Waterwheel

CategoryStructures & Machinery

Historical usage

A wheel turned by flowing or falling water, used for pumping and ore crushing wherever a mine could bring water to it — usually via a leat (see that term) if no natural stream ran close enough.

How it worked

Water directed onto or under the wheel turned it, and the wheel's rotating shaft was then connected to whatever machinery needed driving. For pumping, the rotation drove a large rod connected to a rocking beam at the top of the shaft, converting the wheel's rotary motion into the vertical stroke needed to work pump rods deep underground; for ore crushing, the shaft drove crushing rollers or a set of stamps instead. A wheel fed from below was called 'undershot', one fed from above 'overshot' — the two basic designs used across British mining.

Why it was used

Water power gave a mine a continuous, reliable source of mechanical energy without burning fuel, important both where coal was expensive to bring in and simply as the standard technology available before steam power became widespread and affordable.

Risks & limitations

A waterwheel's power depended entirely on a reliable water supply — a dry summer or a poorly engineered leat could leave a mine's pumps or crushing plant starved of power exactly when it was needed most.

Regional variation

Waterwheels of every scale survive or are recorded across British metal-mining districts; the largest working example anywhere in the British Isles, the 22-metre Lady Isabella at Great Laxey on the Isle of Man, was built in 1854 specifically to keep the mine's shafts pumped dry.
