Water Quality

At Icon Water we support and protect our community and the environment by providing safe, clean drinking water.

We do this by implementing the Australian Drinking Water Guidelines (ADWG, 2011) framework and the Hazard Analysis and Critical Control Point (HACCP) risk based management system. These standards combined, assist in the prevention of biological, chemical, and physical hazards to our water supply.

We have a series of checks and balances in place within the water life cycle that ensure water is clean and safe – from extracting water out of a dam to when it enters customer property.  All water quality analytical work is performed by a NATA (National Association of Testing Authorities) registered laboratory. The ACT Public Health (Drinking Water) Code of Practice (2007) and the ADWG govern Icon Water's water quality operations and monitoring.

Icon Water publishes an Annual Drinking Water Quality Report which is a valuable resource for information on the Canberra drinking water supply system and for recent data on the physical and chemical composition of Canberra's drinking water.
