Pressure Tunnel and Shafts, Water supply system in Potts Hill, New South Wales, Australia.
The Pressure Tunnel extends 16 kilometers from Potts Hill Reservoir to Waterloo pumping station through two cylindrical tubes measuring 1.8 meters in diameter.
Construction of the tunnel began in 1921 and faced multiple engineering challenges, including rupturing of the lining, leading to a Royal Commission investigation in 1933.
The tunnel represents a significant advancement in civil engineering practices of the early 20th century, influencing future water infrastructure developments in New South Wales.
Seventeen shafts along the tunnel route provide essential access points for maintenance and dewatering operations, ensuring continuous water supply to Sydney metropolitan area.
This water supply system ranks as the third largest pressure tunnel globally, utilizing steel linings with concrete protection to prevent internal corrosion.
