Crofton Pumping Station, near the village of Great Bedwyn in Wiltshire, England, supplies the summit pound of the Kennet and Avon Canal with water. The steam-powered pumping station is preserved and operates on selected weekends. It contains an operational Boulton & Watt steam engine dating from 1812, making it the oldest working beam engine in the world in its original engine house and capable of doing the job for which it was installed.
