- Harcourt
The following support is now available for customers in Harcourt following the bushfires that impacted the community on 9 January 2026.
Bushfire Bill Relief Program
| For urban customers in Harcourt who lost their primary dwelling or business | We have waived our entire bill for the billing period early November 2025 to early February 2026. We will waive our fixed service charges for the billing period early February 2026 to early May 2026 (this means you will only pay for any water used on your property during this time). No action is required. These benefits will be applied automatically for eligible customers. |
| For rural customers in Harcourt who access water from our rural pipeline (and who are billed using a different structure) | Impacted customers in the fire-affected area will receive $450 in bill relief, including a $300 rebate off their current bill (received in February 2026) and a further $150 rebate off their next bill (due to be issued in April 2026). These benefits will be applied automatically for eligible customers. Eligible customers may also be entitled to an additional $500 if their primary dwelling was destroyed by fire. Please contact us if you believe you are eligible for this support. |
| Whole-of-community support | Through our Community Rebates Program, we made a $6,000 contribution to the Harcourt Progress Association rebate to support local recovery efforts. This contribution acknowledges the impact of the Do Not Drink Advisory caused by the fires. |

Coliban Main Channel blockage - Sedgwick
- Coliban Main Channel, Sedgwick
Update, Wednesday 1 April
We have successfully installed a bypass pump at Wirths Tunnel, allowing us to continue supplying customers.
This temporary setup allows us to maintain supply while we plan the clearing works for after the rural water season.
Our team is working through existing orders and scheduling and contacting customers.
Final orders for the season can be placed until 2.30pm on Friday 24 April 2026.
About the blockages
A blockage on the Coliban Main Channel caused by debris from the recent fires in Harcourt was impacting our ability to deliver water to parts of the rural network including Spring Gully Channel, Abbotts Channel, Mannes Channel, Emu Valley #1 Channel, Emu Valley #2 Channel and the Coliban Main Channel downstream of Charles Lane in Faraday.
Our rural network provides water to our rural customers for irrigation and stock use. There is no impact to our drinking water networks which supply the towns in our region.
Blockages were identified in Wirths Tunnel near Youngs Lane, Sedgwick, and Byrnes Tunnel near Byrnes Road, Sutton Grange.
Assessing the tunnels
Due to the unknown structural condition of the tunnels and the risks of working in confined spaces and underground, clearing the blockage will take some time.
Structural and safety assessments of the tunnels have been completed to ensure the safety of our staff and the extent of the blockages. These assessments showed the location and extent of the blockages.
The partial blockage in Byrnes Tunnel near Byrnes Road, Sutton Grange was removed on Thursday 26 February.
The Wirths Tunnel blockage will take time to resolve and therefore will be undertaken after the closure of the rural season.
Clearing the blockages
We have worked to provide a temporary supply to customers using a pump to bypass the blockage. This bypass will help fill all water orders placed by rural customers however there may be delays due to the backlog of orders we receive during this time. Our team will be in touch to discuss the delivery of existing orders.
We are considering several solutions to safely and effectively remove the blockage. This will be done at the conclusion of the rural season and may require additional assessment and support from contractors.
We apologise for any inconvenience caused.

Pipeline construction – Maiden Gully
- Maiden Gully
We are continuing construction of the Maiden Gully to Marong Pipeline in Edwards Road and in the easement between Edwards Road and Glenelg Drive in Maiden Gully. Works are also ongoing on the easement between Edwards Road and Rocky Rises Road.
Construction in Edwards Road will continue until late April and will include some traffic management including one lane being blocked at times. This change to traffic conditions helps us complete our work safely.
During peak hours, we will monitor the traffic flow and adjust the traffic management accordingly. Outside of business hours the lights will be run automatically.
Works in the easement between Edwards Road and Glenelg Drive will continue until May with the pipeline joining the previously installed water main that makes up the Maiden Gully to Marong Pipeline.
We may need to temporarily close some sections of the easement during works. This means you may see temporary fencing installed for safety before we start the works.
We will work to reopen sections of the reserve where possible, only closing the areas where we’re working. You will still be able to access your property as normal.
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.
