Is there any way to make water go up? as in if i have a channel from a river to my fort but there is an upward hill in the way can i make it go up the hill?

[FrankyPlaysGames]

Seven words:
Screw pumps.

[Domicrow]

One of us is bad at maths... and i just started DF so i dont know what that is but i will check the wik, thanks =)

[Domicrow]

So how would i be able to do this?

im planning on kinding of diverting the river through my fortress as a convenient water source

[EvilBob22]

Put it (pumping from the North) on the first two up ramps.  The tile one north and one down is where the pump pumps from.  Also, the more northern of the two pump tiles can be stood upon without worry.

This is fine:

Code: [Select]

,,,_,,,
,,,%,,,
,,#%#,,
,,#~#,,
,,#~#,,

, = grass
# = wall
_ = pit
% = pump
~ = water


[Domicrow]

ummmmm... fuck that just went straight through me =(  oh if only i had an IQ higher than my shoe size

[Boltgun]

A better explanation here :
http://dwarffortresswiki.org/index.php/Screw_pump

Basically you remove the first 2 tiles of upward ramp and build a pump there. It will bring the water up. It is not as complicated as the wiki page make it look, the only hard part is to set the right direction before validating your construction.

Ah thanks Bolty McBoltchap, that kinda makes sense, i'll let yuo know if that works =)

[Domicrow]

Hurray! it worked... damn now i need someone to explain water wheels to me

[Lich180]

Waterwheels are built over a water source that has "flow". This means either a brook that has been channeled into to remove the invisible floor over it, a river either natural or artificial (if artificial, it needs to flow off the map edge, through a carved fortification) or an aquifer that has been channeled into and flow induced to it.

A river is probably the easiest way to get them working, then you have to use gear assemblies constructed from mechanisms, and horizontal/vertical axles made from wood logs to transfer the power they produce. The axles have to be set to a direction (E/W or N/S), then can be made up to 10 tiles in length, using at most 3 wood logs per axle.

[I know its already answered, but....]

Just how much pressure do you want the water to come out with?

If you just want it to ooze up out of some floor grates, standard overunity screwpump systems work great.

If you want to fire whatever is standing on the tile skyward with enough force to cause lethal trauma, you will need a pressurizing tower.

Others have already discussed screwpumps.

A pressurizing tower works like this:

Code: [Select]


|........................|                          [sky]
| water in here |
|                               |
|                               |
|                               |
|                               |    [ground]---V        [floor grate]--V
|                               |
|                               |------------------------------#-----
________________X <--[floodgate]__________________|


Water builds pressure with each Z level above the layer the water gets released on, that the water tank is above that level.  Eg, the example has 7z above the surface for the top level of the water. The water will be able to flow uphill that many z levels, so the water shooting out of the floor grate when you open the floodgate will be quite forceful, and profound.

Another thing to note is the amount of water that will flow.  Tank pressurized water will flow at 7/7 units via "teleportation", so all the water above the ground level will VERY rapidly gush up and out of the grate almost instantly, until the level in the tank is the same as the ground level. If you have a very large and very tall tower, that will be a LOT of water.

(Note, magma does not pressurize this way.)

To get water into the pressurizing tower, just use a standard pumpstack to deliver it.

For maximum fire speed, put the floodgate as near to the floorgrate as possible, so the pipe stays fully pressurized.

Aiming the outlet to be horizontal instead of a vertical gyser port is a GREAT way to blast intruders into a spike trap.

Hurray! it worked... damn now i need someone to explain water wheels to me

Water flowing under the wheel causes the wheel to generate power.  Use axles (made of logs) to transfer the power from the wheel to other mechanisms (such as your pump).

If you are diverting the river, I suggest (recommend is too strong a word) the following style setup:

lower level    upper level
++XXXXXXXXX      +++++++++
_%%~~~~~~~~         WWW       %% screw pump    WWW water wheel
_%%~~~~~~~~      *---*        * gear    - axle    + floor    X wall
_%%~~~~~~~~                   ~ water    _ channel (lower level water)
++XXXXXXXXX      +++++++++

I can't remember off hand if the wheel is 3 or 5 tiles wide, but the axle connects to the center of it. The gears turn the connection toward the pump (right gear turns toward the pumps, left one turns it down) and provide power.  A lever attached to one of the gears will allow you to disengage it so it stops transferring power to the pump(s) in case you ever need to work in the waterway itself.

I haven't actually built this, but it should work.  At worst you need to run the axle out to the side first.

Cor blimey i've barely learned the basics yet i think i will just make 3 exclusive manual pumpers for now but thanks guys i will look back at this thread if i ever decide to go beyond the basics of this rediculously complex (to idiots like me) game =)

So how would i be able to do this?

The alternative to building the screw pump would be to channel out those up-ramp tiles so that your new channel for the water is at the same level as the river.  Then you don't need any pumps and you don't need to worry about powering the pump or dealing with the pressurized water.

Normally when I want to bring water inside my fort, instead of using channels, I simply dig a horizontal tunnel from the fort to the edge of the river -- on the first z-level below the surface (i.e. into the side of the river).  Leave the very last tile in place, so the tunnel is still dry.  Install floodgates, drawbridges, traps or whatever other defenses/controls you want in the pipe.  Then channel out the very last tile from above, and the water will start to flow in.

By contrast, what you've done here with the open channels is create lots of places where flying or swimming enemies can get into your fortress.  My method only exposes one tile (which could be floored over) and the river itself (which also could be floored over, if you really wanted to), and gives you the opportunity to build defenses in the pipe itself.

Heh.  Give it a try. Getting a water wheel to power the pumps is actually pretty easy.  The design I posted above needs the wheel, two gear assemblies and either two or three logs (from memory). It can power at least two pumps, if not all three.
