Heritage and history

Timeline take a journey through time button

WaterNSW and its predecessor organisations have been supplying water for over 130 years.

As a result of this rich history, WaterNSW today manages a diverse range of cultural heritage items, including dams and associated infrastructure, weirs, homesteads, regulators and bridges.

The history of Greater Sydney's water supply is a fascinating and often dramatic story as our engineers and city planners worked to adapt to a rapidly growing population and regular droughts ever since 1788.

Dip into our water story with the water supply timeline to journey from early Sydney to the present day.

You can find a full listing of these items which have State or local significance on the heritage and conservation register.

Contact our customer helpdesk if you have any questions or feedback on aspects of our water history.
