the trench, making sure to cover all channels, and then seal off access. Dig a new separate path to access the now bridged-over trench. Finally, designate the warm/damp stone wall on the Z level of the tunnel for mining. Your dwarves will stand on the ramps beneath the bridge but will somehow still mine out the squares diagonally above them, causing the Fluid to flow safely onto the bridge leaving your dwarves unscathed."

[@bdeink]

If you're relying on off-map drainage using fortification edge tiles for your water features, e.g. waterfalls, be very careful with visiting your fort in adventure mode later! In adventure mode, the map edges are not necessarily the same, and you'll end up flooding the entire thing! Allegedly. This has obviously never happened to me... 😳

[@TwistedLogicGaming]

Good tip! Thank you for you wisdom bdeink!

[@Warwipf]

This is fixed in the Steam version by just not having Adventure Mode included :^)

[@MrGrumblier]

Sounds like more FUN.

[@meneither3834]

I suppose you got to drain the water in the caverns or the magma sea then.

[@head0fmob]

@@meneither3834or just direct it back to original source? like 1 floor below the sea/ river it originated from

[@FolixOrision]

I flooded my base again, this pressure guide explains why it happened. Got a pump set up to pump it out, but from this, i can pump it off the map. Thank you for the tips.

[@TwistedLogicGaming]

you can also use gravity to drain the water without pumping if you can dig a big drain! Happy Gaming

[@FolixOrision]

@@TwistedLogicGaming That is actually what saved me. I was prepping an area on the bottom level that I had yet do do anything with. Water flowing down into bottom floor was enough to get some 1/7 levels in for flood gates till I fixed the water issue. My ideas was to divert the stream, then use the rock slits to filter all the fish into one spot, then fish that area. Turns out the fish went though the wall slots and I needed to add in grates. It was at that time, enough pressure had finally up that water came up my wells, leading to surprise flooding. I knew from years ago that a dead body in the water can make it go bad, so I am trying to create running water that will carry anything bad out, possibly creating a catch to filter out anything that fell in. Wasn't aware that pumps purify the water. Also wasn't aware that creatures could be pumped. I look forward to try out some of the water traps in the future. Thank you for making these videos.

honestly i'd recommend just throwing yourself into Dorf Fort with a basic tutorial (wiki quickstart guide is good) and accepting that things are going to go terribly wrong at some point. Read/watch more once there are specific mechnics you want to understand. Losing is fun.

[@andrewevenson2657]

I am new to dwarf fortress, got into it because of the steam release, and I am blown away at how in depth these mechanics are. The fact that water has pressure and can move objects, it seems very simple, but it’s honestly incredible to me. I’m still brand new so there is a lot to learn yet, but I like it so far.

df steam has really kicked off a fortress engineering education renaissance. i've read the wiki's water articles so many times and followed countless forum threads, but this video really makes all the water tricks really stick in my mind for once. i think it's the combo of watching you build it and having a clear tileset

[@TwistedLogicGaming]

Thank you for watching!!

Last night I made a naive water tunnel from a brook to my base accessed via a well, and needless to say, it flooded my base! Thank you for this guide! I also like the sound of your laugh, it's so sinister lol

[@TwistedLogicGaming]

Hahahahaha, I don't know why I sound so sinister, I get that alot. I'm happy this was helpful ! Happy Gaming!

[@quintosh]

You can build a bridge to your water tunnel and connect it with a lever, open up the river, and when you have enough water just pull the lever and the bridge blocks the water from flowing any further :) You can use the same thing to block entrances to your base too

[@crocfighter.1322]

Years ago I made a fort in an evil biome during class. I may have forgotten whatever shakespeare quote we were analyzing that day, but I will never forget the pressurized water bursting out of my well and flooding the entire fortress while the zombies--remains of a migrant wave to top it off--watched and waited for the delicious dwarfs to come out. A few weeks later I decided to wait until the steam release to play the game again, and now I can do it confident in my ability to not drown! Thank you for the video.

[@TwistedLogicGaming]

HAHAHAHA Love the short Story

[@roguelove807]

THANK YOU! I was so confused by water mechanics! Explaining the way to build U-bends and the diagonal pressure reset mechanics was REALLY helpful. I especially liked the side-view picture you made to show the u-bends and how they worked.

[@TwistedLogicGaming]

Glad This helped Roguelove ! Happy Gaming

[@shyPandemonium]

This was my favorite part as well ☺️

[@robertmiller7921]

One tip for the edge drainage: use channeling to make it two tiles deep, with two levels of fortifications. Because of the way flow and pressure work, it will drain much more quickly and efficiently. (If your fort is flooding you definitely want the drains operating efficiently.) You actually only need a single tile wide drain this way because of how fast the water will flow out.

