Probably never. The tunnels cost a lot to build but, once built run almost for free - they're powered by gravity and will keep running for close to a century before major maintained is needed.
- zhivota 9mo agoYeah that makes sense but if growth dictates another tunnel... And it takes another 60 years, your capital expense starts to look a lot like an operating expense. Not to mention one of the big stated purposes of this tunnel is actually to facilitate maintenance of the other tunnels. There is probably more operation cost hidden here than seems obvious.
- cguess 9mo agoThe big reason for tunnel 3 isn't new population growth, it's so that the other tunnels can be shut down for maintenance and inspection. NYC's population is more or less stable over the last 90 years.
- margalabargala 9mo agoClose to a century? There are Roman aqueducts in continuous operation for two millenia.
- llbbdd 9mo agoAFAIK there is one still in operation and entirely for tourist purposes
- margalabargala 9mo agoToday as in Ancient Rome the aqueduct terminates at fountains. It does not connect to the standard modern municipal plumbing. Whether that counts as being operated for "tourist purposes" is a matter of definition. https://en.wikipedia.org/wiki/Acqua_Vergine https://en.wikipedia.org/wiki/Acqua_Vergine
