English: The Poyle Pump at grid reference TQ034766 on the Bath Road between Poplar Close and Sherbourne Close in Poyle, Slough, United Kingdom. Inscriptions on or near the pump read: 'The Poyle Pump erected in 1827 by the Colnbrook Turnpike Trust. Restored in 1992. Contractor CDR Construction Ltd' and 'This pump was erected by order of "Beau" Nash of Bath in 1754'. I think the 1827 date is more likely (possibly replacing an earlier one erected in 1754). This page at villagepumps.org.uk says:

"The [Colnbrook Turnpike] Trust was responsible for the maintenance of 17 miles of the Bath Road between Cranford bridge and Maidenhead bridge. They erected several pumps along the turnpike, specifically in order to fill water tanks to lay dust. Only two such pumps remain now, one here at Poyle, and one at Longford."

Presumably the water tanks were mounted on the back of horse-drawn carts, which would explain the need for the great height of the pump - nearly 3 metres. (Previous mention of traction engines removed: the first traction engines didn't appear until the 1850s.)
