A water wheel is a machine component that provides power via water flow. To build a water wheel, select build menu and choose Machine components. It requires 3 wood and generates 100 power, which can be used for operating a pump or mill. You can use axles and gears to access the power produced by a water wheel, or connect machinery like a pump or millstone directly.

Waterwheels have quality levels for both design and building. These can be checked from the room screen by moving to the entry and pressing enter.

Construction

The architecture and carpentry labor are needed for the construction.

A water wheel occupies 3 adjacent tiles (N-S or E-W axis, no diagonals).

Although you can build a stable water wheel on solid ground, this isn't going to do you any good. For this reason, water wheels are almost exclusively built in a hanging state with gaps in the floor below. To do this the water wheel must be attached to a nearby machine component. A water wheel can attach to other machines only on either side of its center tile.

Power will be sometimes generated once one channel tile under the water wheel is filled with water at a depth of four or greater if there also is a water flow in one of the three tiles beneath it (we need more info in the article on what constitutes waterflow). The easiest way to achieve this is to place the water wheel in a river, but also a brook or channel works if done right (read below). Having two floor tiles and one channel tile below the wheel is not necessarily working even if that one tile fulfilles the above conditions, but it can.

You can transport the power wherever it is needed via horizontal and vertical axles and gear assemblies. It is possible to support a waterwheel by building its center next to a preexisting waterwheel's center.

Brook

Intuitively one would place a water wheel in a river, but they can also be powered if placed over brook tiles, but only if you first dig through the surface of the brook. Build a channel three tiles long, right on the brook. The water wheel will sit above this channel.

Channels

It is possible to power a water wheel in a dead end channel if it is connected to a river or brook <read as: water that has flow. Further details needed.> A channel connected to a murky pool will not suffice, no matter what water movement is present in the channel.

Any direct non-diagonal connection (see water pressure) to a river or brook that has flow (some do not) will power a waterwheel, even if it's a dead end. In fact there is a quirky bug where a floodgate will not block this flow. The floodgate works, the water doesn't actually move, but the waterwheel still thinks it is directly connected to a flowing river or brook so it happily keeps churning away.

This is by no means the limit of water power from one location, depending on the width of your river/brook/channel you can stack many waterwheels side-by-side (really big assembles will need to be artificial as there's a limit to how wide the game created water flows get). Just remember to make sure there's a support structure in place before you place the next wheel.

Perpetual motion

Due to the low power draw of a screw pump, a self-powering assembly can be made with a water wheel that still leaves plenty of excess power for other uses. This is an exploit, and possibly a bug.

A simple design is available at this forum post.

A third with only 1 channel, under the middle tile, works. I suspect tiles right next to the water wheel play into it too, or the design of the channel leading to it from the river-->
