Contents: The 12 exercises under Top-down approach in the tool will allow you to produce the following outputs: - Range and scale of exposure and sensitivity of your assets including water and wastewater facilities, machines and equipment, to extreme weather events such as storms, floods and droughts; - Indicative trends and likely amounts of water lost (or gained) due to variability in precipitation, both current and projected, from surface and ground water resources; - Indicative trends in concentration of salinity in your existing ground water resources, both current and projected; - Range of adaptation options and technologies that you can deploy; - A communications strategy that will enable you to pursue a continuous dialogue with your principal stakeholders; and - A final implementation plan that you will need to action. The Bottom-up approach endeavors to elicit similar outcomes through the outputs below: - Critical climate variables and the water utility’s sensitivity to these; - Water system responses to a range of potential climate changes; - Vulnerability of the water utility to climate change impacts; - System performance according to the uncertainty associated with climate change factors driving the water utility’s vulnerability; and - Overall system risk analysis and areas in need of further analysis.
