People have created and used water wheels since Roman times. They have employed water wheels to pull water from mines, to grind grain and to run billows for Chinese iron makers. Three main types of water wheels have been developed; two vertical wheel models and one horizontal. Most model water wheels feature the vertical wheel design.
