Planned works - Castlemaine Water Treatment Plant
- Chewton
Over the coming weeks we will be working at the Castlemaine Water Treatment on McCay Reservoir Road on Saturdays as part of the construction of our new clear water storage tank.
This is to install the steel walls on our new 6 megalitre clear water storage tank. These works should not involve heavy machinery, extra noise or regular traffic on McCay Reservoir Road.
When completed, the tank will provide extra water security for the Castlemaine community, who rely on the plant to provide them with drinking water each day.
Works will begin on Saturday 16 May and will continue for about 9 weeks, weather permitting. Works will take place from 7am to 3pm on Saturdays. We may not be required to work every Saturday.
Please be aware of extra traffic in the area.
If you have any questions please call 1300 363 200.
Routine maintenance – Cohuna Water Reclamation Plant
- Cohuna
We’re carrying out routine maintenance on one of our lagoons at the Cohuna Water Reclamation Plant.
Machinery will begin arriving on site from Monday 25 May, with works starting shortly after. The works will involve removing solids that settle in the lagoon over time as part of the sewage treatment process. This maintenance will improve our routine operations at the plant.
During the 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 as we transport material from the plant. We expect around three to four truckloads per day.
We don’t expect these works to cause odour, but if you do notice it smells worse than usual or you have any other concerns, please call us during business hours on 1300 363 200.
Your sewer services will not be impacted during these works. Thanks for your understanding while we complete this routine maintenance.

We’re completing routine water mains cleaning between Tuesday, 26 May and Thursday, 2 July 2026 in Maiden Gully, Long Gully, East Bendigo, Ascot, White Hills and Bendigo Central.

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.

Between April and June, we'll be doing site preparation and upgrading underground pipes. We'll be working on weekdays between 7am and 5.30pm.
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.

Echuca Water Tower
- Echuca
Update Tuesday 26 May 2026
With the Echuca Water Tower no longer part of Echuca’s water supply, we’re preparing for the next stage – the careful and safe removal of the structure. This is a large and complex project, with works expected to start from Tuesday 9 June and continue through to late-November 2026.
Pedestrian exclusion zones, traffic management, and temporary road closures will be used to ensure safety.
If you're passing the tower, you may see signage and additional temporary fencing. Please follow any instructions provided to ensure your safety.
What to expect next?
Initial works will involve the removal of nearby power lines and the installation of additional footings at the base of the tower. A freestanding scaffold structure will then be built to assist with the removal of the tower.
