  • Statement of significance
    Allawah Reservoir (WS 1) is a relatively late example of a rectangular or irregular shaped concrete reservoir with walls supported by slender concrete triangular buttresses. Nonetheless Allawah Reservoir (WS 1) and its associated pumping station (WPS 123) are important for the role they have played in extending the supply of Warragamba water into the Woronora System. The listing includes the reservoir and all associated pipework, valves and valve houses to the property boundary.

  • Physical description
    Allawah Reservoir (WS 1) is a relatively late example of a rectangular or irregular shaped concrete reservoir with walls supported by slender concrete triangular buttresses. Other earlier examples include Waverley Reservoir No.3 (WS 134), 1938 and Wahroonga Reservoir No.3 (WS 125), 1937. Standard features include: tubular handrails and concrete roof over buttress section.
  • Modifications made
    The reservoir has been roofed to safeguard water quality (1960s-1970s).
  • History
    Allawah Reservoir (WS 1) was built in 1958 in response to a decision in the early 1940s to extend local storage to the southern suburbs. Work commenced on construction in 1946, but was not completed until 12 years later. Allawah Reservoir (WS 1) was well placed to take over supply of the lower areas originally supplied by Penshurst and Wiley Park. With plans to extend the Woronora Pipeline to the Metropolitan System, a Main was commenced in 1958 from Penshurst to Allawah. However by 1961, it was realised that instead of Woronora supplying Sydney, the opposite would be the case, with Warragamba water supplementing areas supplied by Woronora. This situation required further amplification of the mains between the Pressure Tunnel at Ashfield and the Penshurst Reservoirs, including a new main from the Pressure Tunnel to Allawah, pumped by a new pumping station in Canterbury Park, together with a pumping station at Allawah to pump water to Penshurst. Completion of this scheme in 1969 allowed Warragamba water to be fed into the Woronora Pipeline in sufficient quantity to assist in the supply of Sutherland, Cronulla and beyond.
