We are looking at all the options to manage water in the Macedon Ranges.
We’re working to make sure we’re prepared to have enough water in a dry period, and manage extra water when it’s very wet. This includes finding the best ways to use our recycled water, which is always in strong supply.
We have been talking to the community since late 2022 to build a shared understanding of preferences and values towards water management in the Macedon Ranges.
Greater Western Water (GWW) worked alongside consulting group RPS to design and deliver the engagement program, to support GWW's understanding of community priorities.
The community identified ten priorities for water management in the region including maintaining healthy waterways and habitats.
We will be using your feedback and these values for future works, planning, and community consultation.
To ensure you are kept up to date on any future works, please subscribe to our newsletter via the link below.
We're considering other projects that enhance the environment and local liveability and we want to hear what is important to you.
We will be back with more information in 2024.
Most of the water used by the Macedon Ranges community comes from rainfall.
But after the water has been used, it becomes wastewater. It flows into the sewerage network to our recycled water plants, where it’s carefully treated.
Wastewater is always in plentiful supply in all communities, because people always need to go to the toilet, stay clean, and use water in other ways. As populations grow, this supply increases – even if individuals are careful about their water use.
We have listened closely to community values and priorities, and we will factor this into our next round of planning, to help find feasible solutions that will work for the Macedon Ranges community and environment.
This consultation phase will also help us understand if there’s any additional information the community would like from us.
Climate change will increase the impact of these challenges with Victoria becoming drier over the long-term, with more extreme events including droughts, floods and heatwaves.
Rainfall will decline. The Victorian Government predicts that by 2065, water flowing into some catchments could reduce by around 50% per year. This means less water will be available water in storages.
However, we’re also likely to see more intense storms, which can cause a range of other storage, management and demand issues.
As the Macedon Ranges grows, we will have more wastewater to treat, and more recycled water to manage.
In 2021, we treated 11.9 billion litres of sewage in the Macedon Ranges. Of this, 5.3 billion litres was used by customers, leaving us with another 6.6 billion litres to manage.
We’re looking at what we can do to upgrade our services, explore ways to find more recycled water customers, and find other sustainable solutions, to make sure we’re prepared for a range of scenarios. Your feedback will help us find solutions that will best meet the needs of the community.
If possible, it is stored on site.
Gisborne, Riddells Creek and Woodend recycled water plants have a licence from the Environmental Protection Authority to discharge excess volumes into a nearby creek under strict conditions.
The Romsey plant currently does not have an ongoing discharge licence. Typically, excess recycled water from Romsey is trucked to nearby recycled water plants (usually Riddells Creek and Gisborne).
During sustained heavy rainfall we may conduct a temporary discharge of controlled amounts of water. Where this happens, we work closely with the EPA and monitor closely for any impacts to human and environmental health.
Sustained heavy rainfall and ongoing wet weather conditions sometimes result in a significant rise in the amount of water stored at a recycled water plant.
If the plant has a discharge license, we may release controlled amounts of recycled water to a waterway. If the plant does not have an ongoing discharge licence, we will notify the EPA and undertake a necessary temporary release, monitoring closely for any impacts of this release on the environment or human health.
Discharging excess recycled water from storage helps to reduce any potential for uncontrolled overflows and protects the recycled water plant infrastructure to continue providing an essential service to the community.
There are four recycled water plants in the Macedon Ranges, each operating slightly differently. Take a look at our interactive map and find out more.
There are three classes of recycled water. Recycled water produced in the Macedon Ranges is Class B and C.
Underground sewers carry sewage from toilets, showers, laundry sinks and kitchen sinks to a centralised wastewater treatment plant for treatment and disposal.
Your property connects to the sewer network via your house connection drain and our sewer main.
