Why are water towers so tall?

  1. Water towers are tall so that they can provide enough natural pressure to push water down and around their service areas. Each foot of water tower height creates 0.43 pounds per square inch (PSI) (0.029 atmospheres) of water pressure. An average local water supplier usually provides between 50 and 100 PSI (3.4 to 6.8 atmospheres) of pressure. In order to reach all of the houses in a town and provide enough pressure, water towers are normally built tall and placed on high ground. As an added bonus, because of their height, water towers require no moving parts. This way, in the event that the service area's main water pump loses power or breaks down, gravity can continue to supply water to local residents while the problem is being fixed.
