Elevated water storage tanks are used to store water for fire protection and potable drinking water within a designated area or community. Elevated tanks allow the natural force of gravity to produce consistent water pressure throughout the system.

Why are water tanks raised?

The primary function of water towers is to pressurize water for distribution. Elevating the water high above the pipes that distribute it throughout the surrounding building or community ensures that hydrostatic pressure, driven by gravity, forces the water down and through the system.

Why are tanks placed on top of buildings?

Storage tank of a building is kept at top to store energy as potential energy and we know that potential energy is directly proportional to height. Thus, storage tanks are usually kept at rooftop in order to have easy water flow and so that we do not need any external input to access water at low level.
