Interesting Facts on the Water Fountain of Geneva

The Jet d'Eau is a large fountain in Geneva, Switzerland and is one of the city's most famous landmarks


it wasn’t a fountain at all and at first, it only spouted water 30 metres high.

The first Jet d'Eau was installed in 1886 at the Usine de la Coulouvrenière, a little further downstream from its present location.

It was used as a safety valve for a hydraulic power network and could reach a height of about 30 metres (98 ft).


Geneva authorities decided to turn it into a tourist attraction and moved the valve to its current position

In 1891, its aesthetic value was recognised and it was moved to its present location to celebrate the Federal Gymnastics Festival and the 600th anniversary of the Swiss Confederation when it was operated for the first time.

In 1891, with the move, the water fountain was connected to the drinking water system and the water flow increased so the spout climbed to 90m. (295 feet)


The present Jet d'Eau pumps lake water instead of city water

In 1951 the fountain reached its current maximum height of 140m after it was connected to a new pumping system that took water directly from the lake.

500 litres per second

Some 500 litres per second of water now flows from the jet, at a speed of 200 kilometres per hour.

At any given moment, there are about 7,000 litres (1,800 US gal) of water in the air.

Unsuspecting visitors to the fountain—which can be reached via a stone jetty from the left bank of the lake—may be surprised to find themselves drenched after a slight change in wind direction.

White Colour !?

Tubes in the specially designed nozzle disperse air into the water, turning it into bubbles and creating the fountain’s white colour.

800,000 CHF

It costs around 800,000 francs a year to run. (almost $1 million)

Located at the very heart of the harbour area, the Jet d’eau is the emblem of the City of Geneva and its main tourist attraction. It is an integral part of the landscape and occupies a special place in the locals’ hearts.


Marking different days or celebrations

The Jet d'eau is regularly lit up in a wide range of colours to mark different days or celebrations, a sign that Geneva and the SIG are actively involved in these events.
