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.

By gravity and air pressure.
A water tower is like having a bucket of water on top of your house. This bucket has a line coming out of the bottom and is hooked up to your water faucet.
When you turn “on” the water, gravity pulls down on the water along with the air’s weight pushing down too.
The water “flows” to less pressure, so it comes out of your faucet.
As you use up this water in the bucket, it has to be replaced. You could get a ladder and refill the bucket by carrying water to the top of your house and pouring it into the bucket. But this is hard.
It’s a lot easier to “pump” the water up to your roof using a pump and a water hose. A hand pump works but an electric pump works better. This pump has to pump more water up to the roof if the bucket gets too low. This lets the pump “rest” when there’s plenty of water in the bucket.
