I believe city water pressure will take it to the 5th floor and that is gravity driven.
I live on the 2nd floor and never lost water pressure during the two major blackouts NYC suffered in the past 20 years while the higher floors in my building did once the roof tank was emptied.
- falcolas 4y agoYes, the water that comes to your apartment is fed by gravity from a holding tank situated at a higher elevation than you. But getting the water that high depends mostly on electric pumps. Even if the source is higher than the water towers, there are open cisterns for water treatment between the source and tower. And those pumps and treatment plants have backup generators and priority on gas deliveries for them.

- JackFr 4y agoNope. With respect to NYC I believe you’re mistaken. 97% of NYC water is gravity fed from three reservoirs. https://www.nyc.gov/html/nycwater/html/drinking/reservoir.shtml https://www.nyc.gov/html/nycwater/html/drinking/reservoir.sh... “The NYC Aqueduct is a pressure tunnel (a gravity feed system) with hydraulic head provided by a 300 m difference in elevation between the watershed headlands in upstate New York and the distribution area (NYC). The head is enough to get water under pressure to the sixth floor of most buildings without pumping.” https://sites.hofstra.edu/charles-merguerian/a-history-of-the-nyc-water-supply-system/ https://sites.hofstra.edu/charles-merguerian/a-history-of-th...