[@TwistedLogicGaming]

100% correct

Great guide, as a total DF newbie I was wondering how I could move water around after I found out I was supposed to prepare a water source BEFORE winter strikes as the outside water source freezes over! This video perfectly explains multiple methods that I can more or less understand and definitely do with a bit of effort on my end. I'll likely be doing the old timey strategy just to be quick about it but i'll be coming back to this guide to do it the fancier way when I've got a water source set up at least

Man, just wanted to show my appreciation again. You, Nook and Dastastic are my go to when learning dwarf fortress. I've been playing this game for around 3-4 years and it's still crazy the amount I learn from each of your videos. Thanks so much for your work man! The way you calmly explain everything slowly but at the same time without treating as if we didn't know basic stuff is so good. There are many tutorial makers but they are usually: A. Too fast or B. Assume nobody knows anything and just go tooo slow over the explanation. You have a thing for hitting the right spot. Gonna check your playlist but just to leave the idea here if you don't yet have one think about having a tutorial fort series. I would love to watch that! Thanks again mate!

[@219nate]

Awesome video as always!, something to add that might be useful that you did but didn't mention, is that it can be helpful to make the cisterns under a well to be 2 tiles deep. That way any contaminants brought in or even mud formed during the initial flooding won't cause water brought up from the well to be dirty which can cause other issues.

I could be wrong but I think it would be better to designate the mined tiles as red traffic zones so they won't stand on them. Otherwise there can be a situation where one dwarf stands on one of the tiles to mine another one while the other dwarf mines the tile beneath him. I remember reading something like that on the wiki.

[@TwistedLogicGaming]

Yeah that is correct however I was watching them, and if a dwarf was standing on a tile desegnate to channel you or I could also erase the designations on those 2 tiles before the job is complete and then you will not need to set and remove a traffic order. For larger jobs I would do how you discribed. Thank you very much for bringing that to light trafic areas can be super helpful !!

great guide, keep doing these for all the technical elements please! one question though. If I want to get the water pressure equalised to a specific layer (e.g. 20 layers below the water source) do I need to do lots of step downs or just do a diagonal branch off at the specified level - thus creating the new water level?

One thing I've been thinking of doing is creating a fort where dwarves need to swim to navigate the main floor, in an effort to train swimming in everyone. Like, just carefully control the water flow and have every room with a triple-airlock with drainage between doors, and keep the hallway flooded with exactly 4/7 water. Obviously it would reduce efficiency by a lot, but I figure if I make the bedrooms, temples, and tavern on a separate floor from industry+barracks+hospital, it wouldn't really impact the speed of their work too much. It'll probably be hard to do but imagine having a fort where all your dwarves are at least competent swimmers and you can have all the moats you want without worrying about everyone drowning.

[@TwistedLogicGaming]

[@leandroschenone7253]

Another great great video! I'm very happy knowing that after too many years always can learn something new.. can we use this system to create a "inside" fish source? I mean.. with the grates, fortification or bars.. The fishes can go through?. HESSED

[@TwistedLogicGaming]

The fish will not go through grates, However you can fish through the grate,(unless this was changed) so a we will need to be build ontop of an area where you have access to water that is outside the fortress. Like an over hang; Think Ice fishing!! Thank you for watching Leandro !! Happy Gaming!

[@__xxx_xxx__]

I've tried that trick and it worked, by and large. The only trouble was, it would kill a poor sod once in a while (maybe 2 per year). That would happen when another little critter fell on top of a swimmer, due to the well known and ancient bug that turns any falling object into a deadly projectile. As for lining up the floor with a low density material, it does indeed soften the impact, but even with raw stone (shale in my case) the fall in itself was not dangerous. I went for a water ride instead : a 20x2 circular minecart track that dives through a 4-deep water pool and gets propelled by four "impulse ramps", with just enough friction for the cart to climb back up and come to a halt after a full loop, ready for another ride. No pressure plates or anything, just a route with a single stop ordering a dwarf to take the ride :) However, now that the steam release has removed the option for the doors to keep the pets out, a kitten or a puppy might wander into the room and get squashed once in a while. Well, that's already an improvement, innit?

[@spartangamers7783]

Just wondering why you can only create a new pressure level above the level of the grate as referenced at 7:45 ? Does water have to go up a number of z-levels in the u-pipe to be able to be diagonally pressurized?

