Persian water wheel is a device used to raise water out of well and mine. It is a system of a chain of buckets slung round a vertical wheel, which is turned by a system of cogs and interlocking wheels powered by an ox or bull driven in a circle. With the passage of time the wooden wheel is replaced by metal. Now a days Persian wheels are replaced by tube-wells, but still they exist in small numbers in northern areas of Pakistan including district Swabi and Mardan.
