The water pump probably dates from early 1900's and goes into a
trough known as a lavoir. Lavoirs are public washing places which
replaced the use of local streams for such purposes. Local people
would have be bound by specific agreements covering their use of
the lavoir as of course water sources were carefully guarded as
whole areas might rely on the same stream or spring for all their
needs
