Water mains cleaning - Marong
- Marong
We’re carrying out water mains cleaning from 15 to 18 September in Marong.
This cleaning is part of the final works being completed before bringing the new Maiden Gully to Marong Pipeline online.
Some customers in these areas will experience a short water supply interruption, as we clean the water mains in their street. These customers will be notified before the interruption, to allow them time to prepare.
We recommend affected customers turn your stop tap off ahead of air scouring works.

Water tank commissioning works - Guildford
- Guildford
We are in the final stages of bringing the Guildford Clear Water Storage Tank online and connecting it to our network.
To improve water security and reliability, we have redesigned the tank, installed new pipework and pressure valves, and upgraded the Fryers Street booster pump station.
The next step is to energise the booster pumps and commission the Guildford Clear Water Storage Tank. Energising the booster pumps is expected to be completed within the next four weeks, with commissioning works to follow.
Once operational, the tank will improve water security for customers in Guildford and Yapeen, provide more consistent water pressure, and help reduce water main bursts and outages.
If you have any questions, please phone our Customer Support Team on 1300 363 200. For more information, visit https://connect.coliban.com.au/guildford-clear-water-storage-tank
On-water recreation reopens at some reservoirs
- Kyneton, Malmsbury and Harcourt North
The following access points have re-opened as of 13 August 2026 after closing due to recent rainfall and a high-level of flows:
- Lauriston Reservoir
- Upper Coliban Premier Mine Road
The following access points remain closed
- Malmsbury Reservoir

These closures help keep the public safe following wet conditions and high amounts of in-flows to the storages.
We appreciate the community's understanding and cooperation while these temporary closures are in place.
Upper Coliban Reservoir – access point closure

We will continue to monitor conditions and provide updates if there are any changes.
Safety reminders
- Do not launch boats or other watercraft from the dam wall area.

We thank the community for helping keep this area safe while the reservoir is spilling.
Water Reclamation Plant controlled releases - Kyneton
- Kyneton
We have started controlled releases of recycled water from our Kyneton Water Reclamation Plant into the Campaspe River as of Thursday 4 June.
Releases to the Campaspe River are required to maintain storage levels in the onsite lagoons and are in accordance with flow and quality requirements of our EPA licence. The releases are weather dependent and will likely continue until September.
Under our EPA issued operating licence for the Kyneton Water Reclamation Plant, we make available to the public water quality and flow monitoring. The flow data, available one month in arrears and updated on the 21st of each month, can be viewed here.
