Sydney Water’s Potts Hill Reservoir and Water Pressure Tunnel have serviced Sydney since the mid 1920s. The
Potts Hill Water Supply Reservoirs were an integral part of the Upper Nepean Water Supply Scheme, which was
crucial to the development and growth of Sydney, from the late nineteenth century. The construction of the Reservoirs was a major achievement in hydraulic technology and associated construction methods at the time. In: steel Australia, vol. 32, no. 1, p. 30.
