Climate resilience

Discover our plans for dealing with climate resilience and our water. 

Why climate resilience is important

Projections for Melbourne are for a hotter and drier climate with more frequent extreme events. Because our climate is changing, we need to make sure our business is resilient to these changes.

The least hot, wettest scenario represents the 10th percentile change of rainfall, the mid-case represents the 50th percentile changes of temperature and rainfall, and the hottest, driest scenario represents the 90th percentile change of temperature and 10th percentile change of rainfall. Climate data are from gridded BoM data for 1976-2005 and (partial) analogues for the three scenarios are based on current climate matches to the projected annual maximum temperature (+ 1.0C) and annual precipitation (+15%)

What we are doing about it

We are working to identify risks associated with climate change so that we are well prepared to withstand and respond. We are forming alliances with peers to develop tools and knowledge. This means:

  • Working closely with the Water Services Association of Australia and Melbourne’s other urban water companies.
  • We have developed a risk register based on our existing risk management framework.
  • Developing and implementing an Integrated Water Management Strategy to diversify water supply sources

We will ensure we play our part in global efforts to mitigate climate change through our Energy Management Plan. To minimise the health aspects associated with climate change we will work with stakeholders through our Greening the West Program.

How you can track our performance

We have a number of performance targets that are affected by the climate listed in our annual report, including:

  • Unplanned water supply interruptions (per 100km).
  • Water main breaks per 100km of water main (No.).\
  • Safe drinking water standards.
  • Recycled water targets.
  • Reliability of sewerage collection services.
  • Biosolids Reuse.
  • Sewage treatment standards.
