Pipeline construction – Maiden Gully

  • Maiden Gully

We are continuing works on the Maiden Gully to Marong Pipeline, a new 11-kilometre water pipeline constructed between Golden Square, Maiden Gully and Marong to boost capacity and improve water pressure and reliability in this key growth corridor.

You may notice us working in the power line easement between Edwards Road and Rocky Rises Road and in the easement between Olympic Parade, Maiden Gully, and Emily Way, Golden Square. 

We may need to temporarily close some sections of the easement during works. You will still be able to access your property.

All our works will be completed on weekdays between 7am and 5.30pm.  

Please take care when driving in the area and follow any traffic management that is in place. 

We apologise for any inconvenience.

Boat ramp closed to larger vessels – Upper Coliban Reservoir

  • Upper Coliban Reservoir

The Premier Mine Road boat ramp at the Upper Coliban Reservoir will be closed from 5 January 2026 until further notice to larger vessels that cannot be carried to the water. 

This is due to releases from the Upper Coliban Reservoir that will reduce water levels in the boat ramp area.

Vessels that can be carried to the water – such as kayaks and canoes – are still permitted to use on the reservoir.

This restriction will remain in place until water levels increase at the reservoir.

Please note a blue-green algae alert remains in place at the Upper Coliban Reservoir. Visitors should avoid contact with the water.

Blue-green algae - Upper Coliban Reservoir

  • Upper Coliban Reservoir

Due to increased levels of blue-green algae in the water, Upper Coliban Reservoir is now closed for on-water recreation.

The use of kayaks, canoes and small portable craft is not permitted.

Please avoid making contact with the water. The water is unsafe for humans or animals to consume. Due to this we also advise against shoreline fishing at this time. If contact has been made rinse any contact areas with fresh water.

We have increased our water quality testing program to monitor the situation more closely.

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.
