Aspley Reservoir
Please note: Temporary disruption to fluoride dosing at Mount Crosby Water Treatment Plant due to structural failure of equipment. Some areas of Brisbane including Logan and Ipswich will not be receiving fluoride in their tap water. It is expected to be back online in June 2025. Fluoridation is continuing at our remaining 21 water treatment plants. The water remains safe to drink.