[@TwistedLogicGaming]

NO, that is to maintain the safty of the fortress. from cleaning the water and creatures sneaking in

[@TwistedLogicGaming]

You can use the diagonal anywhere ! that splits the water off into a new "body of water" and resets pressure to that z level . I was trying to do that in a specific application but its a sandbox game so when teaching it is best to set a few limits

[@TwistedLogicGaming]

Thank you for watching SpartanGamers !

[@evilcreature_0435]

Does the desalination trick still work? I've set up a U pipe connected to the ocean and did like you did in the tutorial, but the water appearing in the edges/corners is still salt water.

[@TwistedLogicGaming]

it's not a trick.. It was an observation. the water should not have been desalinated! Water may currently be desalinated by passing it through a screw pump.

[@TwistedLogicGaming]

Found this: Alternate water purification methods Contamination in the form of salty or stagnant water is apparently unable to climb stairs. Lacking the materials to build a screw pump, you can instead purify water by forcing it to pass through a vertical u-bend made of stairs. Flowing fresh water destroys stagnant water on contact, converting it into fresh water. Oddly enough, flowing salt water also destroys stagnant water on contact, converting it to fresh water, so connecting your murky pools to the sea paradoxically provides clean drinking water.

I'm gonna try going around it and, if I fail to get there in time again, I'm probably going to let her -get killed- have fun.

[@TwistedLogicGaming]

you can also smooth stone the walls of an aquifer to stop them from leaking water if they are stone walls ! or perhaps if a trade caravan somes in time !! Good Luck Ian !!

[@mauriciobirgi5083]

So... I need to go level by level with several U pipes or can I do just a very deep one?

[@TwistedLogicGaming]

I just did the one u pipe; consider that the "water main" everything after that should be safe. then use the simple diagonal to reset pressure where ever after that inside the fortress !

[@ohiocoder8313]

does magma pressure not work the same way? I have a U shape pipe but it's not going up on the right ride of the pipe

[@TwistedLogicGaming]

no magma will olny be under pressure when using a screw pump ! otherwise there is no pressure on magma and only uses flow

[@joshualajoie9547]

If the floor grate bypass is only blocked off by doors, couldn't building destroyers break the doors and get up to the z level of the grate unless the bypass stairs are also removed and grated on the same z level?

[@TwistedLogicGaming]

building destroyers need to be on the same z level to destroy the grates, this protects from the bottom only. The Floors on top prevent them from coming down from above, Thats when i "button it up" the up stair should be on the same level as the grates in the fliter ! I hope that helps! Thanks Joshua!

[@McSleepygaming]

I've been playing for nearly a decade and I never new a u-bend could desalinate water. Is this a new feature?

[@TwistedLogicGaming]

This seems to be new feature or a bug, Thank you for asking please keep it a secret ahahahah

[@McSleepygaming]

@Twisted Logic Gaming Well, while it lasts, which could be a long time I will enjoy the cheaper solution.

[@ulflonegren4870]

My current fortress is deep in the caverns on a frozen barren island, so no water up above. I’d like to take advantage of the cavern lake. Can you explain your last magic trick? What can you do after you open access to the lake like that?

[@TwistedLogicGaming]

This is a way to breach a cave lake, ocean, magma sea, ect. with out having to bring your dwarves into the caverns or an imposible location like standing in magma. after the breach is complete you can dig a reservoir or tubes to bring the liquid where ever you need. once the area is safe and complete pull the lever to flood the area. you can then close this later if you want; if you were to leave it open all the time I would build a U pipe after the breach to prevent forgotten beasts from entering the water tubes.

[@TwistedLogicGaming]

The bridge will block the flow of magma or water & the dwarfs pathing. Mining is not blocked by the bridge and the dwarfs can stand on the ramps to access the level above. when a dwarf is on a up ramp they can access the level above them.

[@ulflonegren4870]

@@TwistedLogicGaming Gotcha, that's awesome. A short video demonstrating this use case in more detail would be cool. But thanks, this makes a lot of sense!

what was the use of the last one? is it to make the higher floor have water access but bottom one don't? I feel like if the dwarves can mine the tile above, then water should be able to go down, no?

@@TwistedLogicGaming oooooh amazing! Yes it is indeed an ancient magic!

[@Luganoo]

I have a problem with U-Bends like the one you did. For some reason, whenever I open access to it, water doesn't propagate at all, just some 1/7 tiles and that's it. Why does that happens? It's basically impossible to do something like the reservoir done at 10:43

[@TwistedLogicGaming]

I think this has to do with a water pressure bug if I am correct. please see this video about it (sorry for the quality this is an older video) kzbin.info/www/bejne/ooaYe5h_nLKppaM

[@TwistedLogicGaming]

let me know if that bug seems like the one you have . Thank you for watching !

