The cellar is of historical significance in that it relates to the caretaker's house, to which it is
probably contemporary, although it may even be earlier. The house has been assessed as of
contributory historical significance to Preston Reservoir, and the Yan Yean water supply system
as a whole, as an original component of the Preston complex.
The cellar provides evidence of the domestic arrangements at the caretaker's residence, but
removal of the deposits within the structure has reduced its archaeological potential as little
information remains to be derived from the structure itself.
