A '''screw pump''' is a small [[building]] that can lift liquids ([[water]] or [[magma]]) from one level below onto the same [[Z-level]] as the pump. It is two tiles by one tile in size, and it can be either manually operated by a [[dwarf]] with the [[pump operator]] job or by using [[gear assembly|gear assemblies]] connected to [[water wheel]]s and/or [[windmill]]s. | A '''screw pump''' is a small [[building]] that can lift liquids ([[water]] or [[magma]]) from one level below onto the same [[Z-level]] as the pump.

* In order to build pumps in a "hanging" state, as in the stacked screw pump example (below), one of its tiles must be able to connect to a nearby machine, either already existing or designated to be built. If, when the screw pump's construction is completed, the supporting mechanism has not yet been completed, it will promptly collapse into its component parts. | * In order to build pumps in a "hanging" state, as in the stacked screw pump example (below), one of its tiles must be able to connect to a nearby machine, either already existing or designated to be built.

* Pumps do '''not''' push liquids '''up''' additional Z-levels above them. They only deliver water to their own level. That is, if you direct the output of a screw pump into a 1-square space surrounded by walls, the water will not "overflow" the walls. Consequently, a pump will refuse to move liquid if the level it is pumping to is completely filled. Higher levels can be achieved using a "pump stack" (below).

* Magma, which normally has no pressure, will behave like pressurized when pumped. For example, when pumped into an U-turn, magma will come out at the other end. Normal (non-pumped) magma would just pool at the lowest level. This may be either very useful (can be used to build pressure towers for magma) or deadly (forge level flooded with magma, because someone tried to pump magma into a volcano). | * Magma, which normally has no pressure, will behave like pressurized when pumped.

* Pump's pseudo-pressure doesn't work across diagonals.

− | + | I recommend that you connect a lever to one of your gears beforehand. The pump will start pumping as soon as it has power. | |

This is very useful for providing a source of potable water in otherwise entirely salt-water regions. However, if desalinated water comes into contact with natural walls or natural floors, other saltwater, or passes through a saltwater [[aquifier]] level (even if that has been sealed by [[smoothing]]), the water will be ''re''salinated. So any freshwater cistern (tanks) must be entirely constructed to the full level of the water, with no natural floors or walls that will come in contact with the de-salinated water. |
