In investment the cost is infinitely cheaper than permanent protections and then on the aesthetic level one cannot disfigure a port like that of La Rochelle.

Jean-François FOUNTAINE, Maire de La Rochelle
Mathieu Dupont Directeur de Projets Risques Littoraux - La Rochelle
The Water-Gate © solution that has been chosen makes it possible to avoid touching the roads and doing heavy work. These devices are both light and quick to deploy.
Mathieu DUPONT, La Rochelle Risques Littoraux
Compared to the other products offered to us, Water-Gate really is the ideal solution. You unroll it, and it takes care of the rest on its own!
Dominique SIX, Natixis
For us, Water-Gate is an innovative product because it provides a technical solution, partly in terms of flexibility, but also in terms of emergency response thanks to its rapid deployment capabilities.
Jean-François SALMIN, Egis Eau
We’re always on the lookout for systems that can protect us in the event of water level rises, and we purchased the Water-Gate device. Our goal is to protect the RER C line, a very vulnerable asset, from flooding.
Philippe MAYMIL, SNCF

Risk of submersion: Water-Gate© selected by the city of La Rochelle

La Rochelle was badly hit by storm Xynthia in February 2010 (6 dead, 280 Million Euros in damage). Rather than rebuilding the identical, the city of La Rochelle has implemented a PAPI (Programme d'Actions de Prévention des Inondations / Flood Prevention Action Program). The decision was made to protect the entire population against the risk "Xynthia + 20cm".

5 steps towards active flood protection: FLOOD-READY

1. RISK STUDY

Study the flooding dynamics of the site. Cartography, HKWL (Highest Known Water Levels), Topography

2. HEIGHT OF PROTECTION

Define the target height for the flood protection (e.g. 100-year flood, 1000-year flood)

3. VULNERABILITY ASSESSMENT

Vulnerability assessment of the surface and networks for the given protection height

A COMPARISON OF FLOOD PROTECTION SYSTEMS

Flood protection: case studies

Protecting a building, a riverbank, a neighbourhood, a town, and underground spaces from floods.

Water Gate is an emergency flood protection device that complements structural solutions | Hydraulic structures, flood overflow zones, embankments, etc.
Portable or mobile anti-flood barriers must be integrated into flood prevention action programmes (PAPI), flood risk prevention plans (PPRI) and local protection plans (PCS).

The 3 typical flood protection setups

The Water-Gate© flood dam is a new and comprehensive flood protection solution. Thanks to its modular design, its different heights and its flexibility, it can fit all kinds of terrain: 360° perimeter protection for flat terrain – U-shaped protection on sloping terrain – sectional protection supported by a wall or embankment. A feature shared between of all these anti-flood systems: the flood should never strike the dam from the rear.

Supported by a wall

The ends of the flood dam rest on a wall (any type, height and gradient can work).

Fitting the natural slope of the land

The ends of the flood dam rest on a gradient (a bank, a slope) – it can even be undulating.

360° protection

Perimeter protection of up to 360°, covering several hundred metres (on flat ground).

Aluminium barriers

We pair our Water-Gate protection devices with the best aluminium solutions: narrow openings, support points for flexible barriers.

Pumps and motor pumps

No mobile flood protection system is totally watertight. We provide pumping solutions to collect water that has seeped through and discharge it beyond the dam: self-priming motor pumps or submersible pumps coupled with generators.
