Water treatment plant upgrades - Cohuna
- Cohuna
We are upgrading the Cohuna Water Treatment Plant as part of our Water Treatment and Storage Upgrade Program, a $40 million program of upgrades across our service region. Upgrades will include replacing the pump station, electrical upgrades and improvements to water treatment processes at the plant.
Between July and September, start construction on the new Powdered Activated Carbon dosing system, Ultraviolet disinfection buildings and wash water handling facility upgrades.
We'll be working on weekdays between 7am and 5.30pm with some low impact works on some Saturdays.
No interruptions are planned as part of these works, but some customers may notice minor pressure fluctuations as testing is carried out.
During works you may notice noise and dust. We’ll aim to reduce this by wetting down the site where possible to reduce dust. You may also notice more trucks in the area using the plant entrance on Cohuna Island Road.
There will be no interruption to your water services as part of these upgrades.

Echuca Water Tower
- Echuca
Update Thursday 13 August 2026
With the Echuca Water Tower no longer part of the town’s water supply, we have moved to the next stage - the careful and safe removal of the structure. This is a large and complex project. Works began on Tuesday 9 June and are expected to continue through to late-November 2026.
Because of the tower’s location, temporary road closures are required and in place on parts of High Street and Pakenham Street near the site. These closures began Monday 15 June and are expected to remain in place until late-November.
Works are being carried out Monday to Friday between 7am and 6pm, and occasionally on Saturdays between 7am and 3pm.
Pedestrian exclusion zones, traffic management, and temporary road closures are in place to ensure safety.
If you're passing the tower, you may see road closures, signage and temporary fencing. Please follow any instructions provided to ensure your safety.
Initial works involved building a freestanding scaffold structure to assist with the removal of the tower. Internal scaffold and supports have also been installed and the steel roof structure and the external ladder have been removed.
The tower is being deconstructed using a crane and concrete cutting techniques to carefully dismantle the tower in sections. Concrete concrete cutting, core drilling and removal began in early August.
We are limiting noise, dust, and inconvenience wherever possible, while keeping our team, contractors, and the community safe.
What to expect next?
The lower part of the tower's tank section is currently being carefully dismantled and safely lowered to the ground for crushing and recycling.
Once the tower has been reduced to its lower two levels, the remaining structure will be demolished using traditional demolition techniques and removed from site.
The project will then move to foundation removal and site reinstatement works.

Coliban Main Channel blockage - Sedgwick
- Coliban Main Channel, Sedgwick
Update, Friday 31 July
We have now completed the works to clear a blockage in Wirths Tunnel near Youngs Lane in Harcourt North. This blockage was caused by debris from the Harcourt bushfires being washed into the Coliban Main Channel.
Debris removed from the tunnel has been stockpiled near the intersection of Youngs Lane and Leanganook Track. This material will be removed from the area, with full site reinstatement to follow when weather conditions permit. The track remains open for users. Please take care and follow any signage or instructions when travelling through the area.
If you have any questions, please call us on 1300 363 200.
Earlier
