Operation

Water is transported from the point of water to the reservoir. If the altitude of water is below the altitude of the reservoir, using pumps to lift water up to it.

The water is then sent to a gravity system that will ensure its delivery to all homes.

The pressure of the water supplied to the tap of subscribers is proportional to the height difference between the water level in the water tower and housing: 10 meter drop equivalent to 1 bar pressure, 20 meters 2 bars of pressure, etc.. The largest water towers may contain tens of thousands of cubic meters of water.

History

Antiquity

A water tower converted into a house in Thorpeness , in the English county of Suffolk.

Several major events have marked a challenge to the water towers:

technically, improved techniques for pressurized networks channeling water

;

they provide a pressure constant on the network ^{Element and heritage conversions

Some water towers, spectacular works of art, are now part of industrial heritage.
Others, abandoned, were converted:
in homes , either individually (like a loft ) or collectively (eg for housing );
in observation towers and / or panoramic restaurants , like Goldbergturm (fr) at Sindelfingen in Germany ;
