Geneva’s emblematic Jet d’eau. A story. A symbol

One of Geneva’s most well known symbols since 1891, the Jet d’eau (water jet) epitomizes the ambition, dynamism and international renown of a city that respects the environment and always looks ahead.
As the owner of this liquid monument, SIG keeps it fully maintained all year.

Once upon a time there was a water jet…

Like most great inventions, the Jet d’eau was actually created by accident.
When Geneva’s artisanal hydraulic power machines stopped being used, a valve designed to relieve over-pressure by letting water escape created a 30m jet towards the sky.

In 1891, Geneva City Council decided to turn the water jet into a tourist attraction and moved it to the end of the jetty in the port of Eaux-Vives. Connected to the drinking water network, the 2nd water jet was born - climbing to 90m.
In 1951, new waterworks built to use the lake allowed the jet to reach 140m.

It’s beauty secret

The secret to propelling such a huge torrent of water into the sky is in the pipes.
A special tailpipe projects a tube of water measuring 16m in diameter and another pipe fills it with millions of air bubbles to create its magnificent white colour.

The guardians of the Jet d’eau: a magical job!

Geneva’s Jet d’eau is looked after by five retired volunteers from SIG. Their eyes and experience are indispensable. If the temperature drops to around zero or there’s a slightly strong wind, the Jet d’eau has to be stopped.

Colouring the water brings a spectacular edge to the city’s symbol, which often takes centre stage at Genevan festivals and events.
