| Short description: |
EXTRACT: Urban water supplies are traditionally based on limited freshwater resources located outside the cities.
However, a range of concepts and techniques to exploit alternative water resources has gained ground as
water demands begin to exceed the freshwater available to cities. Based on 113 cases and 15 in-depth case
studies, solutions used to increase water self-sufficiency in urban areas are analyzed. The main drivers for
increased self-sufficiency were identified to be direct and indirect lack of water, constrained infrastructure,
high quality water demands and commercial and institutional pressures. Case studies demonstrate
increases in self-sufficiency ratios to as much as 80% with contributions from recycled water, seawater
desalination and rainwater collection.
