How can there be functioning bathrooms in high rises? (self.explainlikeimfive)

It seems like such a huge amount of water and would require so much energy to get it that high, plus there's the waste to deal with

It still has to pump it the elevation though?

Yes.

Take New York for example. It is my understanding that New York's municipal water system has enough pressure to pump water 5 stories high, so many of the relatively smaller buildings have large wooden water tanks on their roofs to keep that building's water pressure relatively constant even during peak demand times. Larger buildings are responsible for pumping their own water hundreds of feet into the air.

Yes, but multiple tanks throughout the building means they don’t have to pump all the water all the way to the top. They only need to pump the water for the highest floors to the top.

Ah, thanks for the clarification. That makes a lot of sense.
