Jet d’Eau (Geneva Water Fountain)

The Jet d’Eau rises from a stone jetty at the Eaux‑Vives harbour where Lake Geneva meets the Rhône, and its white plume can be seen from every corner of the city and even from aircraft flying about 10 km overhead. Each of the two 500 kW pumps pushes 500 L of water per second through a 10‑cm nozzle, sending the stream up to 140 m (about 150 m at peak) at roughly 200 km/h; at any moment around 7,000 L of water hangs in the air. The fountain runs year‑round, except for brief maintenance periods, and its illumination changes for special events.

Historically, the jet began in 1886 as a safety valve for a hydraulic factory, shooting only 30 m. It was moved to its present site for the 1891 Federal Gymnastics Festival and the Swiss Confederation’s 600th anniversary, then rebuilt in 1951 with a submerged pumping station that now draws directly from the lake. Five retired technicians from Services Industriels de Genève monitor the jet daily, closing it when wind or temperature makes the spray unsafe.

Visitors can walk to the jetty on the left bank; on windy days the mist may reach the promenade, adding a refreshing splash. The Jet d’Eau has become Geneva’s emblem, a constantly moving landmark that blends engineering, history, and lakeside scenery.
