Geneva's Jet d'Eau is one of the world's most iconic fountains, shooting water 140 meters into the air.

About this subject

The Jet d'Eau is the iconic fountain of Geneva, Switzerland, situated in Lake Geneva (Lac Léman) near the city's old town. Originally built in 1886 as a relief valve for the hydraulic system of a hydroelectric plant, it evolved into a major tourist attraction and city landmark. The current version, operational since 1951, uses two pumps consuming 500 kW of power, propelling 500 liters of water per second at 200 km/h. The jet reaches 140 meters in height, with each water droplet spending about 10 seconds in the air before falling back into the lake. The total volume of water suspended at any moment is around 7,000 liters. The water is drawn directly from the lake, untreated, and returns to the same ecosystem. At night, 12 halogen spotlights (9 kW total) illuminate the column. The Jet d'Eau runs daily except during icy conditions or strong winds, and is maintained by Services Industriels de Genève (SIG). In winter, it operates at reduced power. A notable incident occurred in 1993 when a swan collided with the support structure, causing damage that required months of repairs. Regular maintenance includes divers inspecting the submerged base. The Jet d'Eau is one of the few urban fountains visible from high altitudes, often photographed from aircraft flying over the region.
