Is the water always up there?
How does the water get up there? I assume pumps but it all just doesn’t compute in my brain.

To make water reach your house, the water in the pipe has to be under pressure. One way to do that would be to constantly run a pump constantly forcing water into the pipe. But a much cheaper and more reliable way is to just store the water at a height and then gravity will shove that water down into the pipes, keeping them under pressure.
You still need pumps, but all they do is refill that tank by pushing water up into it. Once the water is stored up there, the pumps don’t need to be running to make it run downhill to your house. The pumps only need to run intermittently to refill the tank and keep it topped-off, rather than needing to run 24/7 constantly to force pressure into the pipes leading to the houses.
This also gives you a buffer to help smooth out the demand or withstand temporary power failures. If the power is out for a day making the pumps stop, there’s enough water in the tower for people to still have water until the pumps can start working again. Water supply is considered one of the most important things for a population to have access to in an emergency. As long as people can still drink water and wash themselves, they can deal with being out of power for a bit.
