Nepean Dam, Concrete-face rock-fill dam in New South Wales, Australia
The Nepean Dam rises 82 meters high and stretches 216 meters across, featuring a design that incorporates large sandstone blocks embedded within concrete structures.
Construction of the Nepean Dam began in 1926 under engineer Ernest Macartney de Burgh and reached completion in 1935 as part of the Upper Nepean water supply scheme.
The dam complex includes residential cottages built across different periods, reflecting the evolution of infrastructure management and staff accommodation needs through the decades.
The reservoir created by the dam captures water from a 319 square kilometer catchment area, providing essential water supply to Sydney, Macarthur, and Illawarra regions.
The dam's infrastructure expanded in the 1960s with the addition of connecting tunnels, enhancing water distribution efficiency across the regional network.
