Key facts
The Swiss Federal Audit Office (SFAO) examined the condition of protected sanitation systems. These are hospitals and underground sanitary installations integrated into care institutions. These installations are aimed at assisting the population in the event of an armed conflict or a disaster. Apart from Israel, Switzerland is the only country to have such infrastructures. The cantons must ensure space in these sites for 0.6% of the resident population. At the end of 2018, 94 hospitals and 248 protected sanitary installations were registered.
