Protecting our water supply

Protecting our drinking water catchments

As part of our operations to store and supply  water, we make sure that the catchments that feed the water storages are kept as healthy as possible.  To do this:

Monitoring water quality

Ensuring that high quality water is delivered to our customers is a priority.  Our water is required to meet compliance under the ACT Public Health (Drinking Water) Code of Practice 2007 and the Australian Drinking Water Guidelines 2011.

A comprehensive routine drinking water quality monitoring program verifies the water quality throughout our distribution network.  More than 5,000 routine water samples spanning the entire system from the catchments, to the service reservoirs, through to customer taps in 2012-13. 100% of samples taken from our customer’s taps were compliant with the guidelines. 

Water Storage Levels

Our storage capacity is approximately 278GL (278,000 ML) which is stored in 4 dams: Googong, Cotter, Corin and Bendora.   In comparison, Sydney Harbour holds 500GL of water.  So, when our storages are full, we have over ½ the volume of Sydney Harbour. 

When can I use water?

To help the residents of Canberra and Queanbeyan conserve water, we encourage responsible water use.  This is facilitated through permanent and temporary water saving measures:

  • Permanent Water Conservation Measures
  • Temporary Water Restrictions

The permanent measures exist year round whilst the temporary water restrictions come into force when water levels become lower.