[@Luganoo]

Not completely sure if it's the same since I can't 100% follow everything going on, but it seems to be similar. I will try to describe as best as I can. From a side view, "w" is water, "g" is where I have stone grates, "d" is where I have a door connected to a lever that blocks the flow, "|||" is where I want the water to flow at level 3. This is how my configuration ends up being when I connect with the river at level 6. 6 www 5 w w 4 w w 3 w w w d ||| 2 w w 1 w g 0 wwwwww Now let's say I open the door at level 3, this is what ends up happening. 6 www 5 w 4 w 3 w w w d w w w w w ||| 2 w w 1 w g 0 wwwwww The water propagates for a moment and that's pretty much it, at the u-bend water never really goes above 1/7 (it's a 2x2 u-bend), and the water that propagated ends up drying, resulting in this. 6 www 5 w 4 w 3 w w w d ||| 2 w w 1 w g 0 wwwwww If I close the door at level 3, the water never goes up again, with level 4 and 5 remaining empty forever. Now, I have tried connecting the water at level 3 to the hall I want it to propagate in both ways, diagonally (so it becames it own body of water) and non diagonally. With both cases I have the same results. I have tried flooding the u-bend first, then connecting to level 3, same results. I have made a 1x1 connection to level 3 first, blocked by the door, and then flooding the u-bend, same results. It may be worth mentioning, but the lenght of the tunnel at level 0 that connects to both parts of the u-bend is longer than what I depicted, but that doesn't seem to be a problem since initially it always fill up to level 5. It's driving me absolutely insane and I am completely clueless on what is going on. Edit: After going through all this and watching the vid you mentioned again, it seems to be the same bug, because at level 3 the flood doesn't "complete" and the pressure check seems to die, never going above 1/7 again. Can be replied at any lower level with the same results too. Fuck me.

[@TwistedLogicGaming]

seems like the door is causing the flood fill to fail, & causing the pressure bug in that video there for flagging eveything after that door as static. I might have to create a new version of that video for the steam version; but that seems to be the issue... To test this: save a back up file. then dig over to the water on level 3 without breaching any damp tiles and see if water flows. basicly forcing a block update in the area of the water. W dampstone (do not breach for test) S stair M Mining tunnel D door Top down level 3: M M WWWWWW WSWWDWW WWWWWW Let me know Lugano V !

[@Luganoo]

@@TwistedLogicGaming Sorry I forgot to mention that I tested without using the door (both having it placed and not placed while the water enters through somewhere else) and got the same results, water propagates to 9 tiles away at most and at the stairs water remains at 1/7. I'm pretty confident that the door, no matter how suspicious it looks, is not at fault here. I tried something different and... it kinda works but now I'm beyond confused. I will describe it using the real size. - Basically the water enters from the river to a tunnel, it moves 10 tiles to the East. The last 2 tiles are a 2x2 stairs. - Water goes to the Bottom of the u-bend through the 2x2 stairs. The u-bend is 11 tiles deeps (which means water should go 10 tiles up at the other side). - At the Bottom of the u-bend, the water moves to the East for 90 tiles, the last to tiles are a 2x2 stairs. - The water goes up 10 tiles, completing the u-bend flow. At the top of that end of the u-bend, I wanna open a section to the South that is 16 tiles long for a well. When I try that (with or without a door), basically all that I described before happens. Water floods at most 9 tiles to the south before the stairs get permanently stuck at 1/7 depth. BUT what I did now, rather than opening to the South, is opening to the West. Did a 18 tiles long tunnel (2 tiles longer from what I wanted the water to propagate to the South). At the end of that tunnel (western most part), I did a small new u-bend that is 3 tiles deep. The tunnel is opened to the u-bend right from the start. Then I channel at the river, water starts to flow in and... it works. When the water goes 10 tiles up to the top of the u-bend, it then propagates with no problems to the West and it completely fills the new u-bend. My honest reaction was "what in the actual fuck is going on". So I tried again, but this time, rather than having the tunnel to the West at the top of the u-bend being open from the start, it was closed, and I went one level above and breached through channeling, just like you do in this video at 9:51. It DIDN'T work, water got like 10 tiles to the West, with the stairs being stuck at 1/7, resulting in the same problem that brought me here. So I went back to the original idea, which was the tunnel to the South that was blocked by the door. But this time, the door was open before I tapped the river. So I channel at the river, water starts to flow through the u-bend and... IT COMPLETELLY FILLS THE TUNNEL, going through the open door with no problems. So now I can 100% say the problem is that the pressure at the u-bend dies once the system is opened in any way AFTER it fills up. If I open the door so the water can flow, or I dig a channel from above, water pressure at the respective level of the u-bend ends up being oblitariated, no matter how. BUT, if the tunnel or the door are opened right from the start, then when the u-bend is filling up, it will propagate through that tunnel without problems. From watching your video and reading the wiki, I think it's pretty safe to call this a terrible bug :(

