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.

Building a screw pump requires an [[enormous corkscrew]], a [[block]], and a [[pipe]] section. The construction itself is completed in two stages. First a dwarf with the [[architect]] labor must design it. Then a dwarf (the same or a different one) with the appropriate labor must complete the building. This could be [[carpentry]], [[metalsmithing]], or [[masonry]], depending on the material of the block. | Building a screw pump requires an [[enormous corkscrew]], a [[block]], and a [[pipe]] section.

* 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).

If the pumps are "open" (that is, built on channeled tiles) to each other across z-levels, then a stack only requires (sufficient) power to be tranferred to one pump. All others will be powered by association with the first. You can transmit power to each pump by simply channeling out the floor at the front (aka output side). |
