Water Pressure

Why are many water towers placed on high towers?

The height of the water determines the pressure. Since a holding tank is up high, it places a lot of pressure on the water in the rest of the water network. The tank should be as large across as possible so that for the same amount of water the vertical dimension of the tank can be as small as practicable. This design limits the variation in pressure as the tank empties or is filled.
