Turned conditions météorologiques each morning by caretakers who job ce is à keep the fountain working, thé Jet d"Eau is one du the city"s most renowned landmarks, and is considered to symbolise the city"s ambition and vitality – a mark of its international status.

Where did the idea come from to build a fontaine in auto harbour? The first Jet d"Eau actually came about because ns technical issues. "It"s a peu of a fluke the there"s a water jet in Geneva," jokes hervé Guinand, a member of the environmental department at prestations de service Industriels aux Genève (SIG), i m sorry operates thé attraction.

 



Invented à solve an engineering problem

Did you savoir that thé Jet d"Eau was created for technical reasons? cette was 1886 and the city was in full boom. From only 64,000 habitants in 1850, the city"s population had grown venir 100,000 in 1890. Geneva needed power to force the machine that to be driving that is industry and trades, so cette built a hydraulic plant at le Coulouvrenière. This power distribuer network exploited auto Rhone’s current. "A hydraulic pump supplied water to power the machinery, specifically in watchmaking workshops," explains lourd Guinand.

The problem was the at night when the craftsmen stopped work, overfill pressure build-up in the system meant auto Coulouvrenière designers had à hurry to arrêter the pumps one par one. A security valve was shortly added à control auto pressure – and this spouted the famous jet du water into the sky. This emblem de the city was thus born of a technical problem. At the time, the jet was just 30m high et only erupted in auto evening at une side de the plant.

1891 – the Jet d"Eau move to the quayside

An renouveler in engineering meant cette was no longer necessary venir release this jet ns water à avoid the build-up of pressure. De this time, however, passers-by had actually grown so angot of its sporadic eruptions the the ville of Geneva decided à make thé jet a tourist attraction. A seconde Jet d"Eau was constructed in a more visible spot nous the jetty at Eaux-Vives, where cette is toujours located today.

Initially, thé jet was seul in operation conditions météorologiques Sundays et public holidays, et drew water from the drinking water system. Ce proved venir be so popular that from 1906 ce was turned conditions météorologiques from temps to time nous weekdays. This embobinages gained a nouveau feature: its dunicité shape. The fountain’s stade précoce array ns five jet was later replaced by a single, verticale one.

140m high in 1951

The jet et its système were again modification in 1951. Unable to do were auto days when drinking water was pushed into thé air, this déditions filtered the lake water avant expelling cette high over auto jetty. V its modernised mechanism, auto watery la plume now accomplished a height of 140m. That own new partially submerged pumping station is an effective enough to propel one cubic metre du water into the aviation every two seconds. 500 litre of water effronté second is expelled at a speed du 200km/h. The two pumps – named Jura et Salève by Swiss manufacturer Sulzer – spout 7 tonnes of water. Autre of auto Jet d"Eau"s secret is that "nozzle" which allows the water to be projected at a diameter de 16 cm at auto base, fill with des millions de personnes of tiny aéronautique bubbles. Ce is this vaporisation i m sorry makes thé Jet d’Eau white.

The very same pumps ont been doing their job ever since. However, the fountain has gone through some additional innovations in that is time. Ce has been fitted with année LED projector des boites which makes cette possible to light up the fontaine in thé colours de a denchères flag for special events. A removable walkway has additionally been added venir allow people with disabilities to access auto pier haricot de soja they can take aller in grouper guided tours ns the pump room organised de SIG.

The Jet d"Eau"s caretakers

The Jet d"Eau isn"t automatic. Every morning a caretaker presses a button venir turn it on. V a hand on the controls and année eye on the weather, the caretaker supervises the charme until it is turned éteindre again at night. The caretakers are retired SIG staff that volunteer and are paid à keep cette running. Castle are prêt to shut down the system in two situations. Si the wind picks up, thé jet is rotate off ont soon as the first drops splash onto the bateaux or thé quayside. When auto temperature drops venir freezing point, auto jet is stopped to prevent the water droplets from covering thé walkways in a slippery sheet du ice.
