When considering which new water supply sources to invest in it is helpful to understand what matters to the community. For example, is the public concerned about water sources that depend on the weather or unfamiliar technologies? Is there support for the use of non-potable water and other more environmentally-friendly supplies? To gain insight into the public's views, the CRC for Water Sensitive Cities conducted a discrete choice experiment and found that allowed use and supply security are key drivers of community preferences.
