Residential customers » Water quality » Fluoride


Fluoride is added to water supplies as directed by the Victorian Government.

Geelong's water has been fluoridated since June 2009. Colac's water has been fluoridated since 2010. Other areas are not currently connected to a fluoridated water supply.

Fluoride protects teeth against decay. Major water supplies have included fluoride in for many years with no harmful effects.




Fluoride is added to reach an optimum dosage of 1 part per million (1 milligram per litre).

Water fluoridation at this level is safe and effective. It has been practised for more than 50 years in Australia and worldwide. The National Health and Medical Research Council (NHMRC) has determined the safe concentration of fluoride in drinking water based on health considerations. This is published in the Australian Drinking Water Guidelines.

The addition of fluoride to drinking water supplies is carefully controlled and monitored.




Our customers do not  pay more to receive fluoridated water.

The construction costs of our fluoridation plants were met by the Department of Health.



Taste, smell and colour

The addition of fluoride doesn't change the taste, smell or colour of water.

Fluoride is a naturally occurring element in water, and the addition of this amount is not noticeable.


Our position on fluoride

Barwon Water's Board of Directors agreed that fluoride is a safe, beneficial, community-wide dental health measure.

The Board considered a diverse range of views, including the compelling evidence from medical, health and dental experts.

In particular, the Board noted fluoride has been in major water supplies in many areas for many years without any recorded harmful effects. This includes the Melbourne metropolitan area where more than 3 million people have had access to fluoridated water for more than 30 years.
