The pump started work in 1813 using the power of the River Avon to lift water up 48ft into the Kennet & Avon Canal above. It is a rare surviving example of the technology of the Georgian Regency period.

When the museum is open, it is well worth stopping off from a canal walk or an exploration of the Limpley Stoke Valley. It is about a 30 minute walk from Dundas Aqueduct along the towpath.
