Drinking Water Quality

Central Coast Council provides safe and reliable drinking water to approximately 63,000 residential and non residential properties across Wyong shire.
Our staff conduct regular water sampling and testing to achieve safe drinking water. This testing and monitoring takes place throughout the water supply system. Samples are taken in the dams, after water is treated, in distribution pipes and at customer taps.
We test for microbiological, physical and chemical components to ensure the quality of our water meets the Australian Drinking Water Guidelines. The data obtained from testing is recorded and analysed. This information tells us whether any change to the treatment of water is needed. 

The quality of water is influenced by a range of factors including: Wyong Water cannot control all of these factors. You can help by looking after our waterways and catchments, as well as maintaining your household pipes and fixtures.


For the financial year ended 30 June 2017, Wyong fully complied with the Australian Drinking Water Guidelines (ADWG).

More information can be found in the Annual Summary of Drinking Water Quality Report.
