Another novelty in windmills was the windmill pump, which was erected on Wandsworth Common by a gentleman named William Watson,
in 1815, this was built for the purpose of supplying what was known as the "black sea" pond with water,
the ruins of this mill are still standing (1913) on the railway siding near Trinity Road.
Signboard
says:
The Windmill
Wandsworth Common
This is all that remains of a smock mill
constructed in the 1830s by the London and South Western Railway Company
to pump water from the cutting into a nearby lake known as the Black Sea.
William Wilson, the founder of Prices Patent Candle Company, created a
garden around the lake as part of his estate. The windmill stopped working
in 1870 when the lake was filled in.
This sign was put here to mark the 20th anniversary of the
Wandsworth Society
1991
