Did you know?

Our dam levels have dropped 50% faster than in the Millennium drought.

A rain event of around 25 to 30mm over 24 hours would result in a notable increase in inflows.

The Sydney Desalination Plant can supply up to 250 million litres of water a day, which is approximately 15% of Sydney's water needs.
