[edit] 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

≈	≈	≈	o	═	═	═	═	═
≈	.	.	.	.	.	.	.	.

5. Finally, throw the lever, add your screw pump and the final wall section

≈	.	.	.	.	.	.	.	.

[edit] Alternatives

• Skip the lever and gear and power the pump directly, "always on".
• The "Blowback" wall method:

≈	.	.	.	ó	.	▲	.	.
≈	≈	≈	o	═	═	═	═	═
≈	≈	≈	%	%	*	.	.	.
≈	≈	≈	o	.	╔	═	═	═
≈	.	.	╚	═	╝	.	.	.

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.

[edit] 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.
