The water jet

Located right in the heart of Istres, the Etang de l'Olivier is a jewel with France's highest water jet towering over it.

The jet d'eau, located more than 80 meters from the shore in the Castellan cove, reaches a record height of 50 meters.
Introduced in 2008, the Jet d'Eau is unique in France for its height, technical innovation and aesthetic prowess. A huge liquid flag, it symbolizes the vitality of the city of Istres. It also helps to oxygenate the Etang de l'Olivier.

Unique in France!

Technical innovation
The water jet is installed on a 6-metre square frame, immersed 50 cm below the water level for better integration into the pond. The stainless steel structure weighs 2200 kilos.

The water column is fed by a 125 horsepower pump, located 3.5 meters underwater.


In figures :
- Average jet height: 50 metres
- Water outlet speed: 120 km/h
- Flow rate: 80 litres/second
- Pump total power 92,000 watts

Note that the water jet can be switched off on days when the Mistral wind blows or when the weather is inclement.
