40d:Screw pump

A screw pump can lift water from below onto the same level as the pump. Its is two tiles by one tile in size, and can be either manually operated by a dwarf with the pump operator job or by using gear assemblies connected to water wheel or windmills. The direction you want the water to travel must be chosen at the time of construction.

Construction requires an enormous corkscrew, stone blocks, and a pipe section. Having specified the direction of travel, you must ensure that the source side of the pump is placed adjacent to and above (in the Z axis) a liquid. The screw pump will draw the liquid up from below, and distribute it out of the other side of the pump. Screw pumps are constructions that can be removed to recover the building materials.

Notes

• The source of the pump must be directionally adjacent to "Open Space" that is directly above a filled pool of liquid.
• The pump can be walked over by dwarves but the front of the pump must be accessible to be operated manually.
• Active mechanisms connected to the pump will automatically start the pump; to prevent this either restrict water flow using floodgates or put in a gear linked to a lever to disconnect motion.
• Pumps can also be used in conjuction with a waterwheel to become self-powered.
