Water Towers Store Drinking Water

It's true that some water towers store drinking water, but even in those cases, the main function of a water tower is to create water pressure. Most drinking water comes from wells, reservoirs, lakes or rivers. The reason water rushes out when you turn on your faucet is because massive stores of water in vertical, gravity-fed water towers apply enough pressure to force water to flow through your municipality's network of underground pipes leading to your house.
