Council's dedicated water treatment process ensures that the water reaching the community is of high quality and safe to drink.
The treatment and filtration processes can be different at each water treatment plant to suit the quality of the incoming water.
Incoming water is filtered with fine mesh screens to remove debris such as like twigs and leaves.
pH levels of the water are adjusted to aid the filtration process.
A solution (coagulant) is added that makes the smallest particles ‘stick’ together to form larger ‘flocs.’ This makes it easier to filter them out.
Filters made of tightly packed beds of sand and crushed coal are used to trap and remove the flocs. Filters are cleaned several times per week and performance is continuously monitored.
The pH of the water is carefully rebalanced or neutralised.
Small amounts of chlorine are added to protect the water from harmful pathogens all the way from our treatment plant to your tap.
As a final step, small amounts of fluoride are added to the water as a safe and effective way of preventing dental decay. This is not part of the filtration process, but is completed under the advice of NSW Health.
Water is disinfected to kill any disease-causing microorganisms. Chlorine is a highly effective disinfectant. It is used at the treatment plant and a residual concentration is left in the water to help guard against microbial contamination from the pipes to your drinking tap.

Fluoride is added to community water supplies to reduce incidences of dental decay, particularly in children. Adding fluoride to drinking water is provided for in NSW legislation and is strongly encouraged by NSW Health. Refer to the NSW Health Fluoride Fact Sheet for more information.
