Crofton Pumping Station, near the village of Great Bedwyn in Wiltshire, England, supplies the summit pound of the Kennet and Avon Canal with water.
However, a set of usable springs were found adjacent to the canal route about one mile (1.6 km) east of the summit pound, and about 40 feet (12 m) below it.
Some years later a reservoir (Wilton Water) was created to improve the supply to this pound, and this can now be seen across the canal from the pumping station.
Water from below lock 60 was taken by a culvert to the foot of a well sunk from the pumping station, which is built on the hillside more than 40 feet (12 m) above the canal.
The water flows along this channel under the force of gravity until it reaches the summit pound about one mile (1.6 km) to the west.
The reduced height chimney was unable to provide sufficient draught for the boiler, and it proved cheaper to retire the steam engines and install electric pumps.
Number 1 engine was first successfully steamed on 4 April 1970 and the pumping station was officially reopened on 21 August the same year by John Betjeman.
While awaiting repair, British Waterways contacted the Kennet and Avon Canal Trust who put Crofton into steam.
