Echuca fluoride system offline
- Echuca
As part of Coliban Water’s regular upgrade and maintenance program, the fluoride system at the Echuca Water Treatment Plant is currently offline while the unit is being replaced.
This means fluoride will not be added to the Echuca water supply until the work is complete.
Fluoride does not contribute to your water’s safety. Your water remains safe to drink.
For more information on why fluoride is added to drinking water and the oral health benefits, visit the Department of Health's website at health.vic.gov.au/water/water-fluoridation. And for other ways to help support dental health, visit health.vic.gov.au/water/unfluoridated-areas
We encourage community members to speak with their dentist or healthcare provider if they have any concerns.
We expect the new fluoride system at the Echuca Water Treatment Plant will be installed by mid-2026.
Planned works at Bendigo Water Treatment Plant
- Bendigo
We are installing a new ultra-violet (UV) disinfection system and chlorine contact tank (CCT) at the Bendigo Water Treatment Plant from late May to mid-late December 2025.
Works will be carried out 7am and 5pm on weekdays.
There will be increase in traffic during this period as vehicles and crews arrive and leave the Bendigo plant each day. This will include cranes, concrete trucks, light to medium trucks and general vehicles.
Some additional truck movements will be to move prefabricated materials onsite. We apologise for the inconvenience. Minor traffic management may be in place.
Completing this project will help improve the water supply that we provide to customers in Bendigo, Huntly, Marong, Axedale, Raywood, and Sebastian.
There will be no disruption to your water supply and your water remains safe to drink

If you live on Hills Road, your driveway will not be blocked, and you will still be able to access your property. A detour will be in pace via Parnell Street and Dorset Drive. Residents in Parnell Street may notice an increase in traffic while detours are in place.
Malone Park Road will remain open to traffic, and you can still use other streets in the surrounding area to access the Calder Highway.
