> In Zurich, for instance, the water coming out of the 100s of fountains you see around town comes from either of these and they are swapped regularly [2]. There are two systems: - The regular system plugged into every house, business and most fountains around the city. - The emergency system, available at a few special fountains designed specifically for emergencies (e.g. they have a hydrant inside them so that they can be used to fill large containers quickly). As far as I know, the systems are entirely isolated from each other, with different springs, pipes and everything. They can't be swapped.

  I can't find any evidence supporting that. I find numerous references referring to the supply as if it was distinct from the normal supply and none that indicate it is in any way connected to the main water supply: - https://www.stadt-zuerich.ch/dib/de/index/wasserversorgung/wasserverteilung/Notwasserversorgung.html https://www.stadt-zuerich.ch/dib/de/index/wasserversorgung/w... (mentions a 150km spring-fed pipeline connected to the emergency wells that requires no energy) - https://skyplan.ch/maps/zurich-water/ https://skyplan.ch/maps/zurich-water/ (mentions "Das separate Quellwassernetz" - "the separate spring water network") - https://www.gemeinderat-zuerich.ch/geschaefte/detailansicht-geschaeft?gId=3fe6d50f-8bbc-42f5-969f-fd14523d04fb https://www.gemeinderat-zuerich.ch/geschaefte/detailansicht-... (mentions "Dieses separate Leitungsnetz") - https://www.alt-zueri.ch/turicum/brunnen/notwasserbrunnen.html https://www.alt-zueri.ch/turicum/brunnen/notwasserbrunnen.ht... (mentions "unabhängigen Notwassernetz" - "independent emergency water network") Can you point to any sources that say otherwise?
