Apollo Bay

The coastal towns of Apollo Bay, Marengo and Skene’s Creek experience an influx of visitors during summer, which temporarily swells the population ten-fold to around 20,000. The permanent population is around 2,000 and expected to grow towards 3,000 by 2065.



Our challenge

Apollo Bay’s storages have a total capacity of 375 million litres and annual demand is about 390 million litres.

This limited storage capacity in the system means that it is highly dependent on seasonal climate patterns, with the ability to meet peak summer demand reliant upon having had good rainfall in winter and spring.

We know that the variability in our climate is becoming more extreme with the impacts of climate change. Under a worst-case scenario of high climate change and high population growth, there is an increased possibility of harsher water restrictions, more often and for longer, by 2028.

Our response

While the existing Apollo Bay system can continue to meet service levels in coming years, we will need to act within the next decade to maintain a reliable supply of water over time.

Over the next five years we will focus on the immediate actions we can take to optimise existing arrangements, while preparing for the larger scale augmentation that may be required in the future.

In the next 5 years:


Find more water
  • AB1 Engage with the Apollo Bay community about a preferred long-term option, as part of planning to be ready to implement it when required

Smarter Water Use icon
Smarter water use
  • AB2 Upgrade our infrastructure to maximise efficient production and storage of water
  • AB3 Research use of modular floating covers to reduce evaporation losses
  • AB4 Work with customers to help them use water smarter, such as digital meters to target leakage reduction, and minimise leakage across our network

  • AB5 Work with Colac Otway Shire to progress localised integrated water management opportunities and support uptake of alternative water sources, where efficient

In the next 50 years:


Find more water

Be ready to implement a further augmentation, whether:

  • Small local desalination plant connected to existing water infrastructure
  • Greater use of surface water within existing entitlements

Continue to support uptake of alternative water sources



Smarter water use
Continue to work with customers to encourage sustainable water use, including through innovative technologies

Implement water restrictions to curb demand if total system storage levels fall below defined trigger points

What you can expect:


Actions proposed in the next five years are focused on making best use of water delivered by our existing system in Apollo Bay, as well as establishing what we will do to secure water for the longer-term.

With these actions to optimise our system in place, we expect that water restrictions will be rare in Apollo Bay over the next five years (<5%, or 3 months out of 5 years).
