Expert assessment of the resilience of drinking water and sanitation systems to climate-related hazards

To plan for and reduce the impacts of climate change on water and sanitation systems, studies have assessed the resilience of water and sanitation technologies to climate-related events.  However, to date, all studies report qualitative resilience ratings of ‘high’, ‘medium’, and ‘low’.  We obtained expert opinions, in the form of numerical scores, on the resilience of ten drinking water and five sanitation technologies to six climate-related hazards. Resilience scores ranged from 1.7 to 9.9 out of a maximum resilience of 10, with some technologies showing substantially different resilience for different climate hazards. The results of this study help communities in deciding which technologies are best suited for the climate-related challenges they face.
