Drinking water quality
Every day, Gosford City Council supplies around 33 million litres of water to approximately 60,000 properties through 1,000km of water mains.
This water comes from the rivers, creeks and dams in the Gosford and Wyong Local Government Areas. The catchments are largely undeveloped and uninhabited. Council has developed a Water Supply Catchment Area Development Policy to manage and protect the condition of this area and the nature of our source water quality.
The water in our region is considered soft because it is low in minerals such as calcium and magnesium. This is very common along the East Coast of Australia where sandstone and other sedimentary rocks form the areas' topography.
Council moves water from the catchment to our water filtration plant at Somersby, where it is filtered and disinfected to ensure it is safe to drink. Low levels of chlorine are added to protect the water as it travels through the system to your home.
Regular tests on the water supplied to customers are performed by Council and independent National Association of Testing Authorities (NATA) registered laboratories to ensure this water complies with the Australian Drinking Water Guidelines.
Further information on our water supply system can be found on the Living Water Smart on the Central Coast website.
