Lorne

Share on Facebook Share on Twitter Share on Linkedin Email this link
As a popular holiday destination, Lorne’s permanent residential population of around 1,750 people swells to up to 18,000 each summer. This means that water demand is at its peak each year during the months when rainfall and stream flows tend to be lower.


Our challenge

Lorne's storages have a total capacity of 215 million litres and annual demand is about 340 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 system 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 2027.

Our response

We will need to act within the next decade to maintain a reliable supply of water in Lorne over time.

Our actions over the next five years will focus on incrementally saving or sourcing more water to help delay a major upgrade, which will also give us greater flexibility to respond to evolving conditions, as part of an adaptive planning approach.

In the next 5 years:

  • L1 Engage with the Lorne community to help identify a preferred long-term option, so we can continue planning and be ready to implement when required

  • L2 Pursue greater efficiency at our water treatment plant
  • L3 Explore potential water treatment upgrades to maximise the efficient use of water in storage
  • L4 Work with customers to help them use water smarter

  • L5 Work with Surf Coast Shire to progress localised integrated water management opportunities and support uptake of alternative water sources, where efficient

In the next 50 years:

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

What you can expect:


The actions we propose over the next five years in Lorne are focused on optimising current arrangements, maintaining a preparedness to respond to emergency and future conditions, and preparing for a future upgrade, given that it will take time to ensure we are ready to implement a preferred solution when it is required.

With these actions in place, we expect water restrictions will be rare over the next five years <5%, or 3 months out of 5 years.
