| Summary/Abstract |
Cities in drought-prone regions of the American West and Australia provide examples of innovative approaches to utilizing local water resources to achieve more resilient water supplies. Geographical realities, population growth, and favorable economic conditions can create the impetus for investments in new technologies, while support by activist groups and NGOs can encourage more sustainable approaches using locally sourced water. New approaches–whether desalination, stormwater use, water recycling, or potable reuse–share a common path to mass adoption. After a period of piloting and demonstration-scale projects, water providers with few options become early adopters of new technologies. And after the early adopters have gained experience and have used it to support the new approaches, the costs and risks of failure decrease for other providers. Thus, a wider cross section can adopt the new approach. The pioneering projects described herein are the first stage of the reinvention of our urban water systems.
