Draining a pond
1. A Pond To Drain
2. Add Some walls to control output, and an access ramp (leaving access is a good idea)
3. add 3 floor tiles above the gap, then build your windmill
4. build a lever and gear assembly, then link your lever to the gear
5. Finally, throw the lever, add your screw pump and the final wall section
Alternatives
- Skip the lever and gear and power the pump directly, "always on".
- The "Blowback" wall method:
This allows water to flow past the pump when the pump is off, meaning that one pipe with a pump at each end can send water either direction, based on which pump is on. It also allows for maintenance access from the pipe, at the cost of 3 extra wall sections and one extra floor.
A simple pump with lever
Side view:
=O= <- windmill supported by unlinked gear assembly
** <- two gear assemblies: left gear is linked to lever
@@ <- screw pump
~=~=~##### <- water
##########
The right gear does not need to lie on the screw pump, as long as it's orthogonal to the gear that -is- placed over the pump.
