Tank Stream, Heritage water stream in Sydney, Australia
The Tank Stream flows beneath Sydney's central business district, extending from Hyde Park to Sydney Cove through a network of underground tunnels.
The stream provided essential fresh water to the first European settlement in 1788, leading Captain Arthur Phillip to establish the New South Wales colony at Sydney Cove.
The Gadigal people of the Sydney region used this freshwater stream for sustenance and gathered resources from its surrounding environment before European settlement.
Sydney Living Museums and Sydney Water organize guided tours through sections of the Tank Stream, allowing visitors to explore the underground waterway.
The stream's name originates from stone tanks carved into bedrock in 1790, which stored approximately 20,000 liters of water for the growing colony.
