N1: The world is increasingly experiencing disruptive events. Long-term planning requires thinking a long way into the future, which is deeply uncertain.

[On-screen visual: animation of fire, flooding, heatwaves and extreme rainfall appears]

N1: Many factors influence how we plan for the future of Melbourne’s Water, sewerage and drainage infrastructure.

N1: As Melbourne's population grows and the climate changes, so does demand on our city’s water and sewerage services.

N1: People use more water to cool off on hot days, which impacts our ability to supply water at the right pressure.

[On-screen visual: animated cityscape during intense rainfall]

N1: When it rains, that water enters our sewer network and with more heavy rainfall events, there is a risk of overwhelming it.

N1: We need to consider the impact these factors collectively have on our services.

[On-screen text: scenario planning, now]

N1: We are using Scenario Planning to envisage how these factors play out through the century under a range of future scenarios.

[On-screen text: Adaptive Planning - Let’s go! Decision / Trigger Point. Route 1, 2, 3. Roadblock. Diversion.]

N1: And adaptive planning to develop strategies that are flexible and can adapt to these future changes. 

[On-screen visual: animation of desktop computer with icons representing planning factors surrounding it]

N1: To help us ensure our system is resilient in the face of future uncertainties and threats Melbourne Water has developed a cutting edge interactive online tool called Network Outlook.

[On-screen visual: close up of Network Outlook dashboard on computer monitor, mouse zooms around website] 

N1: This interactive web map, based on complex modelling, guides us and retailers in planning, developing, and managing our city’s world class water network so it can cope with the demands of our changing world. Using the outlook tool, we can forecast how our water and sewerage networks would hold up to the demands of a changing world under different future scenarios for population and climate change. The tool helps us forecast where we might need future upgrade works or other responses, and where some actions can delay major upgrades. The tool helps Melbourne Water to protect our water and sewerage assets from these potential future risks.
