ICE reference number  HEW 57
A steam-powered pumping station built as part of the extensive works to surrounding the construction of John Rennie's Kennet & Avon Canal (1794-1816). It houses two steam engines.
The engines were installed in 1812 and c1900 respectively. They still operate and are demonstrated to the public several times each year.
The older of the two is a Boulton & Watt beam engine with a 42in bore and 8ft stroke. In the UK, it is the only engine of its kind still in situ and doing the work for which it was originally installed.
The more recent engine is an 1846 Sims combined cylinder engine, rebuilt as a single cylinder engine more than 50 years later by its owners, the Great Western Railway. It replaced another Boulton & Watt engine which was actually the first to be installed, in 1809.
The two engines pump water from Wilton Water, 300yd away, to the summit level of the Kennet & Avon Canal -- a distance of three quarters of a mile.
