St Laurent

The building of the white water stadium in Saint Laurent Blangy is primarily a rehabilitation model of a former industrial site. The town council developed an ambitious project with an urban and social aspect : to create a torrent in the town centre and to facilitate the access to white water to school children, to prisoners near release, to general public…

In addition to the natural flow of the Scarpe river, the course in Saint Laurent Blangy is the first French stadium (and also the second of the world after the olympic course of Seo Urgel in Spain) to use a 9 cubic metres per second pumping station to bring water to the beginning of the river. This assures an optimal flow and a large navigation comfort.

The artificial river was excavated through an island formed between the channelled Scarpe lock and its discharge branch. A 9 m³/sec pumping station advantageously completes the gravitational supply of the river,  and also ensures the supply in water of the white water stadium, whatever the natural flow rate of the Scarpe,  by raising water to the start of the circuit.

Thanks to OMNIFLOTS mobile obstacles, this stadium can be adapted to all levels, from beginners to high level athletes.
