How exactly do water towers work?

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.

Yeah, you use electric pumps to get the water into the tower, and then the tower can provide water pressure throughout the system for free, courtesy of gravity.

Depending on the size and consumption of the water tower, it’s possible to only fill it at times when electricity demand is low and so the power cost will be lower.

But yes, the entire point is to leverage gravity as a free power source.