[@hushedturtle]

does the water pressure reset whenever i make a diagonal no matter what z-level i am from the water source? My water source is in elevation 40 and im trying to bring water to elevation -12

[@TwistedLogicGaming]

Yes! the diagonal splits the water into a new body of water, and there for resets the source tile to that level

[@ObsidianWlf-ck7ni]

.:) hey so @9:24 it’s not pressure cause you channel instead of mining diagonally? Or cause lvl was at -2 so it became equal and has to be pressured again. Great explanation tho just tryin to not drown the poor dwarfs

[@TwistedLogicGaming]

The pressure was not reset at that time becasues the gap was too big even though the water was moving in a diagonal direction. the small diagonal gap to reset the pressure is a box of 4 tiles; 2 are walls and 2 are open for water. ##~# #~##

[@ObsidianWlf-ck7ni]

You sir are an exceptional dwarf thank you

[@Mel-mu8ox]

can you make a trap with stones and water? so the water pushes the stones onto the creatures bellow crushing them, and floods any it misses? do stones float??? or is it stone type dependent?

[@juliocastro8788]

Hi Twisted Logic! What happens if I breach the ocean in its low levels? Does it pressurize to the surface of the ocean? Thank you!

[@TwistedLogicGaming]

Yes. the top of the ocean at the map edge are the source tiles of the water. the game will try to flood fill everything it can based on the body of waters source tiles. when making diagonals this splits the water into a new body of water with a new source tile. the new source tile is not generating water like the map edge tiles however we call both of them source tiles.

[@TwistedLogicGaming]

you must lock the door not forbid

[@MartialistKS]

I made this on my map exactly as you described only I was accessing a brook rather than the ocean. It did not work for me when I dug out the final channel from above as you did at 9:50 It only dribbles out for 11 tiles or so with a depth of 1 unit no matter how long I wait. I'm not sure if I did something wrong, if brooks behave differently than the ocean, or if this method has been patched somehow (unlikely). Your trick of the corner access "resetting" the water pressure to that level also didn't work for me, same dribbling flow as described above.

[@TwistedLogicGaming]

is the body water in a small area of the map (16x16 tiles) ? it might have to do with this rare bug: when a water flood fill fails the game code stops pressure checks in that area until there is a block update. Sorry for the quality of this older video in advance: kzbin.info/www/bejne/ooaYe5h_nLKppaM

[@MartialistKS]

@@TwistedLogicGaming I figured it out. User error, as expected. After I ate I was able to figure it out. I wasn't 100% clear on how the pressurization works if you divert the water coming back up the U-pipe before it reaches its maximum height or precisely how the corner leak method "resets" the pressure. With a few adjustments I was able to get it to work like I needed it to. Thanks!

Few questions with this if anyone can help: -How do you know the pressure of each Z level in the u pipe? -How or why does the U-pipe turn salt water into fresh water? -At 09:35, why does pressure not reset? I thought diagonal resets the pressure but here you say it will not reset? -What was the purpose of creating the drain construction at around 16:40?

[@TwistedLogicGaming]

-How or why does the U-pipe turn salt water into fresh water? - possibly a bug ? in the past we used the pumps to desalinate the water

[@TwistedLogicGaming]

How do you know the pressure of each Z level in the u pipe? the pressure of the U pipe is -1z from the souce tiles of that body of water

[@TwistedLogicGaming]

-What was the purpose of creating the drain construction at around ? to show you what is possible

[@TwistedLogicGaming]

At time, why does pressure not reset? I thought diagonal resets the pressure but here you say it will not reset? that is not considerd a diagonal in the walls and will not reset pressure because it is too wide. there for that area is still treated as the same body of water as the U pipe & ocean

[@TwistedLogicGaming]

Please see time 08:00 for an example of the diagonal squeeze/ this tight diagonal space splits the water into 2 separate body's of water. there for resetting water pressure for the new split body of water at that z level. that diagonal split becomes the source tile for the new body of water setting pressure to the split for that side only.
