ELI5: How do water towers work? How has technology not progressed to make them obsolete?

It's almost the perfect system. You are only dependant on gravity to make it work. No electricity no problem. Gravity has your back. If you have an extended power outage you only have to get external power to the pump at the tower to make sure everyone has water. As bad as hurricanes, snowstorms, etc are if would be an order of magnitude worse if you did not have clean water. Basically let physics do its thing. If the Fukushima nuclear plant had used gravity instead of electricity as an emergency cooling backup then no one would probably know what Fukushima was.
