Water towers use the gravitational head to provide constant pressure. A pump is used to pump the water up to the water tower. If a pump was the only means to provide pressure, the pressure at your faucet would be highly variable. The outlet flow rate of a pump is limited, so it wouldn't be able to keep up with short term fluctuations in water consumption. You could build a pump system that would instantaneously keep up with varying demand, but it would be big and expensive. Instead, a small pump is used to deliver the water to the top of the water tower at a more or less constant rate. When the water is up in the tank, the pressure at the bottom of the water tower is more or less constant, equal to density*gravity*height.

Why arent water towers on the ground?

1). When they're on the ground, they're called water "tanks", not "towers". 2). Water 'tanks' are used to store water until it's needed. Water 'towers' also do that, but in addition, they deliver the water with pressure behind it, since the water starts out at some height, and falls to the place where it's used.

When do water towers release water?

Most water towers are built with two purposes in mind. One is to provide a storage facility for potable water, the other is to provide water pressure for the system. As such, the towers are typically always 'releasing' water. There are normally a couple of one way valves to insure there is no 'backwash' to contaminate the water in the tower, but the tank is providing pressure in much the same way as the tank of a toilet.

Why are water towers very tall structures?

The purpose of water towers is usually to supply water pressure for the distribution of the water, The higher the tower, the higher the pressure. The higher the pressure, the more water you can push through the pipes. Some locations near mountains simply use the pressure of the water in a reservoir located much higher than the community the water is being supplied to. In such areas water towers are relatively uncommon.

Why do old psychiatric hospitals have towers?

Many of the old psychiatric hospitals in the UK were built in remote locations away from centres of population (out of sight, out of mind) and often away from mains water supplies. The towers were often water towers to store water and provide mains pressure to the large populations housed within the hospitals. These towers were often decorated with windows or full gothic decoration to disguise their mundane purpose!
