The equipment upgrades are being made to meet modern standards and will improve the long-term reliability of the dosing systems.
As a result of the upgrades, which will include a new control system and cabling, fluoride will not be added to drinking water until the work has been completed.
Queensland Health has been advised of the temporary water fluoridation suspension to residents of Brisbane, Ipswich, Logan, Redlands and some areas of Somerset and Scenic Rim.
Queensland Health has advised there is no need for the community to take any action with a shutdown of this duration as the dental health benefits of fluoride are achieved and maintained over many years.
Water fluoridation is the process of adding fluoride to a water source so the level of fluoride in the water reaches the recommended level for optimal dental health.
In South East Queensland, fluoride is added to the water supply at a level of 0.8 milligrams per litre in accordance with the Water Fluoridation Act 2008, Water Fluoridation Regulation 2020 and Water Fluoridation Code of Practice 2013.
The plant will continue to supply drinking water to residents of Brisbane, Ipswich, Somerset, Scenic Rim, Logan and Redlands without interruption.
It is anticipated that fluoride dosing will resume in late January 2023.
