  • Physical description
    Coledale Reservoir (Break Pressure Tank) (WS 29) is a circular riveted steel plate reservoir. Standard features include: concrete apron, handrail in tubular steel, access ladder, davit, inlet and outlet valve chambers and a trigonometric station. It is unusually small in size. Full Service Level: 73 m. Capacity: 0.67 ML. A pumping station is located on the same site.
  • Modifications made
    The reservoir has been roofed to safeguard water quality (1960s-1970s).
  • History
    The Metropolitan Water Supply & Drainage Board initially used water from the Cordeaux River, the nearest of the Upper Nepean tributaries to supply the South Coast, Wollongong and its suburbs. A series of dams were constructed on the Cordeaux River, the principal dams being completed in 1903, 1915 and 1926 respectively. Because of the height of the ridge (O’Briens Gap) above the coastal area, pressure in the trunk main was too high to be directly connected to reticulation mains. The pressure was broken down by the construction of 5 service reservoirs at the highest points on the coastal plain. The initial supply scheme from the Cordeaux River to Wollongong was constructed by the NSW Department of Public Works in 1902-1903. It was transferred to the MWS&DB in 1903. The second major stage of development occurred in 1909 with extension to Port Kembla and Unanderra. The third stage of expansion was completed in 1915 with water supplied to Figtree, Mount Kembla, Kembla Heights, Mount Keira, Keiraville and towns to the north of Wollongong, namely Balgownie, Corrimal, Bellambi, Russell Vale, Woonoona, Bulli, Thirroul, Austinmer, Coledale, Scarborough and Clifton. The extensions of supply to Dapto in 1920 and to Mount Drummond (now Mangerton), Tarrawanna, Reidtown, Fern Hill and Fairy Meadow, all in 1922, were supplementary to the third stage of expansion. Since that date, expansion has occurred in all of the South Coast water supply, although Kiama, Jamberoo and other southern areas were not connected to the Avon supply until after 1961. In the 1960s, supply was made available from Avon Dam, this dam being originally completed in 1928. Water is now supplied from Avon Dam, via filtration plant, to Mount Keira, Berkeley and Dapto, from whence all other reservoirs receive their supply.
